I had a laptop that consistently ran too hot before (it was running hotter than yours, though, about 70 degrees Celsius).

Nothing I did really helped it, but killing processes that don't need to be running is probably your best bet.

If it's not a laptop and you can actually get into it, you might want to consider buying more or better fans or getting a better heat sink. You may also be able to get some software that lets you manually control the fans or set them to come on at lower temperatures.

You could also try doing a clean install of Windows. Never hurts to do that once in a while and it pretty much eliminates any software related issues.
