Dual radiator for each cpu and gpu?

[hippiekid]

So I am doing my first water cooling build for my senior project this year. I am wondering if I can run the loop like the cpu water goes through one radiator and the gpu goes through the other one with only one reservoir? MY idea was kinda like Reservoir>pump> Radiator1>Cpu>radiator2>gpu>back to reservoir.

Yes, that is how you should do it. I would say that you need at least 2 240mm radiators for the GPU and CPU.

Okay I was just wondering because I see people going like going from resivor>pump>radiator>cpu>gpu>radiator>resivor so I was just wondering. But I’m planing on doing a 360 on the top for the cpu and a 240 on the side For the gpu just because I’d over clock the cpu before I would the gpu. Thank you though.

You can do that and it will be cheaper and will look better. But you will be running hot water from your CPU to your GPU to it will impact cooling. If you cool water before it gets to the GPU, then it will cool better.

I’d be using the same components just more tube. But tube is cheap. And yeah that’s what I was thinking and I couldn’t afford to do two separate resivor and pumps. I think I could still make it look nice because I have to present it in front of judges so hopefully it’ll look good.

You don't need 2 reservoirs and 2 pumps. By cheaper it depends on why type of tube you will use and if you want fittings in the joints. If you are using soft tube, then the price wont change much, but you may have water lines everywhere. Just make sure you draw it out on paper first so you know exactly what you want it to look like.

I’m doing hard line tubing, looks way better than soft. I forgot the more you bend it is the more fittings and stuff you have my bad.

 

[feelinfroggy777]

Fittings can really add up in the cost of the build. But they do make it look much nicer for 90 degree turns.

Yeah I forgot about that, but thank you for your help. Much appreciated

First of all, a 240 for every component is not necessarily correct. You should be looking at your loop component TDP in watts.

But you will be running hot water from your CPU to your GPU to it will impact cooling. If you cool water before it gets to the GPU, then it will cool better.

Secondly, loop temps are very similar at any single point in the loop. There isn't 'hot' water from a GPU going through a 'CPU' and making it hotter. I'm sorry, but this isn't correct.

Water has a very high specific heat and thermal conductivity level, so it takes a lot of heat in watts in order to even raise it 1C in temperature.
