The Thermaltake ISGC-300 CPU Cooler

(Click the above image for the large version)

Removed from the inner package, the ISGC-300 comes with the ISGC Fan 12 already clipped to the cooler. You can see here that with only 33 fins, the 120mm fan gets excellent coverage of those fins.

Turning the cooler to review its profile shows those 33 fins with their ends bent to support each other. You can also see just how much the 120mm fan stands proud of the fins both above and below. Something else that stands out here is how Thermatake uses black caps to cover where the heatpipes protrude the top of the cooler.

This angle provides a look at a couple of things I'd like to point out. First is the Sawtooth design of the fins. Both sides are shaped like this, as you will see a bit later. Second is that Thermaltake uses a slightly staggered offset to the heatpipes to try and maximize the airflow through them.

Removing the fan and laying the ISGC-300 down, you can see the Sawtooth design is carried out on both sides. Thermaltake has also built this cooler to allow for two fans in a push/pull configuration. The only issue I see is the cooler nor the ISGC Fan 12's come with any extra wire fan clips. This may have just been an oversight as this is still not on the market yet.

Just to take a step back and see the ISGC-300 without the fan and to give yet another perspective of the large black heatpipe caps.

Close to the business end is the heatpipes. As you can see, Thermaltake makes very gentle bends to these 6mm pipes that seem to be clamped into the base. This makes the heatpipes a bit more oval and actually should add to the foot print that can absorb heat.

And here we have the money shot! The base is copper and level, but as you can see there are slight imperfections in the base. This is way more visible in the camera image than with the eye. Under normal observation, the base has a mirror like finish.

Here is a closer look into the ISGC Fan 12, 120mm, 58.3 CFM, Pure Silence fan. As you can see, the flower like fan blade shape is no exaggeration, it does look like a daisy when not in motion. This combined with the relief notches cut in the tips of each blade aid in drastically reducing overall fan noise levels.

I just wanted to display the part number for those looking to grab a ISGC Fan 12 at a later date, as well as to allow you to see the usage requirements of the fan. Notice at the bottom right of the image, this fan has two leads running off it.

Those two leads end in a 3-pin motherboard power header, and the other with a detachable clip is the variable speed controller that allows you to fine tune noise versus performance.
