Found out my thermal paste application method was probably wrong for 6 years

Ran across an old Gamers Nexus video from 2023. They tested pea vs line vs spread methods for thermal paste. Turns out the line method works better for most CPUs. I always did the pea method. Over 100 builds. My temps on a Ryzen 5 3600 dropped 4 degrees after I switched. That's 6 years of potentially higher temps for nothing. Makes me wonder how many other accepted "rules" in this trade are based on outdated data. Is the pea method still the standard for a reason, or are we all just repeating what we heard in 2016?

The other thing nobody talks about is how your mounting pressure and cooler base flatness can totally override whatever paste method you use. I had a friend with a janky AM4 bracket that was slightly crooked, the pea method actually helped because it compensated for the uneven pressure. Once he fixed the mount, line method worked better. So the "best" method depends on your specific setup, not just a universal rule from a video.

Yeah, the "pea method is best" thing got drilled into my head back in like 2017 from a bunch of Buildapc posts. I was dead set on it for years too. After seeing that same Gamers Nexus video though, I tried the line method on my 5600X and it dropped temps by a couple degrees under load. Makes you wonder how many other "best practices" are just old advice that stuck.

That's the thing about "best practices" in general. Once something gets repeated enough by people who sound like they know what they're talking about, it just becomes fact. I see the same thing with cooking where everyone swears you have to rinse your rice until the water runs clear, but then you watch some actual Chinese chefs and they barely rinse it at all because they want the starch. @sean_barnes24 is right about the hardware being the real variable too. People treat thermal paste like it's magic when half the time it's just bad mounting pressure or an uneven cooler base doing the work. Feels like most of these "rules" are just copy-pasted from the first forum thread that got popular.
