Title: 5870 fan auto increasing speed in short bursts at 90c~ Post by: mysticode on January 25, 2014, 07:15:17 AM At around the 90c~ mark, the fan on my 5870 will do quick bursts to get to around 50% speed. Before then, it was running at around 40%. Regardless of percentage, it does this, will do quick bursts raising the speed up another 10% for half a sec increments, over and over, until temps go below 90c again.
Any idea why this might be happening? Thanks! Title: Re: 5870 fan auto increasing speed in short bursts at 90c~ Post by: mysticode on January 25, 2014, 07:38:40 PM Bump, this is happening at 50c as well. Pretty much it thinks it needs more fan, but only does it in bursts. So weird.

However I am really perplexed to why this fan is going nuts like it is. |
