Desirable pressure/airflow/wattage for radiator fans?
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.

No markation and IC is shaved. Want to use for radiator fans on my workstation water loop. ![](https://lemmygrad.ml/pictrs/image/6daa3fec-a461-4d4f-b3d7-1c12dfa8c76a.jpeg)

Workstation cooling system - what fan system should I use to cool radiator?
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?
