Had a weird issue with thermal paste application last week

I've always used the pea size method for CPU thermal paste. Last week I built a new system with an AMD 7600X and tried spreading it manually with a plastic card. Temps were running 8-10 degrees higher at idle compared to my old pea method builds. After three applications and re-seats I went back to the pea drop and it dropped right down to 35C idle. Has anyone else had similar results testing different paste application methods on these newer chips?

Spreading paste manually is always asking for trouble" - that line really hit home for me. I did the exact same thing with my 7600X last month and saw temps jump 6-7 degrees, it was driving me crazy. What I'm wondering is, did you try the line method across the chiplets? I've heard some guys swear by that for the X3D chips since the cores are off-center, but I chickened out and went back to pea before testing it. I'm just curious if the whole "spread it thin" crowd is running into the same issue on these newer sockets or if it's just a bad batch of paste or something.

Spreading paste manually is always asking for trouble, especially on these new AMD chips with their uneven IHS. The pea method works because the mounting pressure naturally squishes the paste to the perfect thickness every time. You learned the hard way, but at least you proved the old ways still hold up.
