The Samuel 17, aided by our reference 120 mm fan, rises to a position near the top of our charts, edging out the Big Shuriken paired with its 12 mm thick stock fan. The difference is particularly notable at the 13 dBA level where the Samuel 17 takes a 6°C.

The Slim Silence, being so much smaller than the rest of the field sits comfortably in last place, 10°C back of the most recent Phenom II AM3 stock heatpipe cooler. Though it seems like a disastrous result, it is rather impressive given the Slim Silence is less than half the height of all the heatsinks compared above.

The tables turn when both the Big Shuriken and Samuel 17 are equipped with our reference 120 mm fan. Scythe's heatsink edges out Prolimatech's by 3°C, both at 12V/16 dBA and 7V/12 dBA, so the Big Shuriken retains remains the top dog when it comes to compact coolers.

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.
