Im still thinking about switching to Intel and obviously every single review mentions how hot this CPU can get. Thing is: This is mostly at STOCK SETTINGS and in BENCHMARKS. How about real world usage? Can anyone share his experience with this CPU and with reasonable powerlimits/undervolting? Im also planning to use my aircooler, a Noctua u12A. My goal is to keep the PC quiet, would this be possible with aircooling and a bit of fiddling in BIOS? Im cool as long as I could keep the RPM under 1000 much like I do right now on my Ryzen CPU.

Indeed.
Can anyone share his experience with this CPU and with reasonable powerlimits/undervolting?
I do not own a core i7 14700, and the only review of powerlimit less than 3 years old that i know is Techpowerup, Intel Core i9-14900K Raptor Lake Tested at Power Limits Down to 35 W, 2023-10-27, https://www.techpowerup.com/review/intel-core-i9-14900k-raptor-lake-tested-at-power-limits-down-to-35-w/
My goal is to keep the PC quiet, would this be possible with aircooling and a bit of fiddling in BIOS?
It is totally possible but it will cost i-do-know-how-much perf.
The u12a isn’t a top tier cooler but it’s also true that if you mostly game the CPU will see relatively low usage. And with undervolting you can gain a lot in efficiency without sacrificing too much performance. All core workloads could suffer a bit more though.
If you think it’s the right CPU for you I’d say go for it and don’t worry too much.
its an intel cpu, so its the best cpu money can buy. it performs extremely well under load and at idle. ryzen both consume more at idle and are harder to cool for x3d chips thanks to an added cache layer between the die and heatsink.
my nhd15 is whisper quiet, during games i limit the fans to 60％, this lets m do 5600mhz all cores with a pl1/2 or 220 watts all while being quiet. my old 5800x3d was giving more hadaches and that was the best.amd cpu in 20years.
intel has no competition and nver had since athlon. id legit want an i5 over an 7950x3d or anything amd.
did intel pay you to write this comment
what？ no i just fell for team red marketing and bought a 5800x3d . please be my guest and go get a ryzen. the more you ll use ryzen, the more youll find out. and when you become like me just sell the ryzen back to some other sucker so he too can find out.
Just set power limits according to the workloads you run. Unless you’re blasting all cores at full tilt, Intel isn’t any hotter than Ryzen.
This article might be of help in making a decision.
Throttling your own cpu seems to be a bad idea bc then you do not get what the benchmarking boast and in the end perform worse than an amd product at similar price?
In 99% of use cases you get exactly what benchmarks promise. Power limits only affect very small set of workloads.
I keep my 12900k cool with a Peerless Assassin. They’re <$40. Under full continuous load I would not expect most setups to be silent though.
I have a 13600kf, dual tower thermalright peerless assassin was still noisy even with undervolting and custome fan curves. I can only imagine what next gen i7 sounds like… I ended up getting an aio by the time all was said and done.
(I mostly game with it but occasionally work on audio stuff)
Just for comparison: I have the 13700 (non-K) with b760 motherboard and if you stick to intel 65w tdp, it’s cold. But when you turn on the performance mode maxed to 90c, it goes up to 93c 5ghz-5.2ghz all p cores. Everything “cooled” by 240mm aio and with a contact frame. I bet it will reach the 100c if I disable the temp limit completely. The max power I get is 215-260w. And yes, I use it for work everyday and it reaches that temp. But intel made the processor to run that hot so no biggie.
Intel cpus are incredibly easy to cool, but at the same time it left without any power limit they will literally draw up to 400 watts in multithreaded workloads. I’m running a U12A on a 14900k and it works like a charm, but again, it depends on what your goal is. By maxing the fans and letting the cpu get to 100c I get around 43k in cbr23. That’s both loud and hot. But on the other hand, dropping to a score of 40k will bring the temps down to 80c and the fans are just chilling.
It strongly depends on your real world cases. Gaming workload? Temperatures are fine. Rendering workload? A lot higher temperatures, and it depends on your cooler whether that’s fine.
I’m willing to try some scenarions you’d wish to know about at 1000rpm fan speed and report the temperature and performance results (eg how long did it take to encode some audio or video etc) as long as I don’t have to pay for the software in question (like games) though😅

It depends what you’re after. That’s a smaller heatsink with only a 120mm fan, so if you’re looking at maxing out all the cores rendering, that fan is going to need some serious RPMs to get enough air through the find. If you’re talking moderate load on some cores, you can probably keep noise quite low by setting an appropriate fan curve. At idle you can probably set the fan to turn off and go passive.
I have a 13700k with a 240 AIO and temps are fine and manageable in games. They are only hard to tame on all core loads.
13600kf with Artic Freezer II OC 5.6 ghz all cores and e cores stock on gaming usage normally it’s between high 40s lower 50s
Temp vs power, knowing the temp without the power number is rather meaningless. Also no one knows about your “real life use”, someone runs them for product, some uses them for gaming. You can definitely undervolt, but in all core work load, your CPU will still try to run against PL to sustain indicated boost number. Unless you hit a major silicon lottery and let’s say you can run 5.6ghz at 1.23V, the power draw in all core bench will still be high. You will save a lot of energy in lighter loads tho, thus better temp.
Most cooler/waterblock has a limit between 250W-300W without deliding the CPU(low 20 ambient, case config varies). The hard limit/bottleneck occurs at the IHS. For example I have a 13700K with Optimus Signature block with 2x 280mm rad (tho in a small hot case), I cannot run at 300W without throttling.
Also note most people reporting typically cite a software-displayed power number but in reality on-die Vcore is often much lower, a lot of times people aren’t really running anywhere remotely close to high 200W when they say their CPU is running at only 80+C all core.
Realistically with U12A and 1000rpm, your limit is somewhere around 180-200W. Source: I used to run a Thermalright U120EX (which is almost identical to U12A) with 13700k. Tune in your undervolt offset/ VF curve, then starts to play with power limit and settle at the value that you are happy with the combination of both performance and noise level.
I got my 14700k and have been testing and setting in up in my latest build. I run everything at stock, with the exception of voltage, where I set for a negative offset of 0.030. I am cooling it with a 360 AIO.
- In benchmark, C23, I get a maximum of 84C
- in various games, I am between the upper 40s and the low 50s the vast majority of the times. The max I ever saw was during Cyberpunk, when I read 61 once. I VR never went above 40 pretty much
Hope it helps!
