CPU Temperature

My CPU temp is reading between 55dC and 58dC on Idle. I know the temp will go up when useing applications heavily. That makes me concerned about the idle temp.

I run lots of 3D games, Paint Shop Pro, and AutoCAD. If I'm running these apps, I'm afraid I might be overheating the CPU. I've noticed some random freezes, but after a reboot, the temp is at the tidle temp. So I don't that's the cause of the freezes.

I didn't build the computer, I bought it pre-built. I've only had it a couple of days, so I'd just like to make sure the computer is safe for longivity.

My NEW Antec power supply is 350W and has the standard fan in the back, and an additional fan aimed into the case. There is no other fans into or out of the case. I have, what looks like (a circle shape of holes under the PS), room for a case fan on the back of the case, but no room for a side case fan.

Would I need a new case with fans to lower my temp?
