Nothing about the GlacialTech IGLOO 5710 Series really stands out as a need to have item. The performance is relatively low when used with a high speed multi-core CPU, and when the heat is on the acoustic nuisance rises just as much as the processor temperatures.
With that being said, the 5710s only cost around 30 Dollars and for many this will be the only feature of concern. Many processors are sold as OEM or tray style without retail heatsinks and many home system builders look for OEM style solutions with OEM style price points. If completing your system at the lowest possible cost is what you are looking for then the two 5710 coolers will work fine for low wattage CPUs. Our testing configuration is geared more for high speed multi-core processors so the performance numbers tend to be a little high when compared to single or even dual-core processors in real world performance.
Product availability is where GlacialTech needs to improve the most. With a distributer now setup in the US and Canada this area will improve quickly as products start to roll in. The home OEM system builder depends on availability just as much as cost so getting the products in their hands is obviously important.
