I can 1000000% understand your fan speed concern. I just went thru this hell and total game stability was in theer due to 90+c temps on my GPU's. Download a program called Rivatuner 2.06 (http://downloads.guru3d.com/download.php?det=163) by using this program, you can manually adjust the fan speed and it work AWESOME
. I have both of my cards using the 75% fan setting 100% of the time, I have both my 3870's @ 860c 2.54GHz ram. My idle temps are 25-28c, load temps are 45-52c
My games all run perfectly, no freezes, hiccups, nothing, just pure gaming fun now. If you have a crossfire setup, make sure you set *BOTH* cards fan speeds, cause adjusting 1 card, will not adjust the *OTHER* card. In the first screen you see when Rivatuner starts, click the drop down arrow, and select the OTHER card, and repeat the same process you did for setting the fan speed for your first card. Make Sense? Let me know if you need more help. Good Luck
