X3D doesn't run very hot, I don't have my new FC140 yet, but this is PA120. You should check your cooling

Because quick heavy CPU usage (opening a program, using a CPU-heavy feature in a program) causes temps to rise 20-25C , the fans were spinning up effectively doing nothing because the heat generated by the chip was still in the heatspreader until after the fans spun back down.

I see people say this quite a bit and I don't buy it I saw that with my old school air coolers, which are tuned for older CPUs. My old Thermalright coolers were awesome with 45nm + 32nm, did ok with 22nm, and struggled like yours with 7nm. These newer heatsinks are tuned for modern CPUs, I don't see any of those spikes that people talk about. Even with my 5900X no spikes, and I use top of the range power limits on my 5600X and 5900X.
