I've got a HPE ML350 GEN9 Tower server which is fairly quiet during the winter. Like, my laptop and PC are louder than it. During the summer however, things are getting out of hand.
There are two areas that are problematic. These happens to be the VR P1 location at the back of the case - behind of one of the processors. Google says this would be the "Voltage regulator processor 1 zone ". The other one os the RAID controller, which is expected to be running hot.
Once the temp in the room goes over 25 degrees (C), the fans go wild just to cool down these components, causing more noise.
I am seeking advices how to cool this down, as the fans of this chassis are located at the front. I've been thinking of buying two 40mm Noctua fans and swapping them to the RAID controller passive cooler & CPU passive cooler with zip ties, but I don't think I will find a 12v slot to power it up with. Perhaps a USB (5v) fan would also do the work - I can plug it in the first USB port or power it with a regular phone charger. That way, there will be an active cooling way behind in the system, getting more air flow through that area and getting the hot air out of the case faster. Another thing I will do is relocating the PCIE network card out of that area (it happens to be right in the hot area) and placing it way down.
My main question is, what are my options for connecting the fans to the motherboard, as these server systems aren't really designed to run with anything else but what has been sold by HPE. Can I even connect another 12v or 5v component (fan) to it? If yes, how?
Here's a pic I found on Reddit, which shows the internals. The main differences is that I've got a single PCIE device (network card) and I'm running all 4 fans:

This is a homelab server, but the chassis is not easily reachable and I want to gather some opinions first before spending a few hours of just getting into the opening the box.
Any tips and recommendations are welcome, thanks.
