Yeah, my ambient temps are on the higher side. 2 G80's? Sure, that'll work with no forseeable problem, maybe then it would be an idea to split the loop due to flow restrictions as right now it's on the edge where flow/temperature effects can be seen. If the pump is turned below 2 CPU load temp goes up 3-4C due to flow issues, but anywhere above that pump speed setting temps go back down remaining the same within the 1C resolution of monitoring software. But good to think about should you want to add more stuff to the loop with 1 pump.

I really dont look at temps too much as they are so variable with my wildly shifting ambients and whether the fans are at 7 volts or 12. But full bore small FFT load with ~80F ambients/12 volt fans is in the low-mid 70's. Idle in same ambients with fans at 7 volts range 44-47C with the water getting warm. Keep in mind I'm at 1.592 idle/1.584 load vcore at 3.85 GHz, so heat output is rather high. Turning down the speed some 100-200 Mhz will drastically lower temperatures with this CPU. But that's not what I'm after, this sucker is right at the edge of where it will take no more...50 MHz more and it's not Orthos 'forever' stable, but at 3.85 it is, so that's where it stays, lol.
