But what about the heat sinks / fan when you mount the m2 on top? Especially /w Pi 5, to get more perf out of it, it presumably should have a sizeable heat sink

But what about the heat sinks / fan when you mount the m2 on top? Especially /w Pi 5, to get more perf out of it, it presumably should have a sizeable heat sink complete with the fan?
- distances 2y agoThe Active Cooler part (that contains a heatsink too) fits well under the HAT.
- jsheard 2y agoThe fan won't do much if there a second PCB stacked right on top of it though, unless there's cutouts for it.
- distances 2y agoIt does quite enough. Some test results are here: https://bret.dk/official-raspberry-pi-m-2-hat-review/#Temperatures-in-Official-Case https://bret.dk/official-raspberry-pi-m-2-hat-review/#Temper... And for any moderate use cases the need for any cooler at all could be disputed. I bet most RPi use cases don't include heavy computing.
- zamadatix 2y agoIn what way is thermally throttling at 86.5 C quite enough cooling? "Active Cooler in Case with HAT" idles near the same temperature "Active Cooler" reaches under max, unthrottled, load.
- distances 2y agoI think you misread the graph. "Active Cooler in Case with HAT" is pretty much the same temperature (74.8) as "Active Cooler" (no case, no hat, 70.6). None of the configurations with the cooler throttled.
- zamadatix 2y agoAh shit, you're 100% right. Looking at it on my computer monitor I think I was looking at the "Heatsink in Case with HAT" line color by mistake. My error and apologies!
- 0x073 2y agoA covered fan is not very clever and the rp5 need active cooling.
