Note that this is true more for the non GPU-accelerated version as the compute-heavy code is offloaded to GPUs when present. Take this with a grain of salt, but AFAIR both an i7 3770K and an FX-8350 with the stock fan and very well cooled case was running a lot hotter than any Prime95-based burn-in tests I could find. > > Regards, > BP. > > On Thu, Apr 9, 2015 at 1:18 AM, Szilárd Páll <[email protected]> wrote: > >> It should work but as others have noted, you may run into cooling >> issues.
