Hot Hard Drives.

[GuyClinch]

I have P160 with two WD hard drives a (250 and 80) I have a front fan connected to the "fan only" line on my Antec power supply. But it does blow some air.. My hard drives temperatures are 62C and 52 (according to speed fan). Isn't that crazy high? I mean the rest of my case doesn't seem that hot even my processor stress test for a few hours MIGHT hit 50 and it's overclocked by 20%.

Do they feel that hot? 62C is pretty dang hot, even if it isn't exactly egg-frying. Put your finger on the drive and see if it's really that hot.

there are three main variables to any heat transfer solution

the amount of medium being transfered to in a given amount of time
(in this case increase airflow)

the size of the transfer interface
(employ a finned heatsink to increase interface area)

the temperature differential
(decrease the air temperature your transfering to, twice the difference in temperature between the drive and the air twice the heat transfered)

in this case an additional factor or two could well be at play
radiation is another means of heat transfer, although a very small factor most of the time
two drives close to one another can be radiating into each other, still just a drop in the bucket comparatively, generally more to the point is the lack of airflow close proximity creates

Each 10°C (18°F) temperature rise reduces component life by 50%
Conversely, each 10°C (18°F) temperature reduction increases component life by 100%.
which applies roughly to both mechanical as well as silicon devices (there is obviously a lower limit)

excess HDD heat can be a sign of a bearing going bad, but unless you have seen a rise in temperature at the same ambient I wouldnt jump to conclusions

consider what a few simple air deflectors or ducts might do to force more air past the drives, as well as a more powerful fan, better location or accessory might offer
