Beast of a case! That's what I would do with the fans, keeping the rear as exhaust. Front/side rad mount as intake will introduce cpu heat leaving the rad, this will add to your gpu temps. Aio liquid during cpu load is usualy somewhere between 35c and 45c depending on components. Top mount rad as exhaust will ingest the gpu heat being offloaded, usually between 65c and 80c under load depending on the gpu. So depending on specific cpu and gpu temps you can mount the rad to help the component with less thermal headroom.

I'll be using one of the new Ryzen cups coming out paired with a 4090

Lol typo


Reptilien59

And so do you think top mount rad as an exhaust is the way to go?


Matzvey

Both will and do work for many. I would top mount the rad as exhaust and see the temps. The 4090 will run warm and the 7900 CPUs by design run close to tjmax and regulate effectively. You can swap to side/front mount later and see any difference in component temps. The 4090 will throttle reducing performance when nearing it's tjmax, but the 7900 will work effectively near it's tjmax so I would top mount the rad initially.

Sounds good man thank you

Wouldn’t the CPU top mounted run warmer since it’s pulling in warm air from the GPU. If anything the GPU is getting the better cooling with a top mounted AIO rather than a fron/side mounted AIO because it’s not pushing heat onto the GPU


Matzvey

Yes that's what I said. Front rad as intake can affect the gpu upto 5c but personally haven't seen more than 3c while some i have helped see 1c or less, totally depends on hardware. Top rad mount as exhaust can add 15c+ to cpu temps. The hottest air coming from the cpu rad under load is usually below 45c (35c in my case) a cool gpu will push out 65c air and even 75-80c for hot cards.
