Ok from what i know based on the 5800 that was haulted... the fan would automatically increase RPM when the GPU heats up, and decrease in idle mode! Correct? Just like a CPU fan and motherboard fan... they have sensors that monitor the temps! Well from the impression im getting based on the 6800 vanilla's and/or the GT and ULTRA's, is that the fans are not automatically controlled... Take Leadtek for example, the fan on all three GPU's (NU/GT/Ultra) run at a stead RPM. MSI has a FAN control on the side of the card... which is kind of MANUAL... if the card heats up u gotta open ur computer case and increase the RPM of the fan... not very useful! My question is... are all the 6800's from different manufacturer's (Leadtek/MSI/Gigabyte/eVGA/XFX/BFG/etc)... like that, or are there some out there that automatically monitor the temp of the GPU? I heard that the MSI 6800 Ultra, whistle's while ur booting up windows (as in the fan makes a high pitched noise) and then it goes quite. So i get the impression that the MSI ultra card does get monitored since it increases while boot up?!?! Thnx!
