    Hi everyone, i have bought some watercooling parts for my pc and i am planning to watercool my cpu (amd phenom II 955) and a 8800gt. Of course they will be overclocked!
    The parts i have purchased are:

    XSPC 5,25' Bay Reservoir Silver
    XSPC Delta V.3 Cpu waterblock
    Koolance Radiator 3x120mm HX-CU1020H
    EK Water Blocks EK-DCP 4,0 (Pump)

    and i have a Zalman ZM-GWB 8800GT/GTS G92 gpu waterblock.

    The problem is that the gpu waterblock requires smaller tubes than the ones i have purchased (3/8 ID) with the other parts, including fittings. So in my purchase i have included one meter of the smaller tubes (5/16 ID) and two tube reducers so i can include the weird waterblock in my loop.
    I have this waterblock because i have purchased it a while ago in an offer from a local shop.

    Now if I include the gpu waterblock in my loop will it reduce my flow in critical levels and affect my temperatures a lot, or the flow reduction will be minimal or acceptable?
    Is it worth it or should I make a loop with my cpu only?
    I am planning to test my pump when it arrives with both tubes alone to see how the flow i affected but i would like your opinion too.

    Also i have the thermaltake uv reactive coolant. Do these coolants cause any problems or it is safe to use it in my loop.

    Thanks and I hope someone can help!

    I would leave it out simply because it's aluminium. Everything else in your water loop is copper, adding aluminium to it would cause corrosion.

    Yeah but my thermaltake coolant states that it is anti corrosive.
    If corrosion isn't the problem is it worth it?

    Yeah bad idea mixing up aluminium an copper, even if it states anti corrosive wouldn't trust it.

    It is a bad idea but I'm doing it at the moment <cringe>.

    I did it years ago and it didnt cause any problems but that might be because I put a few drops of dish washing liquid in my water.
    Or it might have been the Arctic Cooling anti algae fluid, not!
    Bizarrely I had no anti-corrosion in the water at all because I thought the anti-algae was anti-corrosion, oops, but it was fine.

    I can think of a possible reason why it might not have mattered before.
    The old water block I used had fat water channels that didnt really pressurise the water much and water flow down the channels wasnt fast, not compared to modern blocks.
    Because there isnt much force on the copper, its much less likely that the surface corrosion will be broken through so fresh corrosion is less likely.
    Maybe not :)

    The anti corrosion you can get may not even prevent mixed metals from reacting as that is a different type of corrosion called Galvanic.
    Free ions pulled from a large metal surface area can target a small area on the other metal causing a pit which grows.

    My current block is an Apogee XT and has extraordinarily fine copper water channels, so I imagine its going to be real trouble.
    But I'm itching to find out if washing up liquid is somehow a really good thing so I've foolishly set the same aluminium radiator on it again.
    Its currently using car radiator fluid (anti corrosion) and washing up liquid (anti algae and water wetter) in the water.
    I'll check it soon and see if there is any pitting.

    This block may pit without any assistance!

    Until a month ago I was running a Corsair(Danger Den) CPU block from a Nautilus 500 with a Zalman 8800 GTS block, and had no issues, ran that way for two years. I use 5:1 water/antifreeze.

    What about the water flow, does the zalman with smaller hoses reduce the flow a lot? Will i see a high temperature increase?

    was reading about this, designed to be used in loops with mixed metals.

    Never tried it myself, but if they say it works, i assume it does.

    Ah, you have to use only that, it cant be mixed.
    Might be worth a look.

    Does look interesting, i dont have mixed metals, but for those that do, maybe?

    Man, no one has just answered his question.

    The answer is no, reducing the diameter of the tubing is not going to affect temperatures.

    Put some antifreeze, or other anti-corrosion stuff, in there and, while not ideal, it will be fine.

    Thank you for your replies!
    So the waterflow will not be reduced a lot and it's not bad idea to install it in my loop?

    Deionzied water or distilled water combined with a couple of drops of PT Nuke is all you need for no ifs, no buts just maximum overclock maximum performance..."simply to simplify":)

    Try nano fluid,simlilar in name but not the same,this white fluid is supposed to be the lastest thing in cooling,i dont think much of it what i have read,giving 3-5 degrees in temps.

    No, I am still using 3/8, there's really no need for 1/2, the flow difference is minimal.

    I will not use 1/2 tubes, i will use 3/8 and the zalman block requires smaller tubes of 5/16 size. That's why i am concerned about the waterflow. The 5/16 tubes seem a lot smaller and no one uses them

    just dont get a apogee XT block unless you wanna nearly kill your flow.
    not worth all the trouble.

    What trouble, can you explain further?

    End of a review:

    Take special note of
    "Of all the blocks I've tested, it's the most resilient to low flow rates and when you add that to best-as-tested performance in normal and high flow scenarios, that equates to untouchable performance in low flow scenarios."

    :)

    problems with flow especialy with another block added.
    wich makes lot stuff harder.

    issues i had so far.
    trouble bleeding air out.
    low flow..
    besides their blocks out that are better i believe and aren't as restrictive.

    I see.
    not had any trouble bleeding air from mine but it may be harder with a more complex loop.
    Although I find that laying my PC on its side makes bleeding much easier but I didnt have to do that with this block oddly.

    Yes using this block in series can reduce flow to other blocks
    Have you tried running dual blocks in parallel?

    Which blocks are better, I'm interested to know?
