Title: 280x reported fan rpm issue Post by: frufru on February 04, 2014, 02:00:51 PM I've got 5 sapphire 280x's in a mining rig, running for 2 month now. The fans were set at 100 percent manually and the reported rpm was around 3700. Today I saw in sgminer that one cards rpm is stuck at 566, one is around 2800 and one at 3000. The remaining two are showing the original 3700. The temperatures are ok, between 51-62C, if I try to change the speed whith trixx the rpm changes on every card, except the one showing the fixed value, but according to the temperature it seems I can control the speed there too. I'm 2k kilometres away from the rig so can't check it myself, but I was told all the fans are running. What could be the problem? Anyone experienced something like that?
