Hello,

I'm curious if it's possible to build a powerfull PC/iCore/GPU/Cuda PC
without getting into heat problems !

For example CPU has about 30 TDP (which is close to watts, otherwise find
watts listing) and GPU could have as much as 200 to 300 TDP (watts) (top
model for maximum bandwidth).

Additional watts for memory( 20 watt ? just guessing ) /motherboard (10
watt ?)/4 harddisk (60 watt*4=240)

Let's say 800 watts.

How much CFM would be needed to get rid of all that heat ?!?

A CFM heat (PC) calculator would be most handy... maybe somebody can
make/program it.

What would be good formula's to use ?!?

Bye,
Skybuck =D

Hmmm... could be really simple...

Wikipedia shows conversion chart:


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

So (800 * 60) / 48 = 1000 CFM needed ! =D


Let's see if antec case is sufficient lol:

http://www.antec.com/pdf/manuals/1200_EN%20manual.pdf

It's about 240 CFM...

So there is no way that the antec 1200 case would be able to cool such a
system sufficiently.

Yes perhaps the graphics card would output a little bit of air as well...
but it's waaayyyy too little.

And this manual probably assumes at maximum operating fan speed... so let's
divide 240 by 2 is 120 CFM... and let's divide it one more time because of
dust is only 60 CFM.

Yeah...

Well it's pretty clear where this is going:

OVERHEAT DAMAGE ! =D

Bye,
Skybuck

Static pressure:

More interesting stuff:

Bye,
Skybuck.

More interesting stuff, in case my calculations are off, but pressure does
play a roll as does temperature of air:

Bye,
Skybuck.

Really interesting stuff:

Getting down to basics now lol... getting down to the core of it ! =D

Bye,
Skybuck.

Interesting website:

Bye,
Skybuck.

Most interesting part so far, and most interesting website so far:

It mentions CFD analysis.

Why calculate one little simple fokking formula if you can simulate the
whole system ! LOL.

What hopefully CFD analysis software ! =D

CFD:

Csomething Fluid Dynamics LOL.

Bye,
Skyflow.

This one looks cool:

And the pirates have it too !

Har Har Har ! =D

Doei,
Skypirate ! =D

This one also seems kinda cool but a bit old, but that could be an
adventage, since I am on a PIII 450 mhz and best of all it's free, alas
only for MAC OS and Linux:

Could still be interesting though.

Bye,
Skybuck.

Yeah,

I heared about these motherfokkers too:

http://www.ansys.com/Products/Simula...mics/ANSYS+CFD

They've been around for a long time... maybe old maybe not old maybe good
maybe not good...

So far it's a bit vague...

Butt the pirates have it too ! =D

Bye,
Skybuttpirate ! LOL.
