Apple’s M1 Ultra Mac Studio keeps its cool with a two-pound heatsink

Apple’s new Mac Studio computer with the new M1 Ultra chip weighs a whopping two pounds more than the Mac Studio with the M1 Max due to differences in the computer’s thermal systems for each chip.

Mitchell Clark for The Verge:

Here’s what the company said in an email to The Verge:

They have the same 370W power supply. The additional weight is due to M1 Ultra having a larger copper thermal module, whereas M1 Max has an aluminum heatsink.

It’s got a heavier metal — at room temperature, copper is 8.96 grams per cubic centimeter, whereas aluminum is a svelte 2.70 grams. That means that, if the design of the heatsinks is exactly the same, the copper version would be over three times heavier than the aluminum one.

We’ll likely have to wait for someone to tear the two versions of the computer down to see if there are any design changes in the Ultra version, but for now, it seems like the M1 Ultra’s added heft can be chalked up to material choices.

  1. The top down square is the same size as Mac mini, 7.7 inches per side. Even rounding of corners looks the same. Hehe… You could use your old Intel Mac mini as a base to raise the Mac Studio and make it more cube-like. Or use that old Mac mini (running “headless”) as optical drive and 2.5-inch data drive connected over Ethernet. And those existing “zero footprint” drive enclosures from OWC and others would also fit underneath, if you need a big inexpensive hard drive to use for Time Machine backup or external storage 😏 (But it might ruin the low-noise experience.)

    More than half of Mac Studio’s internal volume seems to be the cooling system. The computing parts would probably fit into a Mac mini case. That’s incredible, considering it compares favorably to a HUGE Intel Mac Pro with mid-range configuration. Apple has a vast (exclusive) advantage with Apple Silicon. Can’t wait to see new Mac Pro 😵‍💫

        1. I’ve never been one much for labels, but I assure you I support those who stand up for personal freedom, liberty, and personal choice.

          This whole coid agenda has taught me that many of things I was taught as a young pig are meaningless when my sit hits the fan.

  2. I have been a fan of Mac for years. I’ve owned all the previous generations of macbook and mac mini. When I heard about this new model, I was so excited to get it! The iMac Pro is an amazing device with lots of great features and specifications. It has a better processor than any other iMac before it, with more RAM, SSD storage space and even Thunderbolt 3 ports which allows you to connect several devices at once without buying additional adapters like in earlier models (the only drawback: no external display). It’s also extremely slim which makes it very portable but doesn’t sacrifice performance or durability in any way.
