I just bought a R620 server off of ebay. When I turn it on, the fans go up to 100%. It seems fans speeds are tied to iDRAC, and I'm not able to tolerate 100% fan usage due to noise constraints. However iDRAC doesn't seem to be installed on my system. I read online that installing the iDRAC firmware is free, it's the license that cost money, so I'm looking to try and install iDRAC so I can configure fan speeds.
Currently, when I boot the server, I get this
Configuring Memory... Done
Initializing iDRAC... iDRAC not responding. Rebooting
<reboots>
Configuring Memory... Done
Initializing iDrac... <not sure what it says here>

During post, there is an iDRAC initialization error, but it allows me to continue. Once it posts, I can open up the bios. When I go to the iDRAC settings menu in the bios, it says iDRAC is not installed.
I did try Platform Specific Bootable ISO, which successfully boots and installs some drivers, but does not mention iDRAC as far as I could tell. This did not change anything related to iDRAC.
In the event of XY problem: I don't care about iDRAC whatsoever, my goal is control over fan speeds.
Here's some pictures of the process:
