So i got a HD3850 for christmas and ive been overclocking The way these cards are set when you buy them they set the fan to always run at 25-35% speed for no noise but it gets temps of 70-85c which is normal. well with riva tuner i found it if i put it at 80% it stays at 40-50C while gaming and also if i put it at 100% AND OVERCLOck it from 669/829 to like 730/950 it stays at like 60cim wondering how much this will take away from its lifespanand how long it will last now?btw this is all on stock coolingalso if putting all my fans to 100% or 80 or 90 % while gaming how much lifespan does it take away from the fans and even thow i voided my 3850 warrant if the fan ever stopped working or it broke could i pay to have it fixed?
