Now i would normally be the kinda person who replies to threads about cooling HDDs with "Not necessary". However, in my current build the only place for 2 Raptors (that will be Raid 0) is infront of the PA rad and hence will have warmish air flowing over them. The case itself has little airflow and so i am worried about them overheating a tad. I have looked into watercooling them but the blocks are large and expensive... but i had another idea i wanted to pass by people here. What about attaching an old waterblock to a copper plate and screwing the HDDs to this - would it work? Alternatively is anyone here able to make me a very simple waterblock that would consist of two parallel 10mm holes drilled into a copper block (that would be wedged between the two drives), and all 4 ends tapped for G1/4" compression fittings? Or is this just me being silly and HDD cooling is "Not necessary"
