Still warm from our most recent PCI Express Scaling comparison, EVGA’s P55 SLI was retained for the “just right” overclock settings that were already programmed into it. We wanted to approach (but never reach) the processor’s thermal limit and these settings worked perfectly for nine of the 10 coolers.
Several coolers hung over the memory slots of our motherboard, preventing the use of memory with tall heat spreaders. We skipped the heat spreader issue entirely by using Crucial DDR3-1333 modules, yet were still able to use DDR3-1600 settings.

Priced at around $150, Galaxy’s CM-140 has gotten a great deal of attention on the Web as one of the broadest-range, most accurate SPL meters available for under $400. We love a great deal!
Taking a cue from the audio world, we wanted to gauge all of today’s performance coolers at a distance of one meter. The problem for us is that the bottom of our SPL scale is 30db, and the meter is only accuracy rated for decibel levels of 32db or higher. In order to get a “higher” reading from quieter parts, we measured each cooler at 0.25m and then used one of several SPL conversion applications to convert our readings to one meter.
However, the method isn’t perfect--testing several items of known SPL values revealed a consistent 1db (lower) difference that might be attributable to improper meter calibration. To compensate, we added 1db to all of our measurements.
