Mine sucks, I could use some low budget suggestions?

Basically I have 2 front fans, 2 side fans, a blowhole fan, and an exhaust fan. I only use the side fans for days like the summer when it is really hot in the house or I am gaming (or both combined), with my fans full blast it sounds like an airplane but it keeps my PC at about 45/47C, maybe 50 dependong on how hot it is here in california. On a winter day, I can take my two side fans off and itll stay about 42C. I wish they werent so low but it seems to get so hot. My CPU fan kind of sucks too. well, its alright. I just need to upgrade my computer blah.
