Hello all, 
I've bought an OrangePi Zero Plus to use it as DNS/DHCP server with PiHole, and that's all I need from it. 
 
I have installed an heatsink and blacklisted the Wi-Fi module, but I still see it running with temperatures always around 69-70 C, which I believe is too high. 
CPU governor is set to "ondemand", and I see that CPU is running most of the times at the lowest possible frequency. 
 
Also CPU load is always very low... less than 5%. 
 
 
Any suggestion to reduce the temperature? 
 
Thanks a lot.
