Hot CPU
It's been record-breaking hot here in our part of the world.
As having the a/c on all day dries our throats out, we occasionally switch it off whereupon the living room temperature rises to 30º.
I keep an eye on my CPU temp (AMD Athlon 64x2 dual core, ducted air cooling from outside the PC) and it gets to around 50º, maybe 52º on one core, the other a few degrees less, under these conditions.
I've tried all manner of additional cooling systems, some of such stupendious primitive construction (taking blanking plates off front of PC and fitting a 12v fan to blow air into the case) that I won't reproduce photographs here. None had any effect.
Putting the a/c on gets thr room down to 26ºc and the CPU drops to around 48º max.
Pending the usual autumnal rebuild (and cleaning of cooling fins !) are these temperature differentials between ambient air and CPU temps. normal ?
