Idle temps mean nothing, show us some load temps and make sure you use HWiNFO64 to check VRM temps, they get hot on the DCII.
This is how I did my fresh install the other day. Install Windows, 12.3 drivers including latest CAP, wait for all Windows updates etc. Then, download the two files directly (not the patch) and place them in system32 and SYSWOW64 respectively. Reboot. THEN install Afterburner, don't start it. Go straight in and enable UOM. Voila! All works fine. I haven't tested games or benches yet because I've been busy, but I can confirm that UOM in afterburner works for me using that procedure.
Works for me?
While playing BF3 on max settings, I got a temp of ~60C. I'll run HWinfo64 while playing again.
EDIT: with HWinfo64 I got 79C (VRM), with @ 50% fans speed playing BF3. Any good? I havent OC'ed yet, still trying to learn.
