Imma not selling my precious
![Wink](https://bitcointalk.org/Smileys/default/wink.gif)
But they are quality product they stay much cooler then other simple designs often even beat 3 fanned model cards cooled ones
Possible very high overclocks also because of the prefect cooling.
But i allready know for a fact that really kills your cards in time much quicker then if kept at certain speeds
Mine runs perfects at 1050 core however i ran them for many months at 1190 however i lost one now because the could not cope the heat from mining constant for almost 2 years.
I mine full at scrypt at around 68 C and that is not even with using fan setting at 55% it fully runs on auto fan speed.
Ofcourse on hot days when its 34 to 36 C it breaks the 75c mark but hell these cards can handle it with ease
As you ofcourse know if you put more into a case they heat each other which will effect the performance
