Fan issues on late 2013 retina

[GigabitEthernet]

I've had fan issues with my late 2013 Retina for a few months now.

When using a virtual machine my fans ramp up to over 5000RPM, even Windows XP sitting on the desktop doing nothing but idling The same thing happens when using Chrome, particularly when watching video.

I've done an SMC reset and done a full, fresh reinstall of OS X and the issue still occurs.

What's going on?

Open your Activity monitor and see which process or processes are using your CPU. I imagine the VM and chrome are just using a lot of CPU cycles.

Yes VMWare is using 300% CPU and Chrome is using 100%.

- Then you don't have any fan issues. On the 15" I assume you have, that usage corresponds to 50 % utilisation of the CPU. It simply needs to cool down, so it revs up the fans.

Though it's never a bad idea to clean out some dust.

But 50% CPU utilisation when the VM isn't doing anything?

- Apparently. But that's a separate issue with the VM software, if it is an issue. The machine seems to be doing just what it's supposed to by cooling itself down.

What about the CPU utilisation when watching HTML5 video in Chrome (Amazon Video). Is that normal?

The VM is allowing a virtualisation it is "doing something". How much of your resources have you got assigned to your virtual machine?? I am assuming half your cores and half your ram, if you have assigned a small amount of you resources to your VM it will eat them up fast. If you want full resources assigned to both your OSes you'll want to install under boot camp and reboot into each individually for best performance.

Chrome is very poorly coded for OSX to avoid issues with browsing using all your system resources then use safari or alternatives.

Open up your VM and see what processes are eating up the CPU from inside
