Hello,
My daughters Pc is an acer E360 which has a custom motherboard made by foxconn FC51GM. I isolated the high speed fan noise down to the power supply.
Disconnected all case fans including the cpu cooling fan to do this. The Athlon XP 3500+ could almost run without the cpu fan just the heatsink connected. Only ran about 10 degrees higher with the brief disconection of the cpu fan.
The problem is that no matter what power supply I put in there the power supply fan runs at full speed and sounds like a jet engine. They run all run at around 1500 rpms. Even an Antec truepower which is supposed to run low and quiet unless the system is running at or near max.
This is a low power system CPU 45 Watts. ATI Radeon HD 4650 75 watts at full load which it never even comes close to. 2 gigs of ddr400. It runs windows 7 with ease. The noise is the same running windows XP or 7 not that this should make a difference.
This is a non gaming pc. Just surfs the web and does her home work with open office.
I tried speedfan to control the fanspeed but not sure how to use it or if it will work to control the power supply fanspeed. will try to find a speedfan tutorial.
Very very annoying to listen to. Doesn't bother her much but I know it should not be running at full speed constantly.
