Heat increasing but fans don't spin (as they used to)

Hello,

I hope to prevent damage for others with this question and to understand the cause of the problem:

I recently recognized my MacBook turning very hot but without spinning it's fans anymore. This was running on Mavericks as well as El Capitan.

After installing Macs Fan Control they spin up now, so hardware is ok. This gives me the idea that it is related to planned obsolescence introduced via OSX.

Has anybody else experienced something similar?

Cheers,

Alex

How about doing some deeper diagnostics. I would pull the software solution you are using first so it doesn't mess things up. Next I would install this app as it offers a better view on what is happening here: TG Pro. Take a snapshot of the main screen and paste it here for us to see.

I'm sure we can help you figure out what's behind your problem.

Hello,

I have similar issue with my Macbook pro retina 13 2014:

despite high CPU usage, the fan spins constantly at 1300 RPM, which causes the CPU temperature raise up to 80C.

All temperature sensors seem to work fine and I can manually adjust fan speed as well as it can be changed by MFC.

Also i tried 3 different fans and the situation doesn't change.

I tried to reset SMC, pram and to reinstall the system (was cooling down CPU manually, don't ask how)

Atm i am using MacFanControl to regulate the speed of the fan, but the issue is still present and causing some discomfort, like i can't install new OS because MFC doesn't run during OS installation and i am afraid of overheating.

Despite all components look good, the system doesn't regulate the speed of the fan.

This happened after i heavily broke my macbook and tried to repair it by replacing its aluminium body, its broken screen assembly and its noisy fan (was a bit bended which caused noise).

It is interesting that after i disconnected touchpad the fan was speeding up normally when CPU temperature was raising. The downside of this was that macbook was constantly throttling , CPU usage was 300% and everything was very slow. I had the same symptoms when camera's cable was damaged.

Can anybody help me with this please?
