Thermaltake ISGC-400 CPU Cooler Review



The tests for the Thermaltake ISGC-400 are twofold. First, I will test the temperatures while at stock, and the second set will be overclocked to 3.8GHz (205x18.5) at 1.5 volts. During testing, the computer will be left to sit idle for 30 minutes and the temperature will be recorded. Then I will run Prime95 for 30 minutes and again take the temperature. To monitor the temperature, I will be using AMD Overdrive's system monitor, as well as CoreTemp .99 to make sure the temperatures are accurate. All testing will be done in a Thermaltake V9 gaming case to show a real world environment for users, not an open system. The ambient room temperature will be kept at 24 degrees Celsius to ensure correct readings throughout the testing.

Testing System:

  • Processor: AMD Phenom II X4 955
  • Motherboard: ASUS M4A79T Deluxe
  • Memory: Mushkin HP3-12800 2x2 GB 9-9-9-24
  • Video Card : NVIDIA GTX 260 (216)
  • Power Supply: Mushkin 800w Modular Power Supply
  • Hard Drive: 1 x Seagate 7200.11 750GB SATA w/32MB Cache
  • Optical Drive: LG 8x DVD+/-RW
  • Case: Thermaltake V9 Gaming Case
  • Thermal Paste: Arctic Silver 5
  • OS: Windows Vista Ultimate Edition
  • Ambient Temp: 24 C (75F)


Comparison Coolers:

  • Thermaltake ISGC-300 (high and low fan speeds)
  • Stock AMD Heatsink
  • Titan Cool Idol
  • CoolIT Domino A.L.C. (on medium speed)










For the stock tests, the ISGC-400 ran a bit hotter than the ISGC-300, but still better than the stock AMD heatsink. Overclocked, the ISGC-400 showed a bit more improvement when idle, but was passed up by its partner, the ISGC-300. When overclocked, the stock AMD heatsink could not handle the thermal load.
