But corrosion on computer heatsinks is quite common. I suspect it's because of contamination being blown on to the heatsink by the fan, and maybe combined with the heat. Dust will have all sorts of random crud that's going to then get cooked on the heatsink.
I've noticed the issue MUCH more in computers used near the sea. The salt in the air end up in that dust and that certianly encourages corrosion.
But if a machine has lived in a filtered and air conned server room, and always breathed clean air, the grills and heatsinks can be spotless after ~10 years, inspite of running warm the whole time.
Hi well of course it comes from heat and water that is what happens over time with any iron ore it reverts to it's original state a ferrous oxide.
so why as the question in the cars section why not in computers where you would get a much better response.
No. That's moisture/humidity & oxygen....
To have rust, you do need moisture. Oxidation ...
I have a laptop which has never been exposed to water or liquids.
But somehow I have rust where my processor's fan blows out the extremley hot air prior to over heating.
Does any know why there would be rust. Does it have to be from a moisture.
Can it be from over heating of materials causing element break down.
