Is it possible to immersively cool a device?

With reference to recent questions about overclocking (ie. What are the overclocking capabilities? ), is it possible to immersively cool the Raspi? Presumably such a system would have to rely on finding a coolant that is non-toxic, non-conducting,…

Raspberry Pi cooling; Blow cold air in or suck the hot air out?

I'm attaching a fan to the RPi's original case. I wanted to use a laptop cpu fan. Should I suck the hot air from RPi? or blow cold air inside the case? Btw, there's a heatsink on the Soc and LAN & USB chip.

does a heatsink for RPi3 processor needs to be exactly centered?

Does a heatsink for RPi 3 processor needs to be exactly centered ? It fell while I was "aiming" for the processor with the board in its case (I know, sloppy). Thankfully the thermal pasted heatsink landed quite well aligned on the Broadcom chip.…

Used within a Pi-Top Notebook, does the Raspberry Pi 3 B+ run cooler than the Pi 3 B?

I've been thinking about upgrading from a B to a B+, so I went and looked at the Raspbian Stretch with Desktop download I recently used to set up a new SD card for my Pi-Top running the Model B. It is in fact running the 2018-03-13 release. So if…

Heatsink too big

The passive cooling set I ordered has 1 big and 2 medium heatsinks. Would it do any harm if I used the medium heatsink for the capacitor? For the Raspberry Pi B+ it should have been 1 big, 1 medium and 1 small heatsink to fit perfectly.

Pi 5 fan header broke

My fan header broke off the board on my new canakit pi 5 max. It's an 8gb system used as a desktop. I have two questions as I consider returning the board. Is the passive cooling perhaps adequate? Is there an aftermarket fan system than I can hook…

Air cooling calculation?

How do I calculate the airflow needed to cool a RPi2 / 3 / 4? Assume "cool" means keeping the chip below a temperature where the Pi needs to throttle. Assume the chip is being stress tested, ambient temp is 20°C, no heatsinks. TIA
