50C is not a problem at all, neither is 55C. You asked "Why is my PC so hot" but 55C is not "so hot" at all. However, if you want to cool your computer, don't buy things that are a waste of money like liquid cooling, tons of fans, or thermal greese.

Read the column I posted about how to REALLY cool your PC.
