This does not seem to be the case. I installed an aquaero LT 6 and various temperature probes located on both intakes, both exhausts and also inside the case. During idle the ambient temperature of my room is equal to the internal case temperature. Under full load (prime + heaven) I'm seeing about a 1 degree delta. Exhaust temperatures from the two radiators are anywhere from 5-10 degrees hotter. Not seeing that much air re-circulation as the temperatures for the intakes and internal case don't change massively.
11 fans wasn't the original plan haha.
10/12mm PETG tubing purchased from EKWB.
Yes. This Asus motherboard has a built in OLED display. You can display fan speeds, voltages, temperatures etc or even display a custom image.
Yup I ran out of coolant
haha yes. The 140's I had sitting around from a previous PC. Original plan was to have no fans on the modified front panel.
I did try for 3x120's on the modified front panel. Had to settle for 2 140's.
I've used everything from noctua to nzxt and find the ML fans the best for sound. Obviously not the best for high airflow but it's a compromise.
Did not pay $500 for ram.... I think it was around $300....
I wish. Stress testing on Prime95 at 5.2 ghz puts CPU temps into the 80's. At 4.7 ghz it's around 60 degrees. Gaming tends to hover around the 50 degree mark.
