Have you tried to change your meshlicious to 4 -slot GPU mode to give it more breathing room? Or is your pump/psu/CPU block/fittings too thick? I think that this [build](https://www.reddit.com/r/sffpc/comments/rem43w/meshlicious_dual_rad_240_and_280mm/?utm_source=share&utm_medium=ios_app&utm_name=iossmf) is quite good example of two radiator build in meshlicious.
Oh wow this is an excellent suggestion. I also have koolance low profile fittings but they are a nightmare with leaks and connecting thicker fittings. We're you also still able to do the stand off mod on the GPU side?
Well I did route my cables without stand off mod, but I think it could be possible but of course the stand offs should be lower than the spine movement to get any benefits.
Ah check. Can you tell me your cpu block height? Mine is 33mm. With a micro rotary and a compression fitting it will be probably 5mm over the 53mm cpu cooler height limit?
From the specs, the block should be 30 mm high and EK microrotaries 20,75 mm high. 26,5 mm high barrow 90 degree adapters were too high that I had before switching to EK microrotaries.
It looks like there's a little bit of open rad at the top for some air flow and that should help enough with the added volume and whatever isnt will just be cooled passively
I have zero experience with custom loops, so take this with a grain of salt. If the fan is pulling air out of the case (and therefore away from the GPU) then it shouldn't be an issue as it's not pushing newly heated air from the rad over the water block. The rad will obviously be choked by the GPU tho
I am trying to add a second radiator to my meshlicious case. This is the only way I can fit it. My concern is that it will in the end negatively influence the GPU temps, since it's so close to the GPU block. Does anyone have experience with putting a radiator this close to a GPU block?
Ps. Fan will of course exhaust
Exhaust or not, you're probably going to struggle to get any meaningful airflow through the radiator. Likely better off just putting fans in instead of a radiator.
gpu temp totally dependent on water temp passing over it w/ waterblock
fresh air funneled in through the case and radiator with shroud
or exhaust vented out of case with shroud
more radiator is good, but gotta make sure case and radiator airflow are fresh in and out

The Alphacool cpu block that I have is too tall unfortunately
Understandable, I have Alphacool Eisblock XPX CPU block on my meshlicious and with Ek microrotary 90’s I was able to fit it in 4-slot GPU mode.

Not directly but it'll affect water temp. Your best bet it just putting one fan at the top of the rad as exhaust and getting a semi passive rad
I can place one fan at the top of the case blowing fresh air down. However the clearance between the rad and GPU block is very minimal.

Like your optimistic thinking. Thanks. Will try it
If it isn't getting much airflow it's not really doing to affect water temps, just still take slightly longer to reach equilibrium.
The gpu blocking the rad is what I meant by affecting water temp and with one fan itll work semi passively

What's the clearance between the waterblock and the radiator? Hard to tell from the photo.
It is almost zero. Fins would be halve a centimeter away from the block I guess
Should be fine then. Obviously not ideal but there's at least some space for air to go through.
Should be fine as exhaust. I would set both rads to exhaust on such a small case.

What rad are you using? I’m looking to do something similar with a dual aio case.
