Default Need an inaudible cpu/heatsink..non-overclocker. Advice?

Hello all. Long time lurker. First time poster.


Lately I have been in the market for a silent CPU heatsink/fan. Let me make myself clear. I don't mean 'purrs like a kitten.' I mean so silent it can only be heard from about a foot away or less. I have spent countless hours reading reviews on many different brands and products. Unfortunately it is impossible to determine the value of any product due to too many conflicting conclusions. Some say 'this fan is barely audible' while others say the same fan 'can be heard over everything else in my case.'

To be clear, I do not overclock. This computer is only being used for internet browsing and occassionaly some applications that require a little more processing power, such as recording tv and video conversion. Currently, my cpu fan keeps my pc between 42C and 45C at all times at 1650 rpm. I can't really say it's too loud. It just makes a kind of low whinning pitch that I'd like to do without if I can. In other words, I'm not looking for 'serious cooling,' just a fan/heatsink that will stay silent at 1650 rpm while providing adequate cooling.

I have an Intel Core 2 Quad Q6700 @2.66GHz HTPC. I should also point out that my motherboard has a pre-installed non-removable metal backplate under the CPU, making the installation of push-pins impossible. Also, my case will not allow anything larger than 120mm x 120mmx 155mm.

Edit: I seem to have made an error in my measurements. The area around my cpu is L 120mm x W 140 mm . And my case cannot be closed unless the fan/heatsink is under H 145mm. Thank you.


Any assistance would be greatly appreciated. Thank you.

i say scythe shuriken with the fan below 1k rpm.

if it was a regular pc, 212+ fanless or close to

the best air coolers do wonders on fanless when mated with a non overclocked/underclocked 45nm or so cpu.

Mugen 2 or the Ninja 2 wouldve been my choice for almost fanless rigs but with your space limitations, undervolting the fans on whatever cooler can fit would probably be your best bet. The stock fan on the Shuriken isn't bad at5V. Best check with Silent PC Review (SPCR) if you want hard numbers. Also are you sure its just your cpu fan? Sometimes the PSU and hard drives can give out quite some noise too. My 7200.10 Seagate for example was louder than my entire rig, and still is.

Wrong-o for both suggestions. Sycthe Orochi, with or without the fan. Dead, dead, dead silent.

Edit: Scratch that, Orochi is probably too tall, even without the fan.

I've used the shuriken on a couple HTPC builds, and I can't even notice there is a fan. My main HTPC is an overclocked E8500 and it cools it with no issues.

Orochi's a pig to use. There's going past the point of reason and that's certainly one of those cases.

On a side note I wonder if scythe will make a copper version of it.

Most full size after market coolers are 159MM tall.

And cooling a 65NM quad with minimum noise eh. Your gonna have to dig deep into your pockets.

I've got this big boy on my quiet machine. I had the fan unplugged for a couple weeks with no problems.

I put a 140mm Noctua on the top.

Scythe grand kama cross ii or something.

That is likely the ugliest heatsink I've ever seen.
