My good old IBM 75GXP died from overheat. It was in a warm environment so I put a drive cooler on it. The fan on the cooler seized up and the drive overheated. Damn drive died with 50 gigs of valuable data.
I was never bothered with the temps of my hard drives. Always the CPU but never the hard drive UNTIL last year when i looked to see what they where. All 3 of my drives where running around 48-50C. When i looked on the WD website i saw that my 2 western digital drives have a failure temp of 55C. Not wanting to kill my drives through the stupidity of having them overhead i built a HD water cooler to go into my CPU water loop and all is now fine. Personall the only component in my computer i care about is the hard drives. If i lose the data then what. Everything elese can be replaced apart from your own data. Get a fan on the drives and space them out. Buzz
