Watercooling

[Roman2K~]

Joke... kind of. Actual cooling via water but no watercooling in the traditional sense. Very interesting video by Linus:

"Water Cooling the Macbook 2015 - Increased performance or dead Macbook!?"

Fun! My 1.2 holds 1.9GHz - 2GHz with all Core`s lit up holding at around 8W, then it drops off to 1.3GHz & surging back to 2GHz.

Now place it on a small powered cooler, turn it on and the 1.2 MacBook will hold 2GHz as long a you want...

Well, I think It's time for a USB-C dock with fan-cooler where the rMB sits on while docked. This way it's a quite OK powerful machine when sitting at the desk.

Q-6

What do you do to make it throttle? Do you push it or it just does it naturally?

Placing my 1.1GHz on an ice pack makes it stay at 2GHz at full load instead of throttling down to 1.9GHz-1.8GHz. No noise either! But it will only last a few hours. Not very practical, but a funny experiment!

This is what I use, as the side supports open individually you can place the fan directly under the MacBook`s CPU

No I forced the CPU to max all cores, using ''Yes"

From Terminal
To start;
yes > /dev/null & yes > /dev/null & yes > /dev/null & yes > /dev/null &

To stop;
$ killall yes

Alternatively install Handbrake and trancode a large MKV to MP4, that will light up the CPU just as well. To observe the CPU behaviour install Intel Power Gadget 3
