eVGA 780i Chipset cooling !

post #1 of 7
Thread Starter 
Hey guys, need a little help to decide what steps to take next for my system.
I trust everyone here at OCN to give me some great tips and advice.
Thanks in advance.

So im feeling quite a bit of heat come off my north and south chipsets.
Its a little muggy in my room because i havent installed my window AC unit yet. Which i think is leading to the added heat, (my ambient temps).
I have a sliding left to right sideways window, so i have to hunt down a window unit to fit.
So this 780i chipset cooling system looks very complicated and i dont see that much room for me to do any major changing, especially with the new North chipset having the added BR04 chip to create the 3rd x16 PCI Express lane, while also providing support for the second iteration of the PCI Express protocol.
When i first received this board i stripped the coolers down to take a look at the tim on the chips and adhesive tape on the mosfets. It looked for once like evga finally did a good job with the tim. I replaced and replenished with AS5 although they did a nice job.

Here is a quick shot of the 780i without coolers.

Here is a couple quickshots of my vga cards, north and south chips and the oversized True. Hopefully this gives a little idea of everything built together. Also i have an OCZ Ram cooler over my memory, which is not really needed, just there for added cooling as my ram has a small oc.

So these are a few of the idea's i have come up with, please lend me your best judgemen and any ideas or if you have done some modifications already please let me know what you have done. Thanks

Mosfet Cooler: Thermalright HR-09 Type4

Southbridge Passive Coolers: Thermalright HR-05 SLi Highriser

This one fits under vga cards ive seen pictures.

Im not sure if i should keep the Northbride cooler or try to find an aftermarket one. Only problem is that second BR04 Chip.

Here is an article of a modification done by Chris123NT. This article describes how he replaced the South and added a better fan to the North while keeping the stock NB heatsink because of the extra chip.

Maybe i should go this route and use the Thermalright Mosfet cooler or keep the stock mosfet cooling and add a better fan to the North.
What do you guys at OCN think about all this info and data, which route should i take?!?
Thanks for the time out to read my post and thanks in advance for any help you guys give me +rep for comments.

So, he cut the heatpipe. But I still don't understand how he kept the fluids in the heatpipe.

EDIT: wait, nvm, now I see he only cut the SB part. I thought he also removed the mosfet cooler.

Yeah but i would like to know what that blue fan is he using on his NB.

Thermalright says its for SLI.

Bump.

Surprised that no 780i owners are freaking out about this.

I wouldnt do it, cant wait until he has to RMA his mobo.

People can get right around 45C by making sure they arent having pad issues, putting a better high flow fan on the NB, and then providing that fan with a spot cool.
