I have a pi4 running PiHole fitted with a PoE+ hat with a fan. It gets a bit irritating on the lower speed so I've been playing with the settings. What is everyone's opinion on temp for these things? I know it starts to throttle at 80.
My rpi4 that runs Grafana and influxdb normally hovers between 50-60C, with a room temp 18-22. The rpi is housed in a flirc case, with no active cooling.

This is the way! I use Flirc cases for all my RPis

I had it in a flirc case but then I had to change it when I added the PoE hat. It hovers around 60 to 70 now with the fan settings being very relaxed. Perhaps I need to suck it up and deal with the fan being on more and lower the temps.
Yeah I'd feel a little uneasy with it running so high.

Yeah, I just checked the board physically and it was HOT. Yikes! Made some adjustments.....

First the pie is designed to work up to 80c so technically as long as you dont hit that constantly it should be good long term. I know we are all thought to think heat is bad, and it is but design of processors have been made to tolerate allot more in recent years.
I have used flirc cases, argon one cases, an acrylic case with a fan, and juat air cooled it. The flirc is the only fully passive option while the argon one is a kind of hybrid approach. If you aren't able to be fully passive air movement is your friend. I went as far as getting a big 120mm fan and just using that to pull air past the pie. It doesn't take much to make a big difference.

Yes, that won't help cool down the board 
. This should do what we need, unless you are wearing a hat....
