I have a Corsair 600T, even running the front intake and top exhaust at full RPM, the Antec 920 cooler is struggling. I swapped a pair of SP120 PWM editions on and even on max fan speed it isn't cooling and I hit 91C almost instantly under load. Current setup here: (Both fans have been replaced with the SP120s not shown in pic) I was thinking of getting a Fractal Define R5 and a Corsair H110i to mount at the top. Previously I had a GTX670 that exhausted in the rear, and recently upgraded to the 970 that vents into the case. This also didn't affect temps too much, however I idle at 62C which seems insanely high. Even on stock clocks I idle at 55C. I put new Artic Silver 5 on today along with a new matched pair of fans with no luck, other than that would you guys have any ideas? Ambient room temp is usually 72F / 22C. I don't want to hear the fans running 24/7. So if I get the R5, I plan on having many fans all at a very low RPM. The case is on sale for $100, then I need the cooler, and possibly a set of PSU cables. Fun stuff...and expensive...which is why I'm trying to make do with what I have now.
