Got a 25L recently and ran it for a few weeks, everything was fine except the when the system resumes from sleep, the CPU fan would run very slowly, this only happens if the system went into sleep in the first place. If I were to soft reboot, the CPU fan remains running slowly, but everything is back to normal once hard reboot.
Decided to run diagnostic on reboot, FAN SPEED passed, but FAN THERMAL CONTROL failed. Had the system exchanged, replacement was running fine, in/out sleep causes zero issue with CPU fan. Decided to run FAN THERMAL TEST on replacement and it came back as failed (Failure ID 9LV9XV-A6PA7M-QF8U3G-J69903). BTW, the CPU fan is fine, even swapped out another fan to test.
In short, everything is solid now except the failed thermal diagnostic test. Just wish to confirm if the test has a glitch since it's very unlikely 2 units exhibited similar behavior. Thanks.

Praveen, thanks for the walk-thru. I actually submitted a ticket thru chat yesterday. While it is possible that 3 units of different production batches could have the same failure, it is nevertheless highly unlikely. I have not experienced thermal shutdown and tested the CPU fan outside the system, and can confirm it is performing in range. I also substituted a known good fan and it also failed the same test. I tend to lean towards a faulty test code ATM.
Truth be told, the airflow, or lack thereof, in the 25L is inexcusable, HP should have gotten smarter with the Obelisk case as it is essentially the same case. I know, HP's solution was to bring out an improved 30L case with added front intake but continue to sell off units using the Obelisk/25L case.
Hopefully the ticket will help. Thanks. BTW, I am only looking for answers to the FAN THERMAL TEST, the CPU fan itself is running fine, even when resuming from SLEEP.

I understand your concern and I have brought your issue to the attention of an appropriate team within HP.
They will likely request information from you in order to look up your case details or product serial number.
Please look for a private message from an identified HP contact.
Additionally, keep in mind not to publicly post personal information (serial numbers and case details).
