Yup, I'm running the newest version. Just downloaded it 3 days ago to help me test my ram overclock. Topped out at 59c. Though come to think of it, it was only at 4.4ghz while testing ram and that was at 1.28v. Still, even 72 with IBT justifies a solid cooler. Now you could argue that a step down from the best of the coolers would be ok, but you certainly don't want to slum it if you are planning on any significant benching, or get the itch to push to 5.0. Now for those who insist on a full custom loop for SB, now that is overkill. Edit: Just ram prime at for about 20 minutes on 4.5, and topped out at 63c, still lower than what I'd get with IBT over the same amount of time.
