Question about 780i NB block

post #1 of 12
Thread Starter 
I talked to Viper John and the price that he said for the NB cooler and his mosfets is more expensive than the EZ NB cooler and Thermalright mostfet cooler put together. Is it worth getting the Viper John one, do you think it's better than the EZ one?

Is the NB on that mobo so hot that a heavy duty NB HSF like this wouldn't cool it?.Swifty NB HSF..I would just use a HSF if you can get away with it...

Id get the thermalright for the Mosfet.I like the northbridge cooler except for the plastic barb's but none of the other stuff.I ordered the 680i mosfet and 680i II and another pc for my south bridge to water cool it all.

There is more than the northbridge chip under there. I wish I had taken a pic of the bare board. As for whether or not you can make 2 heatsinks work I dunno. I'm pretty happy with the Viperjohn block and glad I made the descision to go with his kit. The heatsink/fan that comes with his kit is more than enuf to keep the southbridge cool, so unless you die hard on watercooling the sb, I'd say go with the heatsink/fan on SB. I've only used his block for my NB so I can't give you a comparison, but I've read that his block is good for a cpl degrees cooler. As for the plastic barbs, I simply replaced them with two EK high flows.

i bought the EK Nb and Mosfet 1 blocks. my NB doesnt break 46C now

the only reason i got the mosfet block was because i needed to put something there and couldnt see spending 50 bucks for passive heatsinks(viper johns ) when the water block was cheaper. the other mosfet(the one that the stock HS setup didnt cover) is still only using the stock passive HS.



hope this helps

EDIT:

NB- http://www.petrastechshop.com/ek78chwaa.html

Mosfet- http://www.petrastechshop.com/ekmo68pa1.html

SB- http://www.petrastechshop.com/thhrhrislich.html

i went overkill on the SB but it is still the hottest running chip in my system . think i might get a block for that too. any suggestions?

Thanks for the links man +rep. I already have the Thermalright HR-05 SLI so that will be good for the SB right?

Do you think it would add to much heat into the loop getting the mosfet cooler? Viperjohn's mosfet heatsink might be easier, but what do you guys think? I cannot find the Thermalright HR-09 Type 4 anywhere either..

You need a special NB block because of the 780i having the 680i NB chip with an NVIDIA PCIE 2.0 chip.

Quote:
Traditional chipsets have two components: a north bridge, which Nvidia calls a System Platform Processor (SPP), and a south bridge, which Nvidia refers to as a Media Communications Processor (MCP). The 780i SLI follows this logic with the usual SPP and MCP components, but Nvidia adds a third chip into the mix to handle PCI Express 2.0. This nForce 200 chip connects directly to the north bridge and supplies 32 lanes of PCIe 2.0 connectivity that can be split evenly between a pair of physical x16 slots or even divided between four cards with eight lanes each.

people say the full block is better: http://www.petrastechshop.com/ekfucowaforn2.html


but it is more expensive than the little block: http://www.petrastechshop.com/dfugfxgpuwa.html

if you get the little block just put some memory heatsinks on like this: http://www.petrastechshop.com/cu98cokitbyi.html

there are cheaper options for the memory heatsinks if you want to look for them
