Ill post one as soon as this my niece's kiddie party is over.

Not sure how the specs have changed for the latest Seagates, but the 7200.7 and ATA V Barracudas were rated for up to 65 Celcius. Anywhere below 60 if fine.
My air cooled (slow fans) Barracudas are around the low 40's depending on the ambient temps.
My SmartDrive2002 encased 200gb Barracuda 7200.7 hovers in the low 50's in warmer weather. This with a single 120mm fan at 5V for the intake. No exhaust fans.

'Cuda ATA V, 'Cuda 7200.7 up to 160 gigs, 'Cuda 7200.8: 0-60°C. 200 gig 'Cuda 7200.7: 5-55°C. That's what the datasheets say. It's not a bad idea to stay 10-15 K below the maximum temp. Old-style hard drives on the single-digit GB range could typically take pretty high temps but ever since the 10-20 GB per platter era I don't trust them beasts as much. The capacity explosion brought along too many models with only so-so or even bad reliability for my taste, including the infamous Deathstars and MPGs.

@ OP - Some of my favorite 80mm fans are made by Masscool, formerly speeze. Newegg has them for 1.99/ea. + 4.99 shipping. They are fairly quiet and produce a wonderful amount of air. Another helpful tip would be to lose any grill/filter/restrictive plate in front of or behind the fan. Some of the worst cases I've seen have about 30 micro scopic holes arranged in a circle. Very little air moves through those itty bitties. Well, good luck!

Oh I beg to differ.

My hitachi SATA drive gets up to about 37, my maxtor ata drive gets up to about 34.

OK I tried a few different configurations but this one seems to be working so far:
Case faceplate>>>Cool air>>>92MMintake fan on front of case>>>MUSIC HD (currently 40C)>>>PRIMARY HD (currently 51C)>>>120MMexhaust fan>>> 80MMexhaust case fan.
The 92mm is some kind of temp sensitive fan that varies the fan speed based on the air temp. I dont like it and I think the 80mm at full speed moves more air. Im going to switch the 92mm for a fixed speed fan or an 80mm fixed speed fan. I think the biggest difference is 120mm sucking hot air away from the primary HD and blowing it towards the 80mm exhaust fan.
How do you guys change the voltages?

@ OP - You might try a program called speedfan. As long as the fans are plugged into the motherboard headers, this program can vary the voltages. Just don't go pluggin' in any tornado fans.qqqqqqqqqqqqqqqq

Heh. Dual G5 @ 2.5 each:
CPU A: 76 C
CPU B: 74 C
Memory heatsink: 75 C
Graphics chip: 60 C
Processor cards (ambient): 55 C
Logic Board: 51 C
Drive Bay: 30.5 C
The drive sensor itself isn't connected, or inaccessible.

I'm more concerned over the fan making noise. |

Oh my! That's HOT! Those are IBM cpu's, right? I know VERY little about them. What is the ceiling on those things? Wow...

Don't G5's have a permanently sealed watercooling setup? It always sounded flaky to me, and if the chips are close to 80C, I guess that confirms it.

Yeah, it has water cooling, and when you open the side panel, there's a clear plastic sheet of duct work that you have to remove before you can access anything.
The CPUs are IBM 970fx, derivatives of the Power4 architecture. When I woke the computer this morning, the CPUs took about two minutes to climb from 50 back up to 76 C. Apple doesn't seem to publish normal operating ranges, but when I checked last night the machine had been active for eight or so hours.
In other news, the hard drive came up at 38 C. So even in the inferno that IBM and Apple have created me, looks like the best bet is to keep the HD cool.

These are stacked in a 3-drive cage in a Lian-Li PC6077, cooled directly by a Panaflo 80L at 1800RPM, from top to bottom:

Seagate 7200.7 (7200RPM 200GB): 48C
Seagate 7200.7 (7200RPM 200GB): 45C
Air temp 30C
