I am having the same exact issue with my WD80EFAX-68KNBN0 with firmware 81.00A81.
For comparison;
1x Seagate Ironwolf 12TB ST12000VN0007: 29c idle
1x Seagate Ironwolf 8TB ST8000VN0022: 35c idle
2x Western Digital 8TB Red WD80EFAX-68LHPN0: 30c idle
1x Western Digital 8TB Red WD80EFAX-68KNBN0: 46c idle <— Not helium anymore?
I know these are rated for 60-65c, but right know my ambient temperature is very cool, around 58f. During the summer this would idle significantly hotter. I don’t even want to know how hot this would get during a raid rebuild. It’s a great space heater, but a horrible NAS drive. WD has made a mistake releasing this to market.
