Please answer this Q reg. SMPS

[gameboy83]

Hi Folks,

I am planning to buy a 600W SMPS for my PC. When i check the SMPS pic, the fan is pointing downwards, ie. when placed in a cabinet, the SMPS fan will blow the air into the cabinet. Will it cause any temp. increase and if so, what should be my side fan direction to counter it
