CPU fan direction?

[snidy1]

On a test at school it asked what direction the fan should blow, I said into the cpu and I got it wrong. I've always heard that it should blow into the cpu. Am I wrong or is the teacher a dumb@ss? If I'm right, is there somewhere on line that I can get proof for him?

I've done my own test and when the fan blows away from the cpu I get faster and cooler cooling.

I think that question had a lot to do with your teacher's personal preference.

It really depends on the heat sink. Some are designed for the fan to blow on them while others are designed to have heat pulled off of them.

Teachers a dumb @$$! There is no right or wrong answer. Mainly because it all depends on the design of the HS and hte power of the fan you are using.

So far, on all the heatsinks I've had the cpu temperature was cooler with the fan blowing toward the sink.

teacher=dumb@$$

(tell hesheit that for me haha....the "hesheit" is from my phsyics teacher, he doesntlike to "exhibit preference" over a certain sex, so thats what he writes on all quiz's lol)

anywyas,
1. it depends on the design of the heatsink
2. it depends on each individual situation (unless you havel ike 400 computers EXACTLY the same)

alpha heatsinks i know are designed to have heastink suck air away from cpu, most others are designed to have it blow air onto cpu

sometimes it ends up working better contrary to "proper" directions

that question is just bs, and the answer isnt justifiable for just ONE correct answer...meaning he cant say "this is right way, that is wrong way"

That's what I thought
