Accidentally hitting/touching a case fan while the computer is on?

post #1 of 3

Can this damage the case fan?

I have a corsair 750D and I was checking to make sure the front intake 140mm case fans were spinning, so I took the fan filter off and when I pushed it back in, there is no grill to it hit the fan on top and it stopped spinning and made a very loud noise.

This happened with my radiator fans on my NZXT kraken x60 before, when I accidentally hit it with my finger and it broken the fins off.

The fan seems to be spinning fine but can this cause damage or lower the RPMs?

think you answered your own question here biggrin.gif

but normally no it wont harm the motor, usually it'll just start spinning back up. it would harm the motor if you kept it held down and don't allow the motor to spin at all. eventually all that electric energy will harm the fan, but not for just an accidental touch type scenario. the worst thing you can do is what you already did. breaking a fan blade off = dead fan. you cant use an unbalanced fan like that and will need replacement. technically it's still pushing air, but the imbalance from missing part of 1 fan blade will cause ALOT of vibrations and that in itself will cause other problems within the system.

Well, the fan DID NOT break.

What I wrote was saying that it happened to me before AND it broke then.

Now, it just stopped spinning but began spinning again but sounded weird.

I'm noticing the RPM's now are lower than the other 2 EXACT same fans, which is interesting.
