It becomes hot really fast when I put it on my knee or stomach. How do you guys cool it? Do you use any cooling pad for MBP?

I keep it on a table and not on the bed, close to myself. Also, I run a bit of cooling jelly everywhere, where necessary
 
That depends on what your doing. If you do happen to be doing something that'll start up the Discrete GPU there's pretty much nothing you can do to stop it from heating up. A cooling pad would really only separate the heat from your lap they don't really work that effectively on MBPs.
 
I do nothing, but I manually manage the fans and graphics cards with gfxcardstatus and SMC Fan Control. Certainly helps when I want certain configurations and fan speeds. But generally, it's fine on it's own, no cooling pad needed like most cheap PC laptops.
 
I use compressed air to blow out the dust that builds up in the heat sink grill every year. That's it. Gives impressive results too, last time I did it dropped my idle temps by ~10 C.
 
I dip mine in water when it heats up too much. No problems so far.







not really.
 
Notebook computers are designed to sit on a desk. That's why they have rubber feet on the bottom. To create room for air to circulate beneath it.

You are not supposed to place it on a bed, your stomach or knee, since that creates a hot spot. It's especially hard on Macs since they don't have large cooling vents on the sides or back. They dissipate the heat throughout the keyboard, aluminum case & small slot beneath the hinge.

Therefore when I want to rest mine on my knee or lap, or some other uneven surface I use a slim, light, X-Pad. It's got a nice grippy bottom so it doesn't slide and it allows air flow below the computer.

Just use it, if it's still running it's not over heating. That said, I've under volted mine using CoolBook (only for C2D, there isn't a version for iX processors, yet) which lowered my temps under load a ton, but I did it for battery life (which was also greatly increased).
 
I keep mine on a laptop cooler just to allow air circulation under the laptop, the fans are off. I raise the built in fans to 2900rpm minimum, which is just below the noise floor of the room.
 
I do the following things to keep my MacBook cool:






...get the idea? Built in is everything you ever need to keep it operating normally and safely. Seriously though, we all know that getting dust in your laptop makes it run hot, so I guess you should tape up all the openings and vents.

Okay, I am LMAO at some of the responses. Wonder if the OP was even seriously asking or if he was trolling?

Anyway, I was worried about heat because of reading on here how hot the MBP gets. I use mine on my lap with no lap desk all the time for hours and it gets pretty warm but never so hot that I can't stand for it to be touching my bare legs. I have a lap desk that I use in the bed so it doesn't get in the blankets.
 
i use mine on my stomach a lot when I'm in bed. i just make sure nothing is blocking the fan. temp is at 119 right now with fan at 2000 rpms

@.@ You confused me for a second...
48.3°C = 119°F

Normal idle temperatures are 30-60°C and at 2000RPM. If it's any higher, take it to an Apple Store.

@OP, If you're complaining about normal idle temperature getting too hot, get a freakin' desktop or DEAL WITH IT. There is nothing you can do other than damage portability with a bulky cooling pad, which would make the concept of a portable computer pointless.
