M3 nuts can be inserted to the bottom of the Top plate to more securely mount any height of 40mm High Power Fans that you deem necessary to blast your ESC. 🤣

NOTE-
I would advise to double check the length of your M3 screws (for your choice of 40mm fans) to make sure it's Not too long to where it may tap into the OEM shroud.

Here's the adapter installed onto an stock Spektrum Firma SMART 150A ESC.
The OEM 35mm internal fan has been removed ,but the shroud is retained.

Longer M3 screws are used (18 to 20mm length) which can reach the original Heatsink Mounting Holes/Bulkhead.
(You are Not screwing into the tiny fins.)

40mm Fans are bolted onto the Top plate-
(I'm thinking of offering a choice of enhanced fan shrouds to choose from.. I'm not sure if there's any interests.. Let me know.)

I would remove the Spektrum shroud's Fan Grill altogether. It just impedes/ disturbs airflow below the upgrade fan. Has no benefit leaving it there. Trim the OE shroud to remove it.
Nice mount. Awesome. :love:

Thank you sir.

Getting this little adaptor to fit exactly right... Took a lot longer than I expected.
Especially trying to achieve this ultra low profile.

You should see how many iterations I had to make to get here..

I hear what you're saying..
But, the OE shroud with that "circuit" looking grill actually doesn't impede all that much.
And, take a closer look at my adaptor.. I've designed in a beveled inner edge to provide more channeling of air from any upgraded 40mm fan that one may install.

Hopefully my little adaptor gives folks more options -to modify/enhance their ESC and still provide a way to return it to stock configuration ,when they want to.
