Server is not getting hot

Water cooling is overkill for the lower clocked Xeons. These are the temperatures of my dual-Xeon workstation while idle.

Water cooling has no means to cool a CPU lower than room temperature.  (Unless the coolant itself is being refrigerated to a temperature lower than room temperature of course)  You said room temperature is 16.6'C, water or air cooling systems would be entirely unable to cool the CPU to anything less than 16.6'C, even if the computer was OFF, the cooling system could not bring the temperature below 16.6'C, otherwise would literally violate the laws of thermodynamics.

 

Your CPUs sensors must be out of calibration.  It's the only logical answer.

It would be lower than room temp due to the movement of air over the fins.  Movement of the air by the fans reduces the temperature of the air, in turn reducing the temp of the fins on the radiator which reduce the temp on the CPU?  It is a simple heat exchanger after all.

No, you clearly don't understand the basic physics of this.

 

Moving air, no matter how fast, is unable too cool anything to any temperature lower than the temperature of the air itself.  This is like pretty clear in the laws of thermodynamics.

 

A fan in a room of 20'C air, even if it blew air at a million miles an hour, could not cool anything below 20'C.  (Actually the wind resistance would cause HEATING by friction but anyway)

 

It's literally impossible.  You just don't understand how fans work.

You'll never go below ambient temperature regardless. Water is not magical, it stores heat. Cold is the lack of heat. If you want something to get colder, the heat has to go somewhere. If the object is 10c, and the air is 10c then where is the heat supposed to go? The temperature of objects seek to normalize / balance out.

 

Quick example with shit math... lets say your water is 20c and the air is 10c. Air blows over the radiator - the air goes from say 10c to 15c bringing the radiator down to 15c... now it's even.. so new air blows into the radiator at 10c and the air goes to 11c and the radiator now becomes 11c... you get the picture. The same exchange that's happening between the air and the radiator happens between the water and heat exchangers (radiator and CPU block).

 

That's the best I can explain it with my limited knowledge. To remove heat, it has to go somewhere and it seeks to balance out. It's like you got 2 glasses of water, you can pour from one to the other but you have to stop once they're at equal levels.
