@W1zzard You should really use a k-type thermocouple thermometer and not a FLIR camera for measuring electronics temperatures. The FLIR can be affected by all types of emissivity and reflectivity issues with heatsinks and metals used in and around the component you're trying to measure.

Many techtubers I watch (like GN and Buildzoid) use Kapton tape to stick the thermocouple to the output leg of the choke on the back of the board. That'll give you a direct metal connection to the silicon inside the mosfets.

I want to see the performance difference between B350 and B450 when paired with an X series processor. Apparently this was one of the main reasons to be getting the 450..
So how come nobody has done a comparison?

I think its safe to say now that the days of FX with throttling or even catching fire on VRM`s are pretty much over now. The reason why this board is lasting is simply due to the fact that AMD wants minimum motherboard requirements for Mobo vendors. By this it means that all boards that are out there should be able to guarantee a bare minimum power delivery up to 125W or so. Many VRM`s and the used components can deliver way more then they are rated for. And even if you had a utterly high end board, the question would still remain with FIT these days in AMD CPU´s if you could even tap in all that offered power. Perhaps on a 16 core but i really doubt it.

Buying a high-end doesnt offer that much benefit apart from the futureset anymore.

This speaks to good CPU/Chipset design by AMD, and good power handling components used to build the Mainboard by ASUS.
