I mean they don't look like they can cut the job. Seeing as how they're mounted on the PCB side of the HD, which I don't think is where most of the heat is being generated from (the top side).

I've got a Atlas 10K II 10,000rpm SCSI drive and a Seagate X15 36LP 15,000rpm SCSI drive.

The space available for placing these HDs into their 3.5" bays are quite tight fitted and doesn't allow for much air circulation, if any at all.

I want to move them up to the 5.25" bays where there's a bit more room in and around. I have a full tower, btw. I'm tempted to get one of those HD removable racks with side mounted cooling fans, which I believe should do a better job since it is pulling fresh air from the outside.

I currently don't have any active cooling for the HD, or anything besides the fan on the PS for that matter. The Atlas has crashed several times for me lately, since it is now summer and hotter than usual. The Atlas has got some heatsink fins designed onto the casing, but I can still feel that it is very very hot.

Any thoughts fellas? Thx and appreciate any comments.
