780i SPP/NF200 (NB) Water Block from Viper John - Finally!!

[Philly_Boy]

Sheesh, I knew it would only be a matter of time....

I saw this on another forum but wanted to make sure everyone here saw it who is interested in cooling the massively hot SPP/NF200 (north bridge) chipset in the new 780i board.

My SPP temps hit 90c at boot up and easily get over 100c during benching runs with the POS air solution that nVidia provides. Here's the missing link to get the NB, SB, and mosfets cooled nicely. Can anyone say better overclocks...certainly more stable oc's?

Here's the link for more info, etc: http://imageevent.com/marginjohn/viperjohn

thats a huge nb block lol!!!!

does it interfere with the gfx card in the 1st slot?

It will not interfere with the card in the #1 PCIe slot. It's a big block because there's two hot little chip to cool...the SPP chipset (the 680i NB chip) and the NF200 PCIe 2.0 bridge chipset. It has to cover them both and have 4 point to mount to.

I have one on order...I'll throw it in a loop with my EK NF4 Rev 1.1 for the SB and my EK 780i mosfet I & II blocks for the mosfets and report my findings. I know my SB is hitting 100c during benching runs...this with a 50mm 19cfm fan blowing directly onto the nVidia heat sink. I am looking for 30c on the SB, 40C on the NB and 30c on either mosfet area....

[disruptfam]

kk sounds good.

I have a 680i and thinking about going to a 780i i already have the ek rev 1.1 and mofset blocks but i know the ek 680i nb block doesn't fit.

Looking forward to results

MIPS has released SPP and MCP blocks for the 780i. Here's a link for SPP version:

The same site has also the block for MCP:

I don't understand german but I'm pretty sure from the description that you can use the MCP block with 3-way SLI.

will this fit a striker ii?
and where can i get this?

[evil-98]

no wont fit the striker, i believe the PCI e chip is relocated near the SB but MIP has a block for the striker

[IanY]

I really like the size of the block, even if size itself doesn't say much about cooling abilities. The $75 is a bit steep.

The Asus Striker II Extreme... (Extreme and not Formula ! ) has its own built in NB waterblock, like the Maximus Extreme.

Aren't those pretty restrictive? It'd be great if it were just a waterblock for the northbridge, instead of directing the water through an arcane heatpipe maze over the MOSFETS and southbridge.

[Gunslinger]

EK has the measurements now for the NB and NF200 chip, so he'll also have a block available in the near future.

Oh yeah. They're restrictive. However, you wouldn't care if you were to build a seperate loop for that. After all, its only the chipsets, and once you get it out of the way, you can get down to cooling the important stuff.

I personally wouldn't put the NB with the cpu anyway. The SPP and MCP are hot suckers.

I agree...my SB hits 102c when I am benching

I want to get the NB/SB/mosfets under control so when I have to crank up the volts for extreme benching they won't hold back my other overclocks due to thermal instability. That's why they'll get their own loop with decent if not top notch components. (see my sig for the planned loop)

In all fairness, the Viper John block looks less restrictive than the MIPS solution so that's why it gets my order as I'll have it in a loop with three other blocks. When the EK 780i NB cooler comes out I will prolly order it and compare it to the Viper John block....and sell off the lesser performing block.

The WB is 3.100" long by 2.280" wide. That is as small as I could make it and pick up all four mounting holes and the NF200 chip too.

Negative on interference with the GFX card. The stock cooler is a heck of a lot closer.

REMOUNT the stock SPP/MCP cooler before your loose the MCP. The foam surrounds used on the stock coolers are to thick and do not compress enough to allow good cooler base to chip die contact....especially on the MCP.

When I first got my 780i MCP was running 70C_ but would drop 20-25C just by pushing down on the stock MCP heatsink with my finger. I pulled the stock cooler off and level cut the foam surrounds (just the surrounds) on the MCP, SPP and NF200 chip to .050" high then remounted with Tunig TX-II. MCP temps dropped to 45-46C after that with the stock cooler.

None of those chips are not particularly hard to cool. You just need a good mount.

As far as Asus Fuzion blocks go, do you really think something like this cools it efficiently?

[iandh]

For a production block I can agree, but for instance the CPU block I just made took me from 6PM on a saturday night until about 11:30PM, and then another 45 minutes to clean up the shop.

That would work out to about $8 an hour if you take out materials. In-N-Out hamburger starts at $9.25.

Alright, I hear you.

[taowulf]

Did he have to mention In'n'Out? I am starving and I haven't had a Double Double in years...

Oh yeah...nice waterblock.

The basic hamburger costs $9.25 without fries ?

Thanks for the sage advice...this board I currently have is getting rma'd due to the dreaded "FF" post code that won't go away. When I get the new board I'll be water cooling the SB so there'll be no worries....

[taowulf]

No, a job at the Shangri-La of fast food burgers pays that much.

Mmmm....Double Double with grilled onions.

Only reason to go to California.

Oh yeah, my parents live there too.

Um...isn't FF the code for when it is successfully booted up?

Do you mean C1?

[pvtdonuts]

No, theres a new bug where 'FF' shows up upon startup and won't go away, the C1 error was the 680i's memory issue

[Jedda]

780i is an improvement on the 680i in many areas but they've still got the same guy mounting the chipset sinks.
Remounting them should be done first thing out of the box.

@Philly Boy,
That S/B finger poke was fun with the 680i too. Watching the temps go up n down as the sink rocked back n forth.
