It wont fit, the smallest size fan Noctua makes is 40mm and EVGA uses 30mm fans.  If the noise it too much you can lower them to like 20-25% and you should be ok if your VRMs have good airflow.  The single one on my X299 FTW is set to 20% (~2000 rpm) and the VRM stays in the 40's on a all core 4.6 OC on my i9-10920x and I never hear it unless the BIOS bug happens on a cold boot and it ignores my setting until I reboot.

If you are fixed on doing that, you can rescale a 3D model of a Noctua fan. You might need to adjust the hub and 3D print or ask someone to print find a website that can print and send it to your home. Wouldn't recommend that though as it's just too much for too little.
The wacky solution is; you can just rip the old fan from it's place and super glue a bigger noctua fan on the heatsink.

Thanks. Were just curious because I came by the mini Noctua fan while searching for other stuffs, and thinking it could be nice to replace :)
