Till know I was assumming that CPU fan which comes with processor throws air out from heatsink to cool it till I discover after placing agarbatti near it showed that it sucks in the air. How does that works?

They suck cold air and throw at the CPU, which after contact becomes hot, & then escapes by the lower side holes in the HSF
