Tried using 80% fan speed and about 6 out of 20 fan died after 3 months.... is it because of the sapphire brand I am using?
I am running my Sapphire HD7950 at 85% fan speeds. Does that mean I should be worried, too?
Different manufacturers have different issues, and will invest different amounts into the quality of their fans. I know currently MSI has several issues with their fans. I've used the Gigabyte WF3 coolers, and never had an issue with the fans.
Thanks. I live in warm climate, so scrypt mining on my Sapphire 7950 card runs quite hot. If I try to mine with its full capacity (600+ khash/sec), then it goes above 90˚ C even with the fan running above 90%
So I am undervolting it to run at 500 khash/sec which keeps it below 75˚ C and the fan spins at about 80%
