Small sound coming from fan area

[feathers]

Hi,

I installed SpeedFan yesterday, and shortly after I started hearing this barely audible sort of "screeee.. screee" coming from the fan area. I can hear the fan is working fine, and SF says my temps are normal (around 48c to 50c when idle, maxing at just over 60c when streaming video or playing a game) so my fan doesn't seem to be dying. But I don't know anything about computers, so I don't know.

I talked to an ACER guy (my laptop is an Aspire 5252) and he said use an air duster to clear out dust. I did, and I think I did it right, but the little whine is still there.

Do I need to send my laptop in for repairs?

I have noticed noises like that in a lot of computer components and laptops. For example, my video card makes an audible noise like the one you described that is not the fan during the loading screens of certain games. From what I have read, this is not a problem, and is just a byproduct of current flowing through certain components.

Oh, okay. Thank you.
