Question HDDs have become much louder a week after changing case and PSU ?

[Apolepth]

Hi, recently I changed my PC case and PSU to new ones, I assembled everything and it worked fine and quiet, After a week my both new HDD and older HDD drives became significantly louder after turning on PC in the morning, they sound like fans or a vaccum or something. Since then these HDDs are the loudest thing in my PC.

I unplugged them both and it was quiet, all I heard were fans and PSU.

My specs are:

• AMD Ryzen 5 5600x
• RTX 3060 12GB OC
• Corsair 16GB (2x8GB) 3200MHz CL16 Vengeance LPX Black
• SilentiumPC Supremo FM2 Gold 650W (old one was Corsair VS550)
• ENDORFY Signum 300 ARGB (old one is some no name random case)
• Seagate Barracuda 2TB 3,5" (ST2000DM008) (the loudest from the two)
• Western Digital WD10EURX-63FH1Y0 1TB 3,5
• 2 SSD SATA and one M2 SSD

What I tried:

• Checking bad sectors, checking if the drives are bad, everything is fine, there were no errors or messages about something bad
• Changed PSU to the older one, did nothing
• Using small sound proof padding with rubber slots that slide into dedicated place in case
• Changing sata order, changing order where they sit, up or down
• Changed "Turn off hard disk after" to 1 minute and the HDD was still running
• Moving PC case somewhere open so sound doesn't bounce of furniture, HDD on the floor is as loud as in the case
• Securing them tighter in the rubber slots
• Using them upside down
• Switching SATA power cables
• Plugged in different, even older HDD but it was also loud

And honestly can't remember what's more

What I didn't try:

• Updating BIOS to newest version
• Screwing in HDDs directly to the case, not rubber slots, but they were loud when in hands, on floor, in case etc.
• Changing Motherboard, GPU, CPU, RAM, because I don't have any replacements
• Changing power outlets or power strips

Probably something more I forgot...
Sorry for any spelling mistakes or other errors, I post this to try to fix it as fast as possible, because I use my PC everyday and this sound causes real headache...

What is the cooling in the new case? Have you checked temps? Any difference between old case and new temp wise?
