I get quite a few coolers to test that pass over my desk. Most of these coolers follow the basic tower design and heatpipes of various quantities and diameters that remove the heat either by directly touching the IHS of the CPU, or removing it from an aluminum or copper base. What soon follows after the design is to start looking at a sufficient cooling mechanism or a high CFM fan in most instances. We should all know by now that with high CFM fans brings with them an elevated noise level as well.

Thermaltake is one of the smaller percentages of manufacturers that are taking the jump to silent computing. They have developed a line of ISGC, or Inspiration of Silent Gaming Cooling CPU coolers. Thermaltake incorporates a new fan to cool this line-up of coolers, the Pure Silence ISGC Fan 12. This fan provides a decent amount of CFM and has some technology involved to keep the noise levels down to a whisper while in use. More on these fans will be discussed later in this review.
