Holy grail for heat control?

otoxotox Member Posts: 41
So I thought I found the holy grail for heat control of my rig, I bought a grow tent off Amazon and ran a vent to outside of my house with an inline blower. The grow tent seemed perfect because it's airtight, has vent holes for venting built in, has air inlet openings that are adjustable, etc.

I bought it set it up, and all is great. Here's my rub, if my fan fails there would be some serious risk of this thing bursting into flames. So while I thought it was a good idea to turn my rig into one huge computer case with negative airflow yada yada I am second guessing myself.

Any thoughts? The one I bought was this: https://amazon.com/gp/aw/d/B01DXYMQ9M/ref=yo_ii_img?ie=UTF8&psc=1

    I like the idea of literally sucking the air away. So how many watts does that blower need to provide enough pressure?. I use metal shelving that I straps the video cards too and a cheapo box fan.

    hmm I wonder what you could grow in there?

    on a serious note it looks fireproof but not sure...im also sure it could be setup that if the fan fails the power gets cut.

    no idea how much air you would have to shift to cool a 1.2KW rig though. them lights look only 400w and that's nothing in a rig :)

    this made me :D . Great idea. Just make sure if your fan cuts out that the power cuts out. Humidity can build up (drops of water on your mobo and rig) and cause a fire. I mean that is what they are made for grow certain plants and humidity can build up. To get the correct exhaust fan you would have to calculate CFM. I don't know it off the top of my head so please google it. Depending on your cfm, it could be an extra 200 plus watts. People who use those tents for what they were intended for using have some sort of ac unit installed also. To avoid that, just get a fan with a CFM way more than you need. (so that the hot air can be sucked out faster) Let us know how it goes.

    Or you can just wait another month for Summer to end...

    thats what i am doing now. cool days r coming. i just put my rig in from of open balcony door and let the vent blow the hot air outside

    its getting cool at night. With a 20$ box fan and an open window. Should be good to go. (at night that is). I avoid the heat by solo mining during the day and dual mining at night. Well at least for now til the temp gets a lot lower.

    Yeah I have a 440 cfm blower on it, it's a ton of air...the room it's in is air conditioned very well, unfortunately it's too much heat for it to handle. Yes, looking forward to winter especially! The humidity is a bit of a concern but I figured with an air conditioned intake, and a high cfm I could pull moisture out quick enough. Cutting the power when the heat gets too high will definitely be an interesting project. I may just end up finishing the room and vent it like a normal person.

    The blower uses about 95 watts. They design them to be super efficient.

    I was wondering when someone was going to post about these tents lol. I run my 1Ghs farm in a 6' x 3.5' grow tent that sits outside on my patio. I use a 10" Can Max (roughly 1300 CFM) fan to extract the hot air out of the tent, a 6" inline fan (600 CFM) to introduce fresh air into the tent and a 8" inline fan (750 CFM) to circulate the air inside the tent. I also open the vents at the bottom and use the other 6" ducting holes on the tent as passive air intakes. I place a weather proof tarp on the "roof" of the tent to catch the rain and then empty it the next day...

    I lost two Biostar MB to the elements when I first set it up and figuring out the weatherproofing. Since then it's been through multiple torrential rainstorms with high wind and heavy rain that have knocked trees down in the neighborhood and the inside remained bone dry. My only concern is the security aspect, but I have multiple outdoor security cameras looking over the tent 24/7...

    You could just buy some heavy polly and make a mini room out of it. That's what I did.(pics are in the Rig Porn page) The whole idea is to contain as much heat as I can so it doesn't spread through the house and extract it. To exact the heat I have a DC furnace fan (set on low) that is exhausting the heat out the dryer vent and furnace vent out the chimney. Its not a perfect solution but it stops my house from crazy hot and the GPU's stay cool enough, so I guess its a success till winter comes and I would need to run the furnace.

    10" Can Max? Can you post a link to that? That's a ton of CFM!

    Sorry it's only a little over 1000 CFMs for the 10" version, but the 12" version pushes 1700 CFM.

    I would feel much safer with two blowers, the odds of both failing are pretty slim...if I have one sucking, the other blowing (no pun intended) then I can get some good airflow with a bit of redundancy.

    Would love to see a pic of your setup...
