For your "bearing" issue, I don't experience a very loud noise with my TF4, maybe some dust or a wire hitting on yours... dunno.
Also don't forget that you can always edit your fan profile in the settings/fan tab of msi afterburner.
I didn't mention the dust removal thing. I do like that, though they claim it does it for around 30 seconds, yet with my card it happens for no more than 15, then stops, then ramps back up to 100% in the proper direction, basically sucking back in all the dust it just removed. Again, bad design from MSI.
I heard Gigabyte also has the dust removal technology too, wonder if it works better. Reports say their card can run around 7C cooler under load also, ouch. Wonder what the acoustics are compared to the MSI..
Anyway, the noise isn't loud at all at low RPMs. I can't really hear it when the fan is at 30%. I really hear it when the fan is at 100%, but you might not even realize the noise is there unless you single out that specific tone. An easy test is to ramp the fan to 100% then stop the fan closest to the I/O (or toggle between them if you don't notice a difference). If you hear a tone difference (ie. whining removal), chances are your fan exhibits the same problem as mine.
Seeing as this issue has happened on all 3 video cards I've owned from MSI (though the Twin Frozr 2 ones were really bad), I'm pretty sure it's a design flaw with the Twin Frozr design.Edited by DAOWAce - 8/20/12 at 5:37pm
