Is Spiking CPU EDC and PPT normal?

Yesterday I changed my case and added 3 extra fans. I now have 3 fans per header (CPU & CHA & AIO) (all are set with mildly aggressive fan curve).

I'm not sure if i am going mad and i just never noticed it before or whether the case move/extra fans has caused this. When i launch Battlefield 5 for example or run a benchmark Ryzen Master shows EDC spikes up to 98% momentarily and PPT to 80-90%.

Question: 

Is this normal and i didn't notice it before?

is the 10C extra cooling i now get allowing more power to the CPU? (i.e not being throttled)

or have i maybe damaged something, or overloading MOBO with the changes?

Appreciate the advice 

I have not attempted any overclocking whatsoever

hello,

how have you installed the fans, front, top, rear, air flow suction/extraction ?

The airflow should be the same between suction and extraction if not you create the same phenomenon as in a forced convection oven.

Hello,

I have 2 at the top and 1 at the rear extracting, and 3 at the front sucking in. Temps are no problem whatsoever, i'm idling in the 20/30s. My question is about the EDC and PPT power spiking and whether that is related to the changes I've made or whether that is normal behavior

Thanks

Spikes occurs on all Ryzen depending on AMD Ryzen Power Plan, balanced or high perfs and chipset drivers version. Not worry about that.
