For my workstation water cooling project I plan on ordering some of these [18W fans](https://www.ebay.com/itm/174863685370) to mount to the radiator. I plan to test with PWM what output is optimal for the whole system.
I would like to see if it's really worth it to pay more for these heavy duty guys.
I figure since the bottle neck in any fan dependent cooling system is the air thermal conductivity then it should be advantageous to pass more airflow but I don't know at what point there is another limiting factor.
I want to get better metrics on this.
I've ordered a [360mm radiator](https://www.aliexpress.com/item/2251832789758141.html) for my budget Xeon workstation project.
What fans should I buy and how should I wire it to my motherboard which has two 4 pin fan connectors?
