What Does This Tell You

Over the last week or two noticed a very slight constant whistling noise from my pc tower....it's not enough to start annoying me (yet)...
however....
what i have noticed is that the noise gets slightly more pronounced when doing something like closing an open window or opening a program.
Any idea where it may be coming from?
:beer:

It may be your fans on case or processor usually its the case, It may need cleaning out, not sure why closing and opening a window would do this so much, but the whistling noise is a symptom of a fan

I cleaned the fans a few weeks ago with a can of compressed air.

Sometimes they just need replacing depends on how old and how much use they have had. Normally cleaning them is fine for months if not a year but on occasions I have had to replace some before now admittedly they were quiet old 3+ years

I took the cpu fan off and cleaned the heatsink using the can of air....
just wondering...
that by blowing air at the heatsink i may have caused some damage?

How about the psu fan?

I strip mine down and clean it but I do make sure all power is off and let it discharge for a while. They get very dirty inside

Little unsure about striping mine down.....

i did give it a slight blow with the air (directed at the fan)

however i doubt if that really did a good job of cleaning it.

If it is the PSU, I suggest you do not strip it down... Try starting it with the case off and seeing if you can hear which fan it is... If the PSU, then get a new PSU and replace it.. Best and easiest way...

If the case fan (if you have one), they are easy to replace as is the CPU fan...

Worst case; It might be a capacitor on the motherboard!

You say the whine changes when you open / close windows and applications. I've heard things like this from some of the 'cheaper' brands of motherboards (cheap components like non-solid capacitors tend to have a high pitch whine before failing or bursting!.)

What's the make of the motherboard? A few of the high end mobo makers were caught out when they were sold a load of cheap components a few years back!
