I took my Dell laptop apart last night to fix the USB. I had to remove the heat pipe heat sink and noticed there was only a layer of conductive tape between the heat pipe and CPU. Since the fan has always been running, I figured this needed a little improvement. I just happened to have some Artic Silver 5 heat transfer compound... Wow! What an improvement! The fan used to go to full speed when I was doing serious number crunching. Now it just barely turns on, even when I reboot and double load a driver for my modem (pctspeaker.exe) which hogs the CPU and causes full temp. Why the hell Dell used a POS heat transfer pad is beyond my explaination. Artic Silver 5 rocks. Only a tiny dab is necessary. One tube will do 10 CPUs. |
Been there done that a trillion times. I'm a proud owner of a computer repair business which I'm on a 1 year vacation (6 months left) from building new machines and repair. There are many other types of tweakin methods. good luck... |
| Haven't tried it myself in any critical applications, but have heard that Permatex Anti-Seize Lubricant (the aluminum-based version) does a decent job as a heat sink compound – Only costs about $6 for a good-sized jar (4 ounces?), and it's sold just about everywhere. |
I take it you never have used epoxy, polyurethanes (two part paint or single part glue) or cyanoacrylate glue. I used a makeshift applicator, cut from an old credit card. Took all of 20 seconds to spread a 1/4 BB sized dollop of the stuff. Then threw the spreader away. Computer is MUCH happier and I get much longer time on a charge. |
