Corsair H70 change tubes help please

post #1 of 14
Thread Starter 
hi all:
i dont have custom water cooling but i did think about it.
instead i just bought a used corsair h70 (my first water cooling attempt)

anyhow i have a pretty big problem
i have:
NZXT Vulcan case
MSI 890GXM-G65 motherboard

right now i have a small video card in the top pci-e
the H70 is at the bottom front in a push pull config

my tubes BARELY reach already
i have on order the asus gtx580 DCII which specs says its 12" long

i know i have to change the tubes and even then the card might just be to long and hit the nipples on the radiator...idk

anyhow i want to change out the factory tubing and get some plastic tubing i think.
i dont want to add a reservoir
so what i was wanting help on is:

01 should i try and move the radiator to where the 92mm rear exhaust is and maybe mod it for 120mm somehow or get that 120mm to 92mm adapter?

02 are the tubes i need 8mm I.D. and 9mm O.D.?
if so where do i get this stuff?
i hope i can just drive to an automotive or fish store and grab some.

03 the hoses are going to add more area because they are going to be longer.
what can i "ADD" to the coolant already in the radiator and lines?

04 am i supposed to get "ALL" the air out of the system or do i need to leave some space for expansion?

05 do i have to "cut" the tubes to remove them from their nipples on the radiator and pump?
i mean cant i heat them up and pull them off somehow?

that asus vcard is 12" long and its a triple slot solution
i wanted my system to be quiet that is why i ordered that card and the H70

btw so far this H70 is AWESOME.

i had the cnps10x Extreme which is also an AWESOME air cooler

the h70 is just nicer because more space and also competitive in the temps and noise.

anyhow if you can add any help that you can think of please do.
thanks

Why in the bottom front? Why not in the back. I'd rather not hack it up when the back is just staring at me saying KISS!

I did my H50, you need to carefully cut the existing tubes off the rad barbs are metal the pump ones plastic so care is needed! I think I recall from reading up on the H50 somewhere the H70 tubing you need is 7mmID, could even be 6mm ID 8mm OD like the H50.

I would recommend you incorporate a small res like a swiftech, this will help drop temps a bit more, dropped mine by 5c. You will struggle refilling the system and getting most of the air out without a res.

Just pour the stuff out of the H70 and refill with distilled water and add an agent to slow frog spawn, swamp snot and various growths developing in the system. If you want nice colour like UV get coloured tubing and tubing anti kink coils rather than UV liquid for the system, thats what I read but ignored it and put UV feser blue in lol!

I cant say about the H70 as I havent modded one but another benefit of the H50 mod is I can run the pump at 800rpm instaed of the default 1400 and it makes no difference at all to temps, so it's quieter, not that its particulary loud anyway, and it should last longer...


Heres a pic of my modded H50 so glad I did it and got shot of them horrid stiff Corsair tubes!

it only takes 92mm fan (as mentioned above)
wont i loose alot of cooling if i use 120mm to 92mm adapters?
im not sure how i would do that
an adapter on each side of the rear case so i can attach 120mm fan and the radiator to them?

Is there room in the back to fit your rad? Sorry I missed the 92mm part.

1] Yes. I'm not familiar with your case and pics would help a ton, but moving the rad/fan would be a much better option than modding a perfectly fine H70 imo.

2] Should be 6mm ID and 8mm OD. Look on Ebay for deals in hosing, what I did with my modded H50.

3] Nothing, just run distilled water through it as it's a closed system.

4] Get every bubble out you can, sit there with the thing for 2 hours if you have to but get out EVERY bubble. Seriously.

5] Snip them to the nipple with a razor, then cut the sides and peel off. It's pretty simple.

Also, there is an official H50/H60/H70 club floating around, I'd recommend you go check them out if you have any issues. People have modded those things tons and the OP in the thread has tons of links to all the info you should need. smile.gif

Here's that club... http://www.overclock.net/water-cooling/612436-official-corsair-h50-h70-club.html#post7690988

It WAS a closed system, and is no longer so, once ANY outside air gets into it, IE cutting tubes/modding. It needs a biocide added to the distilled water like PT nuke......

Meh, when I did mine and closed it back up with new clear tubes I did it all submerged and never had any issues with it, but I can agree with that for peace of mind and all.

Edit***
Then again, I did sell it about 5 months afterward, but to that point it was clean and clear.
