Well, I live in England so that's pretty impossible. But I do keep the heating off in the room where my PC is, it's usually about 5 degrees.
I just tested it with RealTemp, here are the temperatures. At the time of testing I had this webpage, TeamSpeak 3, a small fps game called Sauerbraten, and Steam open.
Are these decent? And if not, what can I do to make them better?
My CPU is an Intel i5 3570K (non-overclocked), and I have four case fans and a Xigmatek Apache heatsink. I suppose I could try to mount an extra fan if it would help.
