The heatpipes are slightly flattened at the base and soldered to the copper plate, which is a little over 2 mm thick:

The base finish quality is quite superb:

Even though the base is a little bent, the thermal compound imprint from the processor heat-spreader turned out quite decent:

Thermaltake ISGC-300 is equipped with a nine-blade 120 mm fan from the same series: ISGC 12:


We have already tested this fan in our massive fan roundup that is why here I would only like to remind you that its rotation speed can be adjusted in the interval between 800 and 1300 RPM using a small inconvenient regulator attached right to the short fan cable:

Despite numerous criticism of this device, Thermaltake continues to use it for their cooling systems and fans in particular.

ISGC-300 is compatible with Socket AM2(+)/AM3 and LGA775/1366 mainboards. The cooler installs on any of these platforms using steel retention brackets and large screw-nuts with washers that need to be tightened at the bottom of the PCB.

Socket AM2(+)/AM3



For AMD platforms you should use a special backplate.

When the cooler is installed onto the CPU, the distance between the lowest heatsink plate and the mainboard surface is 51 mm that is why it shouldn’t interfere with the electronic components around d the CPU socket or tall memory heat-spreaders:


There is no mention anywhere in the manual about the preferable installation position for Thermaltake ISGC-300 cooler. During our tests we didn’t reveal any serious difference between the two possible installation positions that is why we performed all our tests with the cooler turned in such a way that the airflow could be directed towards the back of the system case:

You can download the installation instructions from the official web-site (PDF file, 743 KB). The recommended retail price for Thermaltake ISGC-300 is set at $59.99.
