It has to run at 60 degrees Celsius at full speed to maintain longevity, that might not be important for electronics that will have more performant replacements later, but with 1Gflops/watt 32-bit operation the raspberry 4 is peak humanity performance/watt/memory/longevity/simplicity/size/weight/$ (smaller lithography might actually reduce lifespan) so it needs to kept at a cool and silent TDP usage by design, specially since the form-factor has non standard heat-sink attachment. Fans are not a long term solution to anything and that is what makes the raspberry 4 really valuable; namely it's on the limit of what _can_ be cooled enough passively without adding too much weight/size! I'm all in on the standard raspberry 4 for server clusters and gaming clients for my 3D MMO that I'm writing from scratch! Sad that the mounting (plastic is not long-term, the SO-DIMM was better in that regard) and form-factor of these are a bit odd, we'll have to wait and see if someone makes boards/heat-sinks for it! They need to be compact even when stacked like these: http://move.rupy.se/file/pi_4.jpg http://move.rupy.se/file/pi_4.jpg The home computer revolution started with the C64 and peaked with the raspberry pi 4, everything in-between has just been revenue landfill.
