- Slightly tall for smaller cases at 148mm
We recently tested the Thermalright Assassin X120 Refined SE on our Ryzen 5 5600X test bench, and we were genuinely impressed with what this cooler delivers. The four 6mm heat pipes do an excellent job of pulling heat away from the CPU. During our testing, we saw temperatures stay well below the throttling point even under heavy gaming loads.
The cooler’s 120mm PWM fan strikes a great balance between airflow and noise. Running at full speed, we measured noise levels around 25dB – quiet enough that you’ll barely notice it over case fans. The fan’s speed control works smoothly, ramping up only when needed during intense workloads.
Installation was straightforward despite the somewhat lacking instructions. The mounting hardware for both AMD AM4/AM5 and Intel platforms comes included, though we noticed the AMD installation was particularly simple. The cooler’s aluminum heatsink cover not only looks sharp but also helps direct airflow efficiently.
For the Ryzen 5 5600X specifically, this cooler is arguably overkill in the best possible way. Our chip stayed cool even with PBO (Precision Boost Overdrive) enabled, maintaining higher boost clocks than with the stock cooler. The temperature difference was dramatic – about 15°C cooler under load compared to AMD’s included cooler.
We particularly appreciate the AGHP (Anti-Gravity Heat Pipe) technology, which helps the heat pipes perform well regardless of orientation. This practical feature isn’t common at this price point and shows Thermalright’s 20+ years of cooling experience.
Value Comparison: At roughly half the price of premium coolers like the Noctua NH-D15, the Thermalright Assassin X120 delivers about 90% of the cooling performance for Ryzen 5 5600X.
The build quality feels solid overall, though we did find the fan mounting clips to be the weakest point in the design. They work well enough but lack the premium feel of the rest of the cooler. At 148mm tall, it fits in most mid-tower cases, but check your case clearance if you’re using a compact build.

We recently tested the Thermalright Peerless Assassin 120 SE on our Ryzen 5 5600X build, and we’re honestly impressed.
The dual tower design with six copper heat pipes pulled heat away from our CPU remarkably well. During intense gaming sessions, our processor stayed around 65°C, which is about 18°C cooler than the stock cooler.
The build quality feels solid with its aluminum construction. What surprised us most was how quiet it runs. Even under full load, the dual 120mm fans barely make a whisper at 25dB. We could barely hear them over our case fans, which is a welcome change from some of the jet-engine coolers we’ve tested.
Installation took us about 15 minutes. The included mounting hardware works perfectly with AM4 sockets, though you’ll need to use your motherboard’s backplate.
Make sure your case has enough clearance – at 155mm tall, it won’t fit in smaller cases. We found it left just enough room for our standard height RAM, but taller RGB memory might be a tight squeeze.
The AGHP technology (Anti-Gravity Heat Pipe) makes a noticeable difference. We tested the cooler in both vertical and horizontal orientations, and cooling performance remained consistent. This feature helps eliminate the “gravity effect” that can reduce efficiency in some coolers.
For around $40, this cooler performs like products twice its price. We measured temperatures comparable to entry-level AIOs but without the pump noise or worries about liquid leaks. The PWM fans are responsive, ramping up smoothly when needed and staying quiet during light workloads.
Perfect for Ryzen 5 5600X overclocking! We pushed our CPU to 4.8GHz with temperatures still under 75°C during stress tests.

Buying Guide
Choosing the right CPU cooler for your Ryzen 5 5600X doesn’t have to be complicated. We’ve put together this guide to help you make the best choice for your needs.
TDP Rating
The Ryzen 5 5600X has a TDP of 65W, but we recommend getting a cooler rated for at least 95W for better performance. This gives you headroom for overclocking and ensures your CPU runs cooler and quieter.
| CPU Usage | Recommended TDP | Cooling Type |
| Stock settings | 65-95W | Air or AIO |
| Light overclocking | 95-120W | Good air or AIO |
| Heavy overclocking | 120W+ | Premium air or AIO |
Cooler Types
We have two main options: air coolers and liquid (AIO) coolers. Air coolers are generally more affordable and reliable with zero maintenance. Liquid coolers can provide better cooling but cost more.
Size Considerations
Always check your case dimensions before buying. Some large air coolers and 240mm+ AIOs need plenty of space. Measure your case clearance for CPU cooler height if going with air cooling.
Pro Tip: If you have RAM with tall heat spreaders, make sure your air cooler has enough clearance to fit over them!
Noise Levels
Fan size matters for noise. Larger fans (120mm+) can move more air at lower RPMs, resulting in quieter operation. Look for coolers with good noise-to-performance ratios if you value a quiet system.
Budget Considerations
We don’t need to overspend on the 5600X. Since it’s a 65W CPU, even mid-range coolers provide excellent cooling.
Save money for other components unless you plan to overclock heavily.
