As far as direct heat from them, not entirely sure (I am sure someone with more experience can probably answer that).When the RPI5 is overclocked, should we place extra pads on the RAM and RP1? or do they not get hot even with overclocking the SoC?They don't get hot enough to need extra cooling.Perhaps the lack of thermal pads for these two chips might be intentional due to some sort of issue I am not aware of?
This brings me to my next question. Assuming that they don't get that hot even with overclocking; By placing thermal pads on them, could they get hot because of the heat transferred from SoC, PMIC and WIFI module via the heatsink?
However, as far as heat transferring across the board, I noticed that even the metal casing of the USB ports gets hot especially when running higher workloads on an both the stock clock speeds and overclocked pi 5 even with the active cooler cooling the different chips producing this heat (mainly the SoC), so there is definitely heat being transferred to the other components even if no thermal pads are attaching them to the main heat sink. So I wouldn’t suppose using extra thermal pads (which is what I have done) to “attach” the extra two chips to the active cooler, which it doesn’t “attach” to by default, would make a difference as far as transferring heat from the hotter chips to these colder chips, as that would’ve happened regardless considering the above.
And this “across the board” heat transfer isn’t even unique to the Pi 5 as it also happens to my Pi 4 (especially when I first got it before adding any sort of cooling system to it).
So from personal experience at least, I’d say it won’t make a difference as far as transferring heat from hotter chips to colder ones that wouldn’t have been attached with the pre-applied stock heat pads of the active cooler. As the heat would have transferred to them anyways through the board itself. And in theory, if the fan was running fast enough, the heat sink shouldn’t even get hot enough to the point it gets so heat soaked it ends up heating the other chips up.
But again, all of this is based on my own personal experience, someone more knowledgeable on the “theory” part of it could prove otherwise.
