Thermal paste

What to do on a Sunday afternoon and your computer gets a little on the hot side?....and you just find out that the thermal past between cpu and dissipator is worn out..?

First you test with aluminum foil:

...and fails miserably...

..then you remember something about chemistry and "Fluor" supposedly is a nice conductor but toothpaste has a tendency to dry problem: just add some silicon based gel or a petroleum derivative like the following product to remove cloth stains...

Mix on a 50/50 proportion, or 70/30 or...whatever......put on the CPU (careful for not to spill on the sides) then assemble everything again:

first the dissipator

then the fan

Now test it!:

 ..before the toothpast and supergel mix it was 2600RPM and around 70ºC

I'v been running over a week on this mix but eventualy one of this days will place a proper thermal past.... next experiment is to find a catalytic converter for the car to run on water! :)

Have a nice week!
