NEW Server Build Question

[JohnWT]

I'm looking at server build to utilize TrueNAS as a storage solution. I had a few questions in regards to this build:

AMD Ryzen™ 9 7950X 16-Core, 32-Thread Unlocked Desktop Processor
Noctua NH-D15 chromax.black, Dual-Tower CPU cooler (140mm, Black)
AsRock Rack B650D4U-2L2T/BCM
4 x Micron - DDR5 - module - 32 GB - DIMM 288-pin - 4800 MHz / PC5-38400 - unbu
7 x Fractal Design FD-A-TRAY-001 HDD Drive Tray Kit - Type-B
Noctua NT-H1 10g, Thermal Computer Paste (10g)
Fractal Design Define 7 XL Black Brushed Aluminum / Steel E-ATX Silent Modular Full Tower Computer Case
2 x SABRENT 1TB Rocket Nvme PCIe 4.0 M.2 2280 - mirrored boot drives
16 x Seagate IronWolf Pro 20TB NAS Hard Drive 7200 RPM 256MB Cache CMR SATA 6.0Gb/s 3.5" Internal HDD ST20000NE000
CORSAIR SF750 CP-9020186-NA 750 W SFX 80 PLUS PLATINUM Certified Full Modular Power Supply
2 x LSI Logic SAS 9207-8i Storage Controller LSI00301
CableCreation [Reversed Cable Mini SAS 36Pin (SFF-8087) Male to 4 SATA 7Pin Female Cable, Mini SAS (Target) to 4 SATA (Host) Cable, 0.5M, 1.6 Feet

I understand the processor is a bit overpowered, but based on the price and what I would like out of motherboard, this is what I settled on.

My questions are:

1.) Is the cooling sufficient for data storage?
2.) Are there any parts suggestions/substitutions?
3.) What is the best way to power additional sata drives? I have enough built-in power for 12 but would require 16 in this build. What's the best/most reliable way to power these (i.e. what connector/cables)?

I'm happy to answer any further questions. Any help would be greatly appreciated.

Thanks in advance!

Boot drives generally need to be 16GBs, though I would recommend 32GBs as a minimum today. Some people get away with 8GBs. TrueNAS does not allow sharing boot drives for other uses, except swap space. (Thus, some people use larger boot devices, like 32GB or 64GB, so that swap space can be exclusive to the boot device and not scattered over data devices.)

Using 1TB NVMe for boot devices is not only over-kill, it is money you can use elsewhere.
Simple SATA SSDs are more than enough for boot device.

I don't have any comments on the rest of the build, except that using cutting edge CPU, (AMD Ryzen 7000 series), and memory, (DDR5), can cause weird issues / problems. Like CPU temperature reporting to fail.
