yeah, that one is good.
you can only run 3, possibly four, at higher speeds (like 18Gh), so four would go to positions: 1, 3, 5, 7 without interference.
i also put in nearby positions, they fit, but need to be separated by a piece of plastic, like old library card or a store card.
I suggest for you to read up on support thread as there are a lot of important suggestions, especially re software (most succinct software setup writeup was from Jake36).
This is not a money maker, just fun and learning project.
yeah i decently not intresed in making a lot with this build. i just wanting to learn and many make enough to buy a few .cbr comics. the comics are only like 0.0144 Bitcoin for the most expensive ones. so not expecting much from this build except the knowledge. knowledge is power.
Edit: if i only use 4 chips
is the fan even required?
yes, fan is needed for higher speeds=more bitcoin
however, if you already have some household fan, it might be sufficient. I had multiple vornado fans, so i pointed one at the lowest speed toward one of my hubs.
Arctic is a bit tricky as it does not have a power button, so as soon as you plug it in, blades start rotating-this startled me the first time, but even if it hits your hand, it would not hurt, just surprise.
Mine is a little bit overkill but I had lots of computer fan's. So I got a fan controller to control them. It's far overkill but I believe I have 5 fan's I can turn up and down.
I have turned it down now. I was running around 9 compacs, and 3 U3's in my lotto mining and it kept it all cool easily. I recently got rid of a little of some of my lotto gear. I did keep some compacs and use them with RPI. I kept a set as I like collecting some.
