Looks pretty good. I would advise skipping HDD entirely for a gaming build. You can get a similarly priced M.2 SSD which will perform significantly better, be easier to install, less prone to failure (at least mechanically) and be tidier cable management wise. I haven't used an HDD in a long while, but I have no reason to anymore. For a workstation, you should still aim to use an SSD as your "OS" drive, but HDDs make more sense when dealing with large amounts of data.
Fan wise -- anything from arctic should be sufficient. Look up build guides for your case to see what size you need, and then decide if you want RGB or not.
The 5090 could be released in 6 months, forget about the 40 series.
Add at least an NVMe for installing Windows and software programs. Do not use mechanical hard drive for Windows.
The B series board might not be good enough for the Ryzen 10,000 series, but 7800x3D is good, but playing at 1440p it's going to use more GPU than CPU, but 7800x3D is still exellent.
Any reason why you're going for a hard drive in 2024? El cheapo NVMe SSDs aren't that much more and are lightyears faster, and will probably be more reliable. Yesterday I picked up a 2tb Sk Hynix P41 for $130 which is absurdly cheap for such a good drive.
I added a hdd because I like having some slow storage for mass storage, but you're right that I won't need it, as I'll probably take my 4tb nvme from my current PC and transplant into the new one as the only storage.
That'll still leave me with a small nvme for OS and software and a spinning disk for mass storage on the workstation.
For the cooler, you can get nearly equal cooling from a ThermalRight Peerless Assassin or Phantom Spirit (Evo) and save like $130. You could also get a good AIO like the Arctic Liquid Freezer III for less if you're okay with water cooling. Even the newer D15 G2 is cheaper if you're okay with it in classic Noctua colors instead of all black.
I don't know that you'll need any extra fans with the Torrent case, but for best value go with Arctic P12/P14. I think the Phanteks D30 will get you a bit better cooling and acoustic performance, but at a premium. HardwareCanucks and other youtube channels should have a good run down on your options there.
My reasoning for cooler I picked was partly because of Noctua's reputation for reliability and good noise levels.
I am open to other options, but I'll be sitting pretty close to the pc and can be sensitive to noise.
I've tried to look up information about the coolers you've mentioned, but I'm struggling to get a good feel for them.
I do not care and colour, but I prefer avoiding RGB if I can.
I think you're right. I somehow missed that the torrent came with it's own large set of fans.
