Power surges (spikes, jumps) on graphics cards and weird fan behavior?

Have any of you encountered the problem of voltage surges on graphics cards? They appear randomly but regularly, several times a day.

I still have a question about HiveOS increasing the fan power for a moment, a few seconds, is this normal?

I noticed a strange thing. Graphics card temperatures are very dependent on the card’s location in the RIG. They have differences 12 degrees.

My setup:

4 x GTX1650
3 x RTX 3060 (2x MSI OC 1x Pegasus) all 1 fan
Bord: MSI B450 GAMING PLUS MAX (MS-7B86) MSI Bios ver. (H.70)
Ryzen 5 3600
2x PSU Corsair RM850W
8GB RAM
SSD 250GB

OC settings

GTX1650 +0 core +1300 memory PL 67W
RTX 3060 +0 core +1500 memory PL 140

Power setup
PSU no. 1 → 4 x reisers with GTX 1650 (67W) + Bord + Ryzen (120W)
PSU no. 2 → 3x reisers + cards RTX3060 (3 x 140W)

I have the same problem did u fix it?
