Hi all (Dan),
I have a MacBook Pro 2015 13" which has a fan that won't run. I have...
Put a known good fan in
Replaced keyboard and trackpad cable
Replied thermal paste
New SSD
Fresh install
SMC and PRAM
I used 'mac fan controller' which worked, the fan was controllable up to full RPM and all of the RPMs in-between, but the Mac just won't control it. I assume a faulty LB?

@andyc7117 may be not a faulty logic board but a failed part in the fan circuitry. This could be related to an issue with either the Tach circuitry of the fan or the Fan Control circuitry. I would suggest that you start by checking the components and see what results you get.
Copy the image to your computer since there will be times where they may have to disappear ;-)
If nothing else, let's see your logic board. Maybe somebody on here can identify any issues with it. 在已经存在的问题里加入图片
这个答案有帮助吗？
Thank you. It's started working again after (another) fresh OS install.
