I can't see the GPU temperature and FAN speed in Claymore (not just in v8, in older versions too). I also can't see or set any parameters in WattTool (and only see the GPU temperature and is jumping randomly between 0C and 1924761C). What could be the problem?

I use WIN 10, Catalyst 16.10.3, I have 6*RX470 and 6*RX480 rig, I get the same problem.
