CPU and GPU in one loop

[Ner0]

Hey guys

I have a question or to regarding my cooling,
I have

1 120mm rad
1 240mm rad

openloop

currently cooling my 8600k @5ghz 1.28 vots my temps never exceed 70c while gaming only assasinscreeds origins and pupg pushes it that high, My gpu currently(sold to carbie) msi 1080ti gaming x runs about 75c on pupg after a hour or 2s gameplay other games alot cooler, I ordered the seahawk 1080ti with the ek block. Now i've seen benchmarks and test where those gpus run like 45c max on full load but they never show if its on its own loop or with a cpu

If i combine my 8600k and 1080ti on one loop will the gpu temps push up to the same temps as the cpu since its one loop?
Both rads are exhuast setups and i have 3 120mm af fans that suck cold air from the bottom of the chassis.

The tubing is a bit of a mess still new to the whole watercooling gig

any help or advice?

Connect your gpu after the 240 rad and between 120 and the run the 120 into your CPU
Can you not fit a res in there for some extra water volume even though it won't help with temps

There's a res on top of the pump

currently the flow is.
pump to cpu to 120mm to 240mm to pump,

my idea with gpu is.

pump to cpu to 120mm to gpu to 240mm to pump

if that makes any sense?

so that the 240mm can get most of the heat from the gpu?

Like i said i am not a pro at this but it makes more sense like that the cpu gan get colder liquid again?

as for adding a bigger res i can add one on top of pump but i dont see the need of more fluid?

I personally disagree that adding a rad before/after a component does anything to affect temperatures.
Unless people like Bill Owen and Tim Logon are completely bonkers; this kind of component ordering is unnecessary (you do always want your res before your pump so it never runs dry and burns out).

From what you have stated above, your CPU is hitting 70C with 360mm worth of cooling.

If I were you I would do the following:
- Do research on that 8600K (Pauls Hardware, Bitwit, OC3D, HardwareCanucks) to get a baseline comparison of how the 8600K operates under a WC setup.
- Try find reviews of the Seahawk, since it's an AIO you will definitely find reviews of people using it as is and not in a custom loop.

Just eyeballing what you have said my bet is overall your CPU temps will go up slightly (let's say 5C) and the GPU's temps will drop a decent chunk (say 10C).
I haven't gone deep into Coffee Lake research but an i5 pushing 70C on 360mm worth of rads makes me raise an eyebrow. Kind of makes me wonder if you should check your mounting + TIM application.

Good luck.

The rule of thumb is to at least have 1 x 120mm rad for every heat emitting component in the loop. Obviously having more headroom is recommended. So you'll be fine having both on the same loop.

Also, the order of components in the loop makes a negligible difference, it's a closed system with a certain amount of liquid that is in each component for no longer than a second.

The GPU OP ordered is the Seahawk EK X, the one with just a full cover block on, not the AIO version.

 

[Ner0]

Yes thats correct its not the AIO version its the waterblock one [MENTION=22168]Munk[/MENTION] [MENTION=34466]Ravin'[/MENTION] , as for the cpu hitting 70c only in assasinscreed origins did run the tests again pupg was around 54c, and as far as i know 70c at 5ghz on 6 cores in only one unoptimzed game is good. but i will post some screen shots this afternoon maybe you guys see something i dont. Loop order I watch one of jayztwocents videos regarding loop order seems its not something to actually worry about. And the pump wont run dry becuase the res is directly on top of it. Hope gpu does not exceed 70c XD

HEY GUYS JUST an Update

running

240mm pe ekwb rad
240mm slim ekwb rad
120mm pe rad

Cpu @ 5000mhz(all cores) 1.265 volts
Gpu @ Core 2012mhz, mem @ 5940mhz

Temps on cpu while gaming for 1 hour 60c average on all cores
Temps on Gpu 48C while gaming

is it maybe possible to drop my voltage a bit more? its currently stable but I know lower voltages equals better temps.
