M3 aux fan

I dug the M3 out of its garage spot over the weekend. I think the last time I drove it was last April (inspection sticker is from 8/19). Anyway, my daughter and I drove it around for a while and other than a dead battery it seems largely fine. I may have mentioned this here before, but for the past few years its had an issue where the aux fan runs constantly - makes the car sound sort of like a vacuum cleaner. They replaced the whole fan assembly last year and it seemed to be working fine at the time, but over the weekend (which wasn't particularly warm), the fan came on and stayed on after a few miles. Any idea here?

Thanks!
