Truth is, i think i have a defective WD... but it hasnt given me any hiccups yet, other than it seems to be slow sometimes. It runs that temp about 20secs after startup. Also, i have 5 case fans, one of which is blowing directly on the drive and into the cooler.
I had some on my raptors, but ended up ditching them as they made some rattlely noises. I forget what temps I got before and after, but I'd say they weren't worth it...
and noone has suggested a 478 cooleR?
