Exceptional Silent Cooling Power for Home Lab Servers
Reviewed in the United States on January 6, 2024
Color: AK120SEVerified Purchase
I recently had the opportunity to integrate the Thermalright Assassin King 120 SE CPU Air Cooler into my home lab server setup, specifically catering to a Ryzen 7 1700X processor. After extensive testing, I'm pleased to share my thoughts on its ease of installation, quiet operation, and outstanding performance.
The installation process of the Assassin King 120 SE was a breeze. The package included a comprehensive and well-illustrated manual, making it easy to follow the step-by-step instructions. The mounting system is intelligently designed, ensuring a secure fit without the need for excessive force. Compatibility with the AM4 socket was flawless, and the inclusion of a high-quality thermal paste further simplified the setup. Overall, the installation process was quick, straightforward, and user-friendly.
One of the standout features of the Assassin King 120 SE is its impressive noise management. Equipped with a large 120mm fan, the cooler maintains a remarkably quiet operation even under heavy loads. During my server stress tests, the noise levels remained at a whisper, contributing to a serene working environment. The fan's PWM control allows for dynamic speed adjustments, ensuring optimal cooling performance without sacrificing tranquility. While not completely silent, the noise is well within acceptable limits for a home server setup.
The Thermalright Assassin King 120 SE truly shines when it comes to cooling performance. The dual-tower heatsink design, coupled with its high-quality nickel-plated heat pipes, efficiently dissipates heat from the Ryzen 7 1700X. Even during prolonged periods of intense computational tasks, the CPU temperatures remained impressively low. This cooler is more than capable of handling the demands of a home lab server, ensuring stable and reliable performance. The cooling efficiency also allows for potential overclocking, providing additional headroom for performance enthusiasts.
The Thermalright Assassin King 120 SE is a stellar choice for anyone seeking top-tier cooling solutions for their home lab servers, especially those equipped with processors like the Ryzen 7 1700X. Its user-friendly installation process, quiet operation, and exceptional cooling performance make it a standout option in the air cooling market. Whether you're running resource-intensive applications or pushing your CPU to the limits, the Assassin King 120 SE delivers on its promise of superior thermal management. Highly recommended for home lab enthusiasts looking to optimize their server setups with reliable and efficient cooling.

Easy to Install. Runs well. Amazing for the price.
Reviewed in the United States on March 30, 2024
Color: AK120SE ARGBVerified Purchase
This CPU cooler runs well. I tested it on cinebench and it kept the temperatures low. The stock intel cooler was doing poorly and this fixed all those problems.
I used this to install LGA 1700 CPU. The CPU bracket retention was plastic. Mounting the brackets was straightforward and the cooler itself also easily screwed into the bracket screws. The installation was straightforward.
The CPU cooler has a lot of different shades of grey. The fan is a different grey color and the blades are a dull white, the top of the cooler is dark grey and the sides are unpainted metal color. The mounting hardware have a slightly different shade of color as well. After installing it, the different colors didn't bother me much.
Since the Intel mounting holes are square, I installed it with the fan up. It does pull air and push hot air down to the GPU but it is like that for the aesthetics and I can't fit any fans on the top of the case. I'll probably change it later depending on temperatures and see if there are any problems. Or see if I can find a reverse blade fan to put there. Not sure but that was the configuration that I started with.
Overall, the cooler does a great job. Especially for the price, it brings great cooling at a different price category.

Great little cooler
Reviewed in the United States on July 7, 2024
Color: AK120SEVerified Purchase
I’ve been running one of these coolers for a few months on a pc and love it. I love it so much that I ordered another for a new build. Unfortunately the latest cooler I received didn’t have a flat surface on the plate so it has to go back. It could have been so easy to spot but I guess quality control missed it. There is no love lost here. I’m still giving the one that I’m using 5 stars. It works great but it’s a lottery on if you get a good one or not. Right now it’s 50/50 for me.
Edit: I put this cooler on an Intel 12700k and limited the power to 190watts, the current rating of the cpu, and ran cinebench and this little cooler kept my cpu at 88C. Worked so well that I changed out the fan with a be quiet light wing 2500 rpm fam and I’m getting 82C full load for 10 minutes. Fantastic! I’ll take this over having a ridiculously large twin tower cooler any day.

It works. Quieter than what came with the motherboard.
Reviewed in the United States on June 19, 2024
Color: AK120SEVerified Purchase
This is being used in a 24/7 home server running 6 VMs. The processor is an AMD 8845HS in an ITX motherboard that uses the LGA1700 mounting system. It came with a low profile Jonsbo cooler with a 92mm fan that was noisy. The CPU would warm up and the fan would ramp up just trying to cool it and boy you could hear it. This cooler fit the case 'on paper', and I was quite pleased to see that it did just fine (Thermaltake V1). If it ramps up at all, I sure don't hear it. Nice. I installed it with the fan blowing to the back of the case so the warm air is blown right out the rear case fan holes, and it intakes from the 200mm fan at the front of the case. The CPU has a max configurable TDP of 54watts, but mine is set to the default of 45watts; for this cooler it appears to be a walk in the park.

I got it on a discount for about 23$. I have top say that this is one of the best cooler I've used so far even better than some of the AIO's I highly recommend it. You get everything you need inside to support sockets even thermal paste only thing is missing is a RGB daisy connecter if you want to daisy chain the fans you have to get one separate. 5\5. note: 2 of the small fins were bent a little bit but it was easy to correct it.
