The heat sink is made of a machined copper base that interfaces with the CPU and a set of fins connected by 4 embedded heat-pipes.What�s interesting to me is that the heat pipes are only routed on one side; most cooler are symmetric in this regards.The copper base appeared to be machined-smooth and free of imperfections and comes with a protective plastic sleeve that we�ve come to expect with most coolers.

Installation of the Igloo 5750 was extremely straightforward, and it uses the stock AMD retention bracket which means you don�t have to remove the motherboard if you�re using it.To install the cooler, simply install the appropriate mounting bracket using 4 screws, then attach the cooler to the CPU using two more standoffs.I was a little disappointed that the standoffs didn�t have screws, so be careful that you don�t torque the screws too hard and damage the CPU itself.Finally, attach the fan cable to an appropriate port on the motherboard or power cable.

Overall, the installation process went very smooth, and there were no clearance issues between the cooler and other motherboard components such as the RAM and other capacitors at all.Once the computer was on, I was pleasantly surprised that the noise level was on-par with a typical 120mm CPU cooler; thanks to the lower fan speeds in this model, the cooler operates fairly quietly.Not the quietest air cooler on the market, but certainly respectable performance.No LED lights are installed on this cooler, so no light show.
Testing:
AMD 64+ 4000+ S939 Winchester
Biostar T-Force Motherboard
Corsair 1GB ValueSelect PC3200 DDR RAM
GeForce 7600GS
Western Digital 250 GB 7200 rpm harddrive
Idle temperatures were taken running Windows and full loads were taken while running SiSandra�s Burn-in Module.Temperatures (in degrees Celsius) were recorded, with the results compared with two recently reviewed air coolers: the Silentmaxx Frostbite CPU cooler and the Zalman CNPS9700.Ambient temp was about 20C.
Stock speed:
Results after overclocking to 2640 MHz-
Overclocked:
As you can see in both tests, the GlacialTech Igloo cooler didn�t have as great a performance as these other two but certainly has respectable performance.The difference between the coolers when the CPUs were overclocked is slightly higher, perhaps because the fan speed did not increase with temperature.
Conclusion:
The GlacialTech Igloo 5750 Silent CPU cooler is another example of a well-designed product that is easy to install and gets the job done as advertised.I was impressed by the double fan configuration that worked well yet didn�t produce a lot of noise.And the cooler is compatible with a wide range of CPUs.While I couldn�t find any pricing on this cooler online, I suspect it will be more affordable than some of the higher-end coolers, making it a good choice for a solid cooler that will blow away any stock cooler.
Pros:
+ Very easy installation
+ Decent cooling performance
+ Quiet operations
+ Small form factor with ample clearance around the cooler
Cons:
- Performance fades at higher temperatures
- Be careful when installing (no springs to prevent over-compression of CPU)
