Hello I'm using Ryzen 7 1800x for doing rendering works.
Although I'm using a single radiator fan ThermalTake liquid cooling , my temperature rises to 90 degree and crashes after 2 mins of usage and its very daunting to choose which watercooler can do the job right :/
My personal preference is to do a custom water loop, not all-in-one coolers. If that's not practical, then get a good air cooler. It will generally be about as good as the AIO, and at the same price point, actually quite a bit better.
