Power supply fan?

i own picked a PSU for my new workstation.



I know it has adequate power and things, so i dont need to know going on for that.



But it has two fan, one on back and one on bottom. I be wondering how the coolin is done with PSU's.



Does the admirer on the back inhale nouns, and the one on the bottom extract the inhaled air into the skin, or does the bottom fan inhale the reheat air from the satchel, and the back hanger-on extract it



(When i say posterior i dont mean the spinal column case disciple, i mean the enthusiast on the back of the PSU)



Thanks.



I involve to know this because if it gets rid of heat air next i wont need to buy an superfluous extractor fan.

Power supply fan?

The bottom supporter will suck the warm nouns from within the luggage, and the one at the back will blow it outwards .. u may still have need of an extra case devotee, as the fans within the PSU will run slowly till the PSU itself is hot .. so they won't run faster when ur cpu or mobo is hot .. so its better to get a casing fan.
Bottom hanger-on take the warmness from your processor, and the rear expels to atmosphere
The bottom follower on the PSU will circulate the air through the PSU out the pay for where the power is plugged into so the components will not overheat. So it take the air from the inside of the computer and basically blows it out the back to keep hold of air moving throught it.
