Well... first of all thanks for the great answers!

I measure my temps with a senfu probe directly on the site of the core, and also with the onboard sensor via mbm. The difference is up to 12 degrees!.

My radiator is mounted above my PSU in my Addtronics 7896A, with a duct going from the top. So the case temp shold not influence my rad.

I have mounted the Maze 2 with Artic Silver 3 following the instructions on Artic Silvers site. Wich means a very thin layer on the core and rubbing the block with Artic Silver before mounting to fill all the small gabs. I havn't lapped though.

I did run the cooling setup for aprox. 24 hours before mounting it. Banging the rad. and the block to realease as much air as I could.

But I think I'll try to meassure my water temps and ambient temps to see if it's a mounting prob or anything else.
But how should i meassure the water temps? Is it ok to just stick a probe on the copper tubing on the rad?
