I am trying to use this to blow out the hot air in my warehouse. I have tried many different positions but the temps seems unchanged I may doing this wrong way or wrong placement Anybody has seen this in action?

Do you have more information on it? CFM? Circumfrence? 65 metre square per minute https://www.horme.com.sg/product.aspx?id=2915so a little over 700 CFM any suggestions? I now plan to move the unit near the window blowing out and extend the hose to the hotspots, currently it's the other round. The last time I did this -- no change in temps and I am stumped - it was suppose to work. I am trying it again this time with some extra box fans to move the air around a bit more. Also.... there may be some impact on static/non static pressure here - I am not good in this topic and any help will be greatly appreciated. Thanks

the one that I got is 300mm (the largest one they have) and 2800 RPM and 10m hose sold separately.

what air comes in? you may need a second unit on to pull air into the warehouse.
and if a recall it is hot where you are.
So if the air temp is 100f in the warehouse and the outside temp is 100f
temps will not drop a lot but the temps in the warehouse may not raise to say 105f
fan cooling helps but when it is really hot you don't drop a lot.
My solar array was at 95f when outside temps were 95f but no fans and I went to 100f
these temperature behavior by using fans is what i'm experiencing...fans can only do much, we have to find a way where we can direct the heat or make the heat transfer to. Planning to install swamp cooler in my mining room before summer begins.

Thanks Phil for getting the bigger picture into perspective _ I now know what I'm up against.
38-39c is 100F, so I am nearly at the limits.
The GPU rigs are still OK overall .... but 2 rigs 5x390s and 6xRX480 rigs are acting up due to Claymore stopping a GPU from overheating ... then the whole rig stops mining.
I dread the time to go back to ETH mining because thats where temps and power goes up.
I think I will stay mining ZCASH for awhile more, then if that fails.... XMR, then last resort ETH with lowest intensity.

OMG - whats that ? the concept is the same with the evaporative cooler fans that can be bought at the dept. store.. Swamp cooling is like utilizing water to cool your area/room/garage....you can google for more visuals and explanations

Sorry for the off topic comment, but I see this site has a few different size fans. They have an 8" 12" and 16". Any idea why the 12" has a higher CFM rating than the 16"? A fan like this could be useful to me in moving heat around to more needed areas this winter.

I am trying to use this to blow out the hot air in my warehouse. I have tried many different positions but the temps seems unchanged I may doing this wrong way or wrong placement Anybody has seen this in action? How is exactly your warehouse ? Has it open windows ? Do you have access to a source of fresh air ? Another possibility would be blowing that fresh air directly on the cards, even if I'm not sure that it will work. A solution, complicated, I know, would be to create a network of fans that would push the hot air into a funnel, connected to that machine.

The way it can work is if you have an attic like or a side of the building where you can throw the hot air...that place where you throw hot air should not find a way back and the wall is heat insulated for maximum performance...and then the fresh air comes from the other side, preferrably the cooler side, and just like what phil said the new/fresh air should be cool enough because if that air is just a little bit cooler you may get only a slight decrease in temp

Doesn't significantly matter - the amount of heat input it takes to make water change phase from liquid to vapor is over 500 TIMES the amount of heat input it takes to raise the temp of the same amount of water 1 degree C. A few degrees difference in the temp of the water in the tank of an evaporative cooler doesn't matter enough to notice. Humidity of the air being cooled via an evaporative system matters a LOT though - they work a ton better in areas with dry air than areas with humid air. Kuwait loves them, Malaysia would find them pretty much worthless. CFM on a fan is a function of it's RPM, diameter, and efficiency. A smaller high-RPM fan (think Delta 60x25mm screamer like some CPU coolers used back in the day) can blow more air than a low-RPM higher diameter fan (that 60 CFM screamer turning at around 8000 RPM blew more air than a lot of 120mm fans). If you expect a fan to blow hot air out of a space (or cold air into it) you have to have somewhere for replacement air to get into / out of the space. Doesn't do any good to set up a vent fan if there's no other way into or out of the space.

Humidity of the air being cooled via an evaporative system matters a LOT though - they work a ton better in areas with dry air than areas with humid air. Kuwait loves them, Malaysia would find them pretty much worthless. running mining rigs makes the air in my mining room drier than the rest of the house, the water i spilled on the floor evaporated quickly, it is quicker to dry clothes in my mining room compared in drying them outside, and a portion of the room becomes cooler when clothes are being dried. I defrost stake in more or less 5 mins ...those observations for me makes me think that swamp cooling here is feasible..i may enjoy the cooler climate now but i know what summer will bring to my mining room i have no way of measuring humidity here but based from my observations above, a constant pump of water to the cooling pads or columns of towels(custom made ) and a fan would make a difference here. i haven't researched more about humidity but i think humidity or water in the air helps GPUs to transfer more heat to the air just like how water in the radiator helps transfer heat from the car engine to the radiator..
