First Build... Loop Help Required!

post #1 of 20
Thread Starter 
Hi Guys,

I've put together a VERY basic paint file and I have a rough idea of how I want my loop to go, however if any of you can think of any ideas on the BEST possible way to get this loop going I would appreciate an annotation and a post back on here.

The case in question is a Comos Ultra 2 and I am going to be cooling both the CPU and the GPU so whether a rad should be in between those two or not then i'm not sure!

Literally a complete novice!

Rad position does not really matter. The only reason mine goes from GPU's to rad and back to CPU was for looks and better tube routing. In the end the loops sort of hits a balancing point for fluid temp. It will all be about the same temp. The water does not get much heat from one block to the next as long as flow is good. Basically a lot of water is passing by and each tiny bit of water takes a tiny bit of heat. It's just doing this very rapidly.

Most important things are cleanly routing tubes with no kinks and getting a strong enough pump to keep flow high enough to keep things cool. Also having enough rad for what you are cooling. Generally speaking 120mm of rad for every block. More rad space means lower fan speeds and less noise. I have 840mm of rads for three blocks. I can run fans at a pretty low RPM and not really see temps go up. For a couple of blocks, at least 240mm to 360mm of rad is a good place to start. More wont hurt as long as you have a strong pump.

Excellent reply thankyou!

Just to clarify, it doesn't matter what order you put everything in along as it incorporates both rads so something like this should be fine?

This is showing:

RES > PUMP > 240mm RAD > GPU BLOCK > CPU BLOCK > 360mm RAD > RES

Res to pump is the only thing that must be in that order. Aside from that, pretty much what ever will make the cleanest tubing runs.

Perfect - one last thing...

What kind of fixings will I need to buy for the tubes? I get the theory and everything, just little niggly bits like this that I struggle to come to terms with - first time for everything I guess wink.gif

Unless I am blind, I have not seen where you posted any info on the tubing. If soft, I generally like compression fittings. But those are more expensive. Barbs and clams work fine too. If using hard tubing, they are all sort of the same but you need to see what plays nice with the tubing you plan to use. In any case you need to make sure the fittings and tubing are the same size. With compression fittings the ID and OD of the tube and fitting must match. Barbs, just the ID. Hard tubing, the OD. BUT, hard tubing can be picky brand to brand in both tubing and fittings. You will need to research that.

First build would definitely suggest soft tubing and compression fittings. I believe Mayhems soft tubing is comparable to the Advanced LRT from Primochill and cheaper. As for compression fittings, I'd suggest Monsoon, Bitspower, or EK. Never really liked the other brands.

As a tip, when you are putting the tubing on the fittings, dip the ends of the tubing in some hot water for a minute or so (not boiling, just faucet hot will do). That will make fitting the tubing fit onto the barb of the compression fitting a heck of a lot easier.

Sounds good, im actually looking at a Chinese version of a watercool loop BAR the water pump and tubing. There is another article about the rip offs on this forum under "Bykski Watercooling" looks promising and for my first build if things go wrong it wont be too inexpensive to fix for the time being, I am from the UK so not sure those brands you suggested are available but ill check it out anyway smile.gif

So, these are the compression fitters that you;re talking about DNMRock...

If I buy these will the standard 14mm tubing work perfectly with this?

If something goes wrong, your whole system may be trashed. Not worth that in my opinion. Buy the good stuff. It's not worth risking the whole machine to save a couple bucks.
