XL fails print fan RPM test after upgrade to 5.1.2

Upgraded to 5.1.2 and it said to re-run calibration tests.  First test failed print fan RPM test.  I can see both the print fan and hotend fan spin up during the test.  I can feel air blowing out from under the hotend.

I have the same issue. I updated to 5.1.2 and then started to receive the same 'fan RPM test' failure during the Self Test.

Removing the shroud for the print fan fixed the issue.  Thank you.
