MacBook Pro fans running more/higher/louder on 10.11

I have a MBP early 2011 (i7 quadcore, 16 gb ram).

With Yosemite everything worked just fine, I generally couldn't even hear the fans, whatever the number of apps active.

Since El Capitan, the fans started spinning wildly and in Activity Monitor I noticed an insane CPU usage from Finder & Firefox, as you can see from the image attachement. What's wrong with this?

Thank you,

Can you list the root processes as well?

My mac mini has his fan bursting cause of notifyd daemon and powerd running high cpu.

It results in sluggish UI, slow system response, fan bursting.. El captain is the worst upgrade they've released so far...

No way, my root processes are very gentle, as you can see:

But my other processes are still running wild:

Any hint, anyone?

I'm seeing the exact same thing as Matt.Hias. Have the same Mac as you (rMBP mid 2012). Without an external monitor everything is fine, fans running at ~2K rpm silently. Almost immediately after connecting an external monitor (Dell 24"), GPU/Diode temperature rises from ~50°C to ~70°C, and after a couple of minutes fans rise to ~4K rpm and very loud, staying there until external monitor is disconnected.

Any idea?

Exact same thing here. I have updated to El Capital a couple of days ago and the fan is running really loud when I have my Dell 24" monitor connected.

Just upgraded to 10.11.1 and I'm witnessing the exact same behavior. The weird thing is that at work, where I connect to two external dell 24" monitors (total 3 screens), I don't witness the increased heat/fan speed. They are newer monitors tho, but I'm not sure that's related.

I have a mid 2012 15" retina MBP as well. The fans run all the time at max speed after upgrading to el capitan, under certain circumstances. After spending a few days troubleshooting this issue, these are my findings.

Fans run faster only when I connect an external display.

Fans run faster only when I set the external display to max resolution/Default for display which happens to be 1920x1200 in my case.

Fans are quiet if I select any other resolution (eg. 1600x1000). At this resolution, the fans do not come on no matter what I'm doing on the computer including a webex meeting, Skype or screen sharing.

I used "Macs Fan Control" App to monitor fan speeds. The GPU Diode & PECI GPU temperature seems to go up as soon as I choose the higher resolution on the external display and the fans gradually run faster and faster until they reach max speeds. They gradually slow down as soon as I decree the resolution.

I use my laptop primarily for work with a external display always connected. This is really annoying me. This never happened before el capitan. I upgraded from Mavericks.

I believe this problem has something to do with the resolution. At home I have a Dell 24" display with 1920x1200 resolution. The fans run really loud and the Macbook Pro becomes sluggish after a while. On the other hand, I have a Samsung 1080p monitor at work and I don't seem this problem happen at all.

I upgraded my Yosemite to El Capitan on my 2012 MBP Retina, the fan worked as before, default speed was still 2000 RPM.

Today after I did a clean install of El Capitan, the default fan speed changed to 4300 RPM.

No external monitor attached.
