I keep the warehouse at 88F.  My 15,000cfm blower is going in tuesday to remove the heat.  I actually have 60 tons of AC already installed but I don't turn them on because they use too much power.  I use 1 AC unit to keep the building at 88F during the day.

What kind of blower is that?

Any idea of how much KW it might be able to cool?

15,000 cfm = 15,000 Cubic Feet per Minute. That's how much air it can blow. It is not for cooling, it is just to remove the hot air, exactly 15,000 Cubic Feet per Minute.

Removing heat = cooling.

Every air cooled datacenter needs X amount of CFM to keep Y KW worth of hardware at Z degrees.

No.

Removing heat = Removing hot air from the building
Cooling = Cooling the same air and circulating it back

Can't make it simpler, sorry.

cool
ko͞ol/
verb
gerund or present participle: cooling

    become or cause to become less hot.

I'm not going to argue about the semantics. But every method of cooling you can think of involves removing heat via air (or sometimes liquid).

My last try to fix your ignorance. Search for the meaning of the word CONTEXT, that will give you some small chance to understand what I did meant. Other than that, I am helpless, sorry.

guys...you are picking nits here

moving air around has a cooling effect, especially since miners operate at temps that are generally above even the highest ambient temps...unless you happen to live in Death Valley or Aziziya

if you let the air get trapped in a building or room, the miners can quickly raise the temps to really high levels...exhaust that hot air and also bring in fresh, cooler air then you can maintain stasis

it is "cooling" even if it is not using some sort of refrigeration mechanism to do so

Im siding with jimmothy - he knows enough about how removing hot air works to reduce operating temperatures of hardware (assuming the air flowing is in a lower temperature than your exhaust, either by A/C or simply cooler outside air) that to say that removing heat isnt cooling is silly.

lets rephrase the question: BEFORE and AFTER adding the blower to remove hot air, what is the difference in heat production (aka power draw) that the building can handle under the same conditions as before? obviously theres a dozen factors like placement and direction and power draw of the blower, but a rough number is enough. can you handle ~30kW more equipment than before? 50kW?

24" PCI-E cables with 16AWG wires and stripped ends - great for server PSU mods, best prices https://bitcointalk.org/index.php?topic=563461 also selling 6" M-F-M PCIe splitters and PCIe-PCIe

No.

Removing heat = Removing hot air from the building
Cooling = Cooling the same air and circulating it back

Can't make it simpler, sorry.

The issue is complicated by the fact that the incoming air is the same temp as the ambient, and the internal air is being dumped outside.  The real question should be what is the heat capacity of those 15000CF that is being removed. That depends on air pressure (elevation) and water vapor.  It's a little complicated unless you do that stuff for a living.

If the 15000CFM is able to bring in enough "cool" air from outside and the hot air can rise to the top of the warehouse it doesn't really matter.

Well I am using a Helios KRD 500 wich pulls around 5650cfm and "drains" my pocket with 1,72kW so you do the math.


My fan is more than enough to cool 100 ATI Radeon 280X/290 cards on SCrypt, I can bet it can cool twice that, if I had better air ducts (im using a 50x50 air duct and a adapter)

dayum...why didn't ya just get a cheap attic heat exhaust fan like me? 1300cfm should be nuff to vent the heat of those cards...it's handling 4kw heat for me Grin How loud is that thing?
