Default Re: Absurd and arbitrary HDX fan noise

Hello,

Quote:
Is there any measurement for the record? Hot for your hand is not necessarily hot for the card.
Not publicly published. As I stated some time ago in this thread, the firmware that runs the fans is programmed too conservatively on at least some of the cards in the sense that we've done thermal scans on all the chips on the board before and after the fans come on, and on some cards they come on too early. The units we tested, admittedly only two cards, had no ICs or other parts anywhere near thermal issues when the fan turned on. They also do not pwm the fans, they are off or full speed.

Perhaps set too conservatively to accommodate a variety of operating conditions?
Perhaps set too conservatively on only some cards?
Perhaps set too conservatively because they didn't think anyone would mind the extra precaution?
Don't know.

Hugh
