Hi,
Im a big fan of the 780i Chipsets and specifically want the EVGA 780i FTW but since they released the version with the POS NB cooler which has some serious flaws when Over volting and hitting higher FSB
Read here "750i FTW" Since both the 780i and 750i FTW share the same Cooler

"Everything went well at first, but then errors started popping up. Even in those tests that the board used to pass flawlessly before. Had anything changed? Yes, the temperature. The chipset North Bridge started overheating after sometime. Replacing the small default fan with an 80-mm one didn’t solve the problem. We had to lower the chipset voltage, but once it lowered from 1.5V to only 1.45V, the system could no longer work stably at such high FSB and memory frequencies. We can overclock the CPU to the same 4.1GHz by raising its multiplier to x9 and lowering the FSB frequency to 455MHz, but even in this case 1.45V of the NB voltage was not enough, and at 1.5V we got errors.The chipset cooler on EVGA nForce 750i SLI FTW mainboard is efficient enough for nominal work mode, but during overclocking when the chipset voltage is increased, it can no longer cope. The heat distribution system is not designed right. The central heatsink gets scorching hot, while the additional heatsink remains just a little warm, because the heatpipe leading to it goes out of the middle of the central heatsink instead of its base. So, even though theoretically the mainboard can work just fine at 500MHz+ frequencies, in reality it turned out unable to cope even with 450MHz FSB. Maybe Nvidia nForce 750i SLI based mainboards are generally unstable during overclocking and high temperature is just another problem complicating things. Anyway, looks like we cannot rehabilitate EVGA nForce 750i SLI FTW, so all apologies are taken back."
Are they any After market coolers i that support the 780i? since it has 2 Chipsets the N200 it seems to me im pretty screwed in that regard, another question would it be possible to "fit" the 790i Ultra NB Cooler(buying one say from someone who has switched to water cooling) and put it on the 780i FTW? the 790i Ultra NB cooler looks by far better.
Any input would be appreciated!
