Cooling requirements for folding

[Dutchy735]

Hello,

 

I've been shopping for a new case for a while now because a single 240 radiator doesn't quite cut it.

 

I'm running a custom loop and the gpu and cpu share a single 240. I'm running my 3080 on 50% power to keep the noise down.

I was wondering if anyone has experience with either a dual 240/280 setup, or a dual 360 setup!

 

Edit: Cooling benchmarks never take folding into account, only timespy and cinebench benchmarks whatsoever. I could also hardly find any benchmarks featuring single cpu, gpu custom loop results with either dual 240/360 radiators. It must be more niche then I initially expected.

I aim for 50C gpu temp when folding so I'd wish to put the most power through the GPU while still remaining at 50C.

What CPU? Are you folding on it? Unless you want the heat output to heat your room or something (I have done this), then folding on the CPU is pointless. A 240 rad should be fine for a GPU and a CPU that's mostly at idle (F@H will use one CPU core/thread per GPU so it won't quite be idle).

 

What case do you have currently, and what budget + aesthetic were you looking for in the new one?

I'm rocking a 7800X3D, though I'm certainly not folding with it. my GPU temperature goal is 50C

 

I really like SFF builds! I will upload some pictures of my build tomorrow!

 

 

I was thinking to either go with a CM NR200P with dual 240, something like this

or a jonsbo i100 with dual 360.

I don't have any experience with SFF custom loop builds, so I can only recommend Optimum Tech on YT if you want to see more of that kind of build, or @Damascushere, he's an SFF fiend and has done quite a few loops as well.

 

I have run dual 360s in a full size case, and now I run a 360 + thick 280 (about the same performance as 2 360s) in a full-tower, Corsair 750D. I cool an i9 7980XE and 2060 Super with that. The 2060 S is only ~200W, but going off other people's numbers (my kill-a-watt broke) I believe my CPU should be somewhere around 400-500W all by itself at current settings. Based off wattage draw dual 360s is probably overkill for your setup, so I wouldn't stress about getting a case that fits dual 360s if it's going to be an overly expensive or difficult build (unless you relish that). No matter what size you end up with, you should be able to get rads that are optimized for low-rpm - usually sub-800 rpm - fans (my HardwareLabs GTS rads are, though I whack air through them with a bunch of Noctua F12s regardless), and there's a decent selection of fans that are practically inaudible at those speeds.

Right now it has a very dense radiator, 34 FPI I think. I'll have to get new rads I guess. so you think a dual 240 and a dual 360 don't make a lot of difference? not even in fan speed?

The very definition of SFF.

 

as promised, here is my build.

 

something I really like about it, is the airflow it has. sucking in cool air cooling everything inside, and spewing out the hot air from the top. It's like a wind tunnel and it performs really well. I'm not sure yet how to overcome this with a dual rad setup.

 

I edited my original post with a bit more detail. I must be a bit more clear what I want now.

It's another 240mm of rad space between the two, so it does make a difference. I just think dual 240s should already be plenty, so no need to go double overkill if you have to sacrifice too much. If a case checks all your boxes and clears dual 360s, then that's icing on the cake.

 

The dense rad with the 15mm fans is probably what's killing you on noise. They aren't Noc's quietest fans, especially when spun up to middling rpm, which they'd need to be to get much air through the rad. A low fpi rad should actually be better, as you want to be running low rpm fans to keep noise down, which obviously drops static pressure, making a high fpi rad less effective. HardwareLabs still claims pretty beefy capacities for their GTS rads:

 

I'm not seeking super silence and I got them because they were affordable, so I blast air through them anyways. Don't monitor coolant temps currently so I can't really offer much testing on how they perform with low rpm fans to see if it's close to the claimed numbers. But they are 16fpi and "optimized for sub-800 rpm fans", so they should do well.
