2015 15" MBP fan noise watching Youtube

[kublaiboy]

Hi guys,

My 2015 15" MBP fan gets very noisy when watching Youtube. The fan returns to silence once I stop watching. Is it normal? Attached is the system profile screen shot.

Thanks.

Post CPU/GPU temperatures while watching YouTube

Here it is. Watch youtube full screen. Fan is loud.

I can't see any temperature readings, please run Intel Power Gadget while watching youtube

How can I get temp readings? Monit is the app I use.

Well, Monit is clearly not providing the data we need, I recommend to download "Intel Power Gadget" which should be able to provide exact temperatures of the CPU

I installed IPG, but when I run it, it says driver not loaded. what's going on?

Maybe do what it’s asking you to do?

It's fired up the Radeon GPU, that's probably why.

What browser? If it's not Safari, I suggest you try something that is Safari.

I tried. There's no Allow Intel App option. Did I miss anything?

Download gfxCardStatus, force integrated graphics only.

Downloaded and installed. I launched the app, nothing happens.

Check the menu bar.

Got it. But I can only switch from dynamic to discrete only. What does integrated do? how does it help with the fan noise? I'm not tech savvy. Sorry.

Yeah, you need to close all apps. Something is requesting high performance graphics (ie the AMD GPU) so it's locked the Integrated Only option out.

Integrated Only forces the Iris Pro graphics on the CPU to be used. It stops the AMD GPU powering up when an application requests high performance graphics - which is tripping the fans in. For low impact things like web browsing, watching movies etc the integrated is more than good enough. Just remember to flip it to dynamic switching when you plug an external display in, or try and run a game or app that really needs the AMD GPU.
