Best CPU Coolers for Ryzen 9 7900X3D: Top Picks
1. Thermalright Phantom Spirit 120 EVO
Quick Highlights:
- Type: Air Cooler
- Fans: Dual 120mm
- Price – $50 – Buy Now
The Phantom Spirit 120 EVO has been making waves for its ridiculous price-to-performance ratio. It’s a dual-tower air cooler with seven heat pipes, which means it can easily handle the heat output of high-end CPUs like the Ryzen 9 7900X3D. Even under heavy loads, it keeps temperatures well under control, making it a great choice for gamers and creators alike.
One of its biggest selling points is how quiet it is. At full speed, the fans barely make a whisper, staying pretty quiet during those marathon gaming sessions. This is perfect for anyone who wants a silent build without sacrificing cooling power. Plus, no fancy RGB here—just pure, raw performance in a sleek design.
The only downside? Size. This thing is huge, so if you have tall RAM modules or a compact case, you might run into clearance issues. But if it fits, the Phantom Spirit 120 EVO is hands down one of the best air coolers for the money.
Pros:
- Excellent cooling performance for the price
- Whisper-quiet operation
- Dual-tower design improves heat dissipation
Cons:
- Large size may cause clearance issues
2. Thermalright Peerless Assassin 120 SE
Quick Highlights:
- Type: Air Cooler
- Fans: Dual 120mm
- Price – $35 – Buy Now
If you’re looking for high-end air cooling without breaking the bank, the Peerless Assassin 120 SE is an absolute steal. It has a dual-tower heatsink, six heat pipes, and two high-quality fans, making it one of the best budget air coolers for high-performance CPUs.
Performance-wise, it goes toe-to-toe with much more expensive coolers. Even under extended heavy loads, it manages to keep the Ryzen 9 7900X3D running cool, preventing thermal throttling without making a racket. It’s also easy to install, which is always a plus.
However, just like the Phantom Spirit 120 EVO, this thing is big. If you have high-profile RAM, you may need to adjust the fan positioning. But if your case has enough space, this cooler offers phenomenal performance at an unbeatable price.
Pros:
- Fantastic cooling at a budget price
- Quiet operation even under heavy loads
- Easy installation for an air cooler
Cons:
- Large size may block RAM slots
- No RGB lighting
3. ARCTIC Freezer 36
Quick Highlights:
- Type: Air Cooler
- Fans: Dual 120mm (push-pull configuration)
- Price – $46 – Buy Now
The ARCTIC Freezer 36 is all about efficiency and silence. Unlike many bulky air coolers, it uses a push-pull fan setup to move air efficiently through its heatsink. This means it can deliver great cooling performance without needing massive fans running at high speeds.
One of the best things about this cooler is how quiet it is. Under load, it’s one of the most silent air coolers available. If you’re building a stealthy, low-noise PC, this cooler is an excellent choice.
However, while the Freezer 36 is great for most users, it doesn’t quite match the peak cooling performance of dual-tower coolers like the Phantom Spirit or Peerless Assassin. If you’re planning to push your Ryzen 9 7900X3D to its limits, you might want something beefier.
Pros:
- Ultra-quiet operation
- Compact design for easier installation
- Push-pull fans improve airflow efficiency
Cons:
- Not as powerful as larger dual-tower coolers
4. Thermalright Frozen Prism 240 Black
Quick Highlights:
- Type: AIO Liquid Cooler
- Radiator Size: 240mm
- Fans: Dual 120mm
- Price – $49 – Buy Now
The Thermalright Frozen Prism 240 Black is one of the best budget AIOs out there, offering solid cooling at a reasonable price. It features a high-efficiency pump, dual 120mm fans, and a sleek black design, making it an excellent upgrade from air cooling without breaking the bank.
Despite its lower price, this AIO performs surprisingly well on high-performance CPUs like the Ryzen 9 7900X3D. Under sustained workloads, it keeps temperatures much lower than high-end air coolers, giving you better thermal headroom. The included ARGB lighting adds some visual flair, making it a good choice for those who want both performance and aesthetics.
That said, fan noise can get noticeable at high RPMs, and while its cooling is great for stock speeds, it may struggle with overclocking compared to premium 280mm or 360mm AIOs. But if you want a solid 240mm cooler at a great price, this is a strong pick.
Pros:
- Excellent price-to-performance ratio
- Sleek black design with ARGB lighting
- Better cooling than high-end air coolers
Cons:
- Fans can get noisy at full speed
- Not ideal for extreme overclocking

While its cooling is impressive for a 240mm AIO, it’s not as powerful as 280mm or 360mm models when it comes to pushing overclocked CPUs. Also, the pump noise can be slightly noticeable at max speed, though it remains quieter than most air coolers.
Pros:
