Ok, now I have it proven that cold is bad. 2.8ghz wouldn't boot up on my 9850 on the vapo unless it had like 1.4v. Windows boots up on 1.35 at 3ghz so far on my crosshair(XP-90c cooler), and the crosshair is still running on the first phenom bios which technically doesn't support the 9850 yet. I might have to get a water cooler this summer so I can ditch aircooling and just get new blocks when needed.
