Fans not detected

Open aptonline opened this issue 4 years ago • 6 comments

So I've installed using your guide and EFI and its all working perfectly so thank you very much for all your effects 👍

My particular T460 has high fan usage and it ramps up under relatively low load, in windows I used a tool to reduce fan speeds and I thought I could do the same in macOS with other HWMonitor or Mac Fan Control but neither of these tools seem to detect the fan at all.

I noticed in your write up that you have power management working and I assumed this was also the same for fan detection. Is there something additional I need to do to get this working?

Thanks again.

Ok so after a bit of additional research it appears the that fans aren’t supported on laptops with VirtualSMC. This is a real shame as the hack is working perfectly with this repo but the fans are too aggressive and spin up constantly.

Is there anyway to manually ‘adjust’ fans from a config setting or SSDT file?

Potential but seeing as thought its posted in 2014 and not in English I might be struggling lol.

I'm run some checks on the hardware and nothing is coming back out of the ordinary. I've also monitored the temps and CPU via Intel Power Gadget. This is on idle.

Those temps don't look high, i've seen it reach 77 under load though. Wondering if a CPU re-paste would help? or even a fan replacement (it does whine).

Under load.

I would actually be quite interested in being able to control the fan. At least from an SSDT.

Fan is controlled by register HFSP.
