Sorry for the lack of updates, got carried away. Installing the HSFs took me 1 hour, because the CM hardware does not fit well with the SR2. Some Dremel action was needed on 3 of 4 supports, and the CPU 0 PWM sink needed to be removed. I added some temporary sinks, I'll do some research for better ones.
The temp. sinks can be seen here, 4x. Ram is temp. too, waiting for some new sticks to arrive. And I need to flip over the CPU 1 fans.
Successful 1st boot.
