edit 2: He has bought the air cooler!
He will be running the 9800X3D, which I don’t think gets hot enough to require an AIO. We are choosing between Arctic Liquid Freezer III 360 (AIO) and the Peerless Assassin 120 (air cooler)
Benefits of choosing an AIO (Arctic Liquid Freezer III) is better temperatures, nicer aesthetic. Downside of going with AIO is the possibility that it will leak/wear out over time, shorter lifespan compared to air cooler (which can pretty much last forever)
He will be getting a Lian Li case (the O11 Vision Compact) with the RGB fans set, meaning he could go with the cheaper 5 fan set instead of 8 if he decides on AIO. Combined with a decent sale on the AIO in my region, the price difference isn’t that large.
What do you guys think?
edit: Mmm the internet people seem to disagree with each other
Rule of thumb is to use the tdp and at least try to cover that with the thermal rating. 120w is your tdp and that is either a beefy air cooler or a multifan aio. These cpus do run hot but it’s by design to some extent. My tdp is 150 in the same series with a rating of 170 on the aio. Still goes up to 90 when stressed.
