Have been looking at the AMD Athlon 64 4000+ chips and im very tempted so im trying to get as much info on them.
Does anyone know how hot these get on average and if so can anyone recommend a cooling method other than water cooling.
Cheers.
At a average on air cooling, your looking at about 30C-35C on Idle, and under 45C on Load (varies on cooling type, motherbooard choice and environmental changes)!
As for the cooling advice, check out This thread 
The Arctic Freezer coolers are very good and will definately cool that CPU well enough. http://www.arctic-cooling.com/cpu2.php?idx=10&disc=
Great stuff cheers!
And now the Freezer Pro series is out, quieter, cooler and supposedly all round better cooling!
