I have an athlon mobile 2600+ overclocked to 217x11.5 (about 2.5Ghz), with an ALX-800 and Panaflo U1A. I've noticed reading through a lot of other threads that in general idle and load temperatures might only differ by about 5C. However monitoring my temps with MBM5, I've noticed that when not doing anything at all, the temp can drop to 38C or lower, when using the computer to surf the web, download, listen to MP3's it might rise to about 44C, and I remember seeing 49C when running prime95. Is this normal?
