    Hi

    I own a Mac mini late 2012. Lately the device shows strange behavior. Sometimes the fan goes mad. I added a Crucial SSD. It still has the initial HDD too. The further specs are late mini 2012, 2.3 i7, 16 GB ram.

    Sometimes the fan is like really quiet. Then suddenly the fan goes wild. It keeps on blowing for a while. Then the fan goes quiet again. I do not know why this is happening.

    I added nine screenshots of activity monitor.
    At the first three the fan is quiet.
    The second batch the fan spins louder.
    The third batch the fan goes wild.

    Does anyone know what's happening? It happens on youtube, facebook and also playing Nox (android simulator). In the screenshots facebook is not activated.

    Thanks for your answer.

    It could be a whole host of things. When you had the machine open, did you clean the fans?

    Is the fan working like it should?
    By that, I ask if you have used an app that allows you to monitor the temps in your mini. Maybe it is just heating up, kicking up the fan. It runs for a bit, cools down, and the fan goes back to idle.
    Try running a temp monitor app, such as Macs Fan Control - or
    smcFanControl

    Here you go. It is going crazy again. I took a screenshot.

    It seems to be the Nox player. The second I turn it off the CPU temperature drops immediately.

    I read through it but many of them seem to state that 100° C is acceptable. I however do not like this. I must admit when I close the emulator the temperature is like 80° C. Fans do not make any sound.

    My mini has pretty decent specs. Would I get the same temperatures and fan going wild with a new device? It cannot be the OS because I just reinstalled it.

    The emulator is taxing the CPU heavily (you have a headless Virtualbox instance running). The fan is working as it should.

    Would the emulator tax a new device as much? My mini still got a 2.3 i7. Seems pretty decent. Could be because it does not have a distinct GPU though.

    Yes, it will. What you’re seeing is not a malfunction in any way.

    I understand. I find it troubling though the fan spins so hard to play a simple android game. Hence I wondered if a new device could solve this issue. Do not get me wrong the fan must spin hard now as the temperature is high. I just wonder if the temperature would get as high on a new device.

    But it's not just a simple game; the Mac has to create an entire emulated Android environment. That's a complex computing task.
