GlacialTech launched its latest IGLOO 5610 PWM CPU cooler and IGLOO 5610 Silent CPU Cooler for Intel CPUs on October 22 2007. The design and price aims at the entry level users who wish an affordable and at the same time efficient cpu cooler. The unique design incorporates a specially aligned aluminum heatpipe combination of two pipes that dissipate the heat from the CPU directly to the heatsink fins. From there, the Silent version’s fan brings the temperature down. The low decibel (19dB), high volume (30.8 CFM) fan is 80mm×80mm×25mm and runs at the ultra-quiet speed of 1800 RPM.

Unlike the Silent version of this series, the PWM version has an 80mm×80mm×25mm adjustable speed fan which brings the temperature down according to your needs, The fan's speed ranges from 800 to 3200 RPM, with a maximum volume throughput of 51.3CFM. The fan produces a maximum of 34dB  at full speed. The entire heatsink (both versions) keeps a relatively low profile and  weighs 373grams.

Highlighted Features

　● Quality Aluminum design with Copper base
　● Heatpipe-fin-airflow combination with Patented Engineering principles
　● PWM version: Enhanced speed adjustable Fan (800-3200 RPM)
　● Silent version: Silent performance (19dB)

- Retail package

The retail package of GlacialTech Igloo 5610 Silent/PWM versions are very simple. Actually both models are the same concerning the design and the physical structure, the only difference is the power management functions (PWM) of the 5610PWM model.

Opening the package, there is only the backpanel braket and a quick installation guide

The Igloo 5610 is fully made of aluminum with four (4) heatpipes and the 80mm fan produces low noise, according to GlacialTech. At the bottom there is already pre-applied thermal paste.

- Installation

The GlacialTech Igloo 5610 Silent/PWM function takes sometime to install it. The backpanel has a sticker that if removed will hold it until you secure all  the mounting screws. The whole process is rather simple and users shouldn't encounter any problem.

Due to its small volume, there shouldn't be any kind of problems, even with specially designed  motherboards. Finally here is how our CPU cooler looks after the installation on  Thermaltake's Soprano case.
