Finally i got the time to put the WC-blocks on.
NB goes down from 49-52celsius under load and air to 35.5celsius with EK NB S-MAX on naked core since the IHS came of when resested heatpipe in first place. need to have 1.61V on NB to get 4x1GB to work properly.
Rest of the loop is Dtek Fuzion, EK FC8800 GTX/Ultra. PA 120.3 and MCP 655.
SB went down from 45-48celsius to 36cesius wiht Thermalright HR05 SLl/IFX and an old glacialtech 80mm fan on that.
Dont know how well the HR09 S/U type 2 performs but hey are warm, the original was not.
