[Archduke Tips]

If you aren't having an overheat issue then I wouldn't change your cooling setup. If your computer starts to reboot mysteriously or freeze frequently during video games then it might indicate overheating.

If you decide that you absolutely must cool your computer better, then here are a few recommendations:
1. Use a thermal paste between your CPU and heatsink with a high thermal conductivity.
2. Use a heatsink that is made of metal with a higher thermal conductivity (copper > aluminum) and look for one with lots of surface area (usually provided by fins). The surface area allows for more heat dissipation to the surrounding air.
3. Change the fan on the heatsink to one that has a higher volumetric flow rate.
4. Make sure that there is a good path for hot air to be removed from the CPU/heatsink and the video card. Any obstructions, such as wires, can reduce the effectiveness of your fans.
5. Add fans to increase the air flow rate... once again you should make sure that they are positioned properly so that they remove hot air from the case.

The heat travels in three paths... First from the component into its heat sink. Next from the heat sink into the air. Lastly from the air inside the case to outside the case. You want to make sure that the heat can move effectively through each path.
