| *Note: there are minor differences in measured SPL due to the variety of fan orientations and mounting methods offered by the compared coolers. |
The ETS-T40's middling performance with our reference fan puts it in the company of such heatsinks like the Scythe Ninja 3 and the Titan Fenrir; the latter is another direct-touch heatpipe model with a flawed mounting system that could use increased pressure.
MP3 SOUND RECORDINGS
These recordings were made with a high
resolution, lab quality, digital recording system inside SPCR's
own 11 dBA ambient anechoic chamber, then converted to LAME 128kbps
encoded MP3s. We've listened long and hard to ensure there is no audible degradation
from the original WAV files to these MP3s. They represent a quick snapshot of
what we heard during the review.
These recordings are intended to give you an idea of how the product sounds
in actual use — one meter is a reasonable typical distance between a computer
or computer component and your ear. The recording contains stretches of ambient
noise that you can use to judge the relative loudness of the subject. Be aware
that very quiet subjects may not be audible — if we couldn't hear it from
one meter, chances are we couldn't record it either!
The recording starts with 5~10 second segments of room ambiance, then the fan
at various levels. For the most realistic results, set the volume so that
the starting ambient level is just barely audible, then don't change the volume
setting again.
FINAL THOUGHTS
Ouyr first glimpse of the Enermax ETS-T40's solid mounting system made us think that this could be the direct-touch heatpipe cooler that finally takes down the venerable Cooler Master Hyper 212 Plus, the king of budget heatsinks. But like the Reeven Kelveros, Swiftech Polaris 120, and Titan Fenrir before it, the ETS-T40's mounting hardware doesn't provide good enough contact between its base and the CPU. The end result is middling performance, and it's only capable of that at high stock fan speed or more quietly when armed with a quality fan. The included Enermax Twister fan is a smooth sounding model that surprisingly delivers poor cooling proficiency at less than top speed with the ETS-T40. At comparable noise levels, our reference fan tromped it.
The ETS-T40 is yet another in a long line of flawed direct-touch heatpipe coolers with more bark than bite. High cost would make the ETS-T40 a complete blunder, but thankfully it has a very palatable street price of only US$35. But if you're into quiet cooling, we don't believe it's worth even that much, not if one has to replace the fan to achieve acceptable cooling performance. It could work cool and quiet enough if your CPU runs cooler than our hot i7-1366. The aforementioned Cooler Master Hyper 212 Plus can be found for a mere US$25 or less at some e-retailers, however, and unless this model has changed significantly from the sample we tested two years ago, it is tough to match.
Our thanks to Enermax for the ETS-T40 CPU cooler sample.
