Water Loop Path - Page 2

post #11 of 24
Again loop order is not important after reaching equilibrium. You can claim that there will be a 2C difference at most. On the other hand if you are adding more tubing to achieve radiator->CPU->GPU you will again be getting a performance penalty because you are adding more restriction to your loop.

Long story short do not worry about the loop order. Go for whatever gives you the shortest overall tubing.

This minor amount of more tubing is not a relevant point.
Going with what suits your requirements best is a rather more valid point of saying that the loop order does not matter.

So if you do not care about the 1-2 degree loss of cooling performance and use of tubing is more of a concern to you then go for the loop order that is the tidest,cleanest and best looking.

If you are like me an extreme enthusiast and do care about the last 0.00001 degree^^ go for res->pump->rad->block because it will give you an advantage in cooling performance even if it´s only a marginal one.

This discussion has be said a lot of times.
And we all seen the pro's and con's of each. One rule of thumb is to always have water going into the pump.. well with that out of the way.
Loop order doesn't matter...as long as *different scenerios taken to account of course..is how you set up tubing.
The amount of tubing is to be considered, cause the more/less tubing is in the loop may not differ in temps much if anything...like said 1~2 C if you set up the loop correctly.
Also...I've had a very long loop in my HAF with my rad's stacked on top of the case.. pretty massive loop if you look at it.. but in the end.. it all matters with the delta you're wanting to achieve.
The "scenerios" will differ like I said before...some ppl can't have or rather achieve the delta's for there certain scenerio's if that even made any sense...
Through my experiences and errors.. a better routing scenerio is the key here...
"work with what you got".. e.g case... maybe some ppl don't have the space.. or what ever.. so you gotta deal with what you have..
These case companies are banking on us for wanting a full tower case that does it all.. Corsair..Cooler Master.. Silverstone.. Lian Li are banking on us for the NEED to reach that "best "case" scenerio"
With that said...
Another thing to take into account is Ambient temps..which ties into the delta's the user is trying to achieve..
Any loop can work.. hell some H50's work well for ppl... and others don't...
Loop order does not matter....as long as the pump is being feed the proper amount of water.
Then it goes from there...
The longest part for me when building my loop is trying to figure out how the heck ima route my tubes...and that should be in the minds of every new water cooling person out there...
I would suggest what the above poster suggests.. RAD before block..any block... just to have the "coolest" water to use.everything else will fall into place.

Is your space key broken?^^

I agree with you 100%

I do not care if it is 2 degrees or 0.01 ...the loop that has the rad before the block ,the least amount of tubing routed the tidiest and cleanest and a high flow will always achieve the best temps nobody can argue with that.

And I do not wanna start a new debate
But you should also make sure your rad can be supplied with fresh ambient tempreture so set it up in a push configuration and make sure the exhaust air is steered or routed to the outside of the case.
Best case scenario was if you had a TJ07 or Little devil with a bottom compartment in which the rad can be supplied with cool air and the exhaust air can be pushed right out the other side.
If this is not the case try to mount the rad low (if possible) so the exhaust air will either rise and be sucked out by your exhaust fans on top or do a push/pull in which the exhaust air would be steered to the backpanel exhausting area

So be sure about what you want and go for it!
cheers

It is a relevant point when you bring in details like loop order. This is just another fine detail as well. Like I said it does not matter how you set our loop up as long as you like the looks. That's what should count.

I meant that the extra tubing required in the rad->block order is an irrelevant point of not choosing it because this extremely minimal additional friction will be eliminated by the rad anyway before hitting the block.

Friction is really the most marginal factor of all and almost not worth mentioning.

OP you have had a remarkable amount of posts now
I am sure you will be fine and can orientate perfectly according to all our oppinions and advice!

Go to town on your water cooling and take some pictures

Well for some.. it's function over form..
That is where the "scenerio's" come in.. like how we can't really tell what a person is doing cause everything is different.. every aspect is different.. even if it's the same components or what not.
But.. from the get go.. it's mostly for the looks.. water cooling looks cool.. but once the looks go away.. it's more or so.. more of "how to make temps even lower" and then it's gets more crazy.. if you know what I mean.
To the OP.. I say do what ever you want.. and see what you can improve later.. it's like overclocking a cpu.. or this website for that matter.. WE'RE all about making things better.. look better.. anything we can do.
I still say with any water cooling loop.. make sure pump is being fed.. and all the obvious that goes along with it.

Good advice but I think my order still give me the better temps. Pump and all other heat is cooled before it hits the block.

c.)If you haven´t gotten a seperate loop and the dissipated heat of all components is dumped into the same resevoir before individually or at least partially having been able to go through a radiator yet the added up heat could possibly be overwhelming and have heat stroking charactaristics which also can enduce the cooling performance loss.

Disclaimer!
Please note that those factors have been determined by me and my long research and multiple tests of this matter.
Your experience may differ xD
I believe it is the best way as well.
