I guess people will always have simple questions about hardware so let's post your one liner questions here.

Free for all.  (that means anyone, seniors and noobs alike can ask super stoopid question and not get whacked / flamed / scolded  harrased / killed / whatever by any forumer - just in this thread)

Other oneliner and "I-refuse-to-google" threads will be deleted without mercy

To those who flame others for asking stoopid question will get their share of flames, no question asked

Guys, here noob a question:

Could I change my heatsink fan(so noisy!!) without changing to a new processor?

that's what i do.

it doesn't make sense to have top as intake, as that would go against the law of physics of hot vs cold air movements

it doesn't make snese to have fans on the lower side of the casing as exhaust either, as that would mean that cold air are taken out. and again, it's not using the law of physics to help the system.
