I care for my cards to stay with temperatures below 55 degrees Celsius with my AC room temperature is 24 - 25 degrees, and i have adequate cooling in my rig.

I have too several hours today but timer says 52 minutes. Where is the problem.

WDC at the 3-3.5 LTC

will think that WDC is better choice for the moment.

Me too mining WDC but cannot sell them. Any suggestions.
