Hey people. I installed the new power supply (corsair builder 500w) after getting fed up with the fan noise on my ex-PSU. I've opened the PSU casing up and luckily the fan uses a 2pin connection commonly found on motherboards. The bigger problem is the amount of the dust embedded in it. Probably over 5 years of it. It needs massive de-dusting. 1) What de-dusting techniques do you use? Compressed air? Where from?! Links appreciated. 2) Am i at risk of left-over electrical shocks in some of the parts? Will probably use this PSU in the future for another build.
