I find the same as you. My jasper is brand new 28/4/2009 and at start up the gpu is around 10C higher than the cpu then stabilising to 20C above the cpu after a while. Still stock at the moment but I want to look at firmware/software modding to keep it under control, like the xbox1.
It had nidec fans but I swapped them for some new deltas that I had set aside. Slight more noise but better imho.
Falcon with 9v mod runs cooler all round.
Wish I could find more info on editing xbr to permanently increase fan speeds or the monitoring of them. I am guessing this will come in time in homebrew. I used to play with sensors combined with a control circuit attached to the heatsinks to regulate the fans and this worked well. But now we have a direct source this can be the ultimate solution.
I am surprised by the varying results on temps but kipper2k,I agree with what you say about MS and they kept the fans slow to bring the noise down.
And also you're right that a small increase in voltage will give a relatively big increase in temp drop, especially on the gpu.
I am also interested in increasing the fanspeed through software. I'll do the rawconfig.bin edit but there is not enough info about this and success stories doing it are few.
Let me know if you found any info to perform this
