FX Fan Noise

Is it just me or is there a really high tinging sound that accompanies the graphics card fan spinup?

I'm afraid I may have screwed up the fan when cleaning it out with compressed air.

Tell me it's normal so I can stop worrying xD

 

Are you talking about that high pitched sound that you hear, after the fan stops spinning? If so, then I have it as well, and I heard it was quite common, I've had the high pitched sound ever since I got the laptop (half a year ago) and haven't had any noticeable problems yet, so you shouldn't worry too much (although it is annoying if you aren't wearing any headphones).

 

My fan has no high pitched noises.

 

My fan did the same thing, but I had another problem where the computer would freeze in games. I had to ship it back for repairs, and when I got it back, they had replaced the motherboard with one that had 9c.20. It fixed the problem. Here is my comment on it:

I had to ship my P-7805u in for repairs, and when I got it back, they had replaced the motherboard. The new one has 9c.20. Basically this is the difference I noticed: With 9c.17, the GPU fan would rev up and down repeatedly when the temp was between 43 and 55C or something around there. This was super annoying to listen to and it was probably hard on the fan. Now with 9c.20, the GPU fan stays off completely until the temp hits 82C. This is way to high in my opinion, especially to have the GPU temp idle between 55 and 65C. The CPU fan is the only thing that cools it, and it stays on 24 hours a day even when the core temps are under 30C.

I bought the Notepal U2 cooler with fans that blow air into the computer and so the GPU now idles between 42-46 and I am going to place a filter in between the cooler and the laptop under the CPU so that not much dust collects inside. Even after these adjustments though, in games the GPU will generally hit 82, the fan will spin up to high, the GPU will go below 70, then the fan will turn off, then the GPU will warm up again... It is very nice though not to have the GPU fan turn on at all in older 3D games and not to have the horrible spin up/down cycles.

 

TBH the high pitched fan doesn't bug me much if it's normal and keeps the GPU cool. Just worried I may have blasted the fans with air and made them spin faster than they're supposed to ;(

Thanks for the responses guys!
