Dell Poweredge T610 Fan RPM/Sensor Errors

Hi,

I have a Dell Poweredge T610 that I bought a few years ago. I haven't used used it in a while but I decided to try get it up and running again. However, every time I power the server on, it boots just fine and the fans settle down and go pretty quiet, then randomly the fans will ramp up to 100% and 2 errors will appear on the front screen to do with a fan sensor and fan RPM. But then 20 seconds later, the errors will disappear and the fans will settle back down. Then it happens over and over again every 45 seconds or so.

I've given the inside of the server a good clean out using air duster, focusing on the connectors for the fans to make sure there's no dust in them. But nothing seems to be fixing it. It's running BIOS version 6.6.0 and there doesn't seem to be any other updates to do I don't think.

I ran an "Express Test" in the hardware diagnoses section of the system utilities menu and got these errors:

Test Results : Fail
Device : IPMI
Test : IPMI_System_Event_Log_Check
Error Code 2900:0221

Any assistance as to what I can do to fix this issue would be greatly appreciated.

Thank you.
