Review: Well built, works perfectly, Trayless design works well! - Bought 2 of these for a Silverstone 4U Rackmount case. It installed very easily, and the build quality seems solid. It's nice to be able to open a bay, pop a drive in and close the bay without having the mount the drive in a tray. The only downside really is the price. For that cost of 1 of these I could have bought 2 Rosewill or other cheap brand. But these certainty seem to be worth the extra money.
Review: Good solid enclosure, but swap the fan if you can - Overall, this is a solid enclosure but it leaves a few improvements desired. The front drive doors are OK, so I'm not sure what other reviews are complaining about. Are you slamming the drives into the enclosure? I hope not, because this is plastic and you should take care in inserting your drives to meet the SATA connectors in the back. Just take your time and pay attention. Now, the fan is garbage. G A R B A G E. I pulled it from the enclosure and swapped it for an Arctic PWM fan which now is controlled by my board based on the HDD temps. Low HDD temps? Low fan speed and low noise. However, getting a slightly larger fan to fit may require a dremel and/or drill bit to enlarge the screw holes on your fan shroud, but after you get the screws to fit, all is well. Dont worry about damaging your fan since the fan case will fit back over whichever fan you reinstall, for a nicer OEM look. My fan barely hums along when all is well. Air flow is adequate enough for when your drives get hot and I can feel the hot air flow when the fan is running at 2400 rpm. I push air inside out to balance my overall case flow but YMMV.

## Questions & Answers

**Q: Can the built in fan be replaced?**
A: 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.

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

**Q: What is the max drive thickness im wanting to use 5 seagate 20tb ironwolf pros?**
A: 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.

**Q: How is this supposed to connect sas drives if the outputs on the back are all sata?**
A: 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.

### ⭐⭐⭐ It’s pricey for what you get. Not the best quality Silverstone.
*by G***Y on March 23, 2021*

Looks good, quality isn’t as good as I’ve come to expect from Silverstone. It’s pricey for what you get but I’m adding more drives to an silverstone rm41-h08 which already has an FS 305 built in so I guess I’ll just have to be careful with them while installing /swapping drives.
