780i SPP/NF200 (NB) Water Block from Viper John - Finally!!

[ViperJohn]

I agree...my SB hits 102c when I am benching

I want to get the NB/SB/mosfets under control so when I have to crank up the volts for extreme benching they won't hold back my other overclocks due to thermal instability. That's why they'll get their own loop with decent if not top notch components. (see my sig for the planned loop)

In all fairness, the Viper John block looks less restrictive than the MIPS solution so that's why it gets my order as I'll have it in a loop with three other blocks. When the EK 780i NB cooler comes out I will prolly order it and compare it to the Viper John block....and sell off the lesser performing block.

REMOUNT the stock SPP/MCP cooler before your loose the MCP. The foam surrounds used on the stock coolers are to thick and do not compress enough to allow good cooler base to chip die contact....especially on the MCP.

When I first got my 780i MCP was running 70C_ but would drop 20-25C just by pushing down on the stock MCP heatsink with my finger. I pulled the stock cooler off and level cut the foam surrounds (just the surrounds) on the MCP, SPP and NF200 chip to .050" high then remounted with Tunig TX-II. MCP temps dropped to 45-46C after that with the stock cooler.

None of those chips are not particularly hard to cool. You just need a good mount.
