Thinking about water cooling...

post #1 of 7
Thread Starter 
Alright, I have a delima, my GPU is LOUD if I want to keep my 930mhz OCd 6950 cool, and it's getting really annoying, especially since it still hits 85C OUCH!

So I'm going to go water cooling, it's just going to happen, but I don't wan to just jump in, and not really know what I'm going to be getting into. As kind of a little side note, I'm going for stable and cheap, I don't care THAT much about my temps if it's lower than air at least, I want something that's less than $250.

I was going to get this kit: http://www.frozencpu.com/products/12...l=g30c321s1310

Yes I know it's a kit, and It might be cheaper if I pick out the stuff myself, but then that's something that everyone can help me with

A GPU Block for my unlocked 6950 ( Universal ): http://www.frozencpu.com/products/52...tl=g30c357s917

Ramsinks: http://www.frozencpu.com/products/71...C1L.html#blank

I still need to know how many though... would 8 be enough? This picture will be helpful if i'm wrong.

I do have another couple of questions, I do plan on going Crossfire, do I need a triple 120 radiator, or would a dual suffice? If it involves more noise, I'm not going for it.

My Case is an NZXT Whisper, and I'll be drilling studs into the top for the radiator to sit on, with room for the fans underneath, just in case you're wondering where I plan on putting the radiator.

My last big question, Is it really going to be that much of a difference if I'm going to go liquid cooling, instead of buying a good after market air cooler that isn't so ******* LOUD! I did look at this:

http://www.frozencpu.com/products/10...40c21s65#blank

and this:

http://www.frozencpu.com/products/10...40c21s65#blank


But how would the performance be and the noise, that is compared to the stock cooling that I have right now on my GPU, as I really don't want a lot of noise as I have mentioned quite a few time above.

Also as for water cooling setup itself, I have seen quite few people recommended "anti kink" coils, and they seem like quite a good idea, if I do end up buying the kit, should I add some of those too? The tubing that comes with the kit, is it enough to route from the front 5.25 ( pump / res ) bay all the way through the back, and then onto the top radiator?

No to anti-kink coils. Tubing doesn't really kink much, even the thin walled stuff (I'm using 7/16"ID 5/8" OD and have no kinking problems even with relatively tight bends).

The XSPC kits are great, but you want to go with the RX instead of RS series if it fits. For the price difference it's worth doing once and doing right. The kit is definitely the best way to go, but the RX throws you slightly over budget.

Is there any reason you want to go with a GPU only block instead of full cover? I've got a ton of airflow in my case, but I still prefer to keep as little fans going as possible, and you'll likely get better mem overclocks or less temp stress by having them under water, but honestly you probably know more about that than I do.

It is a big difference in sound. The reason I went watercooling in the first place was because my 6950 fan was driving me nuts even without eyefinity or overclocking, so once those possibilities came, there was no way I was sticking with air.

Performance will be better, noise will be less. You will just be poorer as a direct result of it

My main reason for cooling my GPU without a full coverage waterblock is just because of the expense, and the fact that I wont be able to take the waterblock with me to my next GPU, besides from what I've heard the ramsinks are more than enough to cool the ram.

As for the suggestion on the radiator, I really appreciate it. I have found two kits that use it, but I'm still wondering, if I do upgrade my setup for 2 Graphics cards, will I really need a 360mm radiator, or would a 240 do fine?

http://www.crazypc.com/products/xspc-rx240-93812.html

This is still going to be over my budget, but will I really notice a difference between the RS radiators and the RX radiators?

a cheap solution would be a Gelid Icyvision or somehing like that.

worked really good for me.
on 925/1375mhz its runs max 58 degrees in furmark and around 51 in gaming

on 965/1375mhz it runs max 61 degrees in furmark and around 53 in gaming

this with the fans at just 1200rpm.
Its really wisper quiet at the speed.

not better then a waterblock but alot cheaper and easier to build.
Does require 3 slots though so it can give a problem with crossfire.

For a GPU only loop, the rx240 would be a GREAT choice. I got a rx360 cooling 4 things in one loop, with fans ONLY in a pull config, no push/pull, and great temps, it would be overkill. I would make it simple yo, and order minimal parts, but highest quality you can. Good pump, good block, and good rad, all you need is tube, and proper fittings for the tube you choose, mebbe a t-line to "emulate" a res.

Try to find the parts used. Ppl here always have pumps and blocks. I recommend straight up... MCP 655 pump, the RX240 w/ push or pull fans on just one side, dont REALLY need push/pull if you wanna cut down noise, and a decent full cover block. After everything it might cost around $300, especially if you buy ALL new, but WELL worth it. You could easily add a CPU block later, and keep rad just fine. At that point you might need push/pull tho. Everyone will recommend Scythe Gentle Typhoon AP-15s or something of the sort, but those are $16/ea, and impossible to find now-a-days, new at least.

Remember to go distilled water only with no dye for best results, and some ptnuke or a silver kill coil for bacteria. The T-line / res idea is simple, add a t-line adapter, and let it stand up as a res. OR, get a res top mod for the pump, if you choose one they make the tops for. I also have a MCP350 with res top, and thats a great choice too. The 350 isn't really powerful for much more then one component in a loop, mebbe 2 max, but I wouldn't go past that. And for a pump like that, I would keep tube short as possible. Its tough, but not THAT tough, lol

Hope I helped, I consider myself a WC'ing vet, even tho Ive only done about 4 complete loops... Been through it ALL. lol

You will definitely be more than fine with the 240 since you're only doing the GPU and not full cover, it'll be more than enough. The nice thing about those XSPC radiators is that you won't need fast fans to get great temps. Now that I added crossfire 6950s overclocked and an overclocked CPU to my loop that my radiator does need more oomph from the fans to keep it cool, because my radiator has really dense fins (HW Labs GTX360).

Yeah, I have already put my 3870x2 in there, and a triple slot would cause a problem, besides I really want to see my whole computer being liquid cooled, it will undoubtedly help me when start over clocking bulldozer

A little beyond my budget, I just want to get rid of the noise, and if I'm at it, I might as well cool my CPU too.

I can always upgrade my stuff later, I do like the idea of a kit for my first WC rig. rx360 is overkill, but the rs360 is cheaper, would I notice a difference between noise? I have 4 case fans at 1700 rps, and I do know they are there, but It doesn't bug me.

So 2 6950's Unlocked and OCd + A power hungry CPU means that I will want to get a rs 360?
