Dan wants to know why his laptop gets so hot
I use my laptop for as my primary computer. I really like the convenience. I was wondering — why does my laptop get so hot? I look forward to your newsletter each week. Great job! Thanks Dan.
Thank you, Dan. Your laptop has a bunch of stuff inside that is all crammed in there – there’s not much room for air to circulate, so there’s not much chance for cooling breeze inside it. How’s that for a techie explanation? It’s not very technical – but it is true. Laptops run hot – that’s a fact. But it doesn’t necessarily mean your computer has problems.
If your laptop is experiencing unexpected shut-downs, blue screens, or is becoming increasingly slow – you may have a serious problem on your hands. You should have a professional take a look to make sure there are no significant problems with it.
But if it seems to be running normally – shutting down and starting up normally – and you don’t have error messages or spontaneous shutdowns – then your laptop – like most laptops – is just running hot.
What can you do about it? Well …
Don’t use your laptop on your lap top.
Laptops are cooler when used on a flat, hard surface – like a desk or a table. If you’re one of the kind of people who likes to sit in the Lazy Boy recliner — use a TV tray to hold your laptop. It’s flat and it’s hard. Just remember to wipe the food crumbs off of it first. If you use your laptop on your lap – it will run hotter and so will your lap!
Check you computer’s fans:
If you feel warm air blowing out of the fan vents then you know your fans are working. If you barely feel any warm air – or none at all, your fans could be clogged with dust and dirt. If you have a newer laptop, unscrewing the case and clearing the dust and dirt from the fans with compressed air.
Give your laptop a break
If you play games on your computer or watch flash videos – these are resource hungry applications. They can cause your laptop to heat quickly. If you’re a gamer or just enjoy watching videos on your laptop – take a break every hour or so and give your processors a breather. If you run graphics programs or audio or video editing software, you should keep in mind that some of these kinds of programs put a heavy load on your laptop’s resources and can make it run hotter. Remember to give your laptop a rest or a few minutes every hour or so, if you’re using it for resource-hungry applications.
Use SpeedFan to control your laptop’s temperature
There’s a software program that may help you keep your laptop running a bit cooler. It’s call SpeedFan for Windows. It’s not necessary to install a program like this to keep your laptop from overheating – but it can help your laptop to stay a little cooler. Plus, it’s fun to play around with this program and see what’s going on inside that furnace of a laptop!
Here’s a little information for you about SpeedFan from the developer’s Web site:
“SpeedFan is a program that monitors voltages, fan speeds and temperatures in computers with hardware monitor chips. SpeedFan can even access S.M.A.R.T. info and show hard disk temperatures. SpeedFan supports SCSI disks too. SpeedFan can even change the FSB on some hardware (but this should be considered a bonus feature). SpeedFan can access digital temperature sensors and can change fan speeds accordingly, thus reducing noise. SpeedFan can find almost any hardware monitor chip connected to the 2-wire SMBus (System Management Bus (trademark belonging to SMIF, Inc.), a subset of the I2C protocol) and works fine with Windows 9x, ME, NT, 2000, 2003, XP, Vista and Windows 7. It works with Windows 64 bit too…”
Here is a screenshot of SpeedFan in action on my laptop computer.
And while this is off topic, SpeedFan also gives you complete information about your hard drive(s). As you can see, I’ve been abusing mine but it’s still in pretty good shape:
It looks like I have a few problems going on with my hard drive – but not to worry – I have full image backups at the ready just in case.

Getting back to hot laptops: Just remember – laptops run hot. Just because your laptop feels hot to the touch does not mean there’s something wrong with it. If you look on the Web you’ll see hot laptops have engendered a whole line of laptop cooling pads. If you use your laptop on your lap — you might want something cool to set it on besides you.
