GT AP-15 Problem

post #1 of 11
Thread Starter 
I got 4 AP-15s today. I tested them all out before I put them in my case. Here's the problem. When I put them on my Megahalem, I get a high pitched "wizzzzzzzzz" sound. The sound wasn't there before I put them on my megahalem.

Is this normal? If not I'm going to RMA asap. I have two AP-15 making that sound and it's pretty annoying. The other two fans are running perfectly as intake and exhaust.

I have the same fans on my Pro Mega. My are very quiet. Not a fuss out of the two that I have. I'd send those back ASAP.

Also check the cables and take a peek at the fans. Maybe something is stuck. It sounds like a bad motor or bearings to me!

I'm sorry man. Don't get to sad! I'm sure the next two will be working just great. I love my GT AP-15 1850 RPM is amazing. They move a lot of air and keep my CPU cool.

are you sure its the fan? I don't have AP-15s but when I started using Higher cfm fans and using dust filters for intakes it would make a whistling noise but without it would be fine, might be a good idea to turn off intakes or take off filters to check. Just a suggestion

Before you RMA, try swapping with the other two fans and test them. You said the fans didn't make this noise in "free air". Sounds to me like either vibration or whining from the air passing through the HSF fins.

I took the fans out to hear them in free air again. Still has the whizzzzing sound.

Push the centre hub while the fan is off and try again.

Agreed. What Vestito says.
Hmmm could be some sort of turbulence going on. Do you have other fans near the heatsink? Like exhaust or intake fans? If you do, see what happens if you remove the other fans around it.
