1. DeepCool AK620
Best Pick
The DeepCool AK620 is a high-end cooling solution for Intel and AMD processors. I’ve used many cooling solutions, but this is the best.
It supports the latest Intel and AMD processors, which is important for me. I also want my cooling solution to be powerful and reliable.DeepCool is well-known for making top-quality cooling solutions, and the AK620 is no exception.
It has 6 heat pipes to transfer heat efficiently and a dense fin array to prevent any hot spots. The heat pipes are made of copper and nickel plates. They are also covered with thermal grease to ensure smooth heat transfer.
I like the dual-tower design. It allows for better heat distribution and for the fans to be placed in the best position. The fans have a PWM design, so you can adjust the speed to suit the situation.
It’s important to note that the fans are not included, so you’ll need to get them separately. If you’re looking for a powerful yet silent cooling solution, then the DeepCool AK620 is worth a look.
Pros
- Super quiet operation
- Large base to increase stability
- The stable and solid base design
- Strong aluminum frame
- Includes a 240-watt power supply unit
- Two-year warranty
Cons
- The fan speed is not adjustable; only two speeds
- No fan controller
2. Noctua NH-U12A chromax.Black
The Noctua NH-U12A is one of the best CPU coolers on the market, and it’s designed for high-end processors like the Intel Core i9, i7, i5, i3 (e.g., 12900K, 12700K, 12600K) and AMD Ryzen (e.g., 7950X, 7900X, 7700X, 7600X).
I use this for my rig to get the most out of my processor. It’s a great case, has RAM and PCIe compatibility, and doesn’t overhang the RAM slots on LGA17xx, LGA1200, and AM4, so it doesn’t block the PCIe on most ATX and Micro-ATX motherboards.
The Noctua cooler is a bit bulky, but that makes it easier to install and removes the risk of scratching your motherboard. It’s also a bit noisy at idle, but the fans are efficient and can provide decent cooling even under heavy loads.
With a 6-year manufacturer’s warranty, Noctua is one of the most trusted brands on the market. I’ve had the NH-U12A for over a year, and it’s still strong.
Pros
- Highly efficient fans
- Premium components
- Clean and quiet; suitable for gamers
- Low-noise operation
Cons
- Expensive
3. NH-L9a-AM4 chromax.black
Staff PickNoctua’s NH-L9a-AM4 is one of the best low-profile CPU coolers we’ve tested, and it’s a great choice for AMD AM4 users with small form factor (SFF) builds.
The Noctua NH-L9a-AM4 is an SFF CPU cooler that can fit on an AM4-compatible motherboard without requiring additional holes. It has a compact footprint of 37mm, which makes it ideal for small form factor (SFF) builds and HTPCs.
While most coolers are tall and wide, Noctua’s NH-L9a-AM4 has a small footprint and a low profile. That means it won’t take up much space and is better suited for SFF builds and smaller form factor (SFF) builds.
You can use the NH-L9a-AM4 on any AM4 motherboard with 100% compatibility. The cooler uses low-profile fans and near-socket connectors for maximum compatibility. It also has a low-profile, Low-Noise Adaptor (LNA) fan and automatic speed control.
The Noctua NH-L9a-AM4 has a silent, premium-grade NF-A9x14 fan with a maximum rotational speed of 2000rpm and a Low-Noise Adaptor (LNA) that automatically adjusts fan speed based on ambient temperature. The fan is quiet and produces less than 27 dBA at idle. It can handle up to 95mW at full speed, which should be plenty for modern processors.
The NH-L9a-AM4 is compatible with all AMD Ryzen and Ryzen Threadripper CPUs and the latest generation of AMD APUs (Ryzen 3rd Gen, Ryzen 5th Gen, Ryzen 7th Gen, and Ryzen Threadripper). It has a 6-year warranty, and Noctua provides a 30-day money-back guarantee.
Pros
- Easy to install; built-in screw holes make it easy to mount
- Compact design; can be installed on small form factor motherboards
- Sleek and modernistic look
- Offers interference-free wireless connectivity with low latency
Cons
- Some users may find it difficult to install; does not include screws
- Not compatible with Intel Z270 or H270 motherboards
4. Arctic Liquid Freezer II 240mm
The Liquid Freezer II has many nice features, including being compatible with both Intel and AMD processors. The LGA1700 compatible cooler has a pump that is efficient and cool, and it’s PWM controlled so that you can adjust the speed of the pump with the push of a button.
The cooler is a nice-looking piece, too. The front of the cooler has two 120 mm fans and a pump. The back of the cooler is where the main radiator is located. There’s a 120 mm fan there too, and there’s also a small fan on the bottom of the cooler. The PWM cable of the fans is integrated into the sleeved tubing, which makes the cables look cleaner.
The cooler is also maintenance-free, which is great. There’s no need to refill the water tank now and then, and there’s no need to clean the radiator and pump.
This well-made cooler does a good job of keeping the CPU at the right temperature. The pump and fans are efficient, and it’s also a very quiet cooler. The water loop is also sealed and maintenance-free.
Pros
