Board is up and running and temps are NB 44C and SB 40C at idle. This compares to 49C and 40C on my other Crosshair IV. Ambient is 27C. I did not check the contact on the first system before I installed it, but with the difference in temperature on the NB I will probably pull the board tomorrow and check it out. If nothing else just to get rid of the crappy TI material that Asus uses.
Just got the other system back together and temperatures have dropped to NB 44C and SB 38C from NB 49C and SB 40C. The NB had some contact but not as much as the new board. The SB was barely touching and the plastic protective cover on the SB was not centered and was on part of the SB preventing contact. I am surprised that it was running as cool as it was. The standoff were loose on the NB and I turned them a little over a 1/4 of a turn (be very careful if you try to tighten these as they would be easy to break off). It took me several trial fitting as I didn't want to file off too much but ended up with a good contact pattern on both the NB and the SB. One thing that I discovered were that the screws have a shoulder that serves as a stop, so be careful if you try this and do not over tighten the screws and break one.
Took a little longer on the 2nd system but if you have temps that are a little high it is not really that hard to fix it. Just be careful and take your time.Edited by curlysir - 7/1/10 at 4:30pm
