So I've had this card ( Newegg.com - SAPPHIRE 100259L Radeon HD 4870 512MB 256-bit GDDR5 PCI Express 2.0 x16 HDCP Ready CrossFire Supported Video Card - Desktop Graphics / Video Cards
) for a few weeks and when I first got it, it was quiet most the time (said ~40% fan) except for the occasional rpm ramp up in gaming. Well after about a week it started to sound like it was ramping up when just sitting at the desktop but the fan control meter in CCC would say it was still at 40% and the temps were always good. Well now the thing is freaking loud all the time unless I manually set it to 20% and even then its louder then when I first got it and it was claiming 40%. I would say the thing is louder at "40%" than my single slot 8800gt at 80% was.
So I was wondering does anybody else have one of these, and how loud is it to you?
Could it be I'm getting false readings and the thing is ramping up the rpm without saying it is? Note if set to auto it idles at 40% and 40c but if I manually set it to 20% it still runs 40c. Also it gets louder if manually set to 50% but typically will not go any louder than that even when set to 100%.
Is there anything I can do to fix it?
