Also, it looks like there's something up with SiaMining, wondering if that could be the cause of the fan speed? Pool hashrate dropped like a rock. I figured it could be due to some miners going to AntPool, since https://siastats.info/mining_pools.html shows about 300TH/s that I don't think was there before. But then I noticed my own hashrate had gone down. To rule out that being the result of me getting a spike in HW errors or something else happening like it resetting and spiking the fanspeed, all/many of the addresses here: https://siamining.com/addresses are also getting cut in half...as if I needed a reason to switch back to Luxor, it does seem like their luck issues are getting better.
