Hi MacRumors,

I just bought the new MBK 2019 8 core with VEGA 20 graphics.
Occasionally i use it for gaming, Dota & World of Warcraft.

It runs great and i love the graphics i am able to use now.

However i am having problems with the fans running at max 6000 RPM, causing ALOT of noise.
.. I downloaded an app to monitor and control the fans, during my last game of Dota i manually put them to 4000 RPM constantly and it kept the CPU & GPU steady at 70 degrees.

- How hot can the GPU & CPU run and still be safe?
- Is there any other solution to this fan noise problem than controlling the fans manually while gaming?

Disable turbo boost, 2.3 or 2.4 will still be plenty for gaming, enable Vsync and reduce graphics details/resolution until the Vega runs way below 50W. Keep both fans at 4k, or if you don't mind the heat keep them in auto. The CPU and GPU will throttle before reaching dangerous temperatures so don't worry about it, just set it up for your own comfort.

Thanks, I'll give that a try.
Both games should be fine, as i dont believe they are very demanding in terms of graphics - they ran just fine on my previous MacBook pro 2012.

- Where do i disable Turbo boost?

Yes, they're not demanding so there is no need to run it at 300+ fps with fans at max. You need an app to disable turbo boost - https://github.com/rugarciap/Turbo-Boost-Switcher

We already know that Apple likes the keep the fans from spinning up until temps get pretty high so if they're running at 6000rpm I wouldn't manually set them lower. Sure the CPU will throttle itself if it gets too hot but that kind of sustained heat can hurt the longevity of components in the machine.

Apple is more aggressive with the fan speeds on newer MacBook pros. It's better than how they used to be...running up to 100C before ramping up the fans...

I'd just use it as is. It' an ultraportable notebook that has tons of power crammed into it. It's going to run hot and the fans are going to ramp up.

Just be sure you use it in a cool environment and on a hard, flat surface when gaming or doing anything else that taxes the machine a lot.

I'd prefer to run it as it is.. But coolers running at 6000 RPM playing a 10 year old game is not workable.
It is too loud, so it seems the best option would be to set it for 4000 rpm while gaming and keeping the CPU / GPU at at 70 degrees.

I believe MacsFanControl controls the fans even if you have it on “Auto”. I’d uninstall it, reset the SMC, and install iStat menus to check fan speeds since it doesn’t mess with them.

I highly highly suggest not controlling the fan speeds manually. That's a really bad idea and can lead to your computer overheating while gaming...You bought a really thin light and powerful machine. Gaming creates heat, it must evacuate this heat. It will run the fans and throttle as needed to keep reasonable temperatures. You can't reasonably play a game on a laptop and not expect to listen to fans. Put some music on or something...

I'll add that you should set a max FPS in game if possible so your computer can 'rest' a little.
For example, when I play Rocket League with my 2018 15" I have it capped at 60FPS, running at 1680x1050 everything on full except AA, and the fans stay on one of their lower settings (not sure what it is, all I know is that it's not very loud!) while the laptop hovers around 72 degrees.

The CPU and GPU won’t throttle down to stay within envelope?

is there a simple way to check temperate? seems like my new 13" is running warm! not sure if it is indexing or what... but a bit odd IMO.... any ideas here?

Sure, you can download Intel Power Gadget - that will tell you the temperature, frequency, and usage of your CPU cores. You can also check Activity Monitor to see what would be using your CPU up and making your MBP warm.

With that said, it's completely normal for a new machine to be indexing for a few days and it will run warm during that time.

Yeah I'm having the same issue with my 13", it starts to reach 50c and more... Keyboard becomes literally unusable to type because it's simply way too hot.

I configured a manual fan profile for this

How long have you had it ?

Ohhhh, and you just bought it ?
No I have had it since 2017 but only recently I did the fan curve thing using Mac Fan Control.

Now the fans sit at 50% on both sides when I'm at the desk. with the laptop on the dock connected to the dual 4k displays.

That allows me to keep the laptop at around 46ºc..... Temporary Fix until I get a Magic Keyboard later this month.
