EVGA GTX 680 FTW 4GB water block - hybrid cooling idea - Page 4

post #31 of 55

UPDATE 2

Unfortunately, previous fan settings were not sufficient. It was very difficoult to reach compromise between high load and low fan speed = silence, and stability. Every time on high load I had to turn the fan up to the 75% - 80% (TO LOUD!!!!) to chill VRM. Just like there was still vapour chamber. And thats truth, the design of the card is for air cooling, so VRM is more cooled when fan goes faster, and when goes faster obviously there must be load on the card and VRM works harder, giving out more heat.

I placed small radiators on any free space of the top of the inner alu plate, and this was hit in the point. It looks maybe little stuffed and ugly, but now it works as it should, efficient and quiet - max 60%.of the fan speed on the benchmark (over 90% uf GPU load). While gaming, the card rarely hits 70 - 80% of the load, so fan stays on 50% speed, and VRM is not hot at all. cheers.gif

Yeah, just crate a thread and gatter people. Let us know where you create that thread and we will join the party, I'm ready to buy two waterblocks, and I'm sure there will be many like me.

Hey guys I started a quick thread in the Nvidia Cooling Section. Here is the link. Please post in there if interested. Do you guys think I should put it somewhere else for more visibility?

Guys this is a very good mod. I just have a suggestion. I think it's best to use the black square waterblock shown at the start of this thread & maybe use a compression fitting to extend the inlet/outlet ports & just bore 2 small round holes to the side of the card. It would really look good this way rather than cutting a big hole.

Truth, looks cleaner and nicer, and requires less work.
The only thing is that the square block has the outlets bit inclined, and that puts SLI owners in small visual disordiance. I'm sure you could do the SLI bridge with elastic tubing, just maybe wouldn't be looking neat. The second option is exactly for SLI holders, and after bridging you actually don't see no cuts on the plastic housing.

It's hard for me to describe it will in English cuz my English is not that well.biggrin.gif Anyway, I'll just show you some pictures of what I was trying to describe about the ports. Let's just say that the mini DVD disc is the wall...







This way of cutting (2) small holes would make the mod look more professionally done. A shorter compression fitting & adaptor can be used for a much better look. That's the shortest fitting I got so I used that as an example.

This is a shorter adaptor...

You can probably do this to connect the waterblock inside the card. Let's just say that the left acetal piece is the waterblock & the right is the card's wall cover.



Minimal look on the outside with just (2) small holes done.

Iv'e got you idea :-)

Very good idea for estetics bro. Would have an awesome look.
Just different sort of fitting is needed. Like trough hole fitting.

Something like this:
http://www.performance-pcs.com/catalog/index.php?main_page=product_info&cPath=59_346_393_623&products_id=27482
plus four of very, very short fittings to earn some space between them for manovering.

or this:
http://www.performance-pcs.com/catalog/index.php?main_page=product_info&cPath=59_346_393_623&products_id=27482
But here the fittings are already too long.

Inside the housing of the card has to be flexible tubing, then you can try to combine this. But still, there is very little space between waterblock and wall of plastic cover, which makes it almost impossible to place two oposite fittings, find space and way to connect them with tube, close cover and get all screwed and tided. Which practically exclude the second attached link. Still there is an option to turn the waterblock 90* towards the fan, and try to make it with angled rotary 90* fittings, placing the holes closer to the fan, but also there might be a problem with space, and then with air flow, thus cooling very hottie VRM modules.

Take a look at thise photos of user USFORCES. You can see how it works in my case.

You have three (or less) cards with the same block.


And you connect them with just the same bridge as on the photo below. It doesn't look bad at all . specool.gif
