Nobody has to tell you that heat is bad for your computer, if you don't know that already you really need some help.
My situation is this: I have this stupid case with 3 3 1/2 drive bays, one of which is blocked off because of the mobo power cable connector which is rather large. (one word of advice, if you get a modular psu be prepared for bulky cables) So I am forced to mount my 2 hard drives right next to one another. Hard drives by themselves generate a lot of heat and with both of these right next to one another it's not exactly ideal. How much of a risk do you think I am posing to the hard drives by having them so close together?
Any input or advice is appreciated.
