Sibak AT01515B TwinHead Heatsink Review
Sibak AT01515B TwinHead Heatsink Review
  69%   
Abstract: While we didn't fly around the world just to look at heatsinks, we have had the opportunity to look at several of their coolers, the first of which is the AT01515B "twinhead."

Acoustic Samples: Listen to this Heatsink!

With two fans spinning at around 4500RPM the Sibak AT01515B is noisier than you might initially expect for a heatsink with 50mm fans. The key here is fans, with two motors there is bound to be an increase in noise levels.

To hear for yourself what this heatsink actually sounds like, just click on the headphones and listen to the MP3 recording.

Sound Level Measurements:

Listening to the actual noise a heatsink makes allows you to hear what pure numbers alone cannot get across. To further emphasize FrostyTech's reliance on cold hard facts when evaluating a heatsink, we also take Decibel readings with a sound level meter. The list of heatsinks which have had their noise level measured continues to grow as more are tested.

FrostyTech Sound Level Results
- Manufacturer Model Noise Level Scale
Zalman All Flower HSF 47.4/28.9 dB quiet
Noisecontrol Silverado 50.8 dB
Thermal Integration Ti-V77L 53.0 dB
Tocools Crown 54.5 dB
Sibak AT01515B 55.8 dB
Dynatron DC1206BMP 65.1 dB louder

The Sibak cooler comes in pretty much in the middle of the road, but on the noisier side. While one or two degrees in temperature mean a lot, the human ear has a hard time distinguishing between sounds with less than 3 dB difference. Keep that in mind when you look at the above sound level measurements. The 38mm Delta fan on the Dynatron heatsink is substantially louder than everything else.

Synthetic Temperature Test Results: *Ranked according to 100W small interface die test results.

Ouch! Believe it or not there is one good number for the Sibak AT01515B and that is 60.1 degrees on the 100Watt test with the large interface die. Every other test is really pretty poor, or just not worth the bother.

The Sibak is really limited in terms of what processors you can realistically use with it, and given the somewhat noisy characteristics you might be well advised to just pass it up and try something with a little more kick.

Well the final results, which are the rise above ambient temperature results point to just one area of usefulness for the Sibak AT01515B. Coupled with the large interface die and a 100W heat load it seems to produce relatively good OEM results. Bear in mind that when I say "relative" I mean against its not that great ranking.

The small interface die doesn't seem to be able to spread the heat quickly enough to really take advantage of the design of the Sibak AT01515B and consequently the temperatures here are rather high.

Given what we heard, and what we see thermally you are best served by looking to one of Sibak's other heatsinks for good cooling. The twinhead design is cool to look at, but eye candy doesn't always work as well as it really ought to.
