why is my macbook really hot?

Pretty sure everyone in here might be overthinking this. Macbooks generally get hot when they are on a wifi connection because the transmitter emits more heat within a computer. If you try a ethernet connection it generally keeps your computer cooler. Pretty much every laptop on the market will heat up on a wifi connection until they design a better heat dissipation process.

try this SW, good for retina fan control(automatically).

@snowboarder4x4

i have someting to ask you regarding with my MBP i already installed smcfan controler on my my mac but when the temperature reach about 75 dgrees why is it that the RPM still the same it won't change to what i have set in the settings? i set 2000rpm by default and the high rpm i set to 6000.

Smcfancontrol wont adjust fan speed according to tempature. Only sw can do it is fancontrol, please check the link I posted above and delete the smcfancontrol before installing.

@sig, why remove my post about the obvious fact this is a LAPTOP with the emphasis on LAP????

I never paid several thousand dollars for a laptop that cooks my leg after five minutes. It's going back unless therre's an immediate fix passed on to me.

KevG14, greetings: You will be hard pressed to find in any Apple publications where a MBP is categorized as a 'Laptop'. The term 'Notebook' is used for good reason, to separate it from laptops.

If the heat poses a problem for you, then perhaps you should return the MBP notebook.

Ciao.

I'm a Dr of mediicine and it worries me about the extreme level of heat this item emits. It actually burns on touch. Notebook, laptop, = symantics, the fact is you would use this on your lap and or pick it up after use and risk burns. Mine is going back with a stinking write-up. Thanks for the patronising answer by the way.

i dont think tht its actually working out well for me but yea besides all the rumour ...keeping it on the table wen its hot and on ur lap wen it not ...is the proper way ....or else laptop cooling pad is tht device which will never allow the computer to generate the heat....it ll keep coooling it instantly....!!!!!!!!

even on buyng the laptop cooling pad u ll then difinitely hav to keep it on ur desk or table ......

I had the same problem with my 2008 13 inch MacBook Pro. I use all kind of things to keep it clean and tidy but it runs hot as heck, and the smcFanControl noted below really helped. Thanks!

I need to upgrade memory and all that--I already upgraded the OS, and honestly I don't ever remember a Windows laptop lasting this long--it's a good machine.

Thanx Snowboarder 4x4! I downloaded Fan Control and Love It! You ar Awesome!!!

I was having the same problem but can't find the thread now that fixed my problem. Someone told me to go to spotlight and find the activity monitor. Zumocast was running in the background and had my CPU up to 99%. I uninstalled Zumocast and everything's fine now.

Thanks everyone you solved my HotMacBook problem! I went into the Activity Monitor and found that the back up software I used called Carbonite was running at 90-100%..shut that off and the MacBook is nice and cool! I also downloaded SMC FanControl but really don't use it or need it now! Now if I could only get a BigMac from McDonalds drive through that was Hot!!

Happen to me just try to turn brgihtness down

I get it too, sometimes. Everyone is right though. Don't use it on your legs. I believe that's why Apple doesn't use the term "laptop" and uses "notebook" instead. Trying to get people to stop even thinking that way.
