Question 14900k will it work with the following components or go 14700k

[jay781]

hi i recently purchased a 14900k reason buying i though if im making a new pc for gaming and streaming i know 14900k is overkill for my use case reason i got it was only £70 more than the 14700k for me at time of purchase

here are the parts that i have

gigabyte z790 gaming x ax motherboard https://www.gigabyte.com/Motherboard/Z790-GAMING-X-AX-rev-1x#kf

Corsair Vengeance 32GB DDR5 6000MHz CL36 memory

i have a 3080 rtx

i psu is a rm850x 850w corsair

case is a corsair 3000d

Kingston 960gb sata ssd

i havent choose a cpu cooler yet

iv been told the 14900k runs very hot in temp i was thinking of getting the 14700k instead so sell my 14900k would this be a better choice as it will run cooler than the 14900k

also if i decide to to keep the 14900k if i get a good cooler for it to run cool would i be able to install cooler without under volting etc so straight install cooler with out changing settings in bios?.

The 14900k runs super hot when running cpu testing programs like Cinebench, Prime95 etc, but with a good cooler you should be fine running games and streaming. You could also dial in a little lower voltage without losing any performance, to ease the temps a bit. In Bios settings you can use Ai bios cooling setting to let the motherboard dial in the cpu with your cooler. Using settings like use without limits gains little to no performance increase and causes unnecessary voltage and temp increase.

It all depends on what you set the p1/p2 power levels at. Check the motherboard setting some are setting this at the overclock values out of the box.

Without looking it up I forget exactly what values intel recommends. If you set it to those values with a even half way decent cooler you will never come close to thermal limits.
If you set either the 14700k or the 14900k to 4095watts it will run unlimited and likely hit the thermal limit even with the largest coolers.

It depends on how much hassle it is worth to get the other cpu. They both kinda have the same issues when it comes to power usage and cooling, the 14900k just a bit more.

So if you were to get a large 360 aio you can likely set the power to about 300watts on both p1/p2 and it will keep it a few degrees under the thermal limit. The arctic liquid freezer 2 360 works well if you want a cheaper cooler.

Also what you will find is the these cpu only hit those thermal number when you are running all core applications. Everyone tests with cinebench. If you can adjust the powerlimit so it does not thermal throttle in cinebench you will not have issues in normal usage. For things like games only 1 or 2 cores will clock up and all the rest of the cores will sit fairly idle you will be nowhere near the limits.

Playing with the p1/p2 levels is a very basic overclock that is simple to do and really not that risky. Intel claims it is no problem to let the cpu just limit itself thermally with p1/p2 set to unlimited. I still tune mine to just barely under the thermal limit.
