Hi. My mobo came with a fan to clip on the voltage converters. Seeing as my cpu fan takes care of that with the angled lower fins I laid the fan on my GPU which is directly below the northbridge heatsink so it can cool it

The fan sucks air in both sides of the blades and blows it out the bottom of it.
I propped it up on a folded piece of paper so it points in the correct location. Nice job imo:


Except, I can't actually get a reading of the northbridge temperature. So I have to guess by touching it after use. It is barely warm to the touch, yet the heatsink on the left of that pic is hot and so are the pipes - so I reckon it's working. However, is that even the chip I should be worried about the temperature of? It nearly burnt me before after I prime95 tested at 3.8GHz (auto voltage in bios for NB).

Does anyone have a resource for the temperatures and voltages that the nForce 780 chip is meant to withstand?

Anyway, that fan is quite loose... I may find a better way to fit it later - or buy a new cooling solution if possible.

I think NB can withstand 70-80c not fully sure but nice mod you did if it works very nice REP+.

Might want to set it manually to 1.25-1.35v in BIOS not sure might even need 1.40v but auto might be overvolting it so wouldn't hurt to try.

Since you have a quad and 4 sticks of RAM it will need more volts on NB and it will get a bit hotter because of these factors.

Thanks for the reply. Yeah, the only issue I think is that if it falls off then I will fry my NB lol.
