1 X 160GB Maxtor DiamondMax 10 HDD 45*C-48*C
2 X 80GB WD HDD unknown temp because run in RAID 0 Configuration, but touch by hand is around 45*C

No Front and rear casing fan at all, no HDD fan, because its only capable to low down 5*C only, useless for me...so u wun find dust on top of HDD....only one 12cm exhaust fan from my Acbel i-power gold 500W PSU....using water cooling currently...because i want extremely silent PC, can't stay with the annoying buzzing sound of the fan...
