Keeping the RPi cool does make a difference

Naturally cooled Pi 4 - No temperature issues.

Did your neighbor trim their trees?

If only it were that simple - That particular receiver is remotely mounted, on top of a Martello Tower. It has a clear view in all directions.

I’m surprised you haven’t taken it down to have a look.

Scroll back up to post 51 - We replaced it with a Pimoroni fan shim and it’s much better.

I used to use them, they do a good job.

I used a old pc chipset cooler on my pi4 and the temps really dropped and never really go above 35c



With that much heat-pipe (and fins), does it even need the fan?


I love it, that’s excellent.

/edit - How is it mounted?

is just there with a little thermo paste seems solid and has been on there for a long time,

I had a power cut the other day and the fan didn’t start back up and this was the difference in temps, you can see when i started the fan up again system-localhost-temperature-7d

im running the fan off the pins so only 5v but the fan is 12v so doesn’t always start on its own

All my Pi’s are running at 50+ °C for several years without any issue.

Pi #1(RPi Model 2): No heat sink, no fan, in plastic case.

Pi #2 (Orange Pi PC): No heat sink, no fan, in plastic case.

Pi #3 (RPi Model 4): small heat sink, no fan, no case.

RPi model 4

@abcd567 i was getting throttling as mine was getting to hot without a case, its in the loft but it does get really hot up there, was looking at cases but found this old cooler and tried it and worked a treat. I had a pi zero before which was fine

Yes, temprature depends where and how you install the Pi.

All my Pi’s are indoor, on floor in living & study rooms, a very good condition ambient temprature wise.

Others who install Pi in attic or loft or on roof/mast, exposed to direct sunlight, have to provide means of additional cooling.

Outdoor enclosure. Fan from an old Radeon graphics card. 5v USB powered. Perfect size for the Pi.


Looks like you live in the desert like I do judging by the soil, rock and daily spikes. Tough to keep anything cool when there have been 145+ days now being 100f (~38c) or above this year. :woozy_face:

I grabbed one of these for my next enclosure build:
