Silicone oil, most easily available as DOT-5 silicone brake fluid, is an excellent life prolonging lube for sleeve bearing fans. But it must be applied before the fan gets noisy. The brake fluid has next to zero volatile components so it will never dry out and its heat tolerance is far higher than whatever lube is used on the fans so it's ideal for use on fans mounted to hot CPU coolers. One pint of the stuff is a multi-lifetime supply. Silicone oil is also used as a dilutant for RTV silicone to thin it and as fuser oil in some laser printers and copiers. Don't often see ones with a tank of the oil anymore. Most get by with whatever amount is soaked into a high temp felt pad. One place I worked, I'd just sneak a drop from the copier's oil tank whenever I needed to lube a fan in a PC. ;) --- This email is free from viruses and malware because avast!
