Solved!
Go to SolutionProblem using iDRAC 7.20.10.05
Server Dell PowerEdge T360 with DELL PERC H755
iDRAC , BIOS and PERC latest versions
After updating iDRAC to the latest version available on the product page (Dell website) i.e. iDRAC 7.20.10.05 the rear fan (page 18, position 4 in poweredge-t360-technical-guide.pdf) periodically starts at maximum speed for a short period of time (up to a few minutes).
It is annoying and can be a cause for concern!
Rolling back to the previous version iDRAC 7.10.90.00, A00 (Maintenance -> System Update -> RollBack) seems to solve the problem.
Could it be a sensor set incorrectly in the new version that is causing the problem?
After reverting to the previous version of iDRAC the problem disappeared within a few hours today.
I'll check again tomorrow but it's a bit strange that the hardware problem would appear right after updating iDRAC.After almost 24 hours of reverting to the previous version of iDRAC the problem has not appeared again so from my point of view the problem is with iDRAC version 7.20.10.05.
In none of the versions, in IDRAC -> System -> Inventory -> Hardware Inventory -> Fan 1 -> did problems appear.Fan 1 ActiveCooling1BaseUnitsRPMCurrentReading1320 RPMDeviceDescriptionFan 1DeviceTypeFanFanTypeStandardFQDDFan.Embedded.1InstanceIDFan.Embedded.1LastSystemInventoryTime2025-02-10T07:52:21LastUpdateTime2025-02-11T07:25:28PrimaryStatusOKPWM15 %RateUnitsNoneRedundancyStatusNot ApplicableUnitModifier0VariableSpeed1Do I need to buy another fan?
Or can Dell send me a fan?
Already 2 users have confirmed that the problem is with the new version of iDRAC!It's not the end of the world that a version of iDRAC doesn't work properly and destroys our fans (does DELL replace them?) the problem is that the version is still on the site without even a warning about the problem!
A warning or even removal from the site would stop other administrators from going through this problem that can be solved with a revert.
We can stay with the previous version without making any more firmware updates until the problem is solved.
The previous version has a problem with firmware updates and the current one with fans, what do we choose?The architecture designed by Dell for servers is OK, as is the iDRAC, it's a shame that such situations occur.
