Prime95 keeps more sections of your CPU continually busy than most other software, DC or not, does.

For example, CPUs normally power-down the floating-point arithmetic unit when it's not in use (because most software doesn't routinely perform FP arithmetic all the time). But Prime95 keeps the FPU continually busy, so the FPU never cools off as it would when most other software is running.
Ah, I see now. Thanks!

Oh, and I'm assuming that LLR does the same thing that Prime95 does with the FPU, right? I would think so, since I've heard elsewhere that both Prime95 and LLR use your CPU to the fullest.
