Thoinks foah the tip, mite!! [See answers to "other questions" at end]
[Really, Ah'm frum Tech-sus, tho . . . . y'all . . . ]
OK. O . . . . KAYYYY!!
I've got to search around here for my screen capture. AigoMorla is in the ballpark to exhort people to post "screenies."
Here's the basic configuration, oft missed in my many posts these last few months:
Striker Extreme motherboard
Q6600 B3 stepping -- lapped to the copper layer
ThermalRight Ultra-120-Extreme
Crucial Ballistix DDR2-1000 2GB 2x1GB
BFG 8800 GTS 640MB -- OC'd to 576/900 w TR HR-03-Plus cooler
3Ware 9650SE 4-port RAID5 w (4 x Seagate 7200.10 320GB) = 0.90 TB
"Spesh-ul" motherboard ducting: 2x140x20 intake fans (bottom); 2x140x25mm intake fans (rear of HDD cage); 2 x 120x38mm exhaust fans; 1x 80x15mm VGA fan
1994 Compaq ProLiant Server case, modded to ATX ff; capacity for HDD's, floppy, DVD = 14 devices.
EDIT: Mui Importante, Amigos!!
Seasonic M12 700W PSU
Yes!! There are "other" PSUs that will serve you equally well. I picked the Seasonic.

Now you'd want to see my CPU-Z and other data, but it's here in the text and I'm still wrestling with alternate screen capture utilities, so . . . . "trust me . . . "
Sooo . . . . O - KAYYY, I said, OK . . . .
I have the CoreTemp log files to process and get the "stats" on cooling.
At this room-ambient, the Blend-test core values don't seem to exceed a peak-core value of 47C degrees -- occasionally, it would go to 52C -- per my sporadic observation. The range between cores only occasionally would show a delta of 6C degrees, but mostly flipped back and forth between 3 and 4C. (This was due to the lapping.) The idle core temperatures showed a maximum delta between the cores of 3C degrees.
Now . . . . suppose I get those stats done, and the peak temperature shows as 55C -- I still have to process the data into Excel, and I couldn't just sit in front of the screen all night to watch for the occasional spike. The room-ambient was rock-solid all night at 65F. So at 80F room-ambient, we add 8.33C to the peak core value to show 63.3 or ~ 63.5C peak core temperature at a sweltering room-temperature of 80F degrees.
If the peak from the stats is lower than that, then the maximum core load temperature for an 80F room ambient might be around 60C.
KIDS!! You can do this at home!!
OTHER QUESTIONS
You can "do" 4GB filling all four slots, or 4GB in two slots, but you're gonna haveta loosen timings and make other adjustments. Last fall, 2007, I had 3GB in four slots w 2x1GB + 2x512MB. Those were all Crucial Ballistix DDR2-1000 modules. You can't just assume the same timings will be stable, or the same VDIMM is required.
Lopri is correct with wisdom about OC'ing with multiple components and especially 4 RAM slots filled, SLI graphics. Even for VGA over-clocking, you're supposed to run one vid card at a time to choose the over-clock settings, and under that circumstance it MAY be wise to flash the settings into VGA BIOS instead of having them implemented at boot-time through the registry. On the memory, you definitely must test them in pairs. These Ballistix DDR2-1000's seem to need slightly looser timings than the ones I RMA'd for replacement -- to get the same VDIMM voltage and keep it "tamed down."
On the BIOS flashing: I've used the floppy flash utility before, but for these boards, after a disaster with ASUS UPDATE [please avoid -- do not use], I only used the BIOS EZ-FLASH feature, and it works fine. ALWAYS BE SURE TO RESET BIOS TO DEFAULT SETTINGS FOR SPEED, VOLTAGES AND MEMORY TIMINGS. OR -- just Clear the CMOS before flashing, and follow the procedures in the manual carefully.
