MacPro7,1 mystery fan? #573

Closed robohack closed 2 years ago

robohack commented 2 years ago

This is probably going to sound silly and there's probably nothing wrong with Macs Fan Control, but I hope someone here can give me some clues as to what I'm experiencing.

So I have a new (to me, it's a refurb) 2019 MacPro (7,1) now and I've installed Macs Fan Control even though I wasn't expecting to have to use it (like I did on my ancient iMac 27-inch).

However there seems to be a mystery fan not being reported or controllable!

When I play a high-res (e.g. 4k) movie on YouTube, and occasionally for short bursts when I start some other high-CPU programs, I hear a fan quickly spin up to quite a high rate.

However Macs Fan Control doesn't show any appreciable change of speed in any of the four listed fans.

I also have iStat Menus installed, and it also only reports the same four fans, and its history graphs show no speed changes in any of those four fans at the times when I can clearly hear some loud obnoxious fan running.

So does Macs Fan Control iterate over all the fans reported by the SMC, or does it assume some fixed number based on the machine model? Do I have to disassemble my new machine to find this mystery fan?

There are only 4 fans I believe.

Do I have to disassemble my new machine to find this mystery fan?

It will not turn on when the housing is not closed.

Never heard of this issue before, please let me know if you discover something about it.

robohack commented 2 years ago

I've not yet opened the machine to check, but I am now reasonably certain that the mystery fan is directly on the AMD Radeon Pro W5700X card. I happened upon a web page that drives the GPU up to over 30% utilization (with iStat Menus showing both GPU die temp sensors rising and holding above 50℃), and when that happens this mystery fan runs fast, loud, and continuously.

There's nothing to "fix" with the app, unfortunately.

robohack commented 2 years ago

OK, thanks for having a look!

If I ever manage to find some way to read the fan speed from the graphics card I'll try to let you know.
