Water-cooling

[yaboi824]

I know it doesn't make much of a thermal temperature to go from cpu to gpu or gpu to cpu, but if I get a Y splitter for the CPU and GPU to be separate and go to their own rads, would that be better in terms of cooling?

not really, since both loops ultimately end in the same reservoir again where the water mixes and the CPU/GPU still heat up eachother.

Only way to totally isolate components in watercooling would be to do seperate loops for the cpu and gpu. but that requires a big case and pretty much doubles the bill of materials.

the water gets cooled before going into the reservoir, and then goes to the cpu and gpu then into the Rads.

yes but no radiator is 100% efficient, and the water will still leave the radiator hotter than it was when entering the CPU/GPU block. 

 

what you're destribing with the Y-splitter is basically just a parrallel loop. those things have existed for ages.

So it won't make a difference with or without the y splitters? (btw I have 2 360 Rads)

not if in the end you are just going to mix the water together again. eventough one component may be cooled more efficiently this way, after the radiator the water gets mixed again and all the cooling differences just don't matter anymore.

it could work if you used seperate loops though.

Ok, so I shouldn't get the y splitter?

nope, i wouldn;t bother with this. just get a regular serial loop going. 2 360 rads is plenty for any normal build anyway.

By going that route the CPU won't be affected by the heated water from the GPU too much?

nope, but if you really are worried about that you could just go pump -> radiator 1 -> GPU -> radiator 2 -> CPU -> pump

I think the thing is, as its in the same loop, you get "even" temps after a few minutes, as the heating/cooling gets to a steady worktemp.

I cant say that happens. I have just one 420x40mm rad and have a res -> gpu -> cpu -> rad loop order and cpu temps are fluctuating way more and are around 5 C colder. Tho you will need to not its a 65W TDP i7 9700F and a 210W TDP msi radeon 5700 XT gaming X (going from hotspot temp measured by HWmonitor)

Still splitting the flow, so doesnt matter if it were to cool better. Flow wont be even, best to keep it series. If temps are a real concern build a better loop.

[airborne spoon]

dont bother to split anything its not gonna do much if anything.

I currently go res>pump>GPU>CPU>rad>rad>res and it all works great.

out of curiosity once i tried to go res>pump>GPU>rad>CPU>rad>res to see if there was any performance i could get by having slightly cooler water hitting the CPU. the water temp was a few degrees lower hitting the CPU obviously but i couldn't get any more speed out of the CPU with that and the loop looked a little funny. I am thinking about doing that loop order again but changing the design of how i run the tubes and if i can find a way to make it look cool i might do it. but what is nice about having it go res>res i can keep the fans super low under load
