To get back on topic...another "natural" tip for controlling computer heat is to clean out the dust in a PC. For laptops, just some compressed air through the vents should help.
For desktops, it's a little more complicated. To get all the dust out of a computer, you should wipe off dust on the case first, open it up, blow out dust in corners inside the case. Next is to blow dust out of the power supply fan. After that, the CPU fan might have some. Blow ye dust away shipmate!
Finally, a personal experience with this problem is your graphics card might have dust
inside itself. This can only mean one thing: open the GPU. Tech-savvy guys are necessary for this.
