If you have a little bit of CooLaboratory liquid metal TIM left over, do NOT, I repeat DO NOT, use it on an aluminum CPU cooler. The results can be drastic as “SirGallium” learned below. The horror….the horror…but really cool to see, as long as it was not your HSF.



From CooLaboratory’s PDF:

“Coollaboratory Liquid Pro” was designed for use with high quality coolers made of copper or silver. Aluminum coolers are unsuitable (of course this applies only to the cooler’s contact surface onto which “Coollaboratory Liquid Pro”. is spread). Note: Do not use cheap aluminum coolers. Their quality is not very high, and aluminum is not resistant against our Liquid Metal. Aluminum could form an alloy with “Coollaboratory Liquid Pro” which would react with the surrounding air’s humidity. A black stain forms after a while, showing insulating qualities. Therefore: No contact of “Coollaboratory Liquid Pro” with aluminum. NO ALUMINUM COOLERS!
