I've measured the Noctua's airflow at 12V to be ~49 CFM. If you really need that much airflow, then you might consider one of the Scythe sleeve-bearing fans. They probably won't have the durability of the Noctua, but they don't vibrate so much and have an excellent noise:CFM ratio. Alternatively, th...

I have both of those fans. The Gentle Typhoon is better IMO. They are both very quiet, quality fans. My observation is that the Noctua has some vibration problems. In free air, it's just as quiet if not quieter than the Gentle Typhoon... that is until you attach it to something. Then the vibration o...

The FDB Kama series is probably a better bet for cooling a video card. They stand up to heat better. Nevertheless, the PWM Slipstream is very good for a sleeve-bearing fan. I don't have a Kama on hand, but I do have various other Sony FDB fans for comparison. They are usually consistently good, exce...

Thanks for the insights, Mike. I think I'll try anyway since--as you said--most people want/expect to see CFM. I wonder if perhaps turbulence might have been throwing off the readings on your last fan test platform. What I've read about HVAC is that you're supposed to take the FPM readings away from...

Fan Testing Equipment
I'd like to purchase some equipment to test fans. I already purchased a B&K SLM, but I'd also like to measure CFM and possibly static/differential pressure. Here are the two candidates for anemometers: Kanomax 6813 w/AP275... this is pretty much the same as the 6803 that SPCR uses. I'm also consider...

Some boards (such as my Gigabyte DS3) increase voltage beyond normal operating specs when the CPU and/or FSB is overclocked. The stock vcore for a Core 2 Duo is anywhere between 1.25 and 1.35 volts. So the reason your temperature is higher even at OC speed is because: 1. You are running below stock ...

I wonder if having such a large side intake is really a good idea. The problem is that it totally annihilates the normal flow of air required to cool *all* components of a system. Sure, it will cool the motherboard, cpu, and video card, but what about the hard drives sitting in the front? I imagine ...

You could always try undervolting:
viewtopic.php?t=35532
If you run at 1.025v your CPU's TDP will be just 35W max. At that output, even the stock HSF won't have to spin up

It looks like Scythe has discontinued the DF series of fans and replaced them with NMB/Minebea fans: http://www.scythe-usa.com/product/acc_top.html This is unfortunate, the NMB/Minebea are--by most accounts--acoustically inferior :( I wonder why they did this. They must have got an outstanding deal ...

Sorry for letting this thread sit idle. I don't like to report my readings until I'm sure they are 100% stable, but I haven't been able to do the full gamut of tests because I've been busy. Also, I was having trouble maintaining stability at totally stock settings (i.e. defaults) at low voltage. So ...

Stock & SuperPi results added. It looks like the overclocked/undervolted settings at 3.0 GHz/1.25v make it run at the same power efficiency as stock at 2.4 GHz/1.325v, except for idle power using EIST. For example, at 2.4/1.325v with EIST disabled, power consumption was 128W compared to 3.0/1.25v at...
