How thick is your cold plate? also, does your waterblock get hot to the touch(especially the base of the waterblock, is it hot feeling?)? your problem could be one of three things (i have the same issue with a 120w pelt on a duron 650, around 60-75F temps)
1. Your cold plate sucks
2. Your cold plate sucks
3. Your waterblock sucks
1 and 2 are most likely, and what i know for a fact is my bottleneck, you see, with the Duron chips, you have a teensy tiny core to radiate all that heat, so your coldplate needs to be extremely effective, i have a brass/bronze one now that's like 2.5mm thick and while it was fine on a nice big fat slug'd celeron 366 on a duron it just can't cut it. I'm looking for a source for a pure silver cold plate, something like 45x45x8mm
and yes, i have tried two waterblocks, both of which i know to be extremely high performers, with only a 4F change in temp
www.anime-unlimited.com/tomservo <- the aluminum block is what i was using, now using the copper block of which i have no pic of the inside
PS: Kevin, do you buy painted heatsinks too? cause i can't think why anyone in their right mind would buy a painted radiator for a high performance application. Paint isn't very heat conductive as opposed to raw metal.
