The GeminII M4 poses no threat to the Big Shuriken 2, generating CPU temperatures 13~16°C higher at similar noise levels. It's not even a match for the now discontinued original Big Shuriken and only edges out the waifish Scythe Kozuti by a few degrees.

The GeminII M4's VRM cooling is just as poor though it did improve substantially when paired with our thicker reference Nexus fan.

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.
