fixed: Alienware M17x R4 - AIDA64 caused fan stop in Bug reports Posted December 5, 2012 · Report reply Thanky your Fiery for the fast response. I could not resist and reinstalled AIDA64 and disabled Dell SMI sensor support. And that does the trick and solved the issue. Now its working as expected. The side effect of disabling Dell SMI sensor support is that the CPU Fan speed is not any longer shown in the OSD. If possible, please take this finding into account for your release planing and disable this feature (by default). Nevertheless I'll do the same tests as soon as I get my M17xR14 replacement and report back here. Additional I report this solution back to DELL at a later time, in case someone else will report a similar issue in the future. This will improve their Tech Support and may save some money on their site.
