Environment/Setup :

For the Primary Pi-Hole, I’m running that on a Small Form Factor Computer with Ubuntu. It also runs Unbound + Samba server, RustDesk but nothing else.

For the Secondary Pi-Hole, I’m running that on a Pi 3 B+ [with no heat sink or fan] . This one has no Unbound. but has VNC + RustDesk running .

Ratio of Queries / load when comparing Primary vs Secondary :

I’m seeing, on average , the ratio of queries serviced by Primary : Secondary is 100 : ~55 (71K vs 41K) .

Question 1 : Is this ratio of Queries for Primary vs Secondary normal /expected ?

Another interesting observation : The % of Query Blocked are on par (27% vs 23%) especially when considering the AdList Domains for the Primary is 2x the Secondary

Temperature of Pi running Pi Hole

Another interesting aspect as well is that as Pi-Hole dashboard publishes temps ;

the stablised running Temp of the Primary is at ~27C/80F

whereas the stablised running Temp of the Secondary (Pi ) is ~65C/150F

The rooms ambiant temp is 22C/72F , so another way of looking at it is Primary is [Ambiant + 5C ] and Secondary is [Ambiant+35 ]

Question 2 : Can you share your similar observations and if this normal ? I really like the idea that the Pi is super energy efficent , running off USB, but 65C is pretty warm and a little concerning!

PS: I’m in the Southern Hemisphere and we are just starting Summer and the ambiant temps can reach 40+ during the peak periods or days

PPS: suspending the RustDesk task doesn’t make any difference

Thank you
