This exact fan failed on my Seasonic Focus GX-700 after 2 years. It started making rattling noises, the shaft inside the hub rounded itself out of the bearing. Replacing it was a pain in the ass because the fan controller is calibrated for a specific amp fan, and if you use one thats rated over or under the stock fan, it will either spin faster or not spin at all, the later of which was my issue because I upgraded the fan to a beefier ball bearing NMB.
Seasonic should get a clue and use ball bearing fans in PSU's they market as premium and charge top dollar for. A quick google search will reveal I am far from the only one with a Seasonic PSU fan failure, and while its under warranty, you will be without a PSU for 2 weeks during the RMA process as they do not offer advanced RMA, and the process itself is a frustrating social experiment I lost patience with and opted not to go through.
I would just replace the fail fan with a case fan and connecti it to the motherboard. The silent/fan-stop feature is unnecessary because one more running fan would not make a different.
If you don't have a fan connected to the PSU, the fan controller prevents the PSU from powering on because it thinks the fan is dead. You could put a resistor in to trick it, but then you are faced with a fan that is running independently of the PSU, disregarding its temperature zone. Sure, you could put a fan in that runs at full speed, it would be noisier than necessary. Or you could roll the dice and try running the fan based on case or CPU temperature which would theoretically scale with PSU load, but...all Seasonic needed to do to avoid ALL OF THIS BS is to put a reliable fan in their PSU's.
I have a 15 year old PC Power & Cooling Silencer 750 that has way beyond 100,000 hours on it. Original fan, still silent.
Why do they still make those huge PSUs with those silly huge and ancient atx power plugs? I mean all it does is converting to 12V power… the rest is just useless 5v/3v stuff for long obsolete tech like 2.5” hdds…
Also, who the hell still needs 10 sata, 3 molex & 1 floppy power plugs. Those things are ancient (well 3.5” hdds are still a thing but, still motherboards with more than 4 sata ports are getting rare…
3.3v is still used by m,2 drives on your motherboard, and it's also present in pci-e slots (up to 10 watts, and in theory used in sleep/stand-by mode by video cards). 3.3v or 5v is also often used by motherboards to produce the voltage required by RAM to work using a dc-dc converter (3.3v or 5v down to 1v...1.65v). 5v is still used by USB ports, chipsets, some onboard devices.
A motherboard manufacturer could produce 5v and 3.3v on the motherboard using dedicated dc-dc converter circuits like the ones for CPU and RAM, but would increase the cost of the motherboard. They would also have to include a ATX 24 pin to ATX 12V0 only adapter cable and risk people not buying the motherboard because they don't like the adapter cable or because they avoid the motherboard simply because they don't see the big 24 pin connector in the picture of the board and don't bother to read the description.
Wait, do you really think your CPU, RAM and other chips run on 12 volts? Because they don't. All of those voltages are absolutely necessary, they are not obsolete at all.
CPU and RAM don't use any of the supplied voltages directly. They are both converted down to around 1 to 2 volts in the motherboard. The CPU has a dedicate 12 volt plug for just this - Originally introduced for the Pentium4 in year 2000.
Shouldn't there already be an industry wide recall of the 12VHPWR plugs? They are all ticking time bombs for wrecking graphics cards and even a fire hazard.
The Thermaltake unit is not yet available for sale. They did technically say this month, but as today's the last day of the month, I don't expect they'll make it.
It's going to take some time to start including the new cables. Large PSU inventories make for quite a buffer.
I bought the MSI MPG Ai1000P from MicroCenter and it has the 12V-2x6 plug. Says so on the box and printed next to the plug on the unit it's self. The cable also has a yellow tip to indicate it's the 12V-2x6, came with a info slip of paper saying so. But MSI's website says it has the old connector. It's like a quiet revision.
Been using Seasonic for years, have a 450W (don't remember the model) in my 10y old 4770, it's still working, used a TX-750 Platinum on my 1900x, using a TX-850 Titanium on this PC. Not 1 has failed.
I still have an ultra-cheap Xigmatek PSU from many many years ago that came with a 135mm FDB fan. The PSU still works, too. Why we're still getting 120mm fans in PSUs is beyond me.

This is another high quality PSU from Seasonic. They are the gold standard in PC PSUs IMNHO.HaninAT - Wednesday, November 29, 2023 - link
My only issue is that I just bought their prior generation Focus GX 850... Oh well... I will need the new fangled PCI-EX power lead eventually anyway.Samus - Wednesday, November 29, 2023 - link

15 years equals ~129600 hours. You ran over 100.000 hours during this time? 11 and a half years of non-stop running? I find it hard to believe.bernstein - Wednesday, November 29, 2023 - link

Dude, that's why it's modular. And can even cut off what you don't want.meacupla - Friday, December 1, 2023 - link
I'd hate it if I bought a PSU for a media server and it didn't come with at least 8 SATA power connectors.mariush - Monday, December 4, 2023 - link

I don't see any mention of whether the 12VHPWR plug has been updated to a 12V-2x6 plug. The implication is it's still using the old flawed plug.Ryan Smith - Thursday, November 30, 2023 - link
There aren't any PSUs currently available with 12V-2x6. That'll be a 2024 thing.evanh - Thursday, November 30, 2023 - link

Given the existing 12VHPWR cables should all be on an immediate recall, I can't see inventory being any excuse at all.RomanPixel - Friday, December 1, 2023 - link
