2. Cooler Master MasterAir G200P RGB Low-Profile CPU Air Cooler

Runner Up

Cooler Master, like many companies that cater to PC enthusiasts, tends to focus on large, high-end liquid and air coolers.

But because compact systems are a consistent niche, the company occasionally offers up low profile designs to fit those specific needs.

Enter the G200P, a hyper-compact cooler, to accommodate airflow for the smallest of small systems.

With a height of just 39.4mm, the Cooler Master G200P is powered by a single 92mm RGB fan that absolutely shreds air at high RPMs across the cooling fins of its tiny, dual-heatpipe cooler. 

And while this all sounds like a perfect combination of style and small-system performance, the G200P offers more in terms of style than it does in cooling performance.

The MasterAir G200P is a 39.4 mm low-profile CPU cooler designed for small form factor cases and compact PC builds. Built with a powerful 92mm squared PWM fan to maximize top-down cooling, the G200P features a wide fan speed range that is fine tuned for maximum airflow, overall cooling performance or silent operation. ​

The RGB fan is compatible with all RGB motherboards and includes a wired, RGB LED controller, allowing full-color customization.​  

The Cooler MasterAir G200P has two c-shaped heat pipe designs that are strategically shaped for an ultra-compact cooler that maximizes heat dissipation.

Stacked fin placement ensures minimal airflow resistance, allowing cooler airflow into the heat sink. Stacked fin placement ensures minimal airflow resistance, allowing cooler airflow into the heat sink.


  • It provides a great deal of quality
  • Zero memory clearance issues
  • It has a neat design


  • The fan tends to be noisy at high RPM

3. CRYORIG C7 Cu – 47mm Tall, SFF Mini ITX Full Copper CPU Heatsink

Best Premium Low Level CPU Cooler

The CRYORIG C7 is a curiously small CPU cooler that will give your PC a good amount of cooling.

Considering the size of the cooler, you might have doubts as to the performance level of the CRYORIG, but the CPU cooler features a lot of advanced technology that makes up for its size, making it a premium choice for low level CPU coolers. 

This CPU cooler was built with versatile compatibility in mind. It can work alongside a number of components regardless of any form of obstruction. Due to its size, it gives a reasonable amount of space in order for the RAM and other system components to be comfortably fitted with it.

The cooling is nothing short of impressive thanks to CRYORIG proprietary manufacturing processes; the CRYORIG C7 comes packed with a staggering total of 4 high performance copper heatpipes. 

CRYORIG heatpipe technology allows the C7 to be 25% cooler while being 20% quieter than a reference stock heatsink, even though it’s the same size.

The C7’s proprietary 92mm fan comes with built-in Acoustic Vibration Absorber that is the same found on the award winning R1 series ultra-high-end dual tower cooler. By insulating the fan and metal fins, it effectively eliminates all unnecessary vibration.

The CRYORIG C7 is designed to dissipate heat in the CPU and it also does well in reducing the overall heat of your PC, thereby making your computer perform at its best.

4. Cooler Master MasterAir G100M RGB Low-Profile CPU Air Cooler

Small CPU Fan Low Profile RGB Fan

The MasterAir G100M Heat column technology is a two-phase heat transfer that involves the liquid-vapor phase change of a working fluid.

The fluid is transferred by the copper powder filled inside the column creating an anti-gravity heat transfer.

Super quick heat transfer is made possible with the heat column at a massive 41.2, the equivalent of 7 times the size of traditional heatpipes. The unification of heat pipes and base into one unit captures and efficiently transfers the heat from the CPU like never seen before.

The low profile G100M stands at 74.5mm, a great fit for slim PC cases, including mini-ITX cases. Even at these small dimensions, the heatsink has a cooling capacity of 130W TDP.

The high performance 92mm PWM fan, with a range of 600 – 2400 RPM, cools not only the CPU, but all surrounding components inside the case for exceptional thermal results.

The Cooler Master MasterAir G100M RGB Low profile CPU Air Cooler comes with a tool-free mounting kit that makes installation a breeze. Universal retention brackets are included, with full compatibility for Intel.


  • One of the better looking CPU coolers out there
  • It has an overall decent performance
  • RGB lighting and controller included
  • It has a quiet operation


  • Installation is a bit more difficult than most other coolers out there

5. Scythe Big Shuriken 3 CPU Air Cooler, 120mm Low Profile

Best Mini ITX CPU Cooling

Scythe Big Shuriken 3 is built as a cooling solution for small form factor systems like building with an ITX CPU.

You can bring in the BIG Shuriken to dissipate the heat from your CPU, and the CPU cooler always brings a good amount of quality whenever used, on a mini build that is. 

The cooler comes with a new type of technology to further extend its already renowned performance, and it uses the Kaze flex slim fan that delivers great airflow while still remaining as compact as ever.

The wide-space heatsink, joined by 5 sintered heat pipes, can transfer and ventilate the heat effectively, and offset design for better compatibility to all the components on the motherboard.

The Scythe CPU Cooler has unrestricted RAM compatibility with the new asymmetrical heatsink design and revamped cooling fin stack. Big Shuriken 3 has been redesigned to significantly improve compatibility with memory and motherboard I/O covers. 

It is guaranteed to give you no problems with RAM compatibility, making it extremely easy to fit your RAM and many other components of your system with great ease.

And what we like most about the Scythe CPU Cooler is its versatile fan mounting ability, with an additional screw set included. It is absolutely easy to swap regular sized fan blades (25mm thickness) to fit into the cooler for better cooling performance and quieter operation, if space allows.

The new Hyper Precision Mounting System III (H.P.M.S III) guarantees a more convenient and user-friendly installation process as well as perfect contact pressure on all current sockets and platforms. 

With all these new technologies packed into the Scythe Big Shuriken, we had our doubts about how good the promised recent developments would be, but having examined it, we think it’s safe to say that it is pretty much legit. 


  • It has an easy installation
  • Quiet operation during load
  • High performance for so small cooler
  • It is cost effective
  • Full compatibility with tall memory kits
  • No RGB will appeal to some


  • Thermal throttled in OC FPU test

Top Slim AIO Air Cooling Compact Build

Flat Processor Cooler For Compact Build FAQ

Are Low Profile Coolers Worth It?

Generally speaking, low profile coolers are not as effective as regular profile coolers, but again they are meant to be used in mini ITX cases, because some of the regular profile coolers might stop you from installing some other components in your Mini PC, so in a situation like that, you are recommended to go for low profile coolers.

What Is Low Profile Cooler?

The space between the CPU socket and chassis panel are sometimes limited. That is where low-profile CPU coolers come into play. They can keep your CPU cool and still occupy a fraction of space than regular full-sized coolers. They are efficiently designed with high heat removal capacity, and some even offer overclocking potential.

Final Words About The Best Low Profile CPU Cooler
