How to Cool Down Your Laptop


why my laptop is hot

If you've ever used  a laptop in your life,  chances are you know what it's like  when it gets way too hot for comfort.  It's uncomfortable.  Unsurprisingly, when you try to pack  that many electronic components  in such a small space,  heat is a real issue.  


And there's actually an entire industry  based around trying to keep laptops cool.  But other than getting burns on your skin  from an overheated computer,  how do you know your  laptop is actually too hot?

One easy thing to keep an eye on  is your CPU temperatures, obviously.  It's quite normal to see your  CPU heat up under heavy use.  

But if you laptop feels painfully hot  or if it's behaving strangely,  my laptop wouldn't do that,  download a reputable  hardware monitoring utility  and check your processor's  core temperatures.  Both AMD and Intel specified temperatures  of around 100 degrees  Celsius as a maximum,  but a good rule of thumb  is that if you're getting  over 90 degrees under load,  you should probably try  to cool your laptop down.  

And for you gamers out there,  this is a good guideline for  your discreet GPU as well,  and your attitude.  Maybe a short break is in order  before you start friendly  firing on your support units.  You know.  

But processor temperatures  aren't the only thing  to watch out for.  Batteries don't particularly  like excessive heat either.  I mean, does anyone?  

And their tolerances are  lower than they are for CPUs.  The lithium-ion batteries  common in modern electronics  should be kept below 45 degrees Celsius.  Although they can operate  at higher temperatures,  up to around 60 degrees or so,  some laptops will stop charging  once the batter temperature  hits 45 degrees.  If your battery is often running  at high temperatures under load,  its life might be shortened,  and it might even swell up on you,  like physically get larger,  which can damage other laptop components.  

I once had a laptop track pad  start to bulge out of its housing  because the batter underneath was swollen.  Not good.  And on the subject of high  temperatures causing deformation,  heat can actually cause the  soldering inside the machine  to crack or warp.  


Infamously, this phenomenon  was at the center of a controversy  that happened a little over 10 years ago,  called Bumpgate,  sounds pretty fun,  that involved Nvidia and Apple.  

See, Nvidia sold a bunch of GPUs to Apple  that turned out to be defective,  but the issue wasn't  the GPU dies themselves.  

Instead, the soldering that  held the die on to its package,  arranged into small balls called bumps  was apparently made of  a different material  that didn't behave in  a way Nvidia expected  once they heated up.  

As a result, many of these  bumps expanded excessively,  leading them to break entirely.  Some reports indicated that failure rates  were as high as 40%.  

To this day, relations between Apple and Nvidia  are rumored to be quite frosty.  No pun intended.  And Apple started many of its Macs to AMD graphics in the wake of Bumpgate,  though it's never been confirmed  exactly how big of a role that  particular incident played.  But back to heat inside your laptop.  


We know that it's bad.  But if your monitoring software indicates your temperatures are too high, how do you cool things off?  Well, you start off with the simple things, a good old big glass of ice water.  

Just kidding.  Don't do that, that was a joke.  You can check the ambient temperature  of the room you're in,  try operating your laptop  on a hard, level surface  to ensure that the air vents  will have clearance to breathe,  and blow out those vents  with some compressed air  to make sure they aren't  clogged with dust.  

If this doesn't work, it’s not a bad idea to check if any curves you've set aren’t somehow messed up.  


And if you're still scratching your head, pop off the panel, and ensure all the fans are running properly  and aren't unplugged or straight up dead.  

Now if you haven't fixed the problem at this point, you got to start asking questions about your competency as a laptop repair person.  Just kidding.  A good cooling pad to sit your laptop on might be a good idea.  

You don't necessarily need anything super expensive.  Just find something well-reviewed.  


And remember, if you're in  the market for a new laptop,  you can save yourself a headache  by reading or watching reviews,  and making sure the  model you're looking at  hasn't been too hot to  handle for other customers.  

Although there are a lot of great laptops out there, some of them just aren’t designed all that well when it comes to heat dissipation.  So do your due diligence, so you don't end up with a laptop bezel you could fry an egg on,  even if you're feeling a little puckish  for a breakfast sandwich.  

They say breakfast is the most important meal of the day.  It helps your brain.  And you know what else is good for your brain?  Brilliant!  If you're a student, a professional,  or just someone who wants to  understand the world better,  check out Brilliant,  the website that helps you  reach your learning goals  by helping you work on them  just a little bit every day.  

Brilliant offers interactive explorations and a mobile app to help you master concepts in math, science, and computer science.  The courses take complex concepts and break them up into bite-sized chunks.  Over time, you'll be amazed at what you can accomplish.  

We suggest checking out their mathematical fundamentals course,  which has been redesigned  with interactive features  to help you with the foundational concept  behind algebra, number theory, and logic,  which make it a great  resource for STEM students.
