cheers
dont care about prices

I run a Nexus 120 on the Ultra-120 Extreme and its pretty quiet at 12V since the fan is deep inside the case. Sleeve bearing fans aren't supposed to be used for heatsinks but screw that

The producy code for mine is SFF21E
I do overclock my C2D 6750, and the fan spins at around 900 rpm under load. I don't think I can hear it at all, even with the Tri-Cools on my P182 set to low. The only science I have for this is that when the system is idling, the noise levels are the same, leaving aside noise from the disk heads.
And this model has open corners, which will suit the bullshit fan retaining wire that comes with the TRUE.

HTH, and happy new year

Scythe has a line of Slip-Stream fans, such as this 800rpm model that may be the quietest 120mm fans around.....the 500rpm fan is even quieter than this one.

But the real question.....just how much airflow do you need to maintain a reasonable temperature? Check the CFM numbers.....they may not be 100% accurate, but probably fairly accurate for comparisons. I suspect the bearings on these Scythe fans are much better than those sleeve bearings on the Nexus.

Plus.....Scythe fans usually will start spinning at much lower voltages than the Nexus, making them quieter.

Well iam using a Antec P182 which should provide some barrier to sound
Was considering getting the nexus one:

or
http://www.pccasegear.com/prod3652.htm (not sure if this is quiet)
I must get everything from that site :p

Hello,

I'll second the Scythe Slipstream suggestion. If you will have it controlled, then I'd use the 800RPM model, and if you need to run it uncontrolled, then the 500RPM model will be best.

I have the 92mm version. VERY quiet fan.

I don't know about those slipstream fans. My friend put one on his thermaleright hr-03 plus for for 8800 gtx, and after listening to it, I could swear my sflex fan was quieter. The slipstream had a slight click to it, where as my sflex is dead quiet. These were both the 800 rpm models. I was going to replace all my sflex with the slipstream fans but now I've decided to stick with them...

Are you controlling the fan voltage with the mobo bios, or with a fan controller of some kind? You are one of the rare folks reporting clicking these days, and cmthomson sez this is likely a mobo/bios problem. So you can be a big help to all of us by providing details.

I believe my friend is using the bios to control his fan. Its an Asus mb with q fan...

If you don't OC, you don't even need a fan for it. I guess that would top the list of most quiet solution. I assume that your case has an exhaust fan in it.

Noctua doesn't make a 92mm fan. Well, they have one, but it's not for retail and only comes packaged with the NH-U9F heatsink in tow.

Tomson · Post by **Tomson** » Wed Jan 02, 2008 3:29 pm

I was actually talking about Noctua NF-S12-800 120mm fan, which do sell retail, didn't check the link, sorry.

I have the mentioned 92mm fan with noctua heatsink, so if 92mm is so silent, 120mm should be dead silent.

I'd try a 120mm PWM fan like the Artic Cooling as they can be set to run very slowly at low loads and yet ramp up if the CPU is heavily loaded. This gives you both quietness and flexibility.

I use one of these fans with my SI-128/E4300 and when undervolted @ stock speed, the fan always runs at ~400rpm. When I overvolt/overclock for heavy processing, the fan will ramp up according to the CPU temp up to 1500rpm (I had to fiddle with my motherboard fan control settings to optimise this).

hi,

The Noctua NF-S12-800 120mm fan is truly the best fan for this 120 Ultra
If you don't OC just run it with with U.L.N.A. It's really the most quiet 120 mm fan I have heard so far !

I have heard that Noctua will also launch a 92 mm fan for the retailmarket by the end of this month ! I believe it will be a smaller version of the NF-P12 which has a more more effective airflow !

I cannot agree with the old noctua fans being best for the TRUE, because of tight fin spacing... I switched from a noctua to nexus 120mm on mine, and at the same fan rpm cpu temps was lower, with same ambient temp.

My whole P182 is outfitted with slipstreams (800rpms and 500rpms), one of them did click loudly for awhile, but the noise eventually went away (fan is still running fine)

You have excellent judgement of fan noise; the 800RPM Sflex is indeed quieter than the 800RPM SlipStream fan. However, the Slipstream, at 800RPM, pushes a great deal more air. At equal airflow, the SlipStream is the quieter fan. I know, I tested both on my equal-airflow fan fixture.
