Weird looking mod, let me see if I can decipher what you've done. I take you changed the airflow so that it blows up? I see your 60mm fan you have there, but it looks like you screwed it on to the factory fan mount. Is that just for ease of taking on and off? I was able to attach a 60mm fan directly to the fins of the heat sink. Also it looks like you attached the stock fan to the bottom somehow for extra intake from the bottom.

What were the temps originally? Mine stays fairly cool with the stock fan on so far. I attached a 60mm fan in both directions but there was no discernible difference for me.

How did you get the fan on the backside of the cooler like that

I have an antec spot cool sucking air out but ive found the temps to be worse this way

I think the higher pressure makes for better cooling, but there are dead spots when doing this

How does that bottom intake do anything? It can't suck in any air. Also, is that a Corsair Dominator on the right? I think it is, I might do that. Also, your CPU temps must have shot up quite a bit since you are blowing hot air on it.

You're brave I once had a nb fan pop off and brick an old gfx when it diced up some junk on the gfx pcb.

How is that fan mounted?

Everyone who owns an EVGA 780i hates the chipset cooling, and until SOMEONE CREATES SOME CUSTOM MOUNTS (hint), then we are stuck lightly modding it...
