Will a single 360mm rad be able to cool a 3950x and 2080ti?

Recommended Posts

Posted · Original PosterOP

I'm planning a watercooled build inside of the Sliger SV590 case. It supports a single 360mm radiator, and I just wanted to make sure that this would be enough to cool a 3950x with no overclock, and a 2080ti with a max overclock. I also might wait until new CPUs and GPUs come out, but for now, is that 360mm rad enough to cool those components, with the overclock on the GPU, and no thermal issues? Thanks!

That depends, as not all radiators are created equally. In most scenarios it'll be plenty, but the thickness of your radiator will be the real teller.

Planning on using the EK Coolstream Se 360 Slim Triple https://www.ekwb.com/shop/ek-coolstream-se-360-slim-triple?___store=default

That's not going to get you far. It probably won't throttle, but its not going to be very good.

I use both a EK 480 PE and a 360 PE to cool a 3970X and 2080Ti.  I don't see how a single 360 slim radiator would work, even if you have half the cores.

I would say it’s likely to keep under 75c if it’s set up right and the radiator, blocks and fans are good.   Blocks will be most important.  The GPU will be producing most of the heat.  The issue with modern chips isn’t moving or disposing of heat it’s getting it out in the first place.  At max overclock on the 3950x you will be reaching the end of your heat envelope unless you’ve got a truly massive radiator. There may be some radiator fan noise.


Life is like a bowl of chocolates: there are all these little crinkly paper cups everywhere.

I wasn't planning a max overclock of the 3950x, I was planning on a max overclock on the 2080ti. But if that's just gonna make it too hot, I would be fine just going with no overclocks except for the RAM, which obviously doesn't get too hot and doesn't require watercooling.

 

To be honest, I would go with a larger case if I could, but I have very minimal desk space, and don't have the option to put my PC on the floor because my carpet is super thick and I'm worried that it would affect airflow.

 

Because of this, I decided to go with a vertical itx tower, which pretty much left me the options of the Phanteks Evolv Shift Air, the NZXT H1, and the Sliger SV590. The shift air only supports up to a 120mm radiator, which is nowhere near enough. The H1 looked really nice, but temps were pretty bad running off of a single 140mm radiator. Under max load, the 3950x in that case got 3° away from thermal throttling, and the GPU under max load and air cooling got 1° away from thermal throttling. So even though it's not throttling, that's still way warmer than I would like.

 

So that pretty much just left the Sliger for me. It has a lot of flaws, but it can fit a 360mm radiator and it's really the only case that I can see working for all of the things that I need. Again, I would obviously go with an ATX Tower if I could, but unfortunately I can't, and I'm basically wondering if temps would be good if I wasn't overclocking anything except the RAM, and watercooling both the CPU and GPU with the single 360mm radiator (https://www.ekwb.com/shop/ek-coolstream-se-360-slim-triple?___store=default).

 

The watercooling setup that I was looking to go with is this one: https://www.ekwb.com/custom-loop-configurator/shared/oW5f0932bb8d7fb .

 

So yeah, I guess I'm just wondering if this will work at all, and keep decent temps.

Also wanted to mention that the radiator is a slim EK version rather than a thicker one, not sure if that's helpful or not. I included some links.

What case are you using to fit all of that?

The cheap easy way to solve carpeting problems is a couple of bricks. Just put it on top of them.  There are also better looking solutions. A lot of height isn’t needed.  A thin radiator very possibly won’t cut it.
