Well I've got my third board installed, and this time I think I have the cooling kinks worked out, hehe. Tech where I replaced second board confirmed the SLI (NF200) and PCI-3 were cooked. They replaced it with new as soon as they tested it. I paid for IPR (Instant product Replacement) insurance when I bought the second board. Good thing too... Second board only survived a month of abuse, hehe.

I looked at different options for air cooling, but I think what i came up with (for air) is about on par with best possible, for sure better than what comes stock. I lapped all parts prior to re-installation, including the entire copper plate which I use as the heat transferral heatsink for the NF200/sb. I pulled the rest of (what I haven't already scavenged) stock cooling unit apart completely, and note that the block on top of the nb, with the fins, is made of aluminum. Below that is a copper heatsink that is of two thicknesses, which the nb chip sits dead center between each thickness (1/2 chip has thick heatsink; 1/2 chip has think heatsink). It wouldn't have taken much to design a better cooling solution to what they have. I could roughly draw one up in about ten minutes.

My sensor on the nb seems to be working spot on and , and I agree that the MCP temp in Everest is the same as the nb temp . My nb is now running at no hotter than 44c using active cooling.

Sensor on the sb is slower to react (perhaps it doesn't fluctuate temps like the nb), but shows a little higher (1 to 2c) temp than I had before, indicating that my new solution to cooling the NF200 is working.

I ramped up to 4500 MHz last night within an hour, and did some testing. It definately wasn't able to run CPU cores at 100% for long without overheating, but was fairly stable aside from that. I'm looking forward to breaking my old 3DMark06 score shortly. I ran Orthos for an hour before I went ot bed to heat things up, then let it cool off overnight. At 4050, this AM, my CPU temp is at 29c idle. Everything is looking good.

Pics to follow today.
