Fan up or down?

[itrue21]

When placing a Power Supply into a computer, for the best air flow and longer life for the power supply, do I want to face the power supply fan up or down?

down, then it will suck up cold air rather then sucking down hot air

Depends on estetics and user preference. If your case doesnt got a good airflow or at least positive pressure (more air coming in that out) then PSU fan down, because hot air gonna go thru PSU and make it work harder. If you got good cooling (airflow) inside and/or positive pressure then it depends mostly how you want to. I personally put it down.

i remember tiny tom logan doing a video about it and how either way does not matter at all except when the fan is up if you drop a screw you may be in for trouble

Can you make a topic in the New Builds and Planning section, there you could ask all of the questions you have in there instead of making a new topic for each question every 5 minutes.

Down is better for the psu. You don't want to do this if the bottom of the case doesn't have ventilation or filters though.

Up can take heat away from the gpu or the rest of the system.

 

It usually doesn't matter. Also, this really only applies if your case supports a bottom mounted psu.

Thank you that is the information I was looking for.

if you are going to be placing the pc on camrpet then put the power supply up because if you put it down the psu will act as a hoover and get really dusty however if it is not going on a carpet then your best bet is down

Mine faces the back of the case and blows out the top, SilverStone FT02 messes with all your heads.
