Water cooled GPUs tempreture ?

iAboodz · Oct 17, 2014

Hello guys, so I just finished my watercooling build which is the following:

XSPC 750 v4 res/pump
XSPC raystorm for lga1155
XSPC 240mm (For CPU)
EK 240mm (For GPUs)
two EK GPU universal blocks
EK terminal dual
mix of ek and xspc compressions and plugs.

Now the temps on idle are alright to me since i'm in a hot place, around 30 on idle and 27-29 on ambient. On stress lets say like bf4 the cpu was around 50-55 (i7 2600k @ 4.4GHz) which is still alright for me. Now what i feel not alright is my gpus, they are the same temps on idle as my cpu, but on bf4 they stay around 65-70. Is this okay or is it not ?

That GPU load 65~70c sounds kinda toasty for water cooling? :pfff:

I'd say you're seriously short on radiator cooling field for what you're cooling, 2 GPUs, but look on the bright side, that's better load temperature than the stock GPU air cooling was, Right?

This is a very common mistake of not having enough radiator to do the job, and is usually because of the desire to cram everything inside some small case.

My 2 watercooled 580GTX load temps never reached or exceeded 45c running a 360 and a 240 radiator loop.

So are you happy and satisfied?

iAboodz · Oct 17, 2014

Well I have TWO 240mm one for the CPU and one for the gpus, they should be enough don't they ?
Yes i do not want to install radiators outside the case, the 760t is just so beautiful to ruin it with an outside rad xD

And 65-70 is only on bf4 and furmark, i just played the new borderlands for a while and temps did not go over 56 on both cards.
I'm still ok with it, it's just that i used to run cpu + gpu on one 240mm and i did not get more than 55 for cpu and gpu and they were overclocked !

Should I go 360mm on top of the case for gpus and use the 240 for cpu ? And i'm suspecting the pump isn't enough :/

iAboodz :

I'm still ok with it

Well if you are satisfied with your results that's all that really matters!

I can only share how to improve your cooling load performance results, but if you're satisfied then I'll just be wasting my time.

Good Luck to You!

I do suggest you read over this.

iAboodz · Oct 17, 2014

Okay that's good thank you for that !
Although I'm still not sure about this. Could my pump be the issue ? It's an XSPC 750 v4 and I did read online that it's enough for my setups from a couple of people.

btw this is my setup: pump/res>240rad>cpu>240rad>gpu>pump/res

I really don't want to be the bearer of bad news but the XSPC pump sealed inside the reservoir is probably the worst move they ever made, it is a fixed speed pump which runs approximately on level 3 of a variable speed D5 pump.

Sealing the pump inside the reservoir is just flat out a bad idea when the pump fails you have to RMA the entire reservoir meaning you had better be sure you keep your old CPU cooler becuse you will be tearing your cooling system down.

A pump setup like the variable speed D5 either rear mounted to a dual bay or bottom mounted to a cylinder reservoir would have been one of the best XSPC cooling solutions, but they cost more money, and they cost more for a reason, they're the best XSPC has to offer.

IMO a stand alone pump and cylinder reservoir are even better as you can keep a spare pump on hand and when the pump fails, and it will eventually, you can swap out the pump and usually be back in business in as little as 30 minutes, (been there done that!).

The XSPC 750 pump/res is usually best rated for the largest kit setup XSPC sells any additions past that, (meaning more radiators and cooling blocks), are simply overloading the pump with loop flow restriction, the more back stress on the pump the harder it has to work and the sooner the internal bearings will fail.

I'm not trying to discourage you, we all learn from our mistakes and I've made plenty of them, you learn and then do not make the same mistakes later, when you improve your setup.

iAboodz · Oct 18, 2014

Yeah had that thought too.. I think i'll either be getting that D5/res combo from frozenpc or separate tube res.. I hope the pump isn't gonna fail meanwhile though. I also just realised that i'm being served by a water cooling genius. So thanks for the time !

4Ryan6 · Oct 18, 2014

iAboodz :

I think mine lasted about 2 years, so unless it has a manufacturing defect it should last a while and they have actually improved the pump bearings since the one I bought.

My suggestion would be use this time as a learning process of what you need to improve your cooling for lower temperatures of your GPUs and overclocked CPU, but keep in mind you're running 2 radiators and 3 water blocks, so I would say flow restriction wise your pump is close to it's max handling capabilities now.

You previously asked regarding a top mounted 360 radiator and many do that and it would definitely improve your present cooling, but I'm concerned regarding whether your pump could handle it?

That's why I said learn from this and use what you learn to go forward.

Thanks for the genius comment, but most here think I'm insane!

Guess i'll have time to get the 360 and the pump and res.
And insanity is sometimes better than sanity, we all like Vaas don't we

4Ryan6 · Oct 18, 2014

iAboodz :

I extremely liked killing Vaas in the game when I finally got the opportunity!

4Ryan6 :

We do yes, but i'd love to play in his character, am I crazy ?

4Ryan6 · Oct 18, 2014

iAboodz :

Not in reality I hope!

His character was extremely demented and sick, but what was to be expected by FarCry 3 putting untrained kids against someone like that in the first place?

He wasn't a darkside hero IMO, he was a pathetic wimp, and I surely wouldn't want to be like him at all.

What makes you admire his character?

Edit: Nevermind, This is going off topic!

I get around 43-46C highest GPU temps(idle ~ 25C-30C depending on ambient) on my GTX 690(dual GK104 cores) when playing BF4 and recording a temp log via GPU-Z. I'm using a single loop setup with 2 360mm and 1 240mm radiators also cooling my CPU (3930K @ 4.5). I'm running dual-pumps(MCP35X2) to move the water.

4Ryan6 · Oct 18, 2014

1LiquidPC :

Nice setup!

Got any pics?

1LiquidPC · Oct 18, 2014

I have pics on my phone, but never got around to deciding on a good free image hosting site.

4Ryan6 · Oct 18, 2014

I use photobucket.com

4Ryan6 :

LOL, don't get me wrong, in real life i'd shoot him in the face from 1 meters with a .50 cal. But in game, even though he's a psyco maniac the way he expresses his insanity made me just admire him, i'd easily make him the villian of the year. But yeah thats off topic so lets stop xD

iAboodz · Oct 18, 2014

1LiquidPC :

That's a really nice setup mate !
But two 360mm for one card even with two gpus is a bit over kill don't yuo think ?
On the other hand it's great incase of future upgrades

I also want to see some pictures, here's mine:

1LiquidPC · Oct 18, 2014

Nice PC you got there too, iAboodz! Here are a few of my pics. My S3 doesn't take very good photos when you look at them on a monitor vs phone screen. I need to improve my camera skills, lol. They were from during construction late last year which is why you'll see bags, zip ties, ect,

Also you can see my 3rd radiator if you look close at the super dark picture where I was testing the lighting. It's side mounted on the PSU side of my case.

iAboodz · Oct 18, 2014

Now that's a really good looking system you got there mate !
I aimed for a black and white scheme but white tubings were out of stock so i made it red, kept the white case and the white fan rings. I think it looks even better like this !

4Ryan6 · Oct 19, 2014

Both look great!

What case is that 1LiquidPC?

1LiquidPC · Oct 19, 2014

Thanks iAboodz! You do have an awesome color scheme going on there too. 4Ryan6, thanks for the comment too! Also, my case is a CaseLabs Magnum M8. This WC'ing thing is quite addicting of course, and I went about looking for a case that was a bit easier to move around than my 800D, yet could hold tons of WC parts. I stumbled upon CaseLabs and these Cube Style cases after some digging around. I always seem to have an idea in my head, and keep expanding the parts list somehow, lol. For the Rad overkill you mentioned earlier though, I went this route to keep temps low and fan speeds low. My old WC had a single 480 Rad cooling my CPU and HD 6990. Although temps were good, it was a loud setup to say the least with 38mm fans on the rads, hehe. Much happier now with much lower noise.

4Ryan6 · Oct 19, 2014

@1LiquidPC, I thought that looked like a CaseLabs case, I haven't looked over their cases lately as I have to keep my keyboard drool free!

I've been investigating cube style cases as I do want to house all of my cooling setup into one single case, as it is presently in 2 cases, but the case I'll probably end up with is a Mountain Mods Extended Ascension case.

It is large enough to house my Watercool MO-RA3 radiator, internally and my 2 Tec Chilling assemblies and insulated reservoir, both pumps and both power supplies, it is quite a lot to get into one single case and that is why it will require the large cube, of course it would probably take a small forklift to move it once it is completed! But it is on my Christmas wish list for this year.

1LiquidPC · Oct 19, 2014

Wow! I'd like to see that setup once completed

Your right about need a huge case to house all the cooling. Cubes are so much easier to work in, but in your case you've got a ton of parts to fit in. I haven't seen TEC cooling or Phase Change systems/pics in quite a while. What kind of temps are you getting these days? I do know what you mean about the weight though, lol. When I completed my setup(on dining room table, lol), it came time to carry my case into the computer room I was praying I didn't throw my back out, lol. Definitely not mobile for a LAN party.

4Ryan6 · Oct 19, 2014

My ambient room temperature right now is 25.8c my actual water temperature right now is 9.5c, so coolant wise I'm 16.3c below ambient room temperature, which allows my 24/7 stable overclock in my CPU-Z validation to the right.

The temperatures are constant and dependable and as of December 20th of this year it will have been fully operational for 2 years, with zero problems.

There was quite a long time of testing and experimenting before actually arriving at this present setup, and hopefully this Christmas I'll get the case I need to house it all in one case.

The TEC Chilled water cooling is for the overclocked CPU, and the GPU is traditionally radiator cooled, but it is one serious radiator!

I cannot say enough about the Watercool MO-RA3 rad, I still remember when I first got it in my hands, the sheer size and quality of construction! :ouch:

And it's performance is amazing!
