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.

For others who find this post: I had the same issue (after doing a hotend swap), I attempted the fan test calibration to make sure I didn't mess anything up and the test started failing (yet both fans running/working). Rather than trying to dissemble anything, I took a small portable vacuum and had it running/sucking close to the exhaust port of the failing fan. Ran the check with the vacuum running and it passed the test. ***Disclaimers: some types of fans when ran 'externally' will produce voltage, which might or might not damage any connected circuitry. Attempt this at your own risk. I minimized the chances by not having the vacuum directly coupled to the exhaust shroud and I only started the vacuum after the fan was running (to assist it getting to whatever speed the test wanted).
