Water cooling cpu and 2 gpus...2radiators

[Livinloud]

I have a 8700k and 2 1080ti's fe and wanted to do a custom water loop..I cant find a setup for 2 radiators besides they going into each other. Why can't the loop go res>pump>>gpu>gpu>rad>cpu>rad then back to start? Wouldn't going back into a radiator help cool the water back down before going into the cpu rather than gpu's into cpu then rad and 2nd rad?

Truthfully, you can have the loop run in any order you want. There is no right or wrong way as long as you have the flow moving forward correctly. I personally have my loop running Pump > GPU > Rad > CPU > RAD > Res

iirc JayzTwoCents made a video about it and said, the order doesnt matter

Thanks. Well guess me thinking way to hard into it. Haha

Make sure you are aiming for at least 720mm of rad space.

I can put a 240 in the front and a 120 on the back..I currently have an aio for the cpu..but my blower style 1080ti have to run full speed to keep temps below 70c. So my rig is super noisy. Ambient temp is 22c. I could put another 120 up top but any bigger I'll be hitting my mobo.

Unfortunately with a 360 mm total (assumed thin ~30 mm thickness) you will only just keep one 8700k and a 1080ti under control. I guess thankfully since SLI is so poopy, it is a rare occasion that all three heat generating components will be going at the same time.

So after research and checking..I can put a 360 in the front but it will only have 2fans on it. I have the phanteks p400s case.

So I could put a 360 in the front and then do a push pull on the other side of the bracket on a 240..but then little worried on space for res &pump.

You'd be better off buying a new case before sandwiching rads.

You could get the cooling capacity you need with a HWLabs Nemesis 360GTX in the front and a HWLabs Nemesis 120GTX in the back with push pull on both rads:

On paper it should handle everything even under synthetic load (stock speeds) at 1850RPM and a 1.5GPM flow rate. Realistically though, during gaming and such, you're CPU won't be pegged and your second GPU will consume less than the first.

Should work, just don't plan on any OC.

You ((((could)))) fit an EKWB SE 240mm in the top with some low profile fans on the outside of the case, and then overclock to your hearts content (plus just do push or pull as opposed to p/p on the other radiators), but then you'd be part of the goofy club.

Well I can currently overclock my 8700k to 5ghz with my evga aio with temps maxing at 76c but normally in the 60's. But the blower cards are just to dang noisy. Honestly it doesnt bug me as much since I have headphones on, but the wife complains about it lol. 

 

Basically I do SLI rarely. Normally I have 1 card mining new crypto under clocked and playing league of legends..and ya ya I probably shouldn't be mining because it isnt worth gpu anymore. (Its like winning the lottery now).

Just comes down to testing it, like I said a HWLabs 360 in the front and a 120 in the back can technically handle everything at stock speeds under synthetic load. If you're under-clocking one card and playing League with the other than you obviously have the headroom to OC, I question why you would in that situation, but I digress.

Should be able to handle it in some manner, you'll just have to figure out how you want to tune things.

Well my intent was to only buy 1 1080ti..and kinda got into mining new crypto where I could get a lot since it is new so risky ya..but then saw someone selling another 1080ti $400 and figured that was a steal and wasnt gonna let that pass up. So both my 1080ti basically cost the same as one 2080.

yea most important to jsut have a res feeding the pump that way its easy to keep primed when filling, and as you loop it up a few times you get better at making it easy to drain.

 

the only thing that matter is hard bends(angled adapters exist to prevent kinks, hard line never kinks if done properly) that make kinks/restrict flow.  other than that its mostly aesthetics.

I'm looking at the ek a240g or the 360 version and getting an extra gpu block and 120 rad. Fittings of course as well. Tubing going to try to use what comes with it. 

[Mick Naughty]

Don't see going cheap on such hardware paying off. My games run sli and if they could actually be pushed, a 360 ran would never be enough.  Prefer my fans run slow as that's one of the main benefits.

Please take into consideration that this is an aluminum Kit (entire fluid gaming series) 

 

thats what makes it cheaper,  also,  if you are fine with staying in the -Fluid gaming Only- accessories/fittings  upgrades.

Just keep that in mind if you plan to upgrade later on down the line,  you cannot mix copper/plated block with your aluminum loop

 

well you can, but you will have issues with galvanic corrosion.

Yes I know. Aluminum for all. Trying to keep my cost low. Going through reviews and post. Only thing really benefiting is the gpus.. which produces the most noise. If I slow them down they got 82-84c

i bought 2: 290X,  i voided the warranty before i even booted them to make sure they worked, thats how overly confident i was.

 

i cant say i regret having silent video cards either

benefits are getting  considerably lower temp 'readings'

 

But because how water works, its like TDP= 5w,  water deltaC=25w (random number for demonstration purpose only)

so you can run your system at 'full'  and it will only change the water .2C

 

This needs to be thought of for something called heat saturation, where no matter what speed fluid moves at, or fans blow air through the rad,   the TDP puts more 'energy' IN than the RAD can radiate OUT

Well I did ekwb configuration and says 240 and 120. But also that's about what my case can handle. 360 yes but only 2 fans on it.

thats a good start,  extra 'rad face' never hurts,  i run a 420/480 and have a 480/240 i could add in i wanted more extreme overkillingness

They aren't recommending  A240g & 120 they're recommending the PE 360 & 120 which is a better performing radiator, you're equating radiator size to performance but that's not how it works. Every radiator performs differently due to various factors, FPI, flow restriction, size, ETC. Your system is going to overheat if you plan on putting two 1080 TIs and a 8700K in a loop with a total of 360mm low end RAD space...

Even with the configuration they are recommending your system is going to run hot and loud:

If you plan on doing this seriously with all components in the loop I highly recommend you go with a Nemesis 360GTX & 120GTX. Also you can do 360mm in the front with fans across the whole radiator you just have to move the hard drive storage rack.

360GTX VS PE 360:

Since we are in the topic of water cooling, I can't find in amazon a fitting with a Valve in Canada to bleed the system.

 

I have the Thermaltake Pacific M360 Plus D5 Res/Pump PETG Hard Tube Water Cooling Kit CL-W218-CU00SW-A, so i would

like to have something that wont affect my system due to different metals.

 

Let me know guys!
