Bench Testing with Noctua NH-D14

post #1 of 2
Thread Starter 
OK. I'm calibrating before I start formal testing. Thought I'd introduce my Tesbed rig. It's the Gigabyte wonderboard GA-P55A-UD3P that had me up to BCLK=232MHz oncet, along with my trusty i7 860 and 8GB Ripjaws-2000. I have the cpu running at 4004 MHz and the RAM at 1820. With an inexpensive digital thermometer (if it doesn't read true you buy another; this one's fine) and a digital sound pressure level meter.

I've discovered how to get OCCT to output CSV files, so I can take a mean of the "up" CPU1 temps, and subtract the mean ambient temp (the thermometer software averages it) to get a net temperature over ambient.

I'm still calibrating, but here it is:

Home made testbed, with a Gigabyte P55A-UD3P and a Noctua NH-D14. Current fans: Gentle Typhoon AP-14 push and a Thermalright TY-140 in the center. There is a digital thermometer under the motherboard near the fan intake. The PSU is an Antec 750W True Power New Blue (made by Seasonic), supported by plastic feet. The fans are connected to Molex directly from the PSU. The adapters are from Scythe fans. You can see the single wires that carry the RPM signals from the fans to the motherboard.

The Digital Sound Level Meter is a Tenma 72-942, set at 10cm from the center fan. By subtracting 20 dB from the measured sound pressure level, we have an SPL reading equivalent to 1 meter.

The basement is actually dead quiet with the furnace off, with less than 10 dBA ambient noise.

Gentle Typhoon AP-14 at work. The Tenma consistently reads 42 to 42.5 dBA for this setup. The stock P12/P14 produced an SPL of 47.5 dBA, so this set of fans is quieter than stock. You can hardly hear it.

Nice shot of the thermometer's business end.

You can see the Scythe adapters. I have enough connected to mb headers to read rpm's on three fans on the heatsink and another just to check the rpm's of fans not connected with the testing.

Passively cooled video card. It was cheap.

The psu and its glow. It exhausts air out the other way. You can also see the Kingston SSD and the old PATA DVD player. I didn't see the need to buy a new one for this job.

Side view. You can see the SPL meter on the far side.

You can also see how I butchered the TY-140 to adapt it for Noctua pegs for the fan clips. I have a much more elegant method now.

I used to have the digital USB thermometer next to the other two thermometers. The three showed a consistent difference, so I figured the USB therm was OK to use for testing. Consistency is what matters. So now I have it up by the fan. We'll see.

Oh yes: See that drill? It's a 9/32-inch drill. Hold it in your hand and partially drill out the fan screw holes until the fan clip pegs protrude far enough that you can use the clips. How far will depend on the thickness of a fan's flange.

Still calibrating.

Ooooh that thermometer was badly placed. It got up to 26+ centigrade. Oops. The air isn't that warm. Must be due to the cpu generating heat down there. So I put it out in front - 30cm in front of the intake fan, 20cm above the bench top:

Oops. Now it's reading 19.5c. What's wrong with that? The other digital is also reading 19.5c, and the USB should read 0.8c higher. The air flowing by must be cooling it. So, back to its sheltered spot:

Nice steady temps here.

OK. Calibration done.
