Here we go! Yearly drive replacement.

Last year about this time I made a post along the lines of "I go through a set of drives once a year."
Like clockwork, two of the four drives are dead, and one is on it's last leg. I'm getting sick of these mechanical disks. This is costing me too much but SSD's are ridiculously overpriced and too damn small. Even though I can get 640GB drives for 100 a pop, the investment isn't worth it since they're mechanical, they could arrive dead, close to dying or any amount of health. I'm sick of this crap. There needs to be another alternative.

It just defies odds that you have that many early hard drive hardware failures in a row. Not saying it's not possible, just highly unlikely.
Over the years I've RMA'd at least four hard drives, WD, IBM (not Hitachi), and Maxtor. Each time all the manufacturer needed was the serial number to authorize the RMA, after I completed their required troubleshooting. They did not require the original box, but reserved the right to refuse a replacement drive if they deemed my packing substandard. I packed the drives very carefully and received a replacement from each manufacturer.
*Everex will monitor drive temps as well.
Better cooling for sure, but my other thought for consideration at this point is that you might have a borderline PSU spiking your drives- a better rated one may help.
What are you doing to these drives that's hitting them with 60% fragmentation in a week? That's a lot of file file movement to cause that.
I've got the Thermaltake Toughpower 700. It's growing to a year old too. It's new to the drives, if that helps. They came off of a Aspire 500W. I needed more power back in October, so I got it.
Dunno, but you might wanna run through this calculator. Your PSU only has a total of g6A on the 12v lines. If for some reason your system is pulling too much juice, it might case the drives to get cranky.
YAD- like you say each 12V rail on that PSU supplies 18A and your 5V has 28A. Drives tend to use up a fair amount of each during R/Ws on top of the idle power like this. Remember also that many PSU specs assume a "Standard Day" temp like 25C but, depending on quality, can really roll off at higher temps.
I'd try to divvy up my drives to balance the load and see if that helps.
ADDED: Also note that your measurements are probably steady-state measurements- meaning that your drives, etc. are mostly dormant. If your drives are all active under heavy load, the 361 seems a safe number for power that is actually consumed.
Sometimes I really shouldn't be allowed to talk.
