Running notebooks upside down: cooler?

Hi

Is it possible that a notebook turned upside down (on a flat surface) with the lid closed and LCD turned off manually, and attached to an external keyboard will run cooler?

Your thoughts, please!

 

Not a good idea. Most laptops vent some heat through the keyboard, so you will be sealing in heat, not removing it. If your notebook runs cool to begin with, you might be OK, but if you're worried about temps I'm guessing this isn't the case.

Just buy a cheap mount for it, or prop the back up on something. It'll do the same thing.

I run mine "closed" sitting in an HP docking station, but the lid stays propped open about 5cm to allow air flow.

Not recommended, as johnnyflash stated, some heat does escape through the keyboard and keeping it closed will actually hamper the notebook's cooling ability.

 

Besides it is recomended that you don't place excess weight on the display.That way you will be placiing the weight of the whole notebook on the screen.

 

Also don't forget to pour some icewater through the fan vent for some budget conscious water cooling.

 

No, because a closed laptop retains much more heat than an open one. The ideal case would be for the open laptop to be propped up off the desk surface so there is air circulating around the bottom of the notebook.

 

I couldn't afford water cooling in grade 11, so I used cardboard tubing and duct tape to duct outside air from my window directly on the CPU heatsink. Canadian winter kept my Tbird around 15*C under load, and sometimes even a little snow would get sucked in. Looking back I'm really surprised I didn't short something out.

 

I suspect this to be a major cause of global warming. Did you at least put a fine mesh screen between the cardboard tubing and the heatsink?

 

Lol I just wanted to ask the similiar question since I just ordered an external monitor. By a look at al the answers i'm a bit dissapointed though, I thought turning your lappy upside down would be genious.

 

I dont understand why you would even try this on something that's on. Just put something under the laptop to elevate it without covering the fan and maybe try some cooling gel stuff or a fan....Then close the lcd if you want or let the screen timeout.

 

My first thought on reading that line was "What, canadians?"

 

Laptops will run fine with their lids closed, and whether it's upside down or not makes little difference. I used run mine upside down if I was doing something like video conversion since it would let the vent on the bottom get more air (this was before I made a laptop cooler, so unless it was on my lap the bed covers would smother it).

As to whether you'll see any improvement in temperature, it really depends on how your computer is built. One thing to bear in mind is that you shoudn't flip it over too quicky since the drives are essentially like gyroscopes and don't like to change their axis of rotation quickly, you could end up with a scratched DVD or something.

 

JohnnyFlash should have definitely used some mesh to prevent that stray bear from being sucked in :laugh: :laugh: :laugh: :laugh:

 

Thanks, guys, for all your feedback.

Perhaps the idea is, at best, a double-edged sword...

 

And at worst, just a really bad idea.
