I've become extremely dissatisfied with Apple's direction and felt frustrated being locked into the MacOS ecosystem because until recently there was no alternative that I was happy with. What false claims am I making? You do the math. The total I spent on my 16gb x 2 corsair vengeance LPX 3200 DDR4 RAM was no more than 650 AED. On Apple's offical website, the base model 16 inch starts at 9999 AED and selecting 32gb of RAM comes to AED 11,679.00.ġ680 to go from 16 to 32 GB of RAM. Already had a GPU, SSD, monitor, peripherals from my previous dying computer. Motherboard, CPU, aftermarket cooler, case, RAM, power supply, 256gb m2 ssd all came to about 2500 AED from a computer store in Dubai after some negotiating. Once I started streaming video and opening apps, the fans then started, as expected.

I posted a picture in the MacRumors thread with 4 externals (4K, 2x1440, 1x1080) plugged into my base model 16" and it idled in the 50 degree range with no audible fan noise. It's the workload, not the monitors you have plugged in. Plugging an external monitor into your MacBook will enable the dGPU and that will create more power draw, this is nothing new: You can see in their screenshots or menu bar they have Dropbox, 3rd party wireless keyboard/mouse programs, they might have 10 things running in just their menubars! They need to look in the Activity Monitor's Power section to see what the real culprit is.

Even the Mac OS Activity Monitor is a hog in Catalina for some reason and can take 15-20% of a CPU all by itself.Īnd that doesn't even take into consideration all the other apps people have running. What they don't realize, is that using 1 core running at turbo speeds is only going to show up as 15% of the CPU, but draw enough power and create enough heat to trigger the fans!Īnother thing that some of these posters are not aware of, is that running these temperature/fan speed monitoring applications can use quite a bit of power! They're drawing all these fancy graphs, the applications are usually poorly optimized. One of the confusing issues is that people say, "I'm only using 15% of my CPU, the fans should not be coming on." Of course this will make the heat sink more heavy and expensive, but given the robustness of old Thinkpads that did not go easy on the copper, it could work. I suppose one strategy could be to perhaps up the fan speed yet again, maybe at the cost of a little bit more noise, and use heat sinks with fins as finely pitched as the MacBook Air. Where I think the MacBook Pro could do better is if they adopted more of a vapor chamber strategy for the heatsink, but as you mentioned the radiators are probably going to be the limiting factor, seeing as there's really not a huge temperature delta going on here.

Measurements by Notebookcheck seem to suggest that the MacBook Pro is already doing fairly well compared to PC OEM solutions, especially given the size of the enclosure and the fact that unlike Asus in the Zephyrus, they're not using 12V server level 60dBa fans in a laptop. Modern Intel notebook processors like these are likely running close to 80W and 65 steady state - They've got up to 8 cores to do this. People are trying to put CPU+GPU+RAM packages that are anywhere from 25W to 45W TDP in laptops that are physically too small for them. At least the 12 inch Macbook from a few years ago which was truly fanless uses an appropriately low powered CPU.ĭisclaimer: used to do systems engineering for a server manufacturer a long time ago, after you've gone through a dozen iterations of ways to mount skived copper heatsinks on dual socket motherboards in 1U cases, with various fan solutions, you realize that everything that is not acoustically terrible is some sort of compromise. Whenever I see a laptop with a >15W TDP CPU in a super slim package with a tiny heatsink/fan unit, no matter if it's from Apple or another vendor, I'm very suspicious.

Or the management/product design group has overridden the input of the people who actually know how to design thermal solutions, because the laptop CANNOT be 2mm thicker. If I had to guess they know what they're doing engineering wise, but they're taking a calculated (and poorly thought out, in my opinion) risk that a small percent of people will regularly peg the cpu at 100% usage, and they're further relying upon clock rate throttling and the cpu die thermal sensor to keep things from melting down.
