Easy to install; quiet, variable-speed fan; good performance; competitively priced.
Bulky; can interfere with RAM cooling if installed facing upward.
Everyone and their CPU-cooler-manufacturing mother are jumping aboard the skyscraper-formfactor bandwagon, hoping to match the performance of
Thermalright’s Ultra-120 eXtreme
air coolers. Last month we tested
, and this month we have Thermaltake’s answer, the ISGC-300, one of a series of four ISGC-branded air coolers recently released into the wild. Thermaltake’s creative relationship with the English language is responsible for the ISGC moniker, which stands for “Inspiration of Silent Gaming Cooling.”
The ISGC-300 consists of a copper heat exchanger with four heat pipes running into a tower of 33 saw-toothed fins. At 6.24 inches high by five inches wide by 2.8 inches deep, it’s slightly shorter and narrower than Thermalright’s Ultra-120, but about a quarter-inch deeper. A 12cm white Thermaltake hydrodynamic-bearing fan is held onto the front using metal clips in a manner reminiscent of the Noctua NH-U12P. The nine-bladed fan is quiet and includes a variable-speed switch in lieu of a four-pin PVM connector. At its quietest, it’s nearly silent; at its loudest, it’s still damned quiet.
