That being said, 1000CFM is a *huge* amount of air movement and, routed
proplerly, will definitely be adequate to cool an otherwise
well-designed system.
Yeah, but if you put some wings on the side of the chassis you can have
the thing float in mid-air and save on floorspace ;-)

Hmmm... could be really simple...

Wikipedia shows conversion chart:


http://en.wikipedia.org/wiki/Conversion_of_units#Power_or_heat_flow_rate

1 atmosphere-cubic foot per minute = 47.820 074 682 24 W

Which is probably close to 48 Watts.

But this is atm-cfm and not cfm hmm... not sure if that is same thing... but
for now I'll go with it ;)

It is not the same thing.

Atmosphere is a unit of pressure. Pressure times volume flow rate is
power, which can be expressed in watts. That's why it is in the
section on units of "Power or heat flow rate."

The design challenge you face is getting the heat from the processor
into the air, not getting the air in and out of the case fast enough.

He won't get it.

Perhaps but there is some pressure going on in the case I bet ! ;)

So I don't trust those "pure" CFM ratings and theory ! ;) =D

Also you guys gotta compensate for intel which lies about TDP !

Add at least 20 to 30% extra ! ;) =D

It's to late now anyway... I ordered 1 motherboard and 1 graphics card...
all cheap stuff... 140 euro's... wouldn't call that cheap but ok.
asrock's 939 + gt 520.

Though maybe I will try CFM in the future once my dream pc back online ! ;)
=D LOL.

What does that mean: "pressure going on in the case?"

It is actually between his ears.

His skull is so thick that being so full of shit is causing his blood
pressure to rise.

"Pressure going on in the case".

Bwuahahahahaha!

Fair enough...

Wikipedia has a nice article on it... it might be of some interest:

http://en.wikipedia.org/wiki/Heat_sink

Bye,
Skybuck.

Yep, rather good. I was especially interested in the "pin type" metallic
airflow heatsink, so I dug a little deeper and did some more calculations.

For what you have, you need about a 3"x4" rectangle with about a
base-plate of about 1/4". The pins should be about 1-1 1/2" high with
about a 3/16" diameter at base tapering down to about 1/64" at the top,
spaced at about 1/4" apart in a square or hex pattern.

The installation is a little tricky, and some improvisation may be needed.

Temporarily place your new heatsink on the top of your head, with the
pins (not the base) touching your scalp. Secure it (temporarily) with
ducttape or one of the silicone-based double-sticky adhesives.

Now, walk out in the nearest "heavy-traffic" street. Wait for a bus to
approach, and if it's not stopping, run out in front of it and bow
toward it, as if aiming the heatsink at the front of the bus.

I think that will cure your TDP heat issues.

Pressure against all kind of components.

Pressure against the air itself, back fan spinning more slowly then front
fan.

Or CPU fan counter acting.

Or obstacles in path.

It does not get any more stupid than you are.
