front fan set up

[MJS WARLORD]

I have various types of fans on my custom built pc , the build is housed in a cooler master haf x tower. if I put my hand across the front of the pc I can feel a very cold blast of air coming out.
I can also feel cold air coming out of the vents in the top of the case , this air is from the cpu and g card fans. The only warm ( not hot ) air is coming from the vents where the psu is.

My question is this , i have been told that front fans should suck air in and not blow it out , bearing in mind how much cold air i can feel blowing out of the case vents does it really matter if the front fan is sucking air in or blowing it out. I dont know if it is possible to put the fan in the opposite way round but could the pc builder have put it in the wrong way round or does'nt it matter which way round it is.

99% of people will have it bringing in air from the front and exhausting it out the back and top of the case. Front to back works best for most setups.

Coolermaster have an airflow diagram showing what works best for them: http://www.coolermaster.com/case/full-tower/haf-x/

I'd recommend taking that fan out and flipping it so that it's taking air in, no idea why it was changed in the first place.
Check that the fan at the back of the case is blowing air out like the top fans are.
