Well, I took of the block and the AS5 paste was on perfectly as far as I could see.
I took off the front retention bracket to elimenate the bracket getting in the way, and also put some washers between the spring and swiftech hold-down plate to elimenate the longer threaded backplate.
I know flowrate is fine because of the time it took to bleed the loop....and because of the good performance of the GPU block.
For myself it's down to two things.
1/ bad contact between heat spreader and core
2/ faulty readings via motherboard (or faulty sensor in core?)
I also have a thread going on AMD support forum and they say the cpu would shut down at 60-70c, thus the temps are not being read correctly.
I might start a thread at the Abit forums and see if there are any issues with this board and temp readings.
For now I'm just going to assume the temps are reading too high and leave it at that for now.
I'll be switching over to socket 939 next month anyway, and when I switch the loop over to that system will then know for sure that it was misread temps.
At some stage over the weekend I'll reverse a fan to blow down into the RAD, and see if there is any difference, doubt it though.
Anyone got any pointers for 3 pin fans dont whine at 60-80 cfm?
I've seen these, which sound too good to be true? 80cfm at 30Db ?
