Re: [Cooling] Looking for a fan that notifies of failure
I can't think of a way to do this, (sense a fourth fan).
However another option might be to set the fans to not be variably temperature controlled. I have found sometimes those kind of sensing programs aren't that great and can lead to overheating. There should be an option to make all three fans run at full tilt constantly. |

Ever hear some of these IBM servers when you first power them on? You'd think you were working on the tarmac at the airport if they left them on that speed constantly. A toddler might get a heck of ride around the computer room on the server if they blew just a bit harder. 
The fan we added to blow on the cards is, of course, not variable speed currently. It does the job, but if it fails and we don't know it...

1 edit | Alright, I didn't realize you had the server in a place where noise is an issue.
The two tach signals into one controller won't work. I'm not sure what it'd do to report the speed of the fan, but regardless of what that does, if one of the fan fails, it'll just report the speed of the other one. |

| No problem. Not that I really care if they are blowing full speed 100% of the time. But for some reason this particular server just doesn't seem to be tumbling enough air over the PCI boards with its own factory fans. Not sure if running them at 100% would change that or not.
I don't have personal access to the server as it is currently in some labs in another state. I have only been able to talk to colleagues and pull the IBM manuals.
