Hi

My system configuration is:
Intel E7400 @2.80GHz(stock) on stock HSF,
Gigabyte GA-G31M-S2L Motherboard
Kingston 2x2GB DDR2-800 RAM
Seagate 500GB 7200.12 Sata HDD
LG Sata DVD Writer
Coolermaster RS-380 PSU
Generic Case

I have undervolted the CPU to 1.072V from 1.2625V stock VID.
I have removed the standard heat-transfer paste and used
OCZ Freeze paste instead.

The CPU temps are: IDLE-36c, LOAD-52c,
and the CPU fan is: IDLE-1700 RPM, LOAD-2250 RPM
This is in a non-cooled room.

The PSU fan is almost inaudible.
The CPU stock fan is audible/irritating and I want to fix this.

I use this system for Software development/Internet access.
The CPU load is light except for when I am compiling code
or when running a Virtual-PC session.

Please suggest a CPU cooler that is quiet or near inaudible
for my system usage.

Thanks.
