Thanks, was just about to ask

God I hate those no-contact temperature sensors - people use them on literally every surface without realizing there's something called thermal emissivity - different surfaces reflect and radiate heat differently. A glass or metal surface will reflect heat much differently from wood or drywall surfaces.

These cheap no-contact temp sensors usually are set to measure the heat from surfaces found in home construction - drywall, wood, painted surfaces, etc. Some of the nicer ones can have adjustable emissivity but most people never tinker with that setting.

Now if you're using a nice FLiR thermal camera, you absolutely need to tinker with emissivity to get a good image.

Given the fact that the display on this temp sensor does not display the emissivity setting, I'd assume it's fixed - and not set to accurately read the temperature of that metal surface.

Speaking from experience with mine set to .95ε an anodized aluminum surface actually comes close to what wood measures at same temp.

Fun fact.. the center of the sun is colder, than the surface.

Gaming on mac huh!??!

I live in a tropical country. It has me concerned about how well the m2 air would perform without a fan. Hopefully the next 13” pro does not have the touch at and I’ll just get that to be safe.

I push my M1 pretty hard living in Florida and I have no issues even outside.

it boots its clock till it hits its thermal limit

Dell XPS does the same thing. its fairly normal for a lot of higher end laptops.

if it runs at 90 degrees then youre technically leaving performance on the table...
