Sounds like the CNB-S1L is the answer then. How do you attach the CNB-S1L to your Southbridge? Do you use the push-pins or are you using some other method? My options are thermal tape, push-pins and Artic epoxy.

For the Northbridge (NB), I'm going to use a Noctua NH-U6 fanless. I'll have a medium-speed Panaflo blowing a lot of air into the case sitting at the front of the case. I'll have the same type of fan at the rear withdrawing air out.
