Have a Corsair 250 D and a Seasonic SS-660XP2, do I place the fan facing the bottom of the case or upwards inside the case?

Hello world, I have a Corsair 250 D and a Seasonic SS-660XP2


Question is, do I place the Seasonic power supply with the fan/exhaust facing outwards from the Corsair 250 case or do I have it sit upright facing into the case?


I ask because there is a grill on the bottom of the corsair 250 d case specifically for a power supply exhaust fan to face, but I've been told seasonic power supplies need to be sitting upright where the fan/exhaust is blowing up?



Because this is a mini ITX case, there is not much room and the fan of the power supply would be blocked by a wall

Most people will say it's just preference (which it is) and some will say it affects temperature (which it can)etc

I have the same power supply and I have it facing downwards (fan facing the outside). Have done this for all my power supplies.

You have a fan filter with the 250D's PSU location so you'll be all set to go with the fan facing towards the outside thumb.gif

Edit: Included a quick picture below to show how the vast majority of PSUs; exhaust/intake works.

All PSU fans are intake, so make the fan facing the bottom so that it's pulling in air from underneath the case. The only time you don't want to do this is when the computer is sitting on medium to high-pile carpeting. If it's on typical high-traffic carpet found in an office building, then it's fine. Bare floors are even better.

It depends also on cable length I have a 860i and a 780t both corsair products but my 8 pin CPU cable won't reach the MB with fan mounted down.
