Build’s Name: NAS 5.0 (I think? My First NAS was an eeePC 904HD with two USB HDD's, so that might indicate my level of age and jank that I've been used to)
Operating System/ Storage Platform: TrueNAS Community
CPU: AMD Ryzen 7900
Motherboard: ASRock B650D4U-2L2T/BCM
Chassis: Supermicro CSE-847
Drives: TBD
RAM: TBD
Add-in Cards: LSI 9300-8i
Power Supply: Supermicro 1280W SQ
Other Bits:

NOTE: Australian location and pricing.

My Synology DS3617xs + DX1215 is getting a bit full with all drives used (12 x 6TB, 12 x 10TB). I also didn't have a backup solution, so trying to tackle two birds with one stone - move my primary NAS to a CSE-847 (and I have a spare if I want parts/a JBOD) and then use the Synology for backups at a friends house (putting a rack mount is slightly more obtuse than a tiny box).

The CSE-847 was a steal in AU btw, 400$ each and I got two. Comes with an X10DRI-T4+ and all the gubbins if anyone wants.

Question for the group, whats the go to fan solution for the CSE-847 these days? I'm currently envisioning a front panel fan mount (I have a 3D printer) using some form of USB control rather than trying to feed fans inside, and then a 120mm x 3 fan mount for the middle. Fans that I've seen mentioned to fit include Delta, Arctic and Noctua IPPC, keen to understand what is the 2025 solution (noting I've not seen builds lately - is this also a terrible idea?)

If you aren't running a higher-wattage CPU and lots of HBAs, you can always just run the stock fans but fewer of them.

I'll just say this (and I have a few 847s as well).

Everybody who recommends quieter fans without understanding the tradeoffs is...well...

Cooling 36 3.5" HDDs packed tightly together is no joke. If you'e planning to actually utilize all 36 drive slots, plan accordingly, in terms of cooling. We haven't even gotten to the CPU/Motherboard/Add in cards etc.

The stock fans are loud, really loud at anything above idle, and they will go above idle if your system gets use. If it's just a trophy...well... :) But, the stock fans are high static pressure, high speed, watt eating monsters and they do their job.

In my case, I replaced the stock fans/fanwall, with something different that can hold 120mm fans.



Those are five 120x38mm Delta 1212SHE fans now, and these fans have even higher static pressure than the stock Supermicro/Nidec fans. And they're much much quieter. Not exactly silent when the chassis goes full blast, but I'd say at full blast they're ~1/4-1/3 the noise of the stock fans. And they provide better cooling than the stock fans.

TL;DR - Choose wisely. :)

Thanks @kapone - Understand the issues with the fans thus why I'm putting a lot of thought into it and asking advice :). Did you have to crimp the delta fans yourself? Can't remember if it was the Deltas I saw a thread about having to add connectors yourself.

Nah, these were standard 4 pin PWM fans.
