indeed. But I don't think that they would consider that overvolting as such. Unless I'm mistaken. Doesn't each CPU have its own VID set, hardbaked, and that is sent to the motherboard to then provide that voltage..? We can change that, in this case as a negative offset. Perhaps with their CPU's Intel tends to edge towards the upper side of caution for all circumstances and installations. It is then down to the user, and suitable board, to make such changes to reduce them.
You do lose some performance, but it really needs to be done to get the power usage and temperatures under control. Most of these CPUs are very effective when they're power limited, even 125 watts loses very little performance in the majority of apps.

Turbo boost 2.0 & 3.0 are part of the stock features, but some motherboards apply the max turbo to all of the cores and that is an OC. I don't know if Gigabyte has this feature.
What is the most demanding task (on multiple cores) that you do and how long does it take for it to complete (typically)? You want your power limits to be high enough that you're not losing much performance, but low enough that it is easier for your cooler and doesn't make so much noise. I'd probably start with Boomstick777's suggestion and if you notice a drastic loss of performance, then increase the power limits from there.
What kind of power usage can your cooler handle before things get intolerably noisy?

Things tend to get noisy pretty quickly and often, as Ive got the cpu and exhaust fans set to hit full speed when the cpu gets to 60C.
Can these temperatures Im getting actually cause any problems with the pc? Because if not I think it might be just easier for me to put up with them. I dont think Im experienced enough to start tinkering with bios settings without a guide, and I cant find one for my bios/motherboard. Im not really up for losing any performance either, as my cinebench score isnt particularly great compared to others that Ive seen for 14700k’s.
Ive started to use headphones when gaming beacause of the added noise from the 7800 fans, so the noise while gaming isnt a big deal anymore. Like I said if its just noise thats the issue, Ill just put up with it.
Well, they're designed to run hot, so no, it shouldn't, but with these kind of CPUs I'd always set your temp and power targets for your realistic workloads.
What I mean by that, is there's usually no point optimising your PC for Cinebench if you rarely run intensive multithreaded programs. On the other hand, if your PC is running intensive tasks for hours on end (this doesn't include gaming), then you'd need to optimise it more cautiously.
For gaming, temps between 60 - 80 (maybe 85 or so, in the summer) are fine, there's no problem with that. For long-run heavily multithreaded work I'd try to stay below 90, ideally 70-80. For very short run intensive benchmarks like Cinebench, 90 odd is fine.
They are capable of being run on the limit 24/7, but it is just not necessary to have them operate like that.
Let me put it another way: allowing these CPUs to run unlimited is wasteful and unnecessarily hot. The compromise depends on exactly what you're doing, but in most cases, you can cut power usage in half, dramatically lower temperatures and noise and lose practically nothing for the vast majority of apps.
The only way to know if the performance matters to you is to actually run the things you normally use, for example: do a fixed task (like editing a video, I don't know what you use the PC for) and time how long it takes. Set PL1 & PL2 to half their stock values and then see: 1. how much power it uses and 2. how long it takes. I think you'll find that you don't lose anywhere near what you're expecting to lose.
I didnt know at the time. Its my first time owning and building a pc, so i didnt know to check for for this sort of thing. The manufacturer doesnt make it clear or advertise that you cant undervolt on these boards. I find it odd that they're made to be used with these intel cpu’s but then wont allow undervolting when its something that probably needs to be done.

This is one of the first articles to explain how the newer Intel CPUs work with the power limits / turbo modes:

I have been building PC's on and off for decades, but I would not have thought about the type of restrictions that this particular board is presenting. Adjusting vcore....... that is a kinda basic thing that I would have assumed should be there. So I would have been caught out with that one for sure.
Have you tried, if it would work, something like Intel's XTU..? perhaps it is not supported with that board, or the undervolting..? But I know that it can be done using that app, albeit I have a Z690 board and use it.

The undervolting options are greyed out unfortunately. On the bright side, I havent actually reached thermal throttling yet with xtu/cinebench stress tests or everyday use so I suppose things could be worse.
The gigabyte BIOS manual states that selecting auto for turbo power limits "sets the current limit according to the CPU specifications". This is wrong as I had it set to auto and my power draw was going way over the intel specs.
Ive now changed it to Intel POR. Running cinebench, it now doesnt draw more than 253w, 4C cooler and its added nearly a 1000 points onto my score.

Ah, just realised for mine to work I had to disable the undervolt protection in the Gigabyte BIOS. Yours does not seem to have that. Stress type tests have their place, but base your concerns of noise etc on actual use that you will be using the PC for. It might work out well for you

Its a shame about the lack of ability to undervolt but I had a play around with different power limits yesterday and Ive got it to the point where im quite happy with it. Ive set PL1 and PL2 both to 200w and adjusted the fan curves. Noise levels are acceptable now and temps are over 10C lower. It seems like there is also hardly any loss in performance.
You don't need to worry about a 14700 occasionally hitting 90. The heat tolerance of recent gen Intels is much higher than earlier cores. If it's just the max temperature getting that high, I wouldn't worry, only if you're seeing sustained heat at that level during load is it worth worrying.
Limiting the power load limits the performance of your CPU. Doesn't make sense to me to pay for the high end CPU and then throttle it down.
If you've got an AIO with its own fans, then the case fans don't provide a whole load of extra cooling for the CPU anyway as the radiator should be shifting the heat out of the case anyway assuming your case has reasonable passive airflow, so you can probably set the case fans more conservatively - or base them on one of the motherboard temperatures - in order to keep the noise down.
