Truth is if your only hitting 60 at full load after 24 hours u could OC higher, full load for 24/7 is unrealistic unless ur running folding really or something similar. Even gaming in the newest games is never gonna 100% load 4 cores for more than a few seconds at most. Great job on the clean up...
Im wondering what ur temps are gonna be like, sending the same air through 4 radiators will be interesting. The hotter the air gets the less effective they will get although thats alot of radiator so hopefully it will make up the difference.
Im assuming your just gonna blow air straight through? Pretty cool idea, i was kinda thinking the same kinda idea a while back when i was looking at another case, never thought about it on the 800d. Cant wait to see your results ;)
