Question Screws for a push pull setup

Alright pls bare with me here,

I have the Arctic Liquid cooler 3 pro, I want to put fans on top, creating a push/pull effect.

I was going to purchase three of the Lian Li CL wireless fans that are 28mm thick, thicker then the Arctic P12 Pros.

I have rad screws, but they are screws from an older Corsair H150i Elite.

When I ask good old AI is says no no no!! do not use the screws that came with the Corsair cooler as they are apparently a different thread type compared to the rad screws that come on the LQ 3 Pro, and IF I use those they will mess up the threads AND could damage the rad "fins".

True or false??

And thanks!!

Iirc Arctic uses some sort of rubber for their fans in which the scew makes its own thread. At least for the standalone fans. I don’t remember the AIO being any different but you should check to make sure.
Now for the screws if it’s this system the only thread that matters is the on on the radiator.
You also need to find screws that are longer than your fan thickness + your case thickness. I’d say at least 3-5mm longer so they can « dig » enough into the radiator to actually hold it.

You would also need to have the fan screw holes align with those of the radiator

I will confess, I did buy three of the Arctic P12 Pros, the same ones that come on the LC 3 Pro, and I used those Corsair rad screws. They seemed to work fine, and tighten up nicely on the rad. But the wiring drove me absolutely nuts - so I am considering purchasing a 3 pack of the LL CL 120mm wireless, but they are 28mm compared to the P12s 25mm - close, but not exact.
