well got to say thank you EVGA i had a zip file sent to me with two files "fan on" and "fan stops" so can now choose and do tests on which prefer.
so far i am gonna use the older bios, the card now sits nicely on idle at 33'c and during gaming the fan doesn't ramp up anymore, also i like fact if do heavy benchmarks on the card the fan is more aggressive and keeps the card alot cooler, less throttling woop woop
as the card is in my nightblade mi2 pc it has helped alot for a small case when comes to heat
thank you EVGA very happy
