mrs Roo's pc has 2 120mm fans and now on water it stays nice and cool with its mb running around 26- 30,,, its cpu is now at 28-32 (2500+ @ 2.2) i droped almost 20c from the cpu just by adding the Cheap h2o setup to it , and it droped its case temp a few degrees (it has way better case flow then my 8 yo case does)
(These temp avgs are during the Evil Heat of the day here while loaded ,,and no we dont have AC)
When 1st installing a h2o setup its best to try to lay all components flat . then fill the system and bleed it . I cheated and left her cpu fan on .. cranked it up for a good bleed and leak check .. then shut down and mounted the cpu and radiator . (She's happy now ...I might even get to play pirate ...Har )
