The first Thermaltake ISGC series cooler we reviewed, ISGC-100, showed a poor performance. The ISGC-200, by its turn, brought a fairly good efficiency. Now, the ISGC-300 we review proved to be one of the best coolers we have tested so far. With the fan at full speed its performance is excellent, fighting with the best performance coolers we have reviewed, while keeping a good noise level. With low speed on the fan, it is almost inaudible, one of the quietest we have tested, keeping a very good cooling performance. It may not have the fanciest look, but does not look bad with its white fan.

The only flaw we found in this cooler is the fact that the cooler has no automatic fan speed control, nor a case-external fan control. But if you connect it to a fan controller, this problem is solved.

It is not a cheap cooler, but it is cheaper than similar performance coolers. So, Thermaltake ISGC-300 deserved the Hardware Secrets Golden Award seal.
