Hi and thank you all for your help, sorry for the delay, Yoyotech asked me to return the board to them so they could carry out an inspection and test to see if they get the same reading on the PWM Phase 3.
I've had to fire up the old steam powered pc to get back on line while I wait for Yoyotech to test the board.
I think you are all on the right track because on closer inspection the north block seems to be a little loose on the top corner next to the memory slots, not pushing to hard the block will go back towards the motherboard in this corner however it just springs back, as there are only two pins holding the block to the motherboard I think the heatpipes are pulling it away, apart from bending the pipes so it will sit correctly maybe the only answer is to replace the pins with a nut and bolt. Should the block be tight to the board or should it be able to move.
Fingers crossed I will receive a replacement which will work correctly out of the box.
Yes I did use the Abit program to flash the Bios which went from 10 to 13, this did help with the memory timings but made no difference to the temps, the block was hot to the touch but you could keep you hand on it so it looks like we are back to a bad contact?.
Just checking emails etc it would reach the 125 within half an hour.
Once again I would like to thank you all for taking the time in replying to my question and these forums are really helpful.
