Some heat could be reduced if two 8800GT weren't used unless they were gonna be used is some way for calculations...

That is true, but remember, we needed a cost effective solution to power 3 x 2560x1600 monitors. No easy feat. The 8800GT seems like the only decent card capapble. Also, they are the new Zotac cards, with the updated cooler, and larger fan, so they remail quite silent. Max ATI tool load temp I recorded was 69.

Those temps are much better - now go on and bench this monster until it screams. And take some pics.

Monday monday..... Haha, we had a few computers hooked to to the same circuit I guess, and after a few mins of Prime, blew the breaker!! Hahaha, what a massive machine. Will bench it tomorrow!

Here are some fun shots.

That's one heck of a rig. I knew the P190 was big, but that thing is huge. The inside is cavernous! I just figured out something with the high CPU temps: the airflow may be disturbed by the upper mid-case fan (the in the middle). What I would try is this: remove the upper mid-case fan; relocate both HSF fans as follows: one on the bottom, one on top in push-pull config with the exhaust towards the mid-case grill.

Any space to slip a 25mm-thick fan between the 2 HSFs?

I already thought about that. The best config is with the top front fan on low, and the top back fan on mid. Then more air is forced to go front to back. Also, there is not enought room for a fan on the bottom of the HS between the videocard and it. And no, not enough room for a fan between the two heatsinks either. I tried hahaha. I seem to have very decent temps now. With the fans the way they are, I get max 65 load. That is with 8 cores at 100%. I did a quick run of 3DMark06 and the max recorded temp was 48 haha.

48C while running 3Dmark06? That's very good. Now I want to see some numbers!

[Cptn Vortex]

Not the greatest score, mainly cause there is no SLI support on this board. Single card only. I believe I took the temp reading when I only had one fan on the heatsink. Those load temps came down.

That's a nice number actually for a stock rig. I don't know if you could run 2 instances of Prime95 V25.3 (found here: XtremeSystems Forums - View Single Post - New Prime95 v25.3 Full Support for Dual/Quad Core + HardwareMonitor v4.3.1.2) instead of 8 Orthos instances. Have you tried undervolting the CPUs?
