I did a quick search here, but didn't come up with anything. Has anyone had any experience with the Nexus D12SL-12PWM fan (120mm, PWM, open corner (yeah!)).

I have one in my Antec SOLO connected to a Thermalright HR-01 Plus, using the motherboard PWM control it is at ~ 700 RPM and I cannot hear it over the 2 front intake fans (Nexus 92mm Real Silent @ 70% via BIOS ~ 1200 RPM) and the Corsair HX450w PSU fan (which at normal load runs at the slowest speed).

If I put my ear close to it I can hear a soft "electronic" whine. (for lack of a better discription)

Keep it under 800 RPM and everything will be OK. It's getting really nasty above 1000 RPM. I'm using this fan only for my (rare) 'late night overclocking sessions'.

My current machine's Scythe Kama PWM 120mm fan normally runs under 700 RPM. So, I assume this Nexus will run similarly. Opening the corners of that Scythe Kama was a pain. So, I guess I'll give the Nexus a try. Thanks.

Xbit tested this with other 120mm fans:

and came to a similar conclusion as wojtek saying that it's noisy when much above 900RPM.

I've experimented with one as a CPU fan on a Thermalright HR-01; as I recall it's running under that magic speed, and being inside the case I don't find it objectionable. I found it too buzzy/clicky when I tried using it as a case fan.

I have one of those Nexus fans. It makes a slight clicking noise but I can only hear it with my ear close to it. I suppose there are quieter fans available but it's not bad. Plus, it's PWM and inexpensive.

I basically agree with what everyone else has said so far. It's a great, silent fan when the RPM's are turned down. If you are looking for real silence, I would not recommend getting this fan unless you have a PWM header that you will be hooking it up to, or a fan controller. I had to use this fan on a 3-pin header for a while, and spinning at 2000 RPM's it really does move a lot of air, but it's quite audible at these levels. I think this fan would be perfect for anyone looking for a nice PWM controlled fan, made by a great company, at a fair price.

I bought one and put it into the computer I just built for my wife as the CPU heatsink fank (Thermalright HR-01 Plus). On the PWM CPU Fan header in that Intel DP45SG, it normally runs at about 450 RPM. I can't hear it at all. I'm very happy with it.

Ah, very nice. I was thinking of using mine for a CPU fan on an HR-01 as well. Have you tried cranking up the CPU (maybe Prime95 or something similar) and seeing if the fan gets much louder/faster? I'd love to know :)

Well, I started up Prime95 (with the option selected for maximizing CPU heat) and HWMonitor and let it run for 15 minutes. For the last 5 minutes of that, all the temperatures had stabilized. Unfortunately (from the point of view of testing the fan), it couldn't heat up the CPU enough to rev up the fan. Here's a screen shot:

Basically, the CPU temperature went from 36 degrees C to 60 degrees C, the two case fans increased speed just a tad, and the CPU fan changed not at all. I never heard any difference from the computer.

From a personal point of view, I'm pleased as punch. But, that doesn't make a very good test. Here are the components of that system:

Case: Antec Solo
CPU: Intel E8400
CPU Heatsink: Thermalright HR-01 Plus
DVD Drive: Pioneer DVR-216DBK
Fan, Case, Front: Nexus DF1209SL-3
Fan, Case, Rear: Scythe SFF21E
Fan, CPU: Nexus D12SL-12 PWM
Hard Drive: Western Digital WD6401AALS
Memory: Kingston KVR1066D3N7K2/2G
Motherboard: Intel DP45SG
Operating System: Microsoft Windows 7 Ultimate (x64, RTM)
Power Supply: Nexus Value 430
Video Card: Gigabyte GV-N96TSL-512I

Well thanks for the info! I guess the heatsink and fan are doing their job well enough if the fan noise really doesn't increase. That's very good news :) I'm feeling even more favorable about the HR-01 now!
