You may be able to use a "heatpipe" but that's not as easy as it sounds. Simplest is use air (convection) by blowing cool air into the laptop, but that would depend on how your current airflow is structured. It may be easier to simply fix the fan by opening the laptop. There's gotta be some Youtube video on this. For me the difference between a good cooler and not having one at all is night and day. If I am feeling a lot of heat on the bottom of my laptop, then obviously there is a lot of heat escaping to the outside of the plastic. From my own personal experience, playing high graphics games without some sort of cooling on the bottom is almost impossible. For instance, right now my laptop cooler is broken and as the game progresses, mylaptop bottom gets hotter and hotter and the graphics start lagging and eventually breaking down.
To cool it back down, I hold the bottom up to a large oscilating fan, I also still use the broken cooler as a spacer between the pc and a pillow, so it's not smothered in fabric. I cool the metal cooler down as well, since that is hot, obviously there is a lot of heat transfer going on. The graphic improvement from about 5 seconds of cooling is instantaneous. I do, however, notice on my Dell, that the inlet for the air into the built in fan, seems to be on the bottom, while the outlet is on the left side of the laptop. Horrible place if you ask me, because it's just sucking up the heat the laptop is creating. I'm thinking of new ways to keep my laptop cool. I've considered venting the fan directly into the crevice between my laptop and broken fan, even trying to transfer cold from a drink cooler. Is there anyway to use that exchanger safely on a laptop,
Am I missing something or does physics work differently for me, Several resources can be employed to help keep a notebook cooler. I like monitor the cpu temp and regulate the rpms (increase)on the fan to help keep mine cool. A lot of notebooks do have air intake vents in the bottom. In some designs they are an inlet for air that the cpu fan exhausts out the back vents. Elevating the laptop by means of a cooling pad can help keep the heat sink cleaner by minimizing the dust in air that gets sucked into the intake vents. Dust is a leading cause for laptop overheating. I've take apart a lot of them and the dust is usually clumped up between the heatsink and fan. The heatsink has cooling fins and once they get clogged the cooling ability is drastically reduced. In some designs covers with vents in the bottom of the laptop help cool components such as memory .
Some notebooks are elevated with feet in the bottom base. Others r not. As I mentioned there are benefits to elevating the notebook. Rose -- due to amount of spam your messages don't appear until I approve them. Regarding your questions: just turn the laptop over (with it off, of course), and see if the vents are really dirty. You'll know it when you see it. There should be vents to the sides and maybe under as well, but that's rather rare. Not all freezing and such are heat related. Sometimes you just have to clean it software-wise with CCleaner (free) and uninstall some software that you don't use. Toshiba did not overheat ever. Is this overheating a Dell thing, I just read some of the posts above. I have a Dell that is about 4 mos old. I just lost my Toshiba Limited Edition this past June, it just crashed on me.
