Noticing upon Mac shutdown, my P32 R6 smaller fan continues to run continously after all power off. 

Powering the physical unit off prior to shutdown doesn't casue the same issue, it's only through computer shutdown.  Connected through Thunderbolt 3.  Firmware up to date as of 19/7/2020. 

Any thoughts on how to resolve?

Hi Tony,

We need to verify the report to find the issue, so could you reach us through support.promise.com and create a web support where you can attach the subsystem report.

Hi Tony,

 

Did you ever fix this?

I have the same problem and I have contacted support and they deny it's a problem.

Thanks

Stu

Hi, same thing happens to my new Promise 32 I just purchased from Apple.com.  The powersupply fan remains on.  Should I return this to Apple?  This unit is 1 week old.  thanks

 Hi Stu & W Ko...

Nope, never did resolve this, and now starting to see further forum members experiencing the same issue.  After working with Suppport some time ago, issue was deemed as normal, and they marked it as solved.  Seems that on Mac OS, the P32 R6 sees power off as 'sleep' - unlike any other connected device!! - and the small fan will run continually.  My only workaround has been an eject and manual power off everytime I shut down.  Daisy chaining through other T3 devices also doesn't function as advertised - with irregular power cycling issues, sometimes during read/write... this unit makes me nervious, and my only stable assurance is direct connection to main device, and eject and manual power shutdown.  I still hope an updated firmware may improve the situation someday.

Older Pegasus models have only one fan and they will go OFF when the unit is put to sleep. 

Pegasus 32 models have 2 fans in them . Here is how they work.

1. When the Mac is asleep, and Pegasus is asleep, the big fan rests, and the small fan runs. Pegasus will wake up when Mac wakes up.

2. When the shut down button or the power button is used, Pegasus powers off, both big and small fan rest. Pegasus will not wake up automatically. It will have to be restarted.
