There is another location on my MCM Gen2, in which these config files are also located. Maybe you can check if the /usr/local/modules/etc/wd/ directory exists on the EX2. If not, I would suggest first to look if the process wdtms is active on your EX2 by doing ps aux | grep "wdtms". On my MCM Gen 2 this daemon is running on /opt/wd/bin/wdtms with the parameter -config=/etc/wd/BMVZ-thermal.xml. So when you also have this wdtms daemon running, look for this config parameter and where it is located.
I have to point out, that my above mentioned approach needs a minor tweak: You have to make sure, that the value changed in line 59 (in my example changed to 37.0) can be reached after some time when the fan is running at 100%. So maybe don’t set it as low as I described in my example, otherwise the the drive_temperature_state won’t decrease and your fan will keep on increasing its rpm.
My suggested values per line would therefore be:
line 54: 61.0
line 55: 57.0
line 56: 53.0
line 57: 49.0
line 58: 45.0
line 59: 41.0
line 60: 1.0
line 61: 42.0
