Hello, last month I bought to electric-tech on eBay for $190 a BitCrane T110 which had both watercooling dead. I replace them with "Cooler Master Nepton 120XL" which are compatible with "Coolit". I replaced the thermal compound with "Thermal grizzly Conductonaut" after having insulated the components around the chip with Neutral Silicon compound. With the frequency set to 725 on /usr/local/bin/page/config/pools.conf.json the T110 run above 1,1 TH/s with the temperature arount 73°C. Then I replaced the noisy fan with the Cooler Master low noise ones and reduced the frequency to 500 Mhz.
Now it run by not making more noise than a PC and gives between 900 GH/s to 1010 GH/s at 77°C which is not bad.
OK now there are Avalon 841 which gives 13 TH/s and some other which gives up to 18 TH/s but there are also as noisy as Fireman Siren.
I think you can get some money by putting them on eBay. There are certainly still a few people who would be delighted to buy them.

Best Regards and good mining !
