Quite system

Dynamisch · April 3, 2023

Hello everyone. I’m new here. I’m about to order hardware to build my first pc. I’m going to use the pc for cad/cam software and cnc controlling software. The pc has to be quiet near silence while sketching in Inventor and Fusion, with enough power for complex simulations. Going with intel’s 13th gen (i7) or amd 7000 serie (7900) for an silent system? My thoughts in this process is less heat=less noise.

I’ve done research online, but im just missing practical experience. The amd X processors have an target temperature of 95 degrees, regardless if it can gain any performance. I can assume that such algorithm will make the pc very loud. But on what kind of workload these processors try to go to 95C? I read that people set te max power limit in the bios to its maximum advised ppt of 200W for the 7900X, so it can be cooled better (and less noise I guess?).

Im just not get this algorithm from amd. I mean, also the 13th gen processors run hot, or even hotter under heavy workload. Lets say that the i7 is also power limited to its advertised ppt at 253W in the bios. The 7900X 200W should run cooler than the i7 on 253W in theory (Under full load).

Being quiet under full load is not my goal. For simulation it’s oke to make noise. For an normal workflow i want it to be quiet, like assembly’s in Fusion and Inventor from 10/50 parts, browsing on the internet while doing work, sending emails ect. Should i go for team red or blue?

this isn't their target temperature, this is their max. Intel's max is 100 degrees celsius. If you want to go amd, check out the ryzen 9 7900 non x. Much better thermals compared to both the 13700k and 7900x while only losing a fraction of the performance with 12 high performance cores. Just look at its temps in prime95 on an nhd 15

For your use case go with the 7900 non x since you would need those cores. The best offering from intel (13900k) only has 10 p cores (or only 8). Also the 7900 non x can be overclocked to handle these workloads nearly as good as the 7900x.

team red, 7900 non x with 32 gigs of 5600mhz ram on a b650 board

Noise is related to heat. the hotter the environment the harder any cooling solution being used has to work.

Easy step solutions are a case with good airflow so that heat can be removed efficiently and not build up inside the case.

Fans that operate well and can move air at a reasonably low speed reduces noise.

Tuning a fans curve so that they kick in at higher speeds only when needed.

On a personal note intel cpu's I would lean towards water cooling using an AIO and for AMD I would be fine with using Air and any decent quality tower cooler.

Also buy a PC case that has function over fashion....there are tons of very good cases on the market in all price categories.

Personal choice right now is the Fractal Torrent.

Thanks for the reply. 7900 non x was what i had in mind to. Very nice review on YouTube btw. For some reason i thought that i need that 10/15% extra performance, what is unnecessarily in my situation. The non x is probably my way to go.

Thanks for reply. I’ve ordered an fractal design north with an glass side panel instead of the mesh. It got nice aesthetics and should have good airflow to. I want to place 3 Noctua NF-A12x25 PWM case fans in the front, 1 in the back and 1 or 2 at the top.
