Glacialtech Igloo 5750 ~ Dual 92mm Fan Action

Glacialtech Igloo 5750

Glacialtech is a newcomer at the site, we have not tested any of their products yet, they have been around for a few years now, slowly emerging from the OEM market into retail.

GlacialTech Inc. was established in June 2001 by a team of 8 world-class researchers (PHDs) and three factory owners. Its technological areas of expertise include specialized thermal theory, soldering and mounting technologies, mechanism design, test and verification environment build-up and advanced conduct material development.

As a total thermal solution provider, GlacialTech is committed to using lighter weight materials, lower noise and lower manufacturing cost to deliver superior cooling solutions. All this has brought about the increased value for our customers with lighter system board loading, quiet working environment and optimal price performance. Price performance, noise performance and weight performance are our three cooling design philosophy. Having acquired ISO 9001 and 14001, GlacialTech commits itself to using green materials for its products designs and to perfecting green manufacturing processes in manufacturing its products.

GlacialTech offers two kinds of standard and customized cooling solutions. The standard cooling solutions deal with the CPU coolers for desktop and server PC system, PC case fan, VGA coolers and other accessory cooling products. The customized cooling solutions are furnished with applications for specialized PC barebones system, notebook, consumer products and telecommunication products.

The Igloo 5750 is a top down heatsink equipped with two 92mm fans which are set up in a push-pull fashion. An overall compact heatsink which weighs in slightly over half a kilo.

The make up of the heatsink is efficient and based on familiar combination of aluminum fins, copper base and heat pipes. The Igloo 5750 features four of them joined in the based.

The 92mm fans (CHB9212ABS) use are rated at ~1400rpm our RPM meter clocked them at 1250rpm at 12v.

Installation is pretty straight forward once you have screwed the correct mounting bracket on the heatsink, for Intel it’s tool less push pins. The copper base can do with a better lapping if you want to get the most out of the HSF, machine lapping marks are quite pronounced.

Motherboard compatibility shouldn’t be a problem with the Igloo 5750, it doesn’t come near memory slots or northbridge heatsink. The ideal orientation of the heat pipes is horizontal; this also leaves the most room around the more crowded areas of the CPU socket.

For performance tests we included the Intel Stock AL and CU, as well as the Scythe ANDY which is a top-down cooler with a single 1x120mm fan.

The 92mm fans on the Igloo 5750 can be undervolted, but at 5v their rotation speed dropped to only ~425rpm, which was insufficient to properly cool the overclocked CPU.

The outcome is a lot more positive than expected, with two 92mm fans at ~1250rpm the noise generated is quite acceptable at only ~41dBA. And as it turns out, performance/noise wise, this heatsink does quite well, beating the ANDY slightly, it’s definitely better than any of the Intel Stock heatsinks.

In summary here are the strong/weak points of the Glacialtech Igloo 5750 heatsink:

+ Compact size
+ Good performance/noise balance
+ Competitive pricing
+ Easy installation

- Base finish needs manual lapping
