Manufacturer	GlacialTech
Model	Igloo 5750 Silent & PWM
Price	$??
Category	Entry Level

GlacialTech launched the latest IGLOO 5750 PWM CPU cooler and IGLOO 5750 Silent CPU Cooler for both Intel LGA775 Socket CPU’s and AMD 754, 939, 940, AM2 & F Socket CPU’s. The unique design for the enthusiast incorporates a specially aligned aluminum heatpipe combination of four pipes that dissipate the heat from the CPU directly into the heatsink fins.

The low decibel (19dB), high volume (30.8 CFM) fans are 92mmx92mmx25mm and run at an ultra-quiet speed of 1800 RPM. The dual fan is a unique concept that not only cools down the radiator, but the added blow down effect also cools down the heatsink directly above the CPU.

Unlike the Silent version of this series, the PWM version has a dual 92mm×92mm×25mm adjustable speed fan setup which brings the temperature down according to your needs. The fan ranges in speed from 800~2500RPM, with a maximum volume throughput of 51.3CFM. The Fan puts out 34dB maximum at full revolutions. The entire heatsink (both versions) keeps a relatively low profile and only weighs in at 507grams, making it safe and light enough to pose no danger to your Intel CPU (Designed to comply with weight regulations of 550 grams on Intel CPU’s).

- Retail package

The medium-sized packages of GlacialTech Igloo 5750 Silent & PWM have a plastic window on the front.

The GlacialTech Igloo 5750 series include two 92mm fans that should give pretty good performance.

The bottom isn't something special, it uses Intel's standard mounting mechanism, that should also mean an installation process.

Four U-shaped aluminum heatpipes transfer all the produced heat to the aluminum fins...

- Installation

The installation process is very simple, no worries here. We didn't encounter any major problem with the GlacialTech Igloo 5750 series, despite the presence of the big heatpipes.
