Performance

Test system:

Note:
Idle refers to the computer sitting at desktop for 30 minutes.
Load refers to the CPU running 100% on both cores via Intel’s Thermal Analysis Tool (TAT) for 15 minutes.


At stock clocks, when idling, the Igloo 5750 performs on par with all other coolers. Yet, under load temperatures, the Igloo 5750 runs warmer than all other coolers, but matches the performance of the Intel stock cooler.


Once overclocked, the Igloo 5750 again runs slightly cooler than the Intel stock cooler when idling. But again, under load temperatures, the Igloo 5750 runs warmer than all other coolers and even 5°C over the stock cooler.

Noise:

The Glacialtech Igloo 5750 Silent holds to its name and is totally silent. It is not audible at all over standard case fans once the case is closed. This silence remains at all temperatures, whether idling or at load. The Intel stock cooler is marginally louder at stock, but a lot louder when under load or when overclocked. The Igloo 5750 is noticeably a lot quieter than the Intel stock cooler when running at higher speeds.
