I started using this chrome extension / app to manage my passwords for all my mining pools.

Works well, so I thought I'd share it with you.

It's free and runs on Windows, Mac, iOS and Android

Ok so we all know that there are many many different versions of R9 280x cards.

Which one is your favorite and why?

I've got a few scrypt mining rigs with various brands of 280x GPUs and want to streamline with one brand/model for future rigs.

Any and all input is welcome - thanks!

MISSION OBJECTIVE
Ensure cool and efficient mining rig operation with no additional fans or powered sources of ventilation.

ENVIRONMENT
The city I happen to live in has a fairly low winter average temperature. Average daily temperatures fluctuate between 2°C during the day, and -15°C at night (but this last week we've reached -35°C). I wanted to take advantage of this natural weather behaviour and build a mining rig that could leverage the cold outdoors to cool it's naturally hot GPUs.

REQUIREMENTS
I really didn't want to plug additional fans into my motherboard, nor did I want a huge table fan to cramp my rig's style.

SOLUTION
Place rig in proximity of a slightly open window in my office.

RESULTS
Before: 81°C  avg GPU temp
Next to window: 65°C avg GPU temp

INGREDIENTS
one mobo
one CPU
8gb of RAM
three R9 280x
one 1200w PSU
+ one slightly open window


HOW DO YOU KEEP YOUR COOL ?
