You feel that thrill because you haven't experienced this mining shit at worst when shit literally hits the fan. Because for me it just happened again. Another fan broke from R9 280X. This hardware just ain't going to last full throttle use for years, few months maybe if you're lucky. Then you can wait weeks to get a replacement from warranty. I have one card already returned and now i have to go return this one too. Or you can spend for high-end cooling which by the way will cost money.
I didn't return the 2nd one and bought Arctic Accelero Xtreme IV 280X package for it. And it works so well and runs so cool now. Only 50C at 75% fan settings, the rig outside and +20C weather and crushing numbers full throttle. Not too hard to assembly but of course you will need some basic tweaking skills like holding a screwdriver and patience. Highly recommended if you can afford it or find one cheap.
