Can the built in fan be replaced?

Technically yes, but we do not recommend it because the built-in fan does not use standard fan connector that you see in retail PC case fans. Please also keep in mind that malfunction occurring after fan replacement may also void warranty.

Do i need a sas controller with this to use my sas hdds on my gaming pc (aorus z590 ultra motherboard)?

The FS305-12G connectors are just pass-throughs so if your SAS HDDs require SAS controller to operate then they will behave the same when used in the FS305-12G. So the answer to your question is yes, you will need SAS controller to use SAS hard drive in the FS305-12G.

What is the max drive thickness im wanting to use 5 seagate 20tb ironwolf pros?

The Seagate 20TB Ironwolf Pros are standard sized 3.5" drives with thickness of 26.1mm, which is what the FS305-12G was designed for. They should fit without issues.

How is this supposed to connect sas drives if the outputs on the back are all sata?

Both SATA and SAS share the same infrastructure the port will support sas if you mini-SAS however you will need an adapter cable as it’s infrastructure is quite different. Either way you need a SAS controller as well.
