Case Fan strange noise

zyklon · Nov 15, 2011, 11:10 PM

Ok, so I have recently purchased 2 x Aerocool Sharks 140mm which are attached to a fan controller. Lately, one of the fan started to make a strange whirring noise if fan speed is set to MED or HIGH. Moreover, if I move my hand or use something to block some of the airflow coming out, the noise stops, but starts again as soon as I remove it. Any ideas or fixes? Or should I just send it back?

I had that problem in one of my cases with a bottom 80mm fan I ended up putting a bit of tape over some of the holes as it wasn't seen, you could try the other fan to see if it makes the noise aswell.

Bearing is bad. Send it back.

I tried adding some oil lubricant this morning but didnt have enough time to test it out for a long period, though the sound was almost immediately gone. I'll have a better look once i get home.

Anyway, i guess this is only a temporary solution and the fan will fail at some point later on...

the noise only occurs when the fan is set to a horizontal position...guess its the bearing then
