Primary card i can understand to fix remote access resolution, but why the hell would you doend 6x 15 bucks when u dont need to, how can the shown temps be wrong?
On Windows 10 running the latest ATI drivers and RX470's, they don't report their temps to the OS (using OpenHardwareMonitor, but Claymore seems to get them) - but the larger issue is that the fan control doesn't seem to work. I normally have claymore set to have them at 80%, but I literally will see the fans not spinning, then plug in the dongle and they start spinning. Plus with the dongle, then the temps show up even if the video output is disabled... My systems with Nvidia cards have no problem just having the one dongle for the whole system... For me it's more important to have everything being monitored than save a couple bucks, so I put them on all the cards just to be sure. If at some point I don't need them, I can easily just use them individually on systems.
