My problem was I had OHM 0.5B installed. Updated to 0.6b and that there was a lot more data in WMI under Root\OpenHardwareMonitor.
After updating to OHM 0.6b i restarted "Aqua Computer Service". After that temps were showing in aquasuite once again. Rebooting the computer would also do the trick if you don't know how to restart services.
Pic of data for OHM in WMI explorer. If you browse there and it's empty OHM is probably the problem.
You can download WMI explorer here

When you run it, select "Connect to host/namespace" under "Actions" and write "Root\OpenHardwareMonitor" in the Name Space box and click ok. After that, browse to "sensors" in the upper plane (classes) and select it.
You should see a lot of instances on the left and if you click one of them you should see the data (temps et.c.) on the right.
Hope it helps...
