Trying to make a quiet PC

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.

Any decent/good cooler used along with a silent fan should do the trick really , as you have already under volted the cpu .

Budget?

Download software which can control span speed
Speed fan is 1 i knw.......I havent tried. So chk out.

Buy Dampening/Acoustic Absorption kit from KMD or new case 'CM Selio 500'. Intel 65nm CPUs stock cooler w/ copper base (Q6600 cooler) will lower temps 6-7c further, so fan rpm wont accelerate if no heat. Use rubber washers to mount case fans + HDDs. Cut all honeycomb mesh on all fan slots in case.

For noise v/s cooling, go for a large cooler like the Thermalright U120 EX/ True. Can be used with a slow noiseless 120mm fan, or even without a fan, provided your existing case has sufficient air circulation.

I've recently put together my standby PC and notice that the noise signature of the 120mm cabinet intake fan on my Zebronics Bijli is less shrill and more comfortable than the 70mm AMD S939 CPU fan.

I don't know the size of your CPU fan but if it is 80mm, you get these 80mm to 120mm adapters that you can probably get through KMD and use with your stock cooler. IMO, this is a simple solution.

Cooling experts in this forum should be able to fill you in on the myriad of options w.r.t. stock cooler replacements.

Thanks to all who replied.

My budget is Rs 2,500.

I would rather not go the KMD route, if I can't find it locally or from
Mr. Amarbir, Lynx Chandigarh, then I wouldn't go for it.

@axeman
I do like the idea of going fanless with the Thermalright U120 EX/ True
but it would be safer to use a quite fan as well.

I would like to know if anyone has tried the fanless approach, and with
which CPU cooler.

Please suggest a CPU cooler that you know from personal experience to
be quiet and effective.

i would rather suggest a dead silent CM 45CFM 19dbA fan on the TRUE.. Its totally inaudible..

for ur work any cooler will run fine passive . even while oced TRUE etc can handle 3.6ghz c2d easily with safe temps if u have good airflow in cabby .

but i would suggest u to get sunbeam CCF 92 / 120mm , it comes with fan controller , u can set the speed if u feel its noisy ...

TRUE is not available now and only Black edition is available which costs 3.5k .

Here is some more info,
I shifted the computer to the AC-room and now I have:
CPU temps: IDLE-33c, LOAD-46c,
CPU fan: IDLE-1250 RPM, LOAD-1900 RPM

At 1250RPM the fan is inaudible, though under load it can be heard.

I guess that means I need a CPU cooler which can handle the load with the
fan running at 1200RPM.

I am leaning towards sunbeam CCF 120mm, though I am a little worried
about the case clearance needed.

you can get a vendetta 2 or TR Ultima90 if you are worried about the size and case-cable management.
