Before I placed the 2 80mm fans, I was getting 79C for the top card and 81C for the bottom card. When I suspended them so that they were blowing inbetween the s, I got 79C for the top card and 80C for the bottom card. This was probably because my cable extensions restrict the airflow coming from the fans. I then put the 2 80mm fans where they were pictured, and got 79C for the top card and 76C for the bottom card.
So this placement helped a lot with temps on the bottom card. So then I tried this fan configuration. I bought 3 mm fans to replace the mm fans I had for exhaust. I also tried to reposition my cable extensions so that they wouldn't restrict airflow inbetween the cards not pictured.
With this setup, I was getting 76C to 77C for the top card and 75C for the bottom card. In terms of the 80mm side fans, I also tried pointing the 2 80mm fans so that they were sucking air away from the GPU, but this made the temps a lot hotter. I also tried positioning the 3 mm fans so that they were blowing against the 2 mm intake fans makes no sense, but I wanted to see what would happen and that made the temps hotter which was to be expected.
So in summary, if you want better cooling, you might benefit from adding fans inbetween your intake fans and your GPUs so that you get more air blowing on your GPUs. If you have a case with a side intake, these experiments might not apply or you might have to configure your side fan differently to optimize airflow. Some flaws in these experiments is that I'm not using the best fans for my setup. This pcpartpicker list includes my fans. If I really wanted the best cooling, I would have gotten the best fans for each size fan, but I couldn't afford it and hell, if I could, I would be spending closer to a water cooling setup.
Of course I still wasn't happy with my temps, so the next thing I tried was replacing the thermal paste on the GPUs. The results will be in another thread if this one gets enough attention. I guess this might not apply to all in this sub because the more important things in a mining rig are adding as many cards as you can and blasting them with a box fan, but this might apply to those who have a primary PC that they also use for mining.
This is a xpost that I posted in buildapc I made this crossfire build a couple months ago, and since then I've been trying different things to try to bring down temps on my graphics cards. I decided to go with the X motherboard because it was cheaper than the FX board, and the X board had a combo deal going on with the I just went with the X board because of money, if I had a few more dollars I would have gone with the FX board, but I'm not too bummed about that.
Other than that, I do all kinds of things, it would be too long to list, but that and bitcoin mining, I'll definitely be utilizing this rig to it's limits. Common coin is SIA. I am going to leave card speed off on this one since it is dual mined.
Otherwise, I won't be able to continue open-source development. Last edited: Apr 26, Joined May 8, Messages 0. Updated some things, will add more information as I move on.

Very useful and full of info Even see some driver versions in there too, brilliant. R-T-B said:. You can find the whitepapers for most of the hash algorithms with some legwork.
The idea is that Bitcoin miners group a bunch of Bitcoin transactions into a block, then repeatedly perform a cryptographic operation called hashing zillions of times until someone finds a special extremely rare hash value. At this point, the block has been mined and becomes part of the Bitcoin block chain. The hashing task itself doesn't accomplish anything useful in itself, but because finding a successful block is so difficult, it ensures that no individual has the resources to take over the Bitcoin system.
My point of view of the cryptocurrencies remain the same then. Most of them don't do anything useful beyond securing the network. LBRY might be the exception it runs a peer to peer media platform , as well as a spattering of blockchain storage solutions.
There are quite a few coins that do useful things as coins. Joined Jan 25, Messages 1, 0. From the title I was expecting a Linus Tech Tips video. I'd be interested to learn if you can elaborate. Besides the two types I stated? I'm admitedly out of date on this but I'd be interested to learn if you can elaborate. Did some updating.
