What is your other hardware? Is anything overclocked?

PC OFF before all of this of course Make sure your RAM is in the correct slots, you could also try just booting with one stick of RAM just to narrow the problem list down a little. I'd maybe even try to remove the GPU and then see if your CPU fan kicks on. Also a simple way of narrowing down your troubleshooting, even though you won't have a display output, that's not really the point of the experiment. EDIT: Is your PSU plugged in with whatever it needs? (Both plugged in on the motherboard and with a PSU cable if available)

Does your display turn on and just not display anything or does your display not respond at all? You mentioned this being a new build, does that mean there is an old building around or is this your first build?

Do any other fans turn on when you boot besides the PSU fan? GPU, CPU?

It's a spooky graphics card for halloween

If you wanted to be extra safe anti-static wise, you could snag a cheap anti-static wristband as far as your GPU goes. You're probably fine without it though.

Not sure on the brand, but be careful with getting too large of a display(say like a 27") with a 1080p monitor. Sometimes it can be a little iffy with not having great visuals and it can look blown-out

Are all of your graphic's drivers up to date? whether that be integrated or discrete? Could also be that your pc needs to be updated in general, if you didn't connect your pc to a network while installing windows, it could have a whole mess of updates to install

Does the PC turn on and stay on(internal LEDs, etc.)? Just go to a black screen when the PC is on(assuming it gets this far)? Or is this a case of it turning on momentarily to just flash some lights and then nothing? Not "starting" can have a lot of different meaning. Describe the "nothing" that happens.

I would say it'll only ever truly be bad if it starts shutting itself off. But for now, you'll probably just experience a bunch of thermal throttling. Agreed. Sadly.

Couldn't hurt to give your pc a good air dusting and then just vacuum everything afterwards(PLEASE DO NOT VACUUM YOUR PC). Chances are, just some general cleaning wouldn't maybe get rid of them but would greatly depreciate how many there are around.

If you are comfortable in the BIOS, usually if you have any fans properly connected(yes, even the AIO pump connector) will usually show activity and the speed of the fans at the current time viewing it. If you check that display and see that your AIO pump has no input, it is either not installed properly or isn't working.

An ergo mouse and a custom keyboard do wonders for productivity(Assuming you aren't able to change things like the chair or desk you are sitting on/at. Having a setup that you feel comfortable in is a must, especially if you plan on sitting there for extended periods of time.

Also gotta remember windows 11 is bad, just plain bad. I'm running an i7 12700k with 32GB of ddr5 @ 5600MHz and I have yet to experience any issue with windows 10 pro.

Make sure your front io connectors are in the correct place(like the power button and restart button) Its a simple problem but also a simple possible solution.

Are you sure you're following all of the steps properly? Sounds like a/multiple bad boot drive(s)

It's an interesting thought. I think it will fall into the category of the users who just want raw performance. There are already users who want a 1200watt power supply just because. Or to have a 3080ti just to play league of legends or CS:GO, regardless of the actual use(GPU cores, VRAM, etc.) or the betterment of performance(Playing with a lower end card that does the same thing). Then again, it will likely just be a phase where everything takes more power. GPU's haven't always been a high power consuming thing(with more power comes more power XD). I'm sure 10 or 20 years ago, no one would have guessed the current wattage usage and it allocations.

AMD may have slightly better options now with their new GPU releases, not sure on pricing. You should make sure to get at least a bronze rated PSU

They probably do, just make sure it is able to be ordered upfront or be willing to wait for it. NZXT requires that you contact their support, which took me over a month to actually receive the new mounting hardware for a preexisting cooler. Could be different, but never hurts to double-check That is the cooler that I am using currently for my i7-12700k, works great even playing games on ultra in 1440p(cooling wise)

The CPU cooler isn't compatible with lga 1700

The CPU cooler is too big for the case by 8mm

Is the server working for you to join with the ip you assigned/port you assigned?

Never hurts to check literally all possibilities

The 1660 isn't a tank of a card, the games could just be too intense for the GPU(try lowering your graphics settings for a more stable frame-rate)

Turbo is usually enabled by default if you have a K style CPU. When you check your BIOS, can you check the stats on your AIO pump? Basically to confirm it is actually spinning?
