1-Will either be too heavy for the board?
2-Case Fit?
3-Memory Fit Issue?

I see that you use the core contact freezer would you recommend that over my two choices?

I will copy/paste my exact answer from that ^ thread:


Yes the megahalem is better but the CCF is alot better bang for the buck and you will only see 1-2c difference.

And there is a number of mods that you can do to the CCF that will lower the temps about 8 degrees.

Whew... there are quite a few mods.

1. Lapp your heatsink and your cooler.(this will drop the temps alot)

2. Make a "cover" over the heatsink to direct the airflow from the fan so it goes through the heatsink and not out the sides.

3. Add i fan on the other side.
