Hey, guys. I've been doing some experimenting with techniques to make mining rigs easier to build and cooler. I found some products that worked for me, and want to offer them to everyone here.
This is a short PCI-E riser. Put one of these in a PCI-E slot, then put the card in the riser. This allows more airflow between the card and the motherboard. It's tall enough to add roughly 3/4" additional space, but short enough to stay sturdy.
On one of my systems with 4 6950s, using these to stagger the height of every other card, the overall temps of all 4 cards dropped around 6C, which allowed another 8% overclock.
0.35BTC each, I have about 20 left.
This is a pretty rare PCI-E power adapter, letting you use a SATA power connector from your power supply instead of the annoying old style Molex connectors. Converts a single SATA power connector to a 6-pin PCI-E connector. Don't fight with splitters or poorly fitting connectors, these slip in and lock securely.
0.30BTC each, I have about 30 left.
Very high quality dual molex to dual 6 or 8-pin PCI-E connectors.
0.30BTC each, I have about 10 left.
This is the craziest case fan I have ever seen. I plugged it in to give it a test before screwing it down, and the torque from the motor made it jump across my desk. It's heavy, well built and moves more air than I thought possible. 2 or 3 times the airflow of the previous "high performance" fans I bought, and roughly 5x the CFMs of the best fan that the local computer parts store sells. I bought more than I ended up needing, because they worked so well.
1BTC each. I have 8 now, can maybe get more.
Free shipping with orders of 3BTC or more to anywhere in the world. Send me a PM here if you're interested in any of this. I'll ship immediately after receiving payment.
I'm happy to answer any questions, or take any pictures/measurements to see if they'd work for you.
