The smallest heatsink in our roundup, the Silverstone NT07-775, is also the worst. Compared to two other two miniature coolers, the Q9550 stock heatsink and the Thermolab Nano Silencer, it came in last. When each cooler's fan was set to generate 17~18 dBA, the NT07-775 lost by a significant 8°C. At 15 dBA, the difference lessened somewhat to 5°C. However the NT07-775 is in a league of its own due to its extremly slim profile — if you consider its application, none of the heatsinks we've tested are fair competitors.

The harsh sounding fans equipped on Intel stock coolers may tempt users to dial down the fan speed to tolerable levels, but unfortunately doing so pays a steep thermal price. Replacing the fan with a 120 mm Nexus results in much improvement. At 12V/16 dBA the Nexus fan cooled the CPU 9°C better compared to the same heatsink with the stock fan speed lowered to an equivalent measured noise level (though the Nexus actually sounds a lot better). At 9V and 13 dBA, it posted a 5°C improvement over a standard all-aluminum Intel stock heatsink running at 6V at the same SPL. While not the most elegant solution, it certainly is worth consideration if your cooling needs are not great.

The Alpine 7 Pro performs more or less the same as the Intel stock coolers when their respective fans at generating sound levels above 20 dBA@1m. At quieter levels, the Alpine is far superior, boasting 4°C and 1 dBA advantage at 7V compared to the Intel all-aluminum cooler at 9V. At the 12 dBA level, it delivered a 10°C improvement over the Intel/Nexus combination The wide fin spacing makes the Alpine an ideal low airflow cooler as long as it is used with a modest processor.
