Question about Hard Drive Fan in Antec SX630/830/1030 Cases

Should I have the hard drive cage fan in the case blowing in or out in the Antec SX-Performance cases?

Even though normally it is recommended that the fan be blowing in, I think there may be some disadvantages to having it blow in. If the fan blows inwards, it would blow the warm air from the hard drives towards the CPU area.
 
but if it blew out, the system would be exhausting too much air. also I dont think the harddrive air is that warm to make a difference for the cpu.
 
It should definitely blow in. You want to pull cool air in the front and exhaust warm air out the back. In addition, since warm air rises, and the front fans are lower than the back, you'll also be enhancing the overall cooling. I have 3 of these SX cases and all have low case temps with this set up.
 
definitely in and across the hard drive...i'm doing this with the seagate x15 36lp which probably runs hotter than most if not all hdds and everything runs great
 
Harddrives make under 10 watts of heat, it doesn't really affect case temps.

Powersupplies used to blow in, but they blew in hot air over hte cpu and it made a difference. A powersupply puts out closer to 80watts possibly so it can make a difference to case temps.

Some harddrives actually put out less than 5 watts, that quietpc hd cooler only works on harddrives that make 5watts of heat or less.
 
Right now, I have all 4 of my fan slots filled up. I tried removing the fan from the HD area, and my temps actually did go down 1-2 degrees, but I keep it in there anyway. Reason being I'm running an IBM 60gxp in there, and apparently air-flow over them is the key to stopping their failure.
 
More importantly, if you have it blow out, you will short circuit your airflow in the case. Instead of taking air in the front at the bottom and exhausting it out the back at the top, you will take it in at the bottom front and exhaust it out the front near the middle. This will likely increase heat in your case more than blowing air across the hard drives and on to the processor.
