PDHanumanSvr causing my system fan to go off
Reply to this topic
[Post New]
Hello,

I have a long video clip that was previously loaded into PD365. I believe I used the pre cut fxn on it.

I started a new project, and upon loading it my HD went nuts and the fan get going on an off.

Checked the cput temp and it shoots up to 95 and stays there. This made me uncomfortable so I shut PD365 down

Before I did, I checked Task Manager and it was the PDHanumanSvr Application service and it said power usage was Very High
I read this service creates shadowfiles, but will it do that for all files, or just previously pre cut files? Can I load a file with out the pre cut again?

Another file I loaded same size, and previously pre cut - upon load it gets hot, but the fan does not go off. Strage.

Suggestions on what to do?

PDHanumansvr is indeed converting all your clips loaded in your media room into smaller clips that can more easily be handled by PD. The result of the conversion remains in the folder ShowdowEditFiles until the retention period (as set in preferences) is passed, or until you (manually) delete the shadow files using the button in preferences, general to that effect. (Or delete the files directly in the (Windows) folder.)
Files in the media-room that have not been converted yet, show a little yellow icon in the left-hand bottom corner. Files that have been handled show a green icon.
Note that the shadow files may take considerable space on your disk depending on the editing work done and at hand.
I don’t think there is a difference in handling pre-cut files is regular clips.
The program indeed takes all the (CPU) power it can get, and the temperature can be high and the fans can make noise. Also obviously depending on the power available in your system. What I see in my systems is, that PDHanumansvr in most occasions modestly steps aside when another application needs CPU time.
I don’t think that changing the shadow file to a lower format will help, because it still requires conversion power. Turning the shadow file creation off, will help, but will also put an extra burden on your system while editing. You might see the editing work slowed down depending on the power of your system.
So far, apart from the fan sound, I have not seen any problems with this process. If it troubles you, you can of course change the settings to not make shadow files, or save the project and close PD for a while. Upon the start and loading of the project (and with the shadow files still in place) it will restart the conversion process where it left off).
The good thing is that converted files are there available for a bit smoother editing in PD.
So, there may be things you can do to minimize the overload. Or you may want to have look at the load of your system, when you do the PD editing, or look at whether the capacity of your system is suitable enough for the editing work you do.

Warry answered the question well. Out of curiosity, I enabled shadow files and checked CPU utilization, power, and thermals while they were generating. It’s 19% at 4.6 Ghz on this particular desktop. See the screenshot.

The CPU fan should not stop on a modern CPU that is throttling between 95 to 100 degrees Celsius. A laptop CPU may be power limited to say 15 to 45 watts by throttling. I Would like the OP to post a DxDiag.txt of the pc in question. This will allow users to determine if it is a laptop that may still be under factory warranty.

Probably something amiss here, 19% CPU is way underestimated. Issue could be too rapid of snapshot at start of shadow file process as windows uses a time averaging approach. Inconsistency also evident as HWMonitor shows 74% CPU utilization.

Good catch Jeff. The task manager was paused to end task on Windows Explorer that is locked up. Just duplicated it. CPU utilization is 92% on the task manager and less on HW Monitor. See the new screenshot for Shadow files generating.

Not really less on HW Monitor as you note. Task Manager reports on base clock, you are operating in TurboBoost mode. So 0.92X3.5=3.22GHz of clock effort going to current tasks. HW Monitor reports on Turbo'd speed, 70% at 4.6, so 0.70X4.6=3.22GHz of effort, so really the same stats, just presented differently.

But any laptop hitting close to 90+% of base clock sustained load will ramp up cooling fan speed, Veepo experience nothing unusual.
