After my local Best Buy replace the Motherboard, the CPU fan runs at max speed constantly from boot.
I checked SpeedFan and my Core temp is 28C, and everything else 40C-45C.
I've updated BIOS and reapplied thermal compound (AS5).
I normally use a 600W PSU and a HD 5770, but im waiting to get my PSU replaced and until then, im using the stock 300W PSU and a HD 4650.
My computer is a Gateway DX4300-03.
Phenom II X4
You are gonna need a 4-pin PWM fan to be able to lower the RPM's(noise)..3-pin fans are gonna need a fan controller to turn them down...BTW..since Best Buy changed it they should fix this for you...I mean you did pay a good deal of cash to get it repaired there right...then they should remedy this for you ASAP....
