my 2000+ AIUGA is cooled by a stock 2500+ heatsink + 70mm fan forced on the heatsink. it's in a case with one intake, one outtake and dual fan in the PSU
all fans work at 5V. this is very silent but heat is a major issue, my CPU is idle near 70°. the CPU is now downlocked to 1000mhz, and it's idling near 50° now. before, the top of the case and the PSU felt hot. now they're warm but it's not so bad anymore. the CPU dissipates at stock 60W, at 1Ghz about 35W.
I want to reduce the CPU voltage a bit because that's the real heat problem, and not the clockspeed nor the CPU heatsink (minimal airflow in the case)
the mainboard is an asus A7V600, unfortunately it doesn't support undervolting the CPU. what would be the best way to lower the CPU voltage, and what voltage would be optimal?

Hmmm, maybe you could replace it with a duron appaloosa, they're very cheap and work at 1.5v.

can't you connect certain bridges to change voltage ? I know you can up voltage that way, so lower will also be an option I think

yeah I can, but the conductive paint I've got doesn't work well
I might wiretrick it, how risky is it actually?
anyway, what voltage do you guys recommend?
I'm not going to take this PC more then once apart

I'd check your temp reporting first. 'cause 35W is nothing; and should not present the temp you are seeing. I remember my 1.1 Ghz Celeron at ~30 Watts (similar die to AXP) without case fan never exceeded 40C. Put an external probe and see what it shows.
