hehe about 3 weeks go i forgot to switch on my pump after turning on my PC.

ran it for almost half of the day

Exactly! Fans are used, which provide redundancy (apart from the water volume that in itself prevent a fast temperature increase in case of a total fan failure). If one of the radiator fans shuts down it's no big deal.
With air cooling there is typically only one fan for each CPU, which isn't redundant.

There aren't many completely passive server cooling solutions nowadays, are there?
As I wrote above; with a single moving component there's no redundancy, so all failures are critical ones.

Maintenance is my profession, and there are two types: Preventive and corrective.
Preventive maintenance is when you do pre-planned system tests and replace used parts before they break down.
Corrective maintenance is when you repair the system after it's broken down.

With air cooling preventive maintenance means cleaning the heat sinks once a year and replacing all fans before they break down, every three years or so.
Corrective maintenance means an emergency replacement of a broken fan, possibly together with an overheated CPU.

With water cooling (multiple fans and pumps) you need to check the water level, look for leaks, clean the radiator(s) once a year. Possibly replace the tubing every five years or so.
Corrective maintenence means replacing a fan or a pump when there's a lull in the server activity, giving the users time to prepare for the shutdown, if necessary.

Er....

So.... you are saying that water cooling need less maintainence. correct?

Hehehe...

I rather have just one possible failure than multiple chances of failure. Air cooling = just 1 fan per CPU.

Water cooling = pump(s), fan(s), tubing, connector leakage, metal corrosion.

Good luck doing your preventive and corrective maintenance.

Less emergency corrective maintenance, yes.
Overall maintenance might be a bit more, but it can be done in a more laid back, pre-planned manner.
