Is a 140mm cooler always better than a 120mm cooler (or atleast not the high ends)?
Is a dual tower always better than a 140mm cooler?
What territory of cooler should I look after if I just want to run my 5 3600 cool enough to never thermal throttle (possibly with minor oc).
All of these questions can be answered in the following way: it depends. When it comes to cooling, there's typically two primary concerns: how hot the processor is when its doing something and how loud you can tolerate it to be. A 140mm cooler with a fan that's moving slow all the time may be great for low noise, but not so much for temperature compared to a 120mm cooler that's allowed to ramp up the fan speed. And if the processor is low power to begin with, a dual tower cooler doesn't have a lot of value over a 140mm or even a 120mm cooler, even if it technically keeps the processor cooler.
On another note, thermal throttling is when the processor is unable to keep base clock speeds when doing a workload. Even the stock cooler that AMD's processors come with can do this. If you want the processor to maintain boost clock speeds for extended periods of time, then investing in a better cooler will certainly help.
So with that out of the way, what should you get? Unfortunately the old metric of using TDP doesn't work anymore since Intel and AMD measure it differently and coolers likely default to Intel if they don't specifically say. But for a lower power part like the Ryzen 5 3600, any decent 120mm cooler will do. Heck I'd wager a 90-92mm cooler is fine too, but I advise against it due to the scarcity of finding decent fans in that size.
