"The fact that your 270X is screaming at you when you game implies that it's cooler is struggling to me."
What are you talking about? The most work the card does is render a blu-ray movie in conjunction with madVR. I don't think it's ever been hotter than 50-55 degrees Celsius...and that was while running a Unigine benchmark.
Right now, the card is 37 degrees and it has been streaming YouTube and playing movies all day. Right now, the fans are spinning at 1500 rpm. That is their slowest speed. Aside from unplugging them, they simply won't spin at a lower rpm.
Ah, Sorry. Made it sound like you gamed on it. Maybe I got mixed up with another post or thread. If so, I apologize.
