2 Fans spinning full speed, temperature sensors fine
== Ok so I have a a1278 MacBook Pro and the fan Is spinning at full speed. But it’s showing 0 rpm in macs fan control. And all,of the temperature sensors are fine. And i’ve done a smc reset and pram reset but nothing worked. I also replaced the fan that didn’t work either. So i’m pretty stumped right now

UPDATE 3/27/2019
I found the cause the fan spinning at full speed. The fan connector on the motherboard was loose so it may have not contacted the data pins. So I got cardboard cut it with an X-Acto knife and a small command strip that was cut then put it on top of the fan connector so it would wedge against the bottom metal plate. And it worked! Thanks for the tips though

What did you do before you noted the fan had failed?

Lets get a better view on whats happening. First remove MacsFanControl, then install this app TG Pro it allows you to see everything in better detail. Take a snapshot of the main window so we can see all of the sensors and the fan info (you may need to stretch the bottom a bit) and post it here for us to see iFixitでの質問に画像を追加する方法
