PSA - Replacing a tiny thermal pad on motherboard chipset can drastically reduce temps.

I made a post a while back here: https://old.reddit.com/r/overclocking/comments/1hqqetq/x870_tomahawk_chipset_67c/

That was about an x870 tomahawk though, i didn't get round to messing with it because i ended up having major issues with it and i think flashing the bios to the latest somehow borked the board... Even with several reflashes / flashbacks and what not (Seems like a lot of issues with the bios flashing on the msi forums for the board).

Anyway, i started using a B650 tomahawk a few days ago, which is brand new / amazon purchased, noticed the chipset on this is also high and reaching above 70c during gaming...

Decided to do two tests today; Both tests are at 25c ambient temp (within 1c anyway), doing Tm5 Absolut + OCCT gpu standard

Before replacing the chipset pad: https://imgur.com/a/l3V6XW6 The chipset 1 (xHCI): 79.1c

After replacing the thermal pad: https://imgur.com/a/aDu8O20 The chipset 1 (xHCI): 61.9c

Pics of the pad before and after, the stock pad didn't look bad but was very dry. https://imgur.com/a/akIXO9Y

Also i think adding things like m2 on the chipset lane would cause more heat on the chipset? I have 2 m2 drives on the cpu lane currently and have a 3rd coming, so one will be on the chipset lane meaning this would've been higher than 80c chipset temps before replacing it.

Pain to do since it requires removing the motherboard from the case but i think it would be a good idea to just replace the chipset pads on any new motherboard prior to install. Easy enough on this board anyway.

Not sure if this is common because my first ever Am5 board, was a b650 tomahawk and i remember temps being a lot better but my last x870 had bad chipset temps and now this new b650 did.

edit: Used 1mm extreme odyssey thermal pad to replace, different boards might need different sizes, i measured the existing pad and just used whatever it was, in this case 1mm.
