What's a good CPU Temperature
“CPU Temperatures”:http://www.pantherproducts.co.uk/Articles/CPU/CPU%20Temperatures.shtml. Now with Superfan,, I can see CPU temperatures, but what’s a good temperature to run?
Well, they vary by processor, but according to pantherproducts.co.uk, you should say 20 degrees C below the critical (e.g, above this I burn out) temperatures:
| Processor Family | Critical | Stay Below… |
| AMD Athlon “Barton” | 85C | 65C |
| Pentium III Slot 1 500-866MHz | 80C | 60C |
| Pentium II 450 MHz | 70C | 50C |
| Pentium IV | 80C | 60C |
For Pentium IVs, they feature a slow down function, so if temperature rises, the CPU actually slows down. But “Tech Republic”:http://techrepublic.com.com/5100-6270-5053843.html reports that developer data shows 80C.
As a point of interest, my current machines are:
| Motherboard | Processor | Idle Temp | Max Temp |
| ASUS p4v4x | Pentium III Slot 1 550MHz | 40C | 50C |
| Shuttle SS51G | Pentium IV 533FSB 2.4GHz | 39C | 50C |
| ASUS a7n8x-x | Athlon 2500+ | 41C | 47C |
