    Just installed watercooling.

    1) the water is like pink foam, i used the correct amount of water wetter.

    2) really high temps.

    3) my pump is leaking, its not the barbs, its the actual pump!

    4) where am i suppse to fill the tube res to?

    1) sounds like the res isn't full enough
    2) how high?
    3) erm... from where? did you over-tighten anything? did you use PTFE?
    4) i fill mine about an inch over the top barb. i put a credit card in to direct the flow downwards and stop it spilling over the top.

    right, i had the water level 1 inch below the top barb.

    yes i used PTFE tape.

    around 60degrees in BIOS.

    how can i get all the coolant out and do it again as its full of air and foam?

    thanks ALOT,

    1. Water wetter has been known to foam like a rabid dog although it most definitely shouldn't. If it does, there is cavitation present, i.e. air bubbles created in the pumping process, caused by air entering the pump.

    2. Foam is no good at conducting heat. If you have foam flowing through your tubes rather than water, temps will therefore be high. It should be OK once you solve the foam problem. I am assuming of course, that you have used a little bit of thermal paste between block and CPU.

    3. Which brings us to the pump. If water leaks from the pump, it is inevitably so that air leaks in at the same time. I bet this is causing the cavitation mentioned above, hence the foaming. Solve the pump leak=solve the foam=solve the temp problem.

    So, exactly where does the pump leak (and what pump is it, with what barbs attached)? We need to know this precisely, to determine the problem.

    Hope this helps.

    no air now, no leak now.

    but my temp is like above, my block has AS3 on and is making good contact.

    please help!

    theres about 1m of tubing between the rad and block, as its external from the case, is this length to large?

    does it matter about the inlet and outlet on the rad?

    Stay cool, it looks like you got the biggest problem solved.

    Now, check the flow. I don't know your setup, but I assume your cooling setup is in a separate box from the PC. First, put them on the same level (not PC on table, setup on floor).

    One meter may, depending on your setup, be a bit much (think about it: 3 ft there, 3 ft back, plus flow resistance of block etc.), depending on the pump you have. So what pump do you have?
    What radiator? What + how many blocks? Are all your barbs, tubes, the same diameter?

    pump: 1250.
    rad: bix
    blocks: neptune SoA.

    1/2" thick tubing, all barbs the same.

    250mm tube res.

    120mm variable enermax on the rad.

    around 50C idle.

    HELL YES IT SHOULD BE THE OTHER WAY AROUND!!! Oops, sorry, got my caps-lock on ;)

    The water should most definitely come in at the center of the block and leave at the corner. I mean, where is all the heat coming from? Center of the CPU (the die). So what part of the waterblock should be coolest? Center of the waterblock. When is water coolest? When entering the block. QED.

    Lo m8 yes the water should enter the block in the center and exit from the side.

    Yeah, but man, blowing water in at the corner. I mean, that is going to have every modder from here to eternity going: "Oi, Icecube, Noooo!" :D

    ermm might be a silly question but did you even let the setup run 48 hours before installation just to make sure everything is ok????

    right temp now is 34-36C as i tightened the waterblock.

    how much difference will changing the inlet outlet?

    whats the best way to drain the system and do this?

    id have to take the block off and everything, so ill only do it if its worth it.

    I was wondering whether you had tightened your block, but I thought: "Naah, that'll be OK" :p

    Yup, you'll have to do the drain thing. Having said that, 34-36 degrees definitely starts to approach what you should expect to get out of your setup. But if you want to overclock (and you'll want to), you need to swap the connections. I would first check however, whether you can't just swap the tubes to and from the block, at the other end...

    Majestix: not a silly question at all, m8. In fact, I bet he has been so impatient to try his new gear (and hey, can you blame him?) that he has just run the PC straight upon install. Otherwise he would have identified the pump problem earlier.

    Don't cut corners on doing this stuff, Ice! Don't want to fry your costly gear!
