- therein 5mo agoHonestly m1 was very cool no matter what workload you threw at it but at this point m4 max does get pretty hot even with just web browsing.
- gpm 5mo agoI've definitely had my m1 air get uncomfortably hot to touch - particularly right above the keyboard. (While doing developery things)
- inventor7777 5mo agoCan't say I've ever thought of a word like "developery", but now that I've seen it I like it a lot :-)

- lifestyleguru 5mo agoTBH there was a shameful period when producers were "reinventing" QWERTY keyboard and had a better idea whether Ctrl key should be present and where it should be located. Remember when Apple removed the Esc key?
- dajonker 5mo agoI recently installed an app to manually activate the fans on my MacBook Pro M1 Pro as I've never been able to trigger them over the past 4+ years. Just to check whether the fans even work (they do).
- amluto 5mo agoYou must be using only lame languages like C or Go or Python that aren’t optimized for laptop warming during compilation. Try using a Real Language with a Real Compiler, like C++ or Rust or Swift, and build decent-sized projects using all cores. (All joking aside, this is why I have a MacBook Pro. Compilation easily hits the Air’s thermal limits and the performance boost on the Pro with its fan is impressive.)
- woozlewuzzle 5mo agoYou could also build Chromium from source. It makes my M1 Max's fans sing.

- asdff 5mo agoI get them going full blast in 2 minutes from cities skylines.
- tom_ 5mo agoI left my Mac Studio running at 100% CPU on all cores for 14 hours, and the case ended up noticeably warm to the touch. It is possible!
- asdff 5mo agoTry increasing to 10 cores. Works on my m3 pro.
- ale 5mo agoHonestly i prefer my macbook frosty
- selimthegrim 5mo agoSir, this is a Wendy's
- jvuygbbkuurx 5mo agoI just need to build our monorepo
- Onavo 5mo agoI think any next.js project will do the trick
- amomchilov 5mo agoHow big is the risk of condensation when you bring a cold laptop inside? All their spec sheets say they support up to x% _non-condensing_ humidity, which I’m guessing is about the dew point?
- ericpauley 5mo agoThe uncomfortable fact about the mentioned Wisconsin winters is that inside dew point tends to be quite low.
- vibcdingenjoyer 5mo agoI’ve always been told to let electronics and musical instruments slowly warm up in their case after bringing them inside. Supposedly reduces the chances of condensation forming.
- 1e1a 5mo agoAnother (more useful) option is to render an animation in Blender, or run a local LLM.
- Scubabear68 5mo agoNeeds 2019 in title, this is Intel MacBooks not Apple Silicon.
- ciupicri 5mo ago[flagged]
- rogerrogerr 5mo agoThe target market of the "Neo crap" doesn't care and/or isn't pushing workloads that come anywhere near saturating it. It's a laptop that doesn't bend, has a decent screen, has a decent battery, and isn't full of adware.
- ciupicri 5mo agoThe article was about warming up a laptop. Neo can do it too.
- rogerrogerr 5mo agoAnd your comment was calling it crap for some reason. We wouldn’t be having this conversation if you’d left that apparently superfluous word out of your comment.
- inventor7777 5mo agoHow does the Neo getting to 100°C make it crap? By that logic, aren't all older Intel/x86 chips crap? If anything, I find it impressive that a small laptop CPU can do 100°C without a problem...my i7-7700T M710qs hit 75°C and throttle within a minute if I use a tool like y-cruncher or stress-ng. To be fair, totally different purpose.
- wtallis 5mo agoFor a very long time now, it has been the case that in the short term most processors will boost high enough for the die to reach around 100°C. When you see a reading substantially lower than that like your example of 75°C, either the system has throttled for a reason other than processor die temperature (eg. throttling to limit the temperature of the outer case of the machine) or the temperature reading you're seeing does not correspond to the hottest part of the chip and the throttling is based on the presumption that a different part of the chip that is not directly monitored will be much hotter. In the specific case of the i7-7700T, the "T" suffix for Intel CPUs usually means you have mainstream desktop silicon with arbitrarily reduced long-term turbo limits, intended to be used in small form factor PCs with limited cooling capacity. Its limitation to 35W sustained and official Tj max of 80°C are artificial and essentially fiction, and the same silicon will readily do 91W sustained with a Tj max of 100°C as seen on the i7-7700K. Processor temperature under load tells you almost nothing about the power draw or efficiency of the chip, because the temperature can be controlled to almost any value desired through a combination of varying cooling effort and varying clock speeds.

- sunrunner 5mo agoJust do the trick in reverse, surely? yes no > /dev/null
- crote 5mo agoUnironically, yes. My M3 Macbook Pro's palm rests get uncomfortably warm during regular IDE use. It doesn't get hot enough to spin up a fan, but it is enough to be distracting.
- HDBaseT 5mo agoFor years at work I've been just using Cinebench as a hand warmer on various Macbooks.

- jerlam 5mo agoI think my last Macbook was Wisconsin-locale instead of California. Closing the lid and putting it to sleep actually caused it to heat up (until the battery died).
- simulator5g 5mo agoIt had the soul of a PC
- kristianp 5mo agoOr you could get a laptop that doesn't have an metal shell, like a thinkpad.
- Caracas288 5mo agothey often have a magnesium bottom shell
- simulator5g 5mo agoOr just leave the machine plugged in and turned on for like 5 minutes while you grab a coffee or have a conversation. It doesn't really take that long to warm up to room temperature. Unless this guy is like biking 15 miles to work in the winter in which case, he is doing Wisconsin wrong, you're supposed to drive to work with a beer to warm you up.
- Hobadee 5mo agoI'm from California... What is this "cold" you speak of?
- int0x29 5mo agoThe Donner Party begs to differ
- isomorphic 5mo agoFloridian. I thought "frozen lake" was some sort of Intel CPU reference.
- nottorp 5mo agoYou don't know how right you are. I don't think Apple ever tests their hardware outside the CA climate.
- xgkickt 5mo ago“Designed in California, for Californians” was too long.
- splittydev 5mo agoAlternatively, you could try compiling an Xcode project. That should do the trick as well.
- ralphc 5mo agoI still use a 2019 MacBook Pro, in 2026 I found the best way to warm it up was to use it daily and not blow the dust out of it for 7 years. After I opened it up and did that it's running a lot cooler.

- smarks 5mo agoWarming up a 2019-era (Intel) MacBook Pro was never my problem. Quite the opposite. Those machines ran notoriously hot. The later macOS releases, combined with company-mandated crapware, made it worse. Doing an ordinary build or starting a videoconferencing session was enough to cause the fans to run. On a warm day the fans couldn’t shed enough heat and so the system would go into thermal throttling. The OS would occupy a core with a 100% kernel_task that didn’t do any work but which would serve to prevent actual work from being scheduled onto that core. When four or five out of the six cores were occupied by kernel_task, I knew I was in for a bag of hurt (to steal a phrase from Steve Jobs). Responsiveness went completely to hell. The machine became effectively unusable. After a while my normal procedure was to run with the thing sitting on top of an ice pack. That would let me run a 60-90 minute video conference without troubles. The only redeeming feature of these machines is that they could emulate old x86 hardware at speed. That allowed me to run old apps on old OSes without having to keep old hardware running.
- recursivecaveat 5mo agoMy Intel MBP would noticeably raise the whole room's temperature, while the fans ran so loud. We had some corporate security software that would occasionally go haywire and lock up 100% of a core until you rebooted. If you got that at the same time as a video call it would become too physically painful to touch any part of the metal body with bare skin.
- alexwwang 5mo agoMaybe the same type. Each time I call the LLM api the fan starts to work and make big noise. The temperature in the room is going up noticeably for 1-2 degrees.
- embedding-shape 5mo ago> Each time I call the LLM api the fan starts to work and make big noise So every time you do HTTP calls? Nothing there should spin up your fans, unless you use an agent with an horribly broken TUI, I've heard there is a few of those out there. But remotely calling LLM APIs really shouldn't be taxing on your local device, something somewhere is wrong/bad if that's what you're seeing.
- villgax 5mo agoThis is now running Cyberpunk or an LLM locally
- diimdeep 5mo agoOr something useful, save space, compressing some talk or edu video, just 6 fps is usually enough for slides or code, opus audio can go as low as 32k and still be decent compared to source quality, expect 10-15x size reduction ffmpeg -hide_banner -y -i in.mp4 \ -vf "fps=6,format=yuv420p,scale=960:-2:flags=lanczos" \ -c:v libx265 -tag:v hvc1 -crf 32 -pix_fmt yuv420p -preset fast \ -c:a libopus -b:a 82K -application 2048 \ -c:s mov_text \ out.mp4 can go more crazy with this soup -x265-params "keyint=800:min-keyint=24:scenecut=20:ref=8:bframes=16:b-adapt=2:rc-lookahead=80:rd=4:subme=5:deblock=1,1:aq-mode=3:aq-strength=0.4:psy-rd=0.4:psy-rdoq=1.0:qcomp=0.7:qg-size=64:rect=1:amp=1:strong-intra-smoothing=1:limit-modes=1:limit-tu=4:rdpenalty=2:tu-intra-depth=4:tu-inter-depth=4:me=star:no-allow-non-conformance=1" \

- fastjack42 5mo agoNow do the opposite for the summer! Show me a command line that cools down the machine! ;)
- p0w3n3d 5mo agoDoes this work with M series ? M series is much colder and my fingers hurt <sob>
- dasKrokodil 5mo agoSpeaking of cold weather and warming up computers... I've had my fair share of long bicycle commutes during cold winters and I always wondered whether booting up the laptop right after arriving has any effect on the long-term reliability? Like, are there any components which suffer from being activated when they're really cold?
- nottorp 5mo agoI always leave the laptop untouched for at least 10 minutes when coming in from the cold. Don't know if it helps but it makes me feel better.
- lebuin 5mo agoI try to leave my laptop untouched for as much as I possibly can. Definitely makes me feel better too.
- ivanjermakov 5mo agoAt the first half of your comment I thought you would suggest using laptop as a back heater during cold weather rides!
- Tade0 5mo agoThe battery might need warmup, but it would have to be significantly below freezing outside to affect it. Electrolytic capacitors can freeze up but again, you'd need a Yakutia-like environment for it to actually pose a concern. Lastly I've heard of circuit boards warping from going from really cold to really hot, but those were power components.
- Filligree 5mo agoIt increases the chance of solder cracks, which is one major cause of failure. Thermal cycles in general will do that, however, and home computers are designed to survive a lot of them. So overall it’s not something I’d worry about.
- Cthulhu_ 5mo agoModern Macbooks have this issue, the other day I realised I had never heard the fans of it run, so I was wondering if they actually worked. Found a web based benchmark tool that will run your CPU and GPU at 100% each. While temperatures went up to 90 degrees science... still no fans. Ended up installing a different utility to manually set the fan speed to confirm they worked. I don't know what they did but it's good.

- traceroute66 5mo agoTo be fair, the fundamental problem here is the author's resting of wrists to type. This applies to any computer, Apple, Windows or Linux. Desktop or laptop. If your typing on any computer is dependent on you resting your wrists whilst typing then it is indicative of poor typing technique and/or posture. And ironically the very thing you think you're trying to prevent by resting your wrists (carpel tunnel and/or strain) is likely to be aggravated by over-reliance on wrist wrests due to the added pressure on the wrist.
- mexicocitinluez 5mo agoSlightly quicker way to do this is opening Microsoft Teams.
