Can the Thermalright Phantom Spirit 120 SE cool the Ryzen 9 7900X (non 3D)?

[-X-]

Is the Phantom Spirit 120 SE capable of cooling the 7900X under multi core workload? Some tests conclude that most air coolers can't keep the 7900X under 95C while others recommend coolers like the Dark Rock 4 Pro and AK620 and the PS120SE seems to be close to them in cooling performance overall.

Yes, easily.

My stock 7900x hit about 92-93c but running these chips without touching Curve Optimizer for a quick and dirty -20 undervolt is dead simple. You have to understand that 95c is the target temperature and seeing that temp doesn't mean something is wrong like it did years ago. I cooled mine with an AK620 then Assassin IV before I sold it, even broke 30K in Cinebench R23 entirely air cooled AND a an 85c hard temp limit in the BIOS. The PA and PS120's are as good if not better in most tests. 

 

Super simple to cool by air, even easier if you undervolt. 

 

Back when it had an AK620.

So even without an undervolt or temp limit it should be fine? First idea was to upgrade to 5900X as a cheaper upgrade on AM4 so the PS120SE was a choice for that one, but found an ok price for 7900X + TUF B650 so weighing in the options.

 

Of course if I can get it stable and maybe a limit to 85-90C that'd be great, I assume how far you can undervolt differs from cpu to cpu?

Define "fine"? Even at 95c these chips are "fine" and designed to run there in multicore loads.

Yes, though an easy -20 all core generally pretty easy for most.

About 95C where it won't fry itself  especially during summer

Just watched a vid from Tech Yes City undervolting a 7950X, but he used Ryzen Master instead of going into bios, does it make any difference or any pros and cons for doing it through the app?

You won't be able to get the temperature too much below 95 because it is literally designed to achieve 95. I think it was Jayz2Cents that demonstrated that in a video. 

 

The good news is that the more cooling you use, the more performance you'll get out of it. Performance-improving measures are how it ramps up the temp to 95.

Use the BIOS, it’s dead simple and you’re not relying on software to apply it.
