Do you like half life sounds?
Boy do I have a new video for you 
Also, in this video: me changing from RAID5 of Many disks to single volumes for single disks. Who knows, Maybe I’ll do one storagenode to one disk also?

Old message but I just saw this. My particular CPU on the home server is a I7-13700K. (way overkill for just storj, but I do other stuff with it). However, that CPU can get HOT. the low key airflow from the cases low rpm 140mm fans wouldn’t be enough for the heatsink to keep it cool.
But have you tried?
The fan on the CPU does not teleport hot air outside, it still is getting dumped into the case, and then case fans still need to be able to displace it faster than it heats up. Otherwise, interior air heats up, the temperature difference between heatsink and inside air decreases, temperature rises… And if speeds are not matched – this creates disruption in airflow making things worse.
Your temperatures stay under control, therefore your case fans are sufficient. Removing CPU fan will result in slightly higher CPU temperature, due to less local airflow and hotter air around fins, but who cares as long as it’s under designed temperature.
To be clear, I’m talking about vertical heatsinks (with heat pipes and large surface area), not the puny default ones that intel ships in the box. In the latter case you might want to bodge an air duct from aluminum foil to concentrate air around the heatsink.
I mean… yeah. It doesn’t work (in a typical consumer case). I may not have had that exact CPU and cooler run fanless, but I’ve had other CPU’s run with no fans or broken fans (But still their heatsink) and the CPU’s get pegged at 100c and start throttling speed.
You can look up benchmark testing of noctua’s attempt at a fully passive heatsink the NH-P1. It’s huge, but it can’t keep up with higher power CPUs. it even allows for an optional fan mount.
Of course servers have ridiculous high speed fan walls running blasting air through every nook and cranny.

My current homemade NAS doesn’t seem to need a fan on the CPU, because it almost never turns on. Intel 9100t (TDP of 35W) with beQuiet’s Pure Rock 2 (don’t judge, it’s what was lying around unused anyway), a metric ton of case fans, and winter outside.
Photos linked in the original post also seem to use approximately half a kilogram of metal to radiate the heat away from CPU, so this might make sense.
Hooray for reuse! I have some 7-series Intel setups from 2017 that won’t die. They have enough RAM. They use SSDs. They have 10G NICs. Nothing wrong with them… they just aren’t sexy anymore 
My CPU fan was loud and annoying. I removed it from this sytem years ago and put a 120mm exhaust fan on the same header. It is reasonably close to the CPU cooler stack. It runs a little hotter but the system is quiet and has never throttled due to heat. Any CPU from the past ~20 years will throttle before it dies of heat anyway.
This is an old system I have running storj, with a SAS enclosure attached via PCI-e. In those days AMD CPUs were synonymous with excessive heat (high TDP).
- AMD Phenom II X4
- Hyper TX3 cooler (fan removed)
- Gigabyte 760G mobo
I’m wondering if you can reduce processor frequency and “undervolt” it heavily. Power consumption is proportional to frequency and square of voltage. You can easily decimate it on an old system from which you neither require nor expect high compute performance.
