Modding question !!!

[Ilijas Ramic]

Ok some guy sells an AIO cooler i think its a h60 for 20 bucks. I was thinking to mod that aio. Removing tubes and adding 240l radiator. But i saw the pump speed is around 6k, I cant find anything on the corsair website. Soo can the pump handle 240l radiator ? Its still gonna be AIO cooler but with bigger radiator. I was planing to use it on my gpu r9 380

Very doubtful that pump can sufficiently handle that radiator. The smaller radiator that it came with would likely have much less resistance (Less volume, fewer fins/tubes to add resistance to flow) for the pump to overcome. It would probably work, although at a lower rate than you'd want to see and would likely cause the pump to run hotter as it would be working harder, which would probably cause it to die a much earlier death.

I could be wrong on that, since I don't know (And neither do you from what I'm reading) what the exact specs are on that pump versus one from a larger system, but I think it's highly likely. I would think that for a larger radiator you would need a higher volume pump, since they always recommend when adding larger tubing that you also add a higher volume pump. Without a pump that is matched to the radiator and tubing volume, I feel like you are going to have a much reduced flow of coolant.

But the flow would be the same. and if the pumps runs on the same speed shouldnt that make no difference ?.

 

[Ilijas Ramic]

Hmm then is cheaper to buy 240 rad pump and make a custom loop

 

[Darkbreeze]

The resistance to flow would not be the same though. If you have to push a larger volume of coolant through increased resistance since there will be more volume to push around, more tubes inside the radiator to push that volume through and a larger distance to push it TO, those things will all increase the need for both a higher volume and possibly also higher pressure pump. At the least, a pump with a greater capacity in some form will likely be needed.

I'm not a water cooling specialist, but I do have some experience in this area and I DO have significant experience working with automotive and ornamental garden pond and waterfall pump systems, and that holds true in those realms so I have little doubt the laws of hydraulics are going to change simply because it is a PC rather than a pond or waterfall, or automotive radiator.

How about mixing copper with aluminium ? there is a combo for gpu block+pump from ID Cooling. But the block is made out of copper. Copper radiators are expensive asf

 

[Darkbreeze]

Mixing dissimilar metals is a recipe for corrosion. There are plenty of guides out there on the use of similar metals and which ones are the closest together in terms of compatibility. The bottom line is that the closer together they are on the chart, the fewer problems you will encounter. Also, there are plenty of AIO and customs loops that employ dissimilar metals which, if you use the proper cooling solutions that contain additives to suppress the reactions, helps keep problems to a minimum.

It would still be better though to try and keep within the same metal family if you want to avoid problems.

I know im asking too much. But i live in bosnia and we really dont have allot of options to buy here. Soo the problem is the coolant can i use car coolant mixed with distilled water ?

The issue is the diaphragm inside the pump. The pump on the h60 (its a 4k rpm pump ±) is rated to move the coolant at a 120mm radiators pressure. If the pressure is 1.5Lbs, figure the pump is good for 2 Lbs. When moving that to a 240mm, just because it's 2 x 120mm rads doesn't mean it's 2x the pressure, the pressure goes up logarithmicly, not linear, so the pressure is closer to 3x not 2x. That'd be like a 2Lb rated pump moving 4.5Lbs. It'll work for a little while, then either the pump motor will burn out, or the seals on the diaphragm will give out, pump is toast.

Dissimilar metals, especially copper/aluminium mixes suffer from electrolysis. It's a DC system, all hots run to ground, so expect a certain amount of grounded voltage running through the aio from various sources. The coolant itself being a strong pathway. The contaminants in automotive coolant only exacerbate this. So without proper precautions as mentioned above, something will give out that you cannot see coming, and you just sprung a leak.

Only a select few aios by fractal design, Swiftec and a few others are over-designed to be expandable. All other aios are designed to be what they are. You won't make a custom loop out of a h60 pump. It simply is nowhere near strong enough for the job.

[Darkbreeze]

I don't know about that specific product, but all of the ID cooling water coolers that have been tested by Crashman here at Tom's Hardware have performed really well and I've not heard anything bad about any of them aside from the fact that they seem to not have the greatest mounting system in the world. So the products are at least fair, maybe a little better than that, and if you look around a bit I'd bet you can find some professional reviews of that hardware.

thx

One question is this block compatible with my gpu? Im using http://www.sapphiretech.com/productdetial.asp?pid=421F760D-5247-4A25-BA5D-74A7A3139CD7&lang=eng

 

[Darkbreeze]

No, it is not. At least not according the specifications given on that page.
