http://forums.guru3d.com/showthread.php?t=255960 I've been using this: Change only T slope to 7, which gave me an idle temp at around 60 celsius, at about 26% duty cycle. But after rivatuner 2.11 something seems to have changed. Because i used the calculation in that thread To find out what the duty cycle will be at a certain temp. And as i said in that thread So what can i do to get back to my "perfect" setting? Am looking at an idle temp around 60, which increase as things get hotter. Edit: And @Unwinder you said: What settings do i need to set, to be able to adjust 1% steps?
