Yeah. I got the same problem too.
I don't want to restart my computer every 6 hours.
Try to read through Eng forum seems no one can solve this problem.

same here. I using HWiNFO for grabing informations about temps, speeds, sensors etc.. and after 48 hours still no problem.

Chiming in to say I've had the same issue for going on a year here as well.

Both my D5 NEXT and QUADRO exhibit this at some random point after a few hours. Any software sensors refuse to load the data- regardless of if they originate from AIDA64, the Aquasuite Hardware Monitor, or over the Aquabus from the Aquaero. Restarting the service, Aquasuite, etc don't do anything. Only thing that brings them back is a reboot.

I've scoured the forums and gone through non-English posts using Google Translate, and I've seen this reported before. No actual solution has been offered throughout numerous versions of Aquasuite. Gotta say, this is kinda bad given that even the Aquabus doesn't work, and shared sensor data is pretty much the whole reason it exists.
