Doing some research and found a way to cool down the Pi

This experiment it doing OK.
The major issues with electronic hardware is the heat, and the thermodinamics. I've just fund a way to solve this. I'll be monitoring the Pi's temp, but right now it looks great at 99 F. cpu temp.PNG9.67 KBI remember the first time I installed the Pi and umbrel and it was so hot, that I unpluged everything, and start all over again without a case.
Not tried using Raspberry pi without case. However, found (1) active cooling by using a mini-fan running from the pi or (2) passive cooling by using an aluminum case as recommended by Umbrel are both good cooling solutions. My main concern is accumulation of dust on the raspberry pi if run without a case.
LN Node on Ras.Pi without any active or passive cooling is probably not best idea. Often there are bursts of processing load lasting moments to days (syncing). Normal rpi4 adapter is rated 5V/3A and of course every watt drawn from socket (up to 15W) have to go somewhere as heat.
Rpi motherboard on its own wont conduct as much heat to surrounding environment (closed plastic case will insulate board even more). After a temp threshold (80°C) chip start to underclock. Btw increased temp + rapid thermal cycling with changing load (10s of degrees up and down, due to miniscule thermal capacity of cpu without any heatsink) may adversely affect board longevity.
Yeah, I agree with all of you. I have a piece of metal like aluminum used in windows, and the Pi is facing towards a window, the window is facing north, so all wind and cold hit the Pi indirectly. It's been running nonstop since then, and the temp is about 36° C. And about removing a case, not, that was worst ever, that's when it hit 83° C that's a lot with the so called original Pi case. That case is the worst ever case for a Pi.
