Which eGPU with a 4 monitor setup to reduce fan

hello all,

i'm having a macbook pro 16, 2.3ghz, 32gb, 5500M 8 GB.
i'm running 4 external screens on it (2x 34", 2x 27"), three of them connected
directly (HDMI->USB C) while one is connected on a plugable Hub which i also use as
power supply.

I'm using TURBO BOOST SWITCHER PRO to deactivate turbo boost.

I'm having several Tabs in my browsers for Crypto Trading Websites, these make my Fan going crazy and the laptop (in a vertical stand) is very hot all day and super noisy, and basically heats up the whole room lol.

Does a eGPU Solves this problem ? If yes, which one you can recommend ? I assume i have to pick one
where i can connect all 4 Monitors ?

@jan7007, Reduce fan? Yes, if you pick one that is quiet. It can take the load off the laptop, so it runs cooler. And, if it has a good cooling system, it will stay cool as well. As for heating up the room, you'll probably make that situation a bit worse (as many eGPUs often run more powerful, and power-hungry, GPUs).

I have probably the most quiet of the eGPUs, the Blackmagic eGPU. Either that or the Pro can both run essentially silent (even under heavy load). I've also heard this one is relatively quiet compared to other eGPUs (besides the Blackmagic, which is kind of in a class of its own in terms of quiet). https://www.sonnettech.com/product/egfx-breakaway-box/overview.html

As for recommendations besides that, hopefully someone else here will have ideas. I don't know much about a 4-monitor setup and which would be best for that. I think it should all work well under MacOS if you stick to the right AMD GPUs. If you plan to run Windows under Bootcamp, that's a whole other can of worms (but you've come to the right place).

i was just seeing that the blackmagic egpu is available again. i think i tried to order it a few months ago for testing but it was said they stopped producing !? anyway -  i have seen that it only has 1 HDMI Port ?

 

I'm not so much into tech - but do i understand it correct that i need - for my 4 monitors - an external case (like razer core x chroma) and put there an graphic card with 4 Montor ports inside ?

@jan7007, You can connect three displays to the Blackmagic eGPU. One to the HDMI port and two to a Thunderbolt port (with adapters or Thunderbolt dock - The least expensive would be a Thunderbolt 3 to Dual HDMI adapter).

For four displays, yes, you need the external case (eGPU box) and install a GPU with 4 ports inside. The Buyer's Guide has a list of eGPUs and the Builds database has a list of example builds that others have made.

Mac mini (2018), Mac Pro (Early 2008), MacBook Pro (Retina, 15-inch, Mid 2015), GA-Z170X-Gaming 7, Sapphire Pulse Radeon RX 580 8GB GDDR5, Sonnet Echo Express III-D, Trebleet Thunderbolt 3 to NVMe M.2 case

@jan7007, The cooling capacity of the 16-in MacBook Pro is unfortunately limited. Having an eGPU to drive all external monitors will definitely idle the dGPU to keep the laptop cool and quiet. Your challenge atm is to find a reasonably priced Radeon graphics card with 4 monitor outputs. I would say the Sonnet Breakaway Puck 560/570 on the used market might be a good choice. Here's a build with a 2018 Mac mini to use all four ports (3x DP and 1x HDMI).

@jan7007, Yes from the description it looks like the card will drive 4 displays in MacOS.

just wanted to give feedback.

 

i just set up the razer X +  sapphire rx580 8gb with 4 monitors.

works amazing, no setup problems, macbookpro16" fan speed and heat absolutely reduced !

 

i dont have to install separate drivers for the graphiccard, right ?
