Hi guys,
Well it seems like these stupid 5850 Xtremes have really crappy fans

, I just noticed my video card was over heating and didn't hear the usual whine it makes. I popped open GPU-Z and noticed the fan was at half the speed of my other 5850 Xtreme. I then tweaked around in Catalyst and GPU-Z hoping it was just a mistake but it really seemed this 5850 could not go over 2500 RPM at 100% whereas my other 5850 hits 4500.
After pulling the card out, I noticed it was extremely stiff to get the stupid fan to move compared to my 5830s, the other 5850, and my case fans.
So I am thinking it is a seized bearing that needs to be lubed but I don't want to risk warranty. The crappy thing is I already paid $20 to RMA another 5850 earlier, and I will be paying likely another $20-40 (with Canada Post striking) and waiting 6-8 weeks to get another card (if any). I just bought these cards last month but it is slightly over the 30 day return period.
Any suggestions on what to do or options that don't void the warranty but might fix the problem?
