that'snot about a cpu fan....

Pudding enough to tell you that a case intake system will actually heat up the CPU and GPU.

you do understand that that is not pudding right? of course you need to have an exhaust, otherwise you are just cycling hot air, this does not have any barring on this discussion, so it is not pudding.

In the experiment, he swapped the intake fan for the exhaust fan and saw the temperature of the temperatures of the CPU and GPU drop. The control was less efficient than the variable. Pudding.

I thought I was gone...

What that proved was that his/her system cooled. To be puddin', it has got to be that way for any and every system applied. Right?

That's what I'm saying. It's used for transfer, not storage. Otherwise, obviously the CPU would eventually melt. Again, I'm not talking about power. I'm talking about efficiency and the quickest way to get the hot air out and cool air in. Sucking prevent it from going back near the CPU, which is the point. Blowing pushes it back. Yes, both methods will cool a CPU one way or another, but an exhaust system is much more efficient.

This is where I think you're missing the point... Suction is a very localized phenomenon, producing rapid air movement probably no more than a few millimeters behind the fan... The cold air rusing in along the tips of the fins to fill this small depression behind the fan actually traps a bubble of hot air inside the heatsink and effectively prevents it from getting to the fan.

Turn the fan around and, yes you're forcing a bit of hot air from the tops of the fins back into the bottom of the heat sink, but you are also forcing a whole lot more relatively cool air right down into the bottom of the heatsink, where most of the heat is. This in turn results in less heat being conducted to the tips of the fins, resulting in even cooler air going into the base of the heatsink.

You see the air in the case is relatively cool, compared to the temperatures of the heatsink. The goal is to push as much of that cool air through the heatsink as you can... and that ain't going to happen on the intake side of a fan. In fact you would simply end up blowing the cool air away from the heatsink.

its pudding for intake and exhaust, but not for Cpu fan suck pro.

But, but, but... Your whole argument was concerning the placement of the CPU fan. This person's experiment dealt with changing placement of case fans, right?

So, how does that link prove your point?

 

[Product FRED]

Our debate diverged into two separate debates. I just proved myself correct in stating that case exhausts are better for overall circulation in a case than a combination of exhaust and intake (unless the intake is in the front), as previously suggested by someone else. At least we can all agree that it depends which part of the computer we're talking about.

that'snot about a cpu fan....

Didn't see this earlier, but to the point.

You guys are confusing everything by going off on tangents. I would think the more efficient cooling would have the fan pulling air out of the sink with new cool air following in behind it and the case fan pushing the heat out.

 

[win7clutz]

Surely this has strayed Off Topic!

The OP's question was

Is my cpu fan better as intake or exhaust???????

Fred's response was:

The CPU fan should blow away from the heatsink to pull off excess heat. This also helps draw air across the cooling fins. If you have a rear fan, then the heat that the cooler is blowing away gets exhausted from the case.

Therefore, the immediate response to the question was incorrect. But with that said, this discussion went OT and now has little significance to the OP. But I'm sure many have enjoyed posting their views on Case Cooling.

Challenge Intel and AMD with that...

and cool master and every heat sink manufacturer ever

Believe me it isn't... Go back to my first post in this thread... simple example...

Moisten your palm... hold it a couple of inches from your mouth, breath in as hard as you can... Did you feel it cool your hand? ... no you didn't.

Moisten your palm... hold it a couple of inches from your mouth, breath out as gently as you can.. Did you feel it cool your hand? ... Yes you did.

It really is that simple... You want to move as much cool air through the hot spots as you can.... and suction just ain't gonna do it.

Anyway... I'm starting to go in circles. Have fun guys... I'm gonna switch to read-only from here on.

In your case the water is the heat sink, yes? If the CPU were your tongue and the heatskin was the water, on your tongue, sucking would be cooler, not blowing.

Fred, my friend... Why not just admit you made a mistake?

Really... every production heatsink/fan combination, including the ones that come with the CPU has the fan blowing air down into the heatsink fins. Believe me, it's done for very good reasons, as I've explained...

 

[Product FRED]

I did not make a mistake. As I stated, both means will cool a system.

Hey guys, i tested it leving my pc to idle etc.

Lets see what you think, why not try it your selfs.

Just mind Fred is not here to have the piss taken out of him.
