How often do you need to dust an asic? After a month? More or less?
If you see dust on the outside, there is more on the inside. Dust can create a path of less resistance and cause voltage issues. You want to blow out your devices when you see dust really start to build up on the fan blades. You should not blow them out when it is connected and running. You must use very dry dry air. those compressed air in a can work as long as you never blow the contents raw and in liquid form. So never shake the can while using, never turn it sideways and especially upside down while using.
Thanks soo much for the info!
