How to clean my power supply

[ilayg6]

Lets say i have a canless air system
And i want to clean my PSU with it.
Now my PSU is placed on the lower side of the case and not on top,it has 2 holes,1 of them is getting air from beneath the case which is where i believe the fan of the power supply is,and the second hole is getting the heat and air out of the case.

Sorry if i was not 100% clear but its hard for me to explain it clearly.
From which side will i need to clean it from?
From beneath the case or where the heat and air comes out of the case?

Every comment will be appriciated!

Here's how i'd do it: Take the PSU out of the PC and secure the fan so it wouldn't turn when blowing air into the PSU. Position the PSU so that the fan faces downwards and blow the air in from the rear of the PSU (where the PSU switch is). Any dust that is blown loose would fall downwards by passing the PSU fan.

Can i clean it without getting the PSU from the PC case?

Well, you could but the case's bottom fan grille (and filter) would be additional restriction for keeping the dust from escaping. Also, if you keep PSU in place then there's no way you could secure the PSU fan so that it wouldn't turn.

I can remove the filtee no biggy but i just to know like,if i just do some tiny air shots on the power supply from the rear(where the button is)
Will it remove most of the dust or the dust will stick inside the PSU?

Dust isn't sticky by nature but you need to provide powerful enough airflow jet to the dust accumulation spots to loosen all the dust.
