Fan blades are dangerous. So dangerous, in fiction, that if you get too close, even a humble household ceiling fan might take your head clean off. Sometimes the blades are sharp or serrated, but the most blunted of fans turn into deadly shredding machines when moving fast enough.

These are most commonly encountered in narrow spaces where they cannot be easily avoided, sometimes as part of a DeathCourse. In video games, it is sometimes possible to slow them down or break them by jamming a rod or beam between the blades, allowing the player to get past. Some characters employ them as weapons. They can also be deadly if a rope is involved, with one end looped around the victim and the other end looped around the axis of the fan.

This is TruthInTelevision to an extent, as fans, including airplane propellers, can be very destructive and very deadly; after all, this is the same principle on which a blender or lawnmower operates. That said, in fiction this effect tends to be greatly exaggerated; an ordinary domestic fan with ordinary plastic or wooden blades typically won't give you worse than a nasty bruise.

Supertrope of HelicopterBlender and TurbineBlender. Compare DeadlyDisc. Not to be confused with PaperFanOfDoom or that [[ Urban Legend]] prevalent in Korea that says sleeping in a enclosed room with a fan on can be fatal.

* A TV commercial has a man get around quickly by hopping around on bent stilts. At the end of the commercial, he hops up and down in his apartment, right under a spinning fan. He hops a little too high and is immediately turned into [[ChunkySalsaRule fine red paste]], despite the fan barely touching him.

* Rick Chalker from ''ComicBook/XFactor'' attempts to use [[{{Cyborg}} rotors grafted in place of his hands]] as weapons, extremely incompetently.

[[folder:Fan Fic]]
* Taken to its most absurd conclusion in ''Fanfic/CalvinAndHobbesTheSeries'' when [[{{Technopath}} Electro]] captures Andy, Socrates, and Sherman, dangled from the ceiling by power cords, and set to slowly descend into a ''blender''. As in, a normal, household blender.
* ''Fanfic/TheGreatAlicornHunt'': This trope is both Discussed and Averted in chapter 38 when three batponies find themselves dealing with a runnaway airplane.
--> "What do we do? We can't land this thing!!" Moonpenny shrieked over the redlining motor. "It'll just lawnmower its way down the Midway!"

[[folder:Films -- Animated]]
* In ''WesternAnimation/FindingNemo'', during the Tank Gang's first attempt at jamming the filter, Nemo swims inside the filter to jam the fan with a pebble, but unfortunately it turns out that Nemo didn't jam the filter hard enough, and as a result the other fish actually had to stick a fake plant inside the filter to get Nemo out before he gets sliced into sushi.
* Subverted at the end of ''WesternAnimation/{{Rio}}'' where [[DragonInChief the evil cockatoo Nigel]] is actually revealed to have survived being shredded alive by an airplane's propellers, and as a result it also caused him to lose all of his feathers.
* The Omnidroid in ''WesternAnimation/TheIncredibles'' could do this with its tentacle-like legs.

[[folder:Films -- Live-Action]]
* Charlie and Grandpa Joe narrowly escape one of these in ''Film/WillyWonkaAndTheChocolateFactory'', during the Fizzy Lifting Drinks scene.
* In ''Film/{{Alien 3}}'', one of the prisoners (Murphy) is killed in a ventilation fan.
* In ''Film/IdleHands'', one of the girls is killed by the fan in the school ceiling.
* Franchise/IndianaJones examples:
** Played straight in ''Film/RaidersOfTheLostArk'', where a burly German mook is fighting with Indy and ends up getting hit with an airplane propeller.
** Averted in ''Film/IndianaJonesAndTheTempleOfDoom'' when Indy wraps one end of his whip around a {{Mook|s}}'s neck and the other end around the ceiling fan in his room; the thug is pulled into the fan blades and breaks his neck.
*** Both of the above mooks were played by the same actor, [[ Pat Roach]].
** And a ship's propeller tears apart a boat in ''Film/IndianaJonesAndTheLastCrusade'', although nobody dies this time.
* In ''Film/{{Razorback}}'', the eponymous boar gets killed by a giant industrial cooling fan.
* ''Film/TheMummy1999'': Rick O'Connell hoists Beni up as an interrogation-technique, as if he's about to ram the little creep's head into a ceiling fan. Subverted because Beni spills his guts rather than field-test this trope's validity. Bonus points for the [[AudibleSharpness metallic ring]] of the fan's blunt wooden blades.
* ''Film/ArmyOfDarkness'': Ash incorporates a windmill's vanes into his battle-refitted Oldsmobile, then drives this whirling mega-fan into the undead horde and sends flying every one that fails to evade.
* One slimy bit character in the absolutely terrible B-movie ''Superfights'' is killed by the villain's mooks by having his head held up to an ordinary bedroom ceiling fan -- [[MadeOfPlasticine which cleanly slices off the top of his skull.]]
* At the end of ''Film/CatsEye'' the little troll is thrown into a normal-sized fan and gets sliced as a result.
* A man has his skullcap sliced off by a ceiling fan that has machetes attached to the blades in ''Killing Spree''.
* Frankie's head is shredded by an engine block fan in ''Film/FinalDestination3''.

* ''Film/MissionImpossibleGhostProtocol''. Brandt has to infiltrate a computer server room via the heating vents, which involves leaping 25 feet into a vertical shaft at the bottom of which is a large cooling fan, and hope his metallic suit will keep him suspended above a remote-controlled robot with a large magnet trundling beneath it. As a RunningGag in the movie is the failure of the various gadgets the IMF team is equipped with, this plan does not fill him with confidence.
* Chucky gets thrown into a giant, flashing ventilation fan at the end of ''Film/ChildsPlay3''.
* [[TheDragon Wesker]] uses one of these to kill a member of the group in ''Film/ResidentEvilTheFinalChapter''.
* ''Film/Leprechaun2'': The Leprechaun kills Ian by casting an illusion of a girl he's interested in taking her top off in front of him, but he's actually sticking his head into two rotary blades.
* In ''Film/HardcoreHenry'', Henry breaks off the grate of an air conditioner unit, then throws a mook head first into the fan, which shreds him.

[[folder:Live Action TV]]
* ''Series/{{Alias}}'': One episode ended on a {{Cliffhanger}} with Sydney struggling not to get pulled upwards through an {{air vent|Passageway}} into a huge fan.
* Twiggy's character bites it this way in the ''Series/TalesFromTheCrypt'' episode "The New Arrival." The ceiling fan has some sort of jagged blades affixed to it and lowers itself down to take off her noggin.
* In the ''Series/DoctorWho'' episode "The End of the World", the Doctor must [[DeathCourse navigate a series of these]] in order to reach an [[MalevolentArchitecture otherwise inaccessible]] switch.
* The ceiling fan decapitation variant was busted by ''Series/MythBusters'', who found that even an industrial fan, while probably lethal, would be unable to decapitate a person.
* In ''Series/HerculesTheLegendaryJourneys'', one villain used deadly metal fans as part of his method of brainwashing people into being loyal followers of his cult. Iolaus manages to trick the villain into falling into the fans during their fight, shredding him in the process.
* Subverted on ''Series/MyNameIsEarl''. After Earl tipped over his ex-wife's trailer home on a bender, and was unable to rent a crane to lift it up again, Joy and Darnell were making do with the sideways trailer. The ceiling fan ended up being on a wall instead of on the ceiling, and it lopped off one of Joy's pigtails, much to her anger. Otherwise, it did no real harm or damage.

* Konrad Knabe, in his ''Lapin lentotiedustelijat'' (Lappland Reconnaissance Squadron) describes a situation when the wife of one of the pilots accidentally walks into the spinning propellers of Dornier Do 17. Messy.

* In ''Roleplay/RubyQuest'', one room has a catwalk crossing over a pair of giant fans. They're proven deadly in a flashback, when Ruby shoves Stitches into them.

[[folder:Tabletop Games]]
* ''TabletopGame/{{Paranoia}}'' adventure ''The Yellow Clearance Black Box Blues''. One of the traps in the Mission Three "dungeon crawl" is a giant exhaust fan. If any of the {{P|layerCharacter}}Cs is sucked into it they'll "become thousands of julienne fries in seconds."

[[folder:Video Games]]
* In ''VideoGame/BanjoKazooie'', Clanker's belly contains rapidly-moving fans with serrated blades, while the Rusty Bucket is fitted with deadly propellers. The sequel ''Banjo-Tooie'' has these in areas of Jolly Roger Lagoon that link to the Glitter Gulch Mine and Grunty Industries levels. Unlike the previous game there actually is a way to get rid of them (for good) to make your life easier; to do so all you need to do is freeze them with ice eggs and then blast them with grenade eggs to destroy them.
* ''[[VideoGame/TheElderScrollsVSkyrim Skyrim]]'' features large rotating blades coming from the ground in Dwermer ruins.
* In ''VideoGame/ConkersBadFurDay'', underwater rotating fans are encountered during the [[DownTheDrain U-Bend Blues]] segment.
* In ''VideoGame/TheLegendOfZeldaOcarinaOfTime'' and ''[[VideoGame/TheLegendOfZeldaMajorasMask Majora's Mask]]'', Peahats attack using these.
* The ''VideoGame/SonicAdventure'' enemies E-06 Spinner and E-16 Electro Spinner are fitted with these. The game also features a HelicopterBlender obstacle in Speed Highway.
* In ''VideoGame/HalfLife'', there are several instances of this. The first time you have to pass by an exposed fan, a headcrab demonstrates exactly [[LudicrousGibs what will happen if you touch the fan blades]]. The trope returns in ''VideoGame/HalfLife2'', in the "Nova Prospekt" chapter: the only way to cross the fan in the vent shaft safely is by jamming the blades with something sturdy enough to break the motor.
* At one point during ''VideoGame/CallOfCthulhuDarkCornersOfTheEarth'' you have to flee into the sewers, but the way is blocked by a sharp fan. You have to break one of the blades to slow it down and open a passage and even then you'll get chopped (but not always killed) if you're hit.
* One of the Nightmare Realm levels in ''{{VideoGame/Gauntlet}}: Dark Legacy'' has several huge fans blocking your way. You can hit the "slow down" switch to make it past them.
* Some levels in ''[[VideoGame/MeatBoy Super Meat Boy]]'' have giant fans that can propel you through the air. Get too close to the blades, though, and SPLORCH!
* In ''VideoGame/MonsterBash'' there are spinning ceiling fans which you have to shoot the motors of in order to stop them from hurting/killing you.
* One of the [[StageFatality stage fatalities]] (Blade's stage) in ''VideoGame/EternalChampions'' lets the player knock their opponent into the huge fan in the center of the stage. LudicrousGibs ensue.
* In ''VideoGame/LabOfTheDead'', the Handheld Fan rotor can cut a zombie's jaw off.
* ''VideoGame/DeadSpace'' contains several menacing ventilation fans.
* ''VideoGame/{{Bulletstorm}}'' has a skillshot called "Sucker" for killing an enemy by knocking them into a fan.
* There are a series of these in ''VideoGame/EpicMickey'''s "World of Gremlins" dungeon (which imitates the "It's a Small World" ride). They spin too quickly for Mickey to easily get through unharmed, but he can use paint thinner to erase some of the blades long enough to pass by unscathed.
* The ''VideoGame/{{Unreal|I}}'' Deathmatch level [=DmDeathFan=] features a big rotary fan at the very bottom of the level. Players being pushed into it, naturally, die. This is also one of the things the player has to avoid in the singleplayer level "Rrajigar Mines". ''VideoGame/UnrealTournament2004''[='=]s Deathmatch level [=DM-Insidious=] also features one, in the center of the map.
* ''VideoGame/OpenArena''[='=]s deathmatch level pxlfan also features a big deadly rotary fan at the very bottom of the level.
* Featured prominently in ''Videogame/MadWorld''.
* An obstacle in some levels of ''Literature/ShadowsOfTheEmpire''.
* Seen in ''VideoGame/WorldOfWarcraft'', in a quick shoutout to ''Franchise/IndianaJones'' in the Uldum questline. At one point "Harrison Jones" is in a fistfight with an enemy while you finish a nearby quest. [[TakeYourTime You have plenty of time to finish it]], of course, but those who remember the movies will know exactly what will happen when you hop in a nearby airplane...
** In Deepholm, Stormcaller Myra uses the rotary fan of an airship to interrogate a Twilight's Hammer leader into giving you some information. After all is said and done, Myra reveals she had air elementals supporting the Ogre's weight and he wasn't in any real danger. The Ogre, knowing that his superiors would give him a FateWorseThanDeath if they found him decides to kill the air elementals and let himself fall into the fans, dying in a spray of LudicrousGibs.
* ''VideoGame/TombRaiderII'' and ''[[VideoGame/TombRaiderIII III]]'' use giant fans in vents that can quickly kill you if you get too close. The ones underwater can also drag you into them if you aren't careful. Most fans have to either be avoided, turned off, or have the fans spin slower so you can pass through without harm.
* ''VideoGame/DeadRising'' and its sequels feature the auger - a man-portable giant drill. Drilling it into a zombie will cause it to stick to the drill, turning ''[[GrievousHarmWithABody the zombie itself]]'' into a deadly rotary fan. (Until after its limbs fly off after striking a few other zombies, leaving only a torso on the drill.)
* The second stage of ''VideoGame/TheNinjaWarriorsAgain'' has these. They will pause for a while, giving an opportunity for the player to get through. Mooks, on the other hand, [[TooDumbToLive blindly walk into these]] when they are spinning.
* This is one possible way to deal with the mooks in the [[TheProblemWithLicensedGames godawful SNES video game adaptation]] of ''Film/TheShadow''. It reduces the tediousness of the game somewhat.
* ''VideoGame/WorldOfGoo'' features these as hazards in some levels.
* This is one of the special interrogations in ''VideoGame/ThePunisher'' video game.
* ''Franchise/MortalKombat''
** This is the stage fatality in the Prison stage of ''VideoGame/MortalKombat4'', naturally. Though the fan is starting up at the beginning of the match and gains momentum, it starts speeding up when the stage finisher starts. It's also unique in that it doesn't have the winner simply uppercut the opponent into the thing, but rather grabbing an arm and a leg and spinning just fast enough to throw them into the blender without missing.
** In ''VideoGame/MortalKombatX'', we have Kenshi, basically a blind samurai with [[MindOverMatter telekinetic powers]], whose fatality involves throwing his sword and commanding it to spin mid-air, then lifting up his opponent and moving them towards the spinning blade.
* Philip has to pass such a fan in ''VideoGame/{{Penumbra}}''. He even comments that it "could slice meat in a millisecond". Like in ''Half-Life 2'', he has to take an object and jam it in the blades to stop the motor.
* In ''Atomic Robo-Kid'', one type of enemy resembles a corridor-spanning rotary fan (with a central eye) that slowly advances toward the player. Apparently, its name is [[JapaneseRanguage Brade]].
* ''VideoGame/DeusEx'' has the occasional deadly fan, normally large metal fans only accessed by doing the usual vent-crawling. [[ Bob Page seems to be a fan of them.]]
* Some levels of ''VideoGame/QuakeII'' have these. One level has an alternate route that requires you to swim through one. In another, the fan has to be turned off to proceed.
* In addition to providing [[VentPhysics air currents that the player can utilize]], the fans in ''VideoGame/{{Turok}} 2'''s Primagen Lightship stage can also be a death trap.
* In one of ''VideoGame/SoldierOfFortune'''s cutscenes, a {{mook|s}} is sucked into a fan and reduced to LudicrousGibs when Mullins activates the ventilation system. The player can also suffer the same fate if they're not careful.
* ''VideoGame/{{Battletoads}}'' has the Sucka traps, which pull 'Toads in with VentPhysics and will grind them up head first.
* From ''VideoGame/TheWhiteChamber'', there is a giant fan located on the ship. Later on in the game, you find out that [[spoiler:Sarah threw one of her colleagues into it, killing him]].
* VideoGame/RatchetAndClankIntoTheNexus has rotating blades within the ventilation of the Meero Museum. Fortunately, they do not spin fast enough to pose a threat to the player, and only serves to point them in the right direction.
* In ''Star Wars: Episode I The Phantom Menace'', one early level has your character traversing ventilation shafts containing spinning fans that can be fallen onto. If you fall onto one, you are instantly chopped into small pieces, with the pieces still screaming for a moment afterwards.
* The infamously NintendoHard ''Series/StarTrekDeepSpaceNine'' video game for the Sega Genesis had this on [[ThatOneLevel the Bajoran Cave level]], with fans that created air currents that would either suck Commander Sisko in or push him away and cause him to fall off platforms.
* When Ark confronts Dr. Beruga on his giant airship near the end of ''VideoGame/{{Terranigma}}'', Beruga gloats that his jet boots will allow him to simply fly away from the crashing ship to safety, leaving Ark and his friends to die in the wreckage, only for a large fan behind him to unexpectedly begin spinning, dragging him towards it. The screen [[GoryDiscretionShot fades to black before he contacts it,]] [[SubvertedTrope only to suddenly flash blood red with a sickening crunching sound]].

* ''WebAnimation/LlamasWithHats'':
-->"The people have spoken. ''Viva la Resistance!''"\\
"You pushed the resistance leader into a ''giant fan''."\\
"He was a traitor and a scoundrel!"\\
"He was trying to stop you from pushing other people into a ''giant fan''."
* ''Machinima/RedVsBlue'' mocks the trope in the third season, using the giant fan in Zanzibar:
-->'''Tex''': Then we'll have to get past the giant fan...\\
'''Tucker''': What, that thing? It's moving at like two miles per hour!\\
'''Tex''': I didn't say it'd be ''hard'' to get past.

[[folder:Western Animation]]
* The ''WesternAnimation/CelebrityDeathmatch'' episode "Fandemonium I" features a giant killer fan wheel during the Adam Sandler vs Chris Rock fight.
* Subverted in one episode of ''WesternAnimation/FamilyGuy'' where a fight against Peter Griffin and Ernie the Chicken Man ended with Ernie supposedly being shredded alive by propellers at an airport... but like always, it turned out that Ernie survived.
* In the ''WebAnimation/HappyTreeFriends'' episode "Party Animal", Cuddles gets shredded by a ceiling fan.
* One of Kenny's deaths in ''WesternAnimation/SouthPark'' occurs when "Jimmy the [[ExactlyWhatItSaysOnTheTin Don't-Hold-On-To-A-Magnet-While-Someone-Else-Uses-A-Fan-Nearby]] Falcon" demonstrates on him by handing Kenny the magnet while turning on a giant fan.
* ''WesternAnimation/TheSimpsons'': In "Angry Dad: The Movie", Bart has some fun while his family is out by trying a long rope to himself and a ceiling fan so he can get pulled through the room and break many objects as it spins. When he realizes he's close to the end of his rope, Bart manages to untie himself before he gets shredded.
** In "Marge Gets a Job," the Simpsons' house starts to tilt as the foundation sinks. Maggie slides toward a fan and tries desperately to crawl away. Homer rescues her.

[[folder:Real Life]]
* The well-known phenomenon of birds getting killed by airplane propellers or jet turbines. Not likely to turn out too well for the plane, either.
** There's a bumper sticker floating around there: "Eagles may soar, but weasels never get sucked into jet engines."
* Airplane propeller blades and/or blade tips are usually marked with yellow and/or stripes to warn anyone from walking into spinning propeller when the propeller is revolving. Still, accidents do happen. Amazingly, people are known to have survived such incidents.
** Skydivers are taught ''always'' to approach an airplane for boarding from behind. In Estonia, an experienced skydiveress walked into the propeller of the jump plane in 2008, with fatal results.
* To avoid this trope being a problem with small handheld and desktop fans, sometimes the blades are made of soft foam that is harmless to your fingers.
* One of the possible means of making ceiling fans less dangerous is to use large, softer blades that would deform or detach from the fixture if it strikes an obstruction, so that the potential for severe damage to someone is reduced.
