Hi all,

I’m looking at doing a Mini-ITX watercooled build in a Corsair 380T case, using EK Coolstream SE120 in the front and EK Coolstream SE240 in the side.

Cooling Ryzen 3700X and RTX 2080TI.

Will these 2x rads be enough, my main objective is a mild overclock and quiet.

Regards,

Martin
 
2080Ti will chuck out 250+ watts. Let's assume the CPU will be using 50W, you're looking at cooling 300W or so. By way of reference, I have a 360x45mm radiator and a 120x30mm radiator, cooling a 1070 and i5-4690k. Something like 250W or so. It's not LOUD but it is certainly audible under load. I have it set up to stay under 55° on the GPU as I prefer quiet to cool.

I would suggest slim 240+120 will work but you'll have to compromise on temperatures, and it won't be silent. ITX is packing a lot of heat into a small space.

Sharing a decent CPU and a flagship GPU across one radiator feels a bit risky.

Had a similar build where I had a slim 240+120 in a h200i. Cooling an OC'd 9900k & 2080 Ti. Had to have the fans spin @1500 rpm and temps were around the high 80's for the CPU and around 60 for the GPU.

1500rpm is definitely audible but not too intrusive. If I were you I would get better radiators.

If you want a really quiet build (around 1000rpm) then you will either need more radiators or be ok with having your GPU around 70+ degrees.

Can you use one thick 240mm rad? To be honest one would probably be enough.

I don't think that will be enough, it is a slim rad as that is all i can fit.

Thank you all for the replies.
I don't think it's going too work well in this case, I can only really fit a slim 240 in the side as it will be close to the mb, I could fit a larger 120 in the front, but I don't think that will make a massive difference, I really what it to run quite..
Dam time for a larger mb etc :(
 
I think there is a dependency on airflow to you case.

I also have a build right now 120mm SE and 240mm SE in a Phantek's Shift X, which is only okay on airflow, with a overclocked 1080Ti and 8700k reach about mid 50's when gaming on 1080Ti and mid 60s on the CPU. In my case though the fan's on the rads are EK vardar's spin up to around 1200 RPM under load which for me is inaudible, mostly as usually doing something the speakers or headphones drown it out I suppose.

To be honest it could work in your build I expect, just need to accept that may need fan's to spin slightly slower if you want it quiet and see slightly warmer temps but well within the norm.
 
Thing is 2080Ti’s and 9900k’s for that matter produce a lot of heat under load under stock configuration.

If you stick a 2080Ti and say just bump it up to 2ghz and max the memory it will run maxed out at 100-130% power limit (330w).

If you are willing so sacrifice a small amount of performance for thermals and noise under any circumstance then it’s well worth undervolting both and it may still be possible.

I’ve done a lot of testing and you can get a 2080Ti down to around 60% tdp even with +1000 on the memory running at minimum voltage around 1750mhz. About 5% performance loss from max overclock but near on half the wattage.

Even at 2ghz it will do 1v steady so you can adjust and setup according to the kind of temps you want.

Same story with the 9900k. As long as you don’t plan on running it too hard then it should do well.

Does look a tight squeeze in that case, bigger is always better in terms of custom loop (if you can fit it). If that’s the kind of sizing you’re after then I think with the above points taken into consideration it should be ok.

Just ensure you get decent radiators and fans. Corsair ml120’s, noctua etc.
 
you don't need any new components apart from a bigger case. so maybe <£100 to resolve. A case like a Meshify C could take a 280mm in the front and a 240mm in the roof without issue.

It is a complete new build..

I only have 50mm gap on the side of the case which limits the size of the rad I can install in the case.
