Most efficient order for loop

[SocceRich20]

I'm about to redo my entire watercooling loop. Right now it goes like this:

Pump=>RBX=>Maze4 GPU=>Radiator=>Res=>Pump

The Maze4 will be taken out, as I have a 6800 Ultra now and it does not fit. Right now the Maze4 is just sitting unattatched to anything. I have a 2Fresh heatercore, and an AquaXtreme Pump. Here is a link to my pump.

What I basically want to know is: What order will yield the best temeperatures for my processor?

 

[Top Nurse]

Pump=> Radiator => RBX=> AquagraFX 6800 => Res

However, if it is more convenient to do it the way you had it then I don't think it will make a large difference except you are adding the pump heat into the block before it can be cooled off.

 

[Erasmus354]

oh stop it already TN, there is no way you want to use the Aquagrafx in a loop with an RBX. Of all the waterblocks the one you least want to add a restrictive small bore block to the same loop is an RBX/TDX. Face it, AC gear does not suit for every use....you could have answered the question instead of trying to earn your commision at sharka.



ON TOPIC : Order the loop in whichever way makes the smallest amount of tubing without having overly tight bends or kinking. That is what will net you the best performance. About the only thing you need to worry about is that you are putting your right after and right below your resevoir.

 

[mohammedtaha]

I don't understand why the maze 4 doesn't fit. It should fit on your 6800 Ultra according to Danger Den.

You should contact Danger Den and inquire about your problem

TN's loop order is the best order but it all depends on your system.

As for TN: your reply was useful until you added that unecessary comment.

 

[yang88she]

I'd have to agree w/ TN's suggested loop, as well as mohammed's question on why the maze 4 doesn't fit on your ultra

the maze 4 (along w/ the swiftech and fusion xl) is one of the best dollar for dollar gpu wb's, get some ram sinks and OC that bad boy too

and post up some pics when your done re-routing

Actually that cooler goes good with a 3/8 bore system. Beside where else would you get it from? I thought of the DD NV-68, but that thing is $25 more!

Nobody ever said that he needed a gpu + ram cooler. TBH most ram doesn't need even active air cooling, ram sinks work just fine. Also, we dont know if he has a 3/8" system or a 1/2" system. The RBX/TDX really need to have a lot of flow to reach their cooling potential and adding a more restrictive than necessary block to the loop does not help things.

I was thinking the exact same thing. I just stay quiet because I might end up getting myself banned.

Then SocceRich20 could just get a low profile Maze4, which will fit a 6800U, and sell the old Maze4 to make up at least the cost of ramsinks, if desired.

Interestingly enough with the advent of the OCZ RAM booster and the new DFI motherboards that are able to supply RAM with well over 3.5 volts RAM cooling has become a topic of interest.

Sometimes the difference of only 2 or 3 degrees “C” will make or break an over clock. There have been quite a few posts in the AMD forum about active cooling for RAM.

At the moment I am using a home built air tunnel with 40mm fans at each end, but WC would be much more efficient not to mention much quieter.

Not saying everyone needs it, but don’t toss the idea just for GP.

 

[typhoon43]

I have the acetal maze 4 on my 6800GT. How is the 6800 Ultra any different? They have an NVidia mounting kit for like 7 bux that should help you.
Here are pics of mine with teh "NV mounting kit" . I LOVE the cooler.

Wrong RAM Bill. They are talking about the DD 6800 block that also cools the RAM on the Video Card. While you do make a very good point about active cooling for system memory, thats not actually the topic of the thread. It is a very interesting topic of discussion, however...

In that case I stand corrected, however my vid card RAM gets damn hot too, although I can't recall that by itself ever being an issue.

Thanks

 

[SocceRich20]

I have a 1/2" system. I already have some copper ram sinks ready to go, so I may try to see if Danger Den will let me like trade in my old Maze4 for some credit towards one that will fit on my 6800 Ultra.

 

[madmat]

SocceRich20, if you've got the old alloy Maze4 GPU cooler you can get the acetal top from DD for around $25 with the 6800 mounting kit and simply pull the base off your current Maze4 to turn it into one that'll work with your rig for a bit over half the price of a new GPU block.

 

[madmat]

The top can be found here for about $20 with 6800 mounting hardware plus shipping.

Forget the AquagaFX cooler as it is max 3/8 ID. But you might want to see if you can just get the mount part instead of buying a whole new cooler.

No need to stand corrected. Video ram usually is hotter than mainboard ram, and active cooling will benifit the overclocker, albeit the benefit will be mild. Overvolted ram such as my BH-5 simply requires a little airflow to keep cool, the same with video ram.

To be honest, all the ram covers you see are simply for the bling factor, and people "think" it helps in cooling their ram. System ram runs cooler without the blingy heat spredders on them. They actually act as insulators, keeping the ram warm...

 

[rayman2k2]

though im not a fan with the idea of a reservoir, the best combination that I can see is pump > radiator > CPU > GPU > res

my belief is that the the pump can add extra heat to the water, sometimes meaning a stable o/c or an unstable one.

again, my opinion

A common misconception. Unless you are running one beast of a pump (Iwaki MD-30 or larger) the amount of heat added to the loop is a virtual non-factor, on the order of less than a tenth of a degree centigrade higher water temp.

Nice looking block but I wonder where DD got the idea to use acetal? Innovation at its best.

I tend to agree that the pump comes first but for a slightly different reason. Warm fluid has a much higher tendency to cavitate then cool fluid. As such the pump at the end of the loop could tend to be far less efficient, if not outright dangerous to your system.

Yeah it's a lot cheaper to "borrow" other companie's ideas than have an engineering staff on your payroll. And the mounting system too

you guys kill me. I'm all for innovation, but I'm also for competitive pricing. OMG THEY USE THE SAME X LOOKING THING THAT THE MANUFACTURERS USE ON THEIR VID CARDS, BUT MADE OF LEXAN!!!! WHAT POSERS!!! It's a solid idea, so why not use it for reataining the waterblock?

 

[R1ckCa1n]

I'm all about not supporting companies that can not come up with their own ideas and would rather troll forums looking for new products/ideas to release as if they came up with it all by themselves.

Funny how not one company used acetal until a certain waterblock was unvieled......

Seems all companies do a little borrowing. Name one that doesn't...

Ummmm all major waterblock manufactures except one.

And you absolutely possitively know this to be 100% true from where..the Inq?

Let's get back on topic, in general, the best order for components is one that will use the shortest distance of tubing with the fewest tight turns. It has been proven many times that the water temperature varies only by a few degrees throughout the loop, but poor flow caused by a series of extremely tight turns possibly resulting in near kinks would severely restruct flow, and increase temperatures more than simply routing your tubing to be less flow restrictive.

DD was founded before AC, therefore....

OMGZORZ AquaComputer like so totally ripped off DangerDen by making this thing called a WATERBLOCK that is made out of copper! I mean sheesh, they must have totally ripped the idea of using copper from DD!


You guys crack me up... to take a quote from family guy : "that tickles me in a way, that if Loretta tickled me in that way, I'd say, Oh yea ... that's nice ... that's the spot."

Hehe, excellent example
As for DD, It's BUSINESS man. If you don't protect your inellectual property, then I have no pity for you (can you tell I'm a capitalist, Microsoft loving guy?) The fact is that a lot of these compnaies are small, and just don't get the big picture. They're in this game for fun, and to make a little on the side. When they make a great discovery they post it all over the internet as fast as they can. You think big business does this? NO WAY. They have their employees sign NDA's and Secrecy filings, copyright/patent their product, and THEN show the world. I applaud Cathar for his knowledge and willingness to tap out a slug of raw (pick an exotic material) and turn it into a beast of a block. That takes skill, and no doubt he has what it takes. Now if Dangerden has something on their site or has said "WE WERE THE FIRST PEOPLE IN THE WORLD TO THINK OF ACETAL TOPS SO WE MADE THEM ", I might have an issue with them. Until you can show me proof, I'm not going to be a cool bandwagon hopper and start badmouthing a company that makes nicely performing blocks at great prices.

As for the loop issue, thanks for the post TopNurse. I never knew that was the proper order. I was going through my mind and your order would actually look better in my system, AND reduce the overall tubing length by like 30%. Sounds good to me!
My current path is:
Pump Outlet--> CPU inlet--> GPU In--> GPU Out--> Radiator in--> Rad Out..> Resevoir/Pump-In

Looks like I have a new project. Thanks!

Also, have any of you considered that perhaps people were asking for Acetal from DD?
People want Acetal topped NV6800s; there was even discussion at ocforums about custom making a bunch of them.
DD delivers what the people want, plain and simple. People didn't like the 3-barb design of the RBX? Enter the TDX.
