Round Two :: LN2 cooling... whatever the board/CPU will let me do

Prepare to be disappointed...very disappointed. I was at least and expect no less from anyone else. It may sound funny but adding colder temps didn't help the mix, it made things worse. There was absolutely no gains to be had from this chip going from -35C to -85C - or anywhere in-between - at the same voltage. To make things worse, the board absolutely started to act like a childish school child past -50C. When I found out CPU clocks weren't going up no matter what I did, I basically packed it in for LN2 work as pouring anymore out on this setup would have been a waste. Needless to say, I got a slightly better 06 and 05 run in as well as some wPrime action...for what that is worth.

The good news is that the k|ngp|ncooling.com F1 EE mounts just fine with the existing hold down. As long as you don't need a back plate, you are good to go. Just use the 1366 holes as there is plenty of room for the rods to angle out slightly with the mount so high up. Here are the lack-luster results...

When I get better chips, this motherboard will be revisited with better results and a little more information about what exactly my issues were. It is hard to really button down problems or reasons for the problems when you only have a single board/CPU, and only a few days with the combo.
