Upgrading a laptop's cooling ability

[Leung]

I have this Fujitsu Lifebook that gets pretty hot, 60/85' C, when just surfing the internet or watching Netflix. All the threads i have read about this laptop say that it's pretty normal to get that hot because of the design so i was thinking of some how upgrading its cooling ability.

I found this article about adding heat pipes

http://therandomlab.blogspot.com/201...oling-mod.html

and after the author added two more heat pipes to help channel away heat, his/her laptop dropped about 12 degrees Celsius.



This picture shows how the heat sink is set up in my Fujitsu. It only has one short heat pipe right above where the CPU is. I wanted to add another heat pipe so that it covers the GPU also hopefully dropping the temps of this laptop.

Since i used to tinker around with the insides of Xbox 360s, i have an old heat sink sitting around. I was thinking of salvaging that heat pipe and using it. The only problem is in that above pic, shows a flat heat pipe but the one from the 360 it is still tubular form. Any ideas of how I could kind of flatten it out?

As for attaching it to the Fujitu's heat sink, i was thinking of using Artic Alumina thermal adhesive instead of soldering it on because it is heat conductive and permanent plus it is good up >150C.

I wanted to go this route because it makes it still portable. If i just added a laptop cooler underneath that uses USB to power it, then it is not really portable anymore.

I undeleted this because I thought it was an interesting idea. To flatten the heat pipe, Just use a hammer and softly tap it into shape. They're hollow inside so they'll flatten just fine.

The thing is, adding a heat pipe is one thing but if you can find a fan that flows more cubic feet per minute of air through the radiator, it'd help better.

Yeah i've looked at fans but they all seem to be stock replacements which was how i originally stumbled upon adding heat pipes instead.

I think i'll use a rubber mallet instead because i do tend to be a bit heavy handed. I'm thinking of swapping the heat pipe's position also since the Xbox's is quite a bit longer so i'll have that one touching the radiator fins while the stock pipe, i'll just run parallel like how that author has placed in their picture.


* well crap. while trying to remove the pipe from the fins of the Xbox'x heatsink, i broke the pipe. Guess i'll have to go up to Microcenter to see what kind of cheapy heat sinks they have that i can destroy.

Adding another pipe can help but you also need the radiator to displace it for the fan to remove. First step is selecting a good thermal compound. Arctic Silver USED to be one of the best. I'm not sure which is now.

yeah when i first got this laptop i replaced the dried crusty thermal compound with Arctic Silver 5. I applied some to the CPU and the GPU.

Instead of that why not buy a laptop cooler. They have usb ports where you can plug it in and just go about your business.

I have this one and its very portable and its light . It's easy to fit in your lap so you can type and keep the laptop cool and your leg unburnt especially when you dont have a tray to type on.
