Have you ever turned one that has ran that long off and then back on again? It's weird to see it struggle and skip for a minute from where the motor/bearing is so worn until it gets back up to full speed.

that's what fans are designed for. PC gaming autists are the only ones who think fans need extra special fan curves and zero rpm modes and other asinine nonsense, along with 50 million fag ass rgb leds

>What kind of witchcraft.....

the ball bearing. You also want metal blades, mendards sells kickass metal fans for cheap.

>>106598957
bearings usually last at least 30,000 hours, 3 years is a bit under that

What's the loudest exhaust fan I can buy for my PC?

>>106598957
brushless motors

>>106598998
5000 rpm delta industrial fan, and stick a piece of plastic in it

>>106598957
the stator, rotor and coil shit confuses me 2bh
still seems like witchcraft after they say magnetism and electrons and shit
people say they understand it beyond a conceptual level but I don't at some point I'm just accepting that these tiny things exist and usually behave in predictable ways

>>106598957
Eventually, you'll turn it off, and when you turn it back on again it'll take quite a while to actually start spinning, all you're hear is the groan of the motor trying to get things moving.

And, mind you, that's performance AFTER planned obsolescence enshittification.

need some lesser retard to "build the ultimate box fan." tired of the basic ones. i want:
>five speeds or more
>silent or near silent reversible motor
>front facing switch knob
>easy to clean, magnets instead of screws
>no vibration, robust materials/components
>integration with 20x20 standard filters
>free and open source
>rf remote (no BT, no WiFi, just basic RF)
>zero, and i mean ZERO lights

>>106598998
38x80x80mm 2U server case fan

>>106598980
Got one that's close to 10 years old, full of dust and vape residue. I have to shove a chopstick through the cage and help it start spinning at first

>rf remote (no BT, no WiFi, just basic RF)

Well that's a bit of a contradiction.

>>106600891
yes.

>>106598957
Motors don't appreciate being started and stopped so if you just don't turn them of and leave them on lowish rpm they can last an absurd amount of time, this is for brushed
brushless motors are essentially immortal, really impressive technology that i can't fucking believe we've only commercialized because the Chinese did so
