Here’s a quick update on my Litecoin crate rigs. When I first started running rigs, I have them all over my house, which resulted in my house warming up from the normal 70 degrees fahrenheit to near 80 degrees fahrenheit.
Well, I did upgrade electricity in my garage couple weeks back and moved all my rigs into my garage now and for awhile it was doing fine. When I started adding more rigs to my garage, my garage started feeling like Thailand (yes, that country between earth and the sun)!
Since I live few blocks away from the Pacific Ocean here in SF Bay Area, I knew the simple solution was to pull the cold air from the outside into my garage.
Now, I did a test of also pushing air out of my garage but found it was ineffective as the amount of air to move out of the garage is too much versus pulling cold air in. Now, my garage stays around 75 degrees, just a bit warmer and it’s actually nice in my garage to hang out whereas before it was too cold.
I may further enhance my cooling system in the future by building an enclosed system sorta like hydroponics but for now, the vent fans do good enough job of keeping my rigs under 80 degrees fahrenheit while running near 100% load (on 290X graphic cards doing 880Kh/s each).
If you are thinking about cooling using vent fans, definitely check out some of these vent fans and vent ducts I used. They are really easy to setup, pretty much plug-and-play.
I was using a bunch of regular Honeywell fans before this setup but the problem with that setup is that the garage keeps getting hotter and hotter. The new duct fan setup lets my machines run a lot cooler as there’s actually really cool air being pushed directly to the graphic cards and my garage doesn’t get so hot.
I think the smaller fans or box-type fans work fine for 1 or 2 rigs but once you go beyond that you may need to setup some type of cold air intake (or even pull air out of the room) to make your rigs run efficiently.
Overall, I am doing 22Mh/s with 6 rigs, 4 of those rigs are sitting in my garage each with 5 R9 290X graphic cards. I should be upgrading soon though as I have more graphic cards coming next week and will have an update soon when I have my new rigs built.
In the meanwhile, if you have some great cooling ideas, please don’t forget to share them with everyone else by using the comment box below, thanks!Like my stuff? You can send me coins!
