cpu fan direction


OSNN Senior Addict
i have stripped my cpu heatsink to clean it and having rebuilt it i am unsure of the direction of the fan
Does it blow air into the fins or pull the air out !!! :confused:

yep... on the fan itself should be an air-flow direction indicator...

it is advisable to blow air onto the heatsink...

Ep, glad to see you come back and tidy up...did want to ask a one day favor, I want to enhance my resume , was hoping you could make me administrator for a day, if so, take me right off since I won't be here to do anything, and don't know the slightest about the board, but it would be nice putting "served administrator osnn", if can do, THANKS
