Thermaltake ISGC-100 (CLP0537)

The second new cooler we will be discussing today belongs to Thermaltake and is the junior solution in the ISGC lineup. This abbreviation stands for “Inspiration of Silent Gaming Cooling”. ISGC-100 ships in a small flat box with a girls holding a sword on the front if it, ready to defend the cooler (though it is not quite clear from whom):


The back of the box contains a brief list of cooler’s key features and the schematics of the airflow it creates. At the top of the package there is a small box with accessories bundle. Among them you will find retention kits for LGA775 and Socket AM2(+)/AM3, washers and screw-nuts, manual and warranty slip, and a 1 g pack of SilMORE thermal compound.

The cooler is surprisingly small: only 124x96x70 mm (including the heatpipes). And the heatsink itself fits completely under the 92x92x25 mm fan:


ISGC-100 is only 70 mm tall and weighs 335 g. despite its modest size, this cooler uses three copper heatpipes 6 mm in diameter that come out of the copper base in two directions and pierce the aluminum heatsink:

In fact, the heatsink is so small, that it seems there are too many heatpipes for it:


The heatsink consists of 37 aluminum plates. Each is 0.45 mm thick and the gap between them measures 2 mm:

The heatpipes are soldered to the copper base plate, which is a little less than 2 mm thick. The base surface is finished pretty well, it lacks just a bit to be as shiny as a mirror:

The base is also impeccably even:

Thermaltake ISGC-100 is equipped with a 92 mm nine-blade fan that is a smaller version of an ISGC 12 fan, which we have tested before:

It uses PWM-method to control its fan rotation speed in the interval from 600 to 1600 RPM creating 37 CFM maximum airflow and running as loud as 17 dBA. The claimed static pressure of this fan is 1.22 mmH2O. The fan uses a fluid dynamic bearing that should last for at least 50,000 hours. The maximum power consumption of this fan is only 1 W.

Thermaltake ISGC-100 is compatible with LGA775/1156 and Socket AM2(+)/AM3. Unfortunately, this cooler doesn’t support LGA1366 I was a little surprised that a small and lightweight cooler like that is installed onto LGA775/1156 using a screw-on retention that goes through the board. However, the explanation is evident: the cooler is so compact that it is simply impossible to use standard plastic push-pins on it. That is why Thermaltake engineers could only use mounting spindles and large screw nuts that are tightened at the bottom of the PCB. As for the AMD mainboards, the cooler is installed with a common swing-clip with a locking tab.

During cooler installation onto a Socket AM2 mainboard, it will block the first memory DIMM slot, no matter which way of the two possible ones you turn it (even if there is a memory modules without the heat-spreaders on it):

Also, this cooler didn’t fit at all on one of the LGA775 mainboards that I had at my disposal, because the cooler interfered with the chipset and MOSFET heatsinks:


Mainboards designed for HTPC systems, which are the primary target platform for Thermaltake ISGC-100, often don’t have any large heatsinks in the area around the processor socket that is why there shouldn’t be any problems like that there. And in our case, we used Albatron NF 650i Ultra for tests on an LGA775 platform.

No matter how shocking it may seem to you, but the MSRP of this little fellow is $49.99. What are they asking so much money for? It is really pleasing that according to Google product search you can now buy Thermaltake ISGC-100 cooler for $33, although even this price is way too high, in my opinion.
