Q: Fan more or less constantly at high speed

Hello!

 

I have a MBP Mid 2015 that is giving me a bit of a head ace. The fan speed is more or less running constantly at high speed if use web-browsers for anything else than text. If i scroll through a graphic-heavy website, not to mention watch videos on Youtube or other video-sites the fan revs up high enough so you'll think the computer is going to do a lift-off from the table.

 

I usually have three different browsers open. Safari for work-stuff, and Firefox, and Chrome for various other stuff. I also have two virtual systems running in VM Ware Fusion. One Windows-system and one OS X system. They can of course make the fans run in them selves at times when they do something a bit more cpu intense but usually they just idle.

 

First of all I want to know if this is normal behaviour. Personally i think it seems to be a bit too loud for a computer with this kind of processing power. There has been a bit of a problem with this system from the start, which lead to a motherboard-replacement. The system does not seem sluggish or slow at all. It's always very responsive which makes it seem that the CPU isn't under too much load.

 

I've got the following system, running 10.10.5

    Perform a SMC reset:

    If no success, look at this Apple support article:

     

    https://support.apple.com/en-us/HT203184

     

    Install a temperature/fanspeed application.

     

    Teat by closing all user applications and then open them one by one and see what the impact is.

     

    Set Activity Monitor to ALL PROCESSES and set CPU to display values from high to low.

     

    You may post images of Activity Monitor and the temperature/fanspeed application for review.

     

    Ciao.

    Tried the suggestion above. Used iStats to get a reading at the temp and fan. As you can see, the fan is running at fairly high speeds (it does go higher when the load is a bit higher). But the temperature is fairly cool. I wonder how it will sound if the CPU really gets to preform. I think I'm going to have to glue it to the table.

    And here's after running the screensaver for a few minutes (pictures from gallery. They are fairly big but still just pictures)

    Google Chrome and its parts, a known resource glutton among browsers, it using a lot of the resources.  What happens if you delete all of Google Chrome and its parts?  I use Firefox, Safari and Opera.

    I can try that of course, but at the same time, i think that a temperature at 59 degrees shouldn't make the fans rev to near max as they do. And if you look at the load, even though chrome is running, you can see that it isn't THAT much. So I'm still wondering if the behaviour really is normal for a computer like this.

    Ambient temperatures and the physical location of the MBP will also be factors in the temperatures that the MBP will reach.  You are also relying on the accuracy of the monitoring application that you are using to be accurate.  I have seen posts by users that Apple store genius bar technicians do not accept third party applications such as these in the determination if a MBP is operating normally or not.

     

    I would urge you to deleted Google Chrome and see what affect it has. if any.  Remember your MBP is under warranty and you always have the privilege to have Apple examine it if you suspect there are problems. They are the experts.

     

    Ciao.
