I want to mount the Bionix P140 on my AIO radiator, but the screws don't fit. What am I doing wrong?

If you want to replace the fans of a compact water cooling system from a third-party manufacturer with the ARCTIC Bionix P140, it is possible that the pre-assembled screws may not fit. Compatible screws are available from ARCTIC support. To request these, please send an inquiry with the attached invoice for the P-fans to: cs@support.arctic.ac
