Possible Overkill? Old Trunk Litecoin Mining Rig

[hendo420]

My ac went out so I had to macgiver this shit.

I took an old trunk, like the kind your grandma keeps at the end of her bed and fills it with blankets and stuff. I attached a furnace blower (squirlcage fan) from a fullsized house furnace. I then stuck my 2x milkcrate rigs inside. I have a hole in the opposite end. It pumps so much air its crazy. I put the hole thing out on my porch that is pretty open, lots of windows. Even at 100f outside the hottest card is only 83c and the coldest being 64c.

I'm going to make some custom mounts with 1x1s in the box and put the components directly in the box, this should allow me more cards and more boards. I'm thinking I could put atleast 12-15 video cards in that old trunk and keep them all below 85c at 110f outside.

Good job you even thought about air filter. Only disadvantage I see is that this kind of fan draw a lot of electricity.

I don't have a meter but my estimate is that its pulling around 300-400w. Its less than my window AC unit and it does 700w. I am going to install a dimmer switch so when this heat wave lets up I can turn the blower down. I think once I optimize everything and get all the components out of the crates I will be able to run the blower as low as 30-40% which should cut power usage alot. Its still cheaper than running it inside and having the AC fight it for sure. And my room is now a nice 75f

Wattage should be written somewhere but maybe the sticker fell. You are right air cooling should be cheaper than an AC.

I mocked up my future upgrade in tinkercad. I can fit 16 cards in this Old Trunk.






Edit. - I forgot to add in the power supply's. lol
