GlacialTech Igloo 5750 Silent CPU Cooler Review

E4600 Temperature Testing

E4600 Maximum Idle Temperatures



With MX-2 TIM the Intel stock cooler does do a credible job of keeping this dual chip cool, but it was outclassed by the Igloo 5750. Even the Thermalright Ultima was only able to reduce its idle temperature one degree celcius further. This slight difference may be in part due to MX-2 vs. Stock TIM that was used on the 5750. However, the Igloo’s 5750 fan was more noticeable than the stock cooler which was idling at only 700+rpms. It should also be noted that due to the loads on the CPU being so minimal during idle, there was very little seperation between the different coolers we tested here.


E4600 Avgerage Load Temperature



This is where it gets interesting, and you can really see why spending extra dollars for an aftermarket cooler is worth it. Not only was the Intel Stock cooler completely outclassed by the Igloo 5750, but at higher loads and overclocks, it produces an incredible amount of noise. At an overclocked speed of 3.2GHz the stock cooler's fan was moving as fast as it could and was VERY noticeable above the other fans in the case. Whereas the Igloo’s 5750’s constant speed was just as “quiet” at 3.3GHz as it was when the system was idling. Please note that while the 5750 was quiet it was still noticeable above background fan noise. Overall, this is a good first result for the Igloo.

Testing was stopped at 3.5GHz due to the fact that my e4600 can only go that far with 1.4 volts.
