Thanks for all the input, I really appreciate it. I do believe I used a little too much AS5 when I installed the 212+, a little came out around the edges. BF3 is about the most cpu intensive app I run, and temps never go over 55C.
The reason I left the door off was because I had no side intake over my PCI slots (old case) so in crossfire with the door on temps would go northwards of 99C on my second GPU. I installed a fan in the door on my case. I had to use a dremel to cut a hole out, but it was worth it. GPU temps never go much over 65 now, so overall my whole computer runs quieter with it.
Maybe someday I'll re-apply, but seeing as how the temp difference is only 5 or so degrees, I'll leave it as it is for now. I finally got crossfire working smoothly and got my CPU OCed nicely, I'd like to just enjoy my system for awhile before I go working on it again.
Edit: also I just knocked my voltage down 2 steps (whatever steps are on my mobo) and that lowered temps a few more degrees, things are starting to shape up nicely
