The great debate: thermal paste application methods

For years, I was a die-hard 'pea in the center' guy for applying thermal paste on CPUs. I'd squeeze out that one little dot, plop the cooler on, and call it a day. It worked fine for most builds in my shop. Then, about two years ago, I started working on more high-end gaming rigs and compact builds. I noticed my temps were a bit higher than I liked on some chips, especially the bigger ones. I switched to the 'spread method' where I use a plastic card to get a super thin, even layer across the whole IHS. It takes an extra minute, but my temps dropped by about 3-5 degrees Celsius on average. I think the full coverage is key for modern, larger heat spreaders. But I've got a buddy who still swears by the pea method and says the spread just adds risk of air bubbles. Which camp are you in, and what made you pick a side?

You mentioned your temps dropping 3-5 degrees with the spread method, that's a solid win. I switched to spreading it thin too after seeing some uneven coverage on an old cooler I took off. Why risk a hot spot for the sake of saving one minute, right?

Yeah, that uneven coverage nancys90 mentioned is exactly why I switched to spreading it thin too. I'd rather spend the extra minute than risk cooking a chip over one dumb air bubble.
