    Help with Watercooling

    Hey all,

    This is my first post of many I hope, I have running air ever since I got into building computers - I have decided to finally take the leap and switch over. I have my 920 running stable at 4.1GHz and while it is great I am getting some high temps, nothing to worry about but I would like to push it a little more

    I have everything picked out already however after deciding to go with compression with help from a friend they seem to have run out of stock.

    I am using 1/2" tubing and I was going to roll with these; http://www.watercoolinguk.co.uk/p/Bi...lack_1049.html

    I need around 7 as I will be rolling with 1 barb CPU block needs it. I would much prefer you stick to using http://watercoolinguk.co.uk however feel free to use http://overclockers.co.uk

    Appreciate the help guys, found the podcast after watching all of the This Week in Computer Hardware shows

    Looks to me like a waste of money. For one thing different blocks have different standard fitting so you can't be sure without careful study if they will work for you. But mostly the simple hose clamps that come with the blocks and barb fittings for free work just fine. That's 50 pounds saved.

    Also I would recommend 7/16"id 5/8"od tubing. They make a tight seal (you use the clamps for insurance and to prevent pulling the hose off by accident) and since there is less resistance at the fittings they flow as well as 1/2". They take up less space in the case and can bend sharper without kinking. Never had a leak over 3 years.

    A matter of taste but cheaper. If the barb is a little big, soak the end in hot water to make more flexible and stick it on. Will shrink to tighten up.

    At any rate have fun, and make sure there is water available to the pump at all times while bleeding air out of the system!!

    Re: Help with Watercooling

    I am really still a novice at this - I have put in my first order today and all I'll need after is the fittings and coolant. I like the idea you suggested - I will be going with 1/2" tubing as I said, I have a massive case with if not too much room. Getting everything laid out first will give me a chance to see what I need to order, I was told compression fittings are a much safer way to go ..hmmm I guess it is a whole matter of personal opinion eh?

    Thanks for the suggestion dude

    Some like the thick 1/2 by 3/4s tubing. the thickness resists the tube kinking when bent but the thinner wall tubing can bend sharper with out kinking (you can use zip ties to uncollapse the tube as well, also pre bend in hot water) which can come in handy especially with multiple blocks (chipset and or vid).

    I don't know about compression fittings in water cooling (I have used them in plumbing) but any method used improperly can cause trouble. As I said I have had no trouble with 7/16id on 1/2" fittings. With 1/2" id tubing you have to be more careful about tightening the clamps and you want to be sure not to cut the inside of Tygon style (softer plastic) tubing on some barbs when you tighten. At 50pounds (@$100) I couldn't justify compression fittings. I have to pay my sons college tuition. I have heard of some leakage problems but they have been rare and easily correctable The most common leakage problem is hard plastic reservoirs which is a different problem, as they crack. I haven't used one ever, a T-line works just fine.

    For coolant I use distilled water mixed with water wetter per directions on the bottle (at car parts shops) A 10-20% solution of distilled water and antifreeze is also commonly used. Higher if you have mixed copper and aluminum in the loop. Not recommended. No need for expensive stuff that is sold at water cooling sources. Note I said DISTILLED water, twice.

    Feel free to ask questions.

    In general shorter is better, and sharp turns are to be avoided but that can be a trade off. Kinks are unacceptable.

    Re: Help with Watercooling

    That is a great idea regarding bending with hot water - I will use that for sure I ordered a reservoir - the pump can be neatly mounted on it which is nice. I read about T-lines prior to my order and they just look like a total pain in the butt. My brother has actually trained to be a plumber so I could ask him (it has kinda been sitting infront of me the whole time, hehe) I know he has a roll of KTFE (if that is what it is called, the white ribbon).

    I know this sounds a bit stupid but I don't suppose you could link me the barbs/compression fittings I should use? https://www.overclockers.co.uk/showp...odid=WC-090-OK is the tubing. I think this would just help me back on track

    I really appreciate the help mate!



    Apologies for the terrible diagram I made

    Re: Help with Watercooling

    They sell the 7/16" I.D. tubing there. Second vote for that, been using it for over 5 years without a single leak. And I don't use clamps, just small electriclal zip ties, for peace of mind. Just get regular 1/2" fittings. you will still need hot water to get them on, but once there on... there on. OH Yea.... Distilled water ...only

    Re: Help with Watercooling

    Hey,

    I am totally puzzled - I am probably just a little off the track ( )

    I am using 1/2" tubing as was suggested by a friend - It will work with all my components I have been told and I have been linked to these previously http://www.watercoolinguk.co.uk/p/Bi...lack_1049.html which I planned on ordered 6-7 of, due to the HK CPU block I need to use 1-2 barbs. Now as you can see they are out of stock and I have also read a few people had their loops contaminated by flaking paint ..hmm. Could you link me an equivalent of that which will work?

    I am really sorry guys, I just feel I have just run a little too far out of my bounds and I am lost I probably sound totally stupid right now / don't make sense.

    Re: Help with Watercooling

    If this is the cooler then here, http://www.sidewindercomputers.com/hecpureforso.html

    On your diagram above, keep the reservoir above the pump to feed it, and you must be able to get all the air out of the rad. There must be no air in the loop.
    Suggested flow "res>pump">block>rad>res. Don't know it the res lower then the rad will cause the coolant to be siphoned out.

    Re: Help with Watercooling

    It will be fine I think, I have seen SOOO many people do it that way (Rad at top). That is indeed the CPU block I am using

    Lemme link you all the stuff actually;

    Re: Help with Watercooling

    I know it is done a lot, I was pointing out to you that you must be very careful to get all the air out of the radiator, as air doesn't conduct heat very well at all. Make sure you plan for that while installing.

    Fittings http://www.watercoolinguk.co.uk/cat/...tings_138.html You will need the 3/8 fitting for the Rad, 1/4 for the rest.

    http://www.watercoolinguk.co.uk/cat/...-Clips_84.html If you get the worm clamps, get the Mikalors, the other will cut the tubing. the plastic ones work fine as well they are thicker (bigger OD) which occasionally can be a problem

    That type of glued acrylic reservoir is the construction technique that has leaked so many times for so many.

    Re: Help with Watercooling

    Can you talk me through bleeding out the air & perhaps the coolant should I need to know, I need to keep it sterile which I have read...

    Also do you really see a problem in the reservoir? was told it was pretty good - I mean how do they go about cracking/leaking ..alot of heat?

    Cheers for help with the fittings, it is all a little clearer now I can apply the same BSPP to compression fittings right? (http://www.watercoolinguk.co.uk/cat/...tings_142.html I can only see one 3/8 =|) I was having a chat with my brother earlier and he knows surprisingly alot about this all aswell
