Watercooling Advice

340 Views 8 Replies 5 Participants Last post by  binormalkilla
So I'm getting interested in cooling my rig with H20. I've read through all of the essential threads.

There are a few unanswered questions i still have.

Firstly, what are the common pitfalls of watercooling? What's the mistake every noob makes?

Are there any brands to watch out for? Some dodgey ones? Ive seen rads of equal size and similar features for large price differences.

Finally, performance wise, what's the difference between your average single fan (like the size of one fan, what's the terminology i should be using?) rad and a rad that you can hook like 3 fans up to? I just want like an understanding of performance differences between sizes and how well it scales. (eg, is a good branded small rad, with the same price as a triple rad better?)

Cheers.

1. Only real pitfalls I can think of are people not properly securing the tubing on the barbs and not doing proper leak testing. This can be avoiding by having a little patience, and using zip ties/clamps/compression fittings.

2. My general rule of thumb for companies to stay away from: Koolance, Zalman, Innovatek, Thermaltake. Just stick with the good companies like D-Tek, Swiftech, Danger Den, EK, and XSPC (just to name a few) and you'll be fine.

3. In general, most people call single 120mm fans 120.1, and dual 120mm fan rads 120.2's. Etc etc. It all depends on your heat load, but I never recommend getting a single fan rad. Considering you can usually get a dual fan rad for like 10 bucks more than a 120.1, it's really not worth going with the 120.1. If you let me know what you plan on cooling with the loop (E8200 and 9600 GT, or what?) then I can give you a radiator recommendation.
My plan is to upgrade my CPU to an E8600 and buy a second 9600GT. Ill be trying to run the E8600 as fast as i can get it (4.5+).

I was thinking a loop for GPUs and NB, and one for CPU? Would both GPUs or the CPU put out more heat?
Make sure to leak test well the first time, as you may not clamp each connection very well, resulting in leakage. I would also make sure you clean out everything well the first time......use a water filter like this one.
You can keep it and reuse it on the next build too.
Another thing is to make sure and not use too much dye...it's really easy to over do Feser concentrated dye the first time. This will causing clogging, and it's a pain to get the gunk out of your blocks.
Stay away from Koolance....I guess that's the only brand I can think of.
The good ones are EK, Danger Den, Swiftech (especially pumps).
I would just stick with distilled with biocide, along with a little dye.
Also don't mix your metals (aluminum and copper, etc.), as to prevent a redox reaction.

Also, buy a big freaking rad because you can always cool more components in the future without having to add another loop. I did this with my 480GTX and I'm running 2 GPUs, 1 quad core CPU, and my NB with it.

For the 9600 GT, you're looking at about a 100-110w heat load each. North bridge will put out about 20-30w. CPU around 120-150w full load. So all in all, around 500w total heat. I would split it up into 2 loops, but you can do just one loop if you want.

I would do the GPUs and NB in one loop with an MCR320, and the CPU in its own loop with an MCR220.

Or if you would prefer a single loop, go with everything together with a Black Ice 480 GTX.

Some really excellent advice in the previous posts, but may I add:

Shrouds will help eliminate "dead space" on the radiator

38mm fans will provide greater static pressure.

...also... if you go liquid... you may never go back to air

Thanks for the advice all. This should set me up for my possible acquiring of components over the next few months.

+rep all around.

Oh yea I forgot to mention a shroud. I recently added some hollowed out 120mm case fans as a low end shroud on mine. I can actually tell how it redirected the air.....I could only do it on one side of my rad, as there isn't enough room for the cables on the case side.
