I have just RMAed my 680i A1 for the second time. The problem occurred about a month after I got the last RMA. C1 and 1D error codes are related to the RAM and the memory controller. I have extensively tested the memory individually for hours with memtestx86 no errors! I have the following specifications on my computer:

U2-UFO Black Powder Coat - Original Top
QX6700
evga 8800GTX in SLI
evga 680i A1 Motherboard
creative x-fi
4x1GB dominator 8500CD RAM
1KW PC power and cooling
PA120.3
fuzion on the CPU
MCW60 on the GPUs
Micro res
Laing DDC w/ Petra'sTech DDCT-01s Top Combo
1/2inch Tygon tubing

The conclusion I have to from extensively reading the evga forums is the MOSFETs are to blame. I replaced the ceramic on the Northbridge and southbridge and I have the Northbridge's fan maxed out. From my understanding of this post, http://www.evga.com/forums/tm.asp?m=78381, the MOSFETS just lack the proper cooling and degrade overtime until the memory controller dies.

I saw a watercooling part for the striker extreme to cover the MOSFETs, however none I could find for the evga one.

What are my options for cooling the MOSFETs besides just replacing the thermal compound on them (with Arctic ceramic)? Any help is greatly appreciated.

Additionally, do I need to water cool the northbridge or the southbridge?

Thanks in advance!
