Reddit take

AI summary of the Reddit excerpts below — not a quote

The Thermalright Phantom Spirit 120 is widely considered the current benchmark for air cooling value, frequently recommended as a superior and more affordable alternative to premium brands like Noctua. Reddit users consistently praise its thermal performance, noting it outperforms many more expensive coolers while maintaining quiet operation. It is often cited as a slight improvement over its predecessor, the Peerless Assassin 120, offering better noise profiles and cooling efficiency for mid-to-high range CPUs.

Pros

  • Exceptional price-to-performance ratio, often outperforming air coolers twice its price.
  • Quiet operation due to large surface area, allowing fans to run at lower speeds.
  • Easy installation process reported by users.
  • Highly effective for a wide range of CPUs, including power-hungry models.
  • Compact enough to fit in many small form factor (MFFPC) cases.

Cons

  • Stock fans are occasionally criticized by enthusiasts who prefer replacing them with higher-end alternatives for marginal gains.
  • Regional pricing can vary, making it less of a 'budget' king in certain markets like Brazil.

Caveats

  • While highly effective, users with extremely high-end thermal loads (like 4K gaming builds with top-tier CPUs) occasionally question if air cooling is sufficient compared to AIOs.
  • Fan curve tuning is recommended to achieve 'inaudible' noise levels on lower power CPUs.

Best for

  • Budget-conscious builders seeking top-tier thermal performance.
  • Quiet PC enthusiasts who prefer air cooling over liquid cooling.
  • Small form factor builds where clearance allows for a 120mm tower.

Avoid if

  • You are in a region where Thermalright products are significantly marked up.
  • You strictly prefer the aesthetics or extreme overhead of a 360mm+ AIO liquid cooler.

noctua cooler is not anywhere near necessary; get a phantom spirit 120 or peerless assassin 120 for much cheaper

For the new CPU-cooler I opted to buy a Phantom Spirit 120, but I'm wondering whether it'll do me any good performance- and soundwise to get some new 140mm fans for the case.

I think the thermalright will be much more quiet. It has a lot more surface area to cool with than the Fera, so air can move at lower speed for same result.

I doubt replacing the fans on it will make much difference, at least not enough to spend money on.

would you say that phantom spirit 120 is good for this build? I intend to play in 4k so I'm worried it won't be enough

Phantom Spirit 120 with plenty of headroom.
