Re: Mac G5 Heatsink Upgrade Question
Generally, a fast CPU temperature rise indicates a ineffective heat transfer between the CPU and it's heat sink.
Just a guess, but the new thermal compound may not be making complete contact between the CPU/Heat sink (thus the fast temp rise) but be more effective at transferring the heat (and thus able to maintain the same maximum temp with less contact area). I'd check the CPU and heat sink for flatness.
