What is wrong with aluminum radiators???

what is wrong with them and why do people keep telling me not to buy them over copper ones, Isnt there fluid additives that will stop rust?

More about what wrong aluminum radiators
  1. yes..rust and yes there is a lot of fluids for running mixed metals in your loop,the same fluid can cause other problem as well
  2. I'm currently researching water in preparation for my first wetbuild as you know Cia (Have Xspc Rasa RX240 kit all ready to go)
    and one of the common issues I'm seeing is mixed metals in loops,
    I'd rather avoid ally components altogether than have to take further measures to help avoid problems,
    too much hassle and another thing to potentially go wrong so I would stick with as few mixed metals in there as I could

  3. The aluminum and (specifically) copper in mixed loops like Moto mentioned above naturally undergo Galvanic Corrosion: http://en.wikipedia.org/wiki/Galvanic_corrosion

    Technically only Iron will rust, so any additives that prevent rust specifically will be useless because rusting is an oxidation process, and most loops don't have any iron/iron alloys (i.e. steel).

    The result in watercooling loops is something like this: http://www.overclock.net/water-cooling/141512-mixing-aluminum-copper-waterloop.html
  4. They said thats what happens after a few years I can save alot of money by buying a koolance kit 480 rad-shroud-fans comes prefab, so is it really that bad of an idea to buy it?
  5. Could you link to the kit?

    I purchased a Koolance rad recently (HX-480 120mm rad) and it's been redone from the older version. The new one uses brass tubing, whereas the old one used all aluminum.
  6. My blocks for gpu and cpu are 100% coated in nickle will this not work with alumiunum nickle isnt copper lol!
  7. There's debates about it; technically nickel is *ok* at best, but you'll have to maintain the loop religiously, because any crack/scratch/flaw in the nickel plating will lead to corrosion of the copper underneath.

  8. Wow your an demeaning person, A few years ago like when I was 8 lol, if you cant be nice I don't want your help stay out of my thread please, and this has been reported to the admins.
  9. Actually Ortoklaz is one of the most respected and knowledgeable W/c people on here I thought that last post was out of character for him to be honest,
    But I think maybe his patience is wearing a little thin,
    I'm not defending anyone here or taking sides, but if Ortoklaz tells you something watercooling related, its becuase he knows,

  10. Doesn't give anyone the right to demean people.
  11. As I said, I consider the post out of character and unless Orto tells me otherwise, I'm just assuming somethings not right with him, or his patience has indeed worn out :)
    I'm not saying his response was appropriate, I'm just saying its not like his normal ones

  12. i apologize ,bad day ;(

    EDIT; cleaned :love:

    Im sorry. that i am asking this many question im in a bind if i cut my case i will void warranty lol, Im going to start a new thread i would really like you expert in water-cooling to tell me what you think.
  14. don't need to start the new one..fire away

    EDIT; that's what you get from running mixed metals in your loop

    anticorrosives could do the trick but you would need a large amount of them in your water. That would hinder performance as well, as compared to distilled water,glycol based premixed coolants can clog your CPU jet plate in no time ,there are few that are not Glycol based like Thermochill EC6 or Nanoxia both around 14~18$ 1000ML,any way you look at it the risks are not worth it at all

    THe smaller version has great review says its top of the line, this is the bigger version i would prefer to do this over my own loop again tell me what you think sir.
  16. This is stand alone complete unit if i remember correctly ,you can put this on top of you case,is it good ?.. not by LC enthusiast-lazy man unit ,for the same amount you can build your own that will own this kit any day
  17. you want super quite stand alone unit for your rig ??
    EDIT ; that unit is also Aluminium !!!
  18. What case do you have and what are you cooling?
    You should be able to build a loop without much/any modifications at all. Really the most difficult part would be figuring out where to put the radiators. You can get one of XSPC's bay reservoirs and put the pump in there as well, minimizing the footprint of the system.

  20. Its aluminum what a pos i called frozencpu they told me the new rev is copper.
  21. My old loop was a fail i have 1xxspc 360mm rad 140m slim koolance 1 140m xt hwlab,koolance blocks

    if it's a copper (this would change few things) and you like it that much ..go for it,here is the reason
    _ this unit comes with sweet pump PMP-400,you can change the tubing (match ID size) from what you running right now and connect all your RADs or run two loops ,make sure it's copper
  23. according to KL they said that if i used there copper nickel plated blocks like i have it will not corrode this true or are they full of it?
  24. Are there any copper good all in ones like this kl kit or not Im sorry i am wasting all your time. I just don't know what to do.
  25. what are your temps right now whit what you have ..folding or load /ambient ?
  26. pump/res--->360mm rad--->2600k--->140mm rad--->gpu--->res/pump

    50c idle---80-90c folding/gaming
  27. this is at stock ??
  28. 4.2ghz at 1.28 volt, if i take over-clock off im at 80c.
  29. I guess i could get a quad 560 rad it figure how to mount it on the back of the 800d
  30. your temps are high for all the RAD space
    please answer all;
    where are you getting this temps ?
    have you flash your RADs before install ?
    what TIM ?
    CPU temp ? GPU temp ?
    is your pump running ,touch it see if it vibrates
    take your thermometer ..the one you get sick..stick it in your water/coolant at idle for 30 sec~record,wipe it good,now hold it near rad intake for 1 min and record again

    now do the same thing after 20 min under load/folding and report back
  31. the computer is apart but i have inline temp probes liquid it self was 50c at load after 30 min, gpu temp never went above 78c cpu temp never went above 91c
  32. Best answer
    ok looks like you don't want to cooperate ..no additional info ,here is what you stand on as far as i can tell the difference CPU/GPU temp is right
    you have enough RAD space for what you running at your clock..
    air ~27C
    water~50C way to high __A/W delta 23C__
    your flow is bad ,less flow -water will heat up
    now, before you start buying new rads,open up your blocks clean them,clean your RADs
    drop 140MM to the bottom of the case /let the 360 bread some air(that 140 is like 30FPI)
    apply MX-2 on CPU block,install all your components except one ..your pump/res
    spend some money on good fans and get yourself new pump
    good luck

    P.S. next time when you have bad temps with your set up ..start the thread "what's wrong with my temps"

    good luck CIA

    look at the temps (water) here
