CPU Fan, which way to point?

[ironhell]

What is the optimal direction to position the CPU Fan? Is it to point it such that the air is being pushed onto the CPU (or rather the heat sink) or do I want to point it so that the air is being pushed away from the CPU? Thanks.

 

[scottchen]

Pushing air onto the heatsink covers the most area. So it's best that way.

Hmm, okay, thanks. Do you have the problem where your heat sink gets clogged with dust now and then? I just spent half an hour cleaning my heatsink... Thanks.

 

[error_911]

just like the majority of exposed things, they get dirty and need to be periodically cleaned (unless you run water cooling like me )

to suck or to blow, such a paradox...

Personally i like it when they blow...

They should make a solid silver heatsink that uses 120mm 190CFM delta fan.

You should try it, cut a small block, use it as your CPU waterblock.

hmmm.... flat square industrial daimond maybe?

cant use silver in a waterblock anyway... corrode too easily unless you use alot of corrosion inhibitor

ya diamond is just ultra compact carbon...it should do very well.

Where's Plastic? I thought that would be on top.

From Wikipedia
<A HREF="http://en2.wikipedia.org/wiki/Thermal_conductivity" target="_new">http://en2.wikipedia.org/wiki/Thermal_conductivity</A>
Thermal conductivity of other common materials:

Silver 430 W·m-1·K-1
Copper 390
Gold 320
Aluminium 236
Platinum 70
Quartz 8
Glass 1
Water 0.6
Wool 0.05
Expanded polystyrene ("Styrofoam") 0.03

Thermal conductivity changes with temperature. For most materials it decreases slightly as the temperature rises.
Since diamond has such a high thermal conductivity, natural blue diamond much higher still, one may test gems to determine if they are genuine diamonds using a thermal conductance tester, one of the instruments of gemology. Diamonds of any size are notably cool to the touch because of their high thermal conductivity, perhaps the origin of the term "ice."

Hehe, most plastics are insulators.

Oh, I didn't know that, I was just making myself a nice plastic heatsink with a nice compact 150 fins.

Ok, I'll shut up now. What I found funny was that one of my neighbours used copper for their roof?! how great is that. At first it looked nice and shiny, not it looks like a piece of sh*t, since where I live rains a lot. I bet those things are great conductors, so in the summer it'll be boiling in his house, and in the winter, it'll be f*cking freezing.
What a brilliant guy my neighbour is.

Copper is a great heat conductor, but I don't know about copper oxide.

Make sure those fins are very close, like .005 inches apart.

Unfortunately, some plastics don't melt.

what no ceramics...

The ceramic package of my 386 and 387 sitting on my desk are always REALLY cold to the touch.
