Case fans

[Midnightflyer68]

I'm building my first 'puter. I'm adding 2 fans to the front of the case. Should they be blowing cold air in or sucking hot air out? I have a CPU fan, a fan in the side cover and one on the rear.

Thanks.

Front fans are best used as intakes, moving air into the case, while the psu and rear fans exhaust it out the back.

Thanks for your quick reply. That's how I'll install my fans then.
