AMD's new reference drivers are presumably not named "Crimson" because they make cards red hot, but there are lots of users reporting overheating problems using them. There are even some saying this has killed their GPUs outright, as shown in this reddit thread, which says the drivers are locking fan speeds on some systems at 20% of maximum. A tweet from AMD acknowledges the issue, saying a hotfix is coming today: "We are aware of low fan speed reports on select GPUs with Radeon Software Crimson Edition. We intend to publish a hotfix on Monday." In the meantime, this reddit post (thanks Softpedia) offers a workaround on how to perk up your fans. Thanks HARDOCP.
