So I finally bit the bullet and upgraded my main editing rig to a 7950X for my freelance business. Ive been building my own machines for over a decade now but these new AM5 chips are honestly throwing me for a loop with how they behave. My logic was that my older 240mm AIO would be fine but man, as soon as I start a heavy render it just pegs at 95C and stays there. I know thats technically by design according to AMD but it still makes me nervous as hell watching those numbers.
I need to swap it out for something beefier by next weekend before my next big project starts. I was looking at the Arctic Liquid Freezer III since people rave about that offset mounting bracket for Ryzen but I heard it has some weird clearance issues with VRM heatsinks on some of the newer boards. Anyone tried it on an ASUS X670E specifically? I also checked out the DeepCool LT720 but then there was all that drama so now Im second guessing everything.
Im in the US so I can grab stuff from Amazon or Micro Center pretty quick. Budget is around 150-180 bucks. Im mostly worried about sustained thermal performance for 4K exports rather than just gaming spikes. Is a 360mm actually enough to keep these things from throttling or do I really need to try and cram a 420mm into my case...

Regarding that ASUS board, those VRM heatsinks are pretty tall, so be careful. TL;DR: prioritize fan static pressure for 4K renders. I might suggest the Phanteks Glacier One 360 T30 Gen2. Those T30 fans are 30mm thick and honestly beat everything else for sustained heat soak. Just double check your case clearance because the whole rad setup is almost 60mm deep.

youre right to be nervous even if amd says its fine. for heavy rendering on a 7950x, a 240mm just doesnt have the radiator surface area to keep up with the heat soak. i would suggest moving to at least a 360mm. be careful with the Arctic Liquid Freezer III 360 Black tho. the pump block is huge and it definitely clips the vrm heatsinks on some asus x670e boards. check your clearance measurements twice before pulling the trigger. if your case allows it, go for the Arctic Liquid Freezer III 420 instead. that extra radiator mass is basically required if you want to stay below the throttle point during long 4k exports. another solid option is the Lian Li Galahad II Trinity Performance 360. it has a much thicker radiator than most standard aio kits. just make sure you dont over-tighten the mounting screws. these am5 chips are sensitive to pressure distribution...
