Hi rz1-rulz, and welcome to BleepingComputer.

What is the make and model of this computer?

Unfortunately there isn't anything that you can do about the PSU fan short of replacing it with a quieter PSU. The CPU fan could be replaced with a quieter one if there is sufficient space to do so. I would suggest not trying to change the fan speed as it could result in overheating your CPU.

Why are you considering changing the CPU?

A little about cooling "theory".

Smaller fans = more blades, rotate faster to move air. Faster, more blades usually equals more noise.
Larger fans = fewer, larger blades, rotate slower to move the same or more air. Usually equals a quieter fan.

Terms to pay attention to when fan shopping. CFM = Air Flow generated measured in Cubic Feet per Minute.
dB = decibel. The amount of sound generated by, in this case a fan. The fan makes two separate noises. One being the sound of the electrical motor. The other is the sound of the air movement created by the fan. The air movement is usually what we hear and attempt to reduce without losing any cooling ability.

That may or may not help. It depends on the design of the current CPU fan.

Since you state the PSU fan is loud as well then it is likely the fan you are hearing more\most since it exits to the outside of the case.

Apparently there is still a problem with the quick response. Earlier today I posted that I had misread post #4, and that was why I had asked why you were replacing the CPU. :blink:

The power supply fan to me seems like its making a loud but smooth sound and the CPU fan is making a loud annoying sound.

Sorry. But my best guess for a name would be Generic. With the fan spinning the sticker on the hub can`t be read. It is probably the original fan. Bought in bulk by Compaq (now owned by HP) and used in thousands of PCs.
The new fan will probably be quieter. I would bet the new heat sink & fan will cool better.
