Bruiser:
The hardcano hard drive cooler mounts the hard drive in a drive caddy type mounting system and then it slides into a 5.25 inch drive bay
the temps you are seeing now are a drastic improvement / your componets will last alot longer at 30C then they will at 48C !!
Ebackus has posted normal readings of 38C / I personally dont like over 40C and like low 30's much better / most hard drives I think have heat protection set for 55C if I recall correctly / that the point they will do an auto shutdown
