Hi all,

I swapped storage controllers from H730p to HBA330 in a T630 after which the fan speed ramped to 55% PWM max (around 3k RPM). 

Server has been running for around a year with H730p and same HDD combination with no issues and near silent performance. No other hardware has changed.

All firmware is up to date-

BIOS is 2.13.0, iDRAC 2.82.82.82, HBA330 16.17.01.00

Drives are 8 x Dell P/N W0VNC (TH0W0VNCSGT008BC00C8A00) with latest EA04 firmware

Thermal profile is `Minimum Power`. Changing to `Default` doesn't change fan speed. Fan Speed Offset is `Off`. Minimum Fan Speed is `Default`. 

Removing all hard drives causes fan speed to return to normal.

System has no active alerts. I've switched back to the previously working H730p but high fan speed remains. I've also unplugged all power + held power button for 20 seconds before powering on and gone through retire + repurpose wizard to clear all iDRAC and BIOS settings but issue remains.

Any advice would be appreciated!
