Hi guys, is something curious what is happening to me, but that together you are going to get help with what I get. This monday I have received my two new Club 3D HD6970 dual fan version, specifically dealing with this model shares sink to the series Powercolor PCS in principle a guarantee. Before installing the new card drivers uninstalled the 5800 series had and cleaned the register with the Driver Sweeper in Safe mode. Well, install the two new cards, I put the CrossFire bridge and start the system, and them the appropriate drivers, in this case the later 11.1. Restart the computer and start making the typical sound of spinning fans have plenty of rpm and normally removed in the operating system starts to load, just a few seconds ... Well, the noise so loud that fan is not gone in no time and that makes me very odd, since it is a sink that as I read is the quietest in the market, particularly is this (the same as mounted the PowerColor PCS + + 6950). The GPU-Z detects both cards perfectly: Temperatures and the% turnover of their fans are right, nothing unusual: In this review of driverheaven.com they analyze the Powercolor HD6950 PCS++ and say it: "Temperatures on the PowerColor Are lower at load and idle, as power is used. For Noise Levels, this is Impressive Another aspect of this card. It is the quietest 6950 We Have Used So Far." So I wonder ... Would it have to update the BIOS or at least edit the profiles of the fans in it to make it look like the model Powercolor?, if so, what software should be used to do, how could he know or put values where I can get the values of the profiles of model fans PowerColor PCS + +? IDLE GPU1 GPU2 ...and even these values are very noisy ... Am I missing something? Fans at 100% with the MSi Afterburner, curious results by GPU-Z, the fans are al full speed or only at the % that this screens shows?: GPU1 GPU2 With the fans al 100% by Afterburner, the AIDA64 tells me that: And one last thing ... can go wrong all these monitoring programs at the same time? Even at this time this capture shows all fans speed is 0%, but it's untruth, I estimate that at least about 800-1000 rpm at this moment: Can anybody help me please???
