EK 680 Mosfet blocks on a 780i

[Serp15]

Has anyone had any luck getting their 680i Mosfet cooler block to fit on their 780i board?

I was able to get the 680i Part 1 to fit fine, but the part2 will not fit on my board. See the attached pics.

try grinding the board =P (j/k dont do that)
try grinding the block

[evil-98]

you cant grind the block, the holes are off line.

is there room to slot that hole without the block leaking?
if so, find a local machine shop, or one of the users here
with a mill that can slot the hole out

can we get a few more pictures, im not sure what im looking
at besides the holes not lining up from the back of the board

[Serp15]

I'll take some pics when i get home.

While your at it how about some pictures of the SPP, NF200 and MCP. Here's one take on water cooling the Mosfets ...

Or the 780i SPP/NF200 Water Block that includes the Mosfet heatsinks.

Improvise and adapt. Perhaps you can drill a new hole in the block, you don't have to drill all the way through just 2-3mm's then tap some thread and secure with a screw.
If you don't have the taps then you can buy from ebay for cheap, then I would suggest to practise drilling and tapping on scrap pieces of metal or even hard plastic. I did it for the first time last year and it's not too difficult as i'm not an engineer. Other than that you will have to buy new blocks to fit your mobo which will be expensive.

Good luck;)

p.s. I always loved viperjohns mods, gave me so much inspiration in the past, as a result I never throw away anything, i've got a box full of old heatsinks and other bits and pieces:D

[Serp15]

While I do appreciate the advice regarding possible solutions to mounting the block, the problem still remains the same. I purchased a block that Eddy from EK Waterblocks has stated would fit the 780i.

The block doesnt fit. Why should the consumer need to modify (and void their warranty) a newly purchased block in order to mount it to a board that was stated as compatible?

[Canadmos]

Did you contact Ek about the problem? That would be the first thing I would do, even before making this thread.

Then you're talking about this one ...

http://www.petrastechshop.com/ekmo68pa2.html

I'd think that whoever you bought it from would want to know before they sold too many. That and the #1 was on my buy list but since Eddy didn't yet have a SPP/NF200 water block I was leaning towards ViperJohn's solution. If it was me I would be on the phone if they have one or an email. Let's know what you find out.

From your first post I just thought this was a Mosfet you were swapping over to the 780i.

So your solution is simple then, return the block and have it replaced with one that fits. You failed to mention on your first post that your block was purchased to fit 780i which makes me wonder why you started this thread in the first place.:confused:
You gave me the impresion by your wording that you had already had this block fitted to your 680i and was looking for a solution for your newly aquired 780i.

msgclb: thats the one. another pic to follow. I also have paid ViperJohn for WB for the SPP/NF200. I'm going to be changing that to the full kit to include his heatsinks for the mosfets.

Did you contact Ek about the problem? That would be the first thing I would do, even before making this thread.

No I havent contacted EK regarding the problem, but I have talked to Quoc @ Petra's who told me that he did not think i received a bad block since they are created in batches and there was never visual confirmation from Eddy that the block fits (only that it should fit after looking at the reference design). Petra's has also offered me a full refund including shipping.

+1 for Petra's

This thread was created to hopefully gather some insight from those who own the 680i waterblocks and have attempted to mount them to a 780i.

I have not seen pictures of both blocks mounted so I posted to see if anyone has mounted both before I chose to RMA the blocks. Also, if this is the case for others (not being able to mount) I was also hoping to warn more community members who were contemplating purchasing these blocks (such as msgclb). Does clear things up for you?

[NaeKuh]

You guys are aware iandh is working on a complete board setup right now and you could easily ask him to make you another set?

And how do i know that Iandh is working on the 780i? Because its mine.

:]


And i currently asked him to put both mosfet northbridge and south bridge and the gay pci-e 2.0 controler all under water. And i dont agree with viper john about cooling the mosfet. The Foxconn board can NOT handle stress very well, so you want to eliminate all forms of stress on it.

Also the NB gets rediculously hot as well as the south bridge, and when you push the fsb on the northbridge your mosfets will also heat up. Also by watercooling you remove a lot of case fans. You usually only have fans on the radiator, and leave everything else to be cooled passively. Well sometimes this wont work.

Already ordered a set from viperjohn, but curious to see your set. Any current pics you can share?

he's still drafting it.

but i asked him to minimize on the barbs. Like 1 barb on the top mosfet for inlet, then 1 barb for outlet on the other side mosfet. Making the NB SB and PCI-E 1 block.

so it should be interesting.

[Serp15]

Sounds interesting, so 2 blocks total, 1 for mosfets, and 1 for spp, pcie, and mcp? That actually sounds really cool, would there be 2 channels going to/from the southbridge so you wont have any issues with SLI?

[msgclb]

Could you take a picture of the two #2 Mosfets: the original and the EK? I know it might be a little awkward but it sure would be evidence of the problem.

he doesnt have much room to shift the vregs and the holes dont allign which is kinda wierd.

The only option is either moding the block or moding the board. Moding the board is easier but more costly expecially when it has life time warrenty and you'd be killing that.

So moding the block. You would need to draw a hole on the area you need shaved down to fit, and then would need to mail it out to someone who has access to a mill. You first need to see if that hole will puncture the block.

Otherwise option 3. return the block, slap some enzo ram sinks on it, and call it a day, and let eddy know and wait on another revision. :T

[Eddy_EK]

Hi guys.
I havent had that problems, but few had come to me.
As far as I see the chips with R50 sign are sometimes installed a bit off the line like on the top picture. Which is causing the block does not fit because there is too little space. We will make more space in next revision of the block in march.

My R50 chips look worse than those in the top picture. You could call it the R50 Revision!

Hmmm....... Ummmmm.... Yea. Uh. I made the hole on my 680i board when the mosfet block didn't fit. Just like in the picture, the hole on the block was a little off. There didn't appear to be any traces around the hole, so...... took the screwdriver and widened the hole, then hand grinded a bit with a dremel bit.

But, I also don't care about warranty, as I'll pick up a 790 board when they come out.

later,

NaeKuh, I experienced this first hand myself last evening :(

I put Enzotech ramsinks on the mosfets but there is some problem with case airflow. Due to this, the corner just under the PSU isn't ventilated at all and one mosfet got burning hot when I'm trying to clock to 3.7 GHz that just touching it caused a BSOD. To solve this problem, I used zipties to install a 120mm fan on the mosfets area and it's now running stable and the ramsinks is cool to the touch. Like NaeKuh said, when you watercool your computer, you often remove lots of fans and this may leave areas without any airflow.

I started pondering about making 2 loops and put both mosfets under water but it's still about 150$ expense (extra pump and 2 mosfet blocks) :(

If you put ramsinks, make sure you don't clock too much or to have enough airflow around the mosfets area.

And this is why i said viper john is wrong. :up:
he's GREAT BUILDER dont get me wrong. But those mosfets need to be cooled. The board is not a great handler of stress.

Heres how i handled it xilicon. Maybe you can do something simular instead of that ugly 120mm fan

Perfect fit :D

[Xilikon]

I may have a great idea... Since airflow is almost nil around the cpu area, I might swap the rear 80mm fan around so it blow inside. I will then make a deflector from some aluminium sheet (I have lots from my case mod project) so it blow air toward the mosfets.

Another thing I will try if my first idea doesn't work well is to reinstall the stock mosfet cooler (I wiggled the heatpipe off the mosfet part so it's not attached anymore) then use the Asus mosfet cooler that I have on hand.

I might use my first idea because airflow would be more powerful and if it hit the corner, it will make turbulences and reach all the mosfets.

If all else fails, I have 2 70mm fans that I salvaged from dead IBM computers at work.

hope those arent from U2 chasis... they'd be kinda loud.

Ok yes, and you posted great photos which also helps the community Serp15.

[Xilikon]

No, cpu fans from NetVista computers.

Anyway, it's now moot because I ordered 2 mosfets blocks and 1 extra MCP355 pump (I can mod it to the 10w version, keeping it more reliable) to deal with the heat. The Enzotech ramsinks on the IO side row fell yesterday :shocked:

[IanY]

I have a solution! Strap 120mm fans and leave the stock heatsinks alone! just kidding :rofl: :ROTF:

This is why air coolers like to make fun of water coolers. We're supposed to water cool to remove noise, and after spending $500 on water blocks to cool a $250 mobo, we strap on a multitude of fans anyway lol :up:

lol.. very true... but eddy from EK said that they are going to have a revision of the EK680i Mosfet part 2 ready to be released in about 2 weeks! so strap those fans in til then!

And i dont agree with viper john about cooling the mosfet. The Foxconn board can NOT handle stress very well, so you want to eliminate all forms of stress on it.

You may not agree with it but it doesn't change the fact that my 780i Vcore Mosfet heatsinks
get the job done.

never said that your mosfet sinks didnt get the job done. :up:

I said i disagreed on your statement that they needed little to no cooling. Changing the sinks would mean you upgraded the cooling. On your article it sounded like you didnt need to pay any attention there at all. :up:

I still think your a great builder, and those sinks are definitely nice :up:

Can you point me to that please as I do not believe I said the mosfets needed "little
to no cooling". Of course they need to be cooled but water cooling the mosfets is
not needed.

After my mosfet heatsinks are installed the hottest components in the Vcore PS area,
by far, will be the Vcore phase series inductors (the R50's).

Sure. here:

Internally the Viper 780i SPP/NF200 water block has less flow restriction than a .400" ID
hi-flow hose barb.

You do not need WC on the 780i MCP. An EverCool EC-VC-RE cooler (available for $8.95
at SVC.com) will hold the MCP to about 40C which more than good for that chip.

WC on the Vcore mosfets is even more pointless than it is on the MCP. It does look cool
though.

Viper

If i was to read that, it sounds like they dont need any attention at all. :P

But i see your making a direct statement about it needing to be h2o cooled so i mistook your statement, and i appologize.
