Cryorig C7 is one of the Best Low Profile CPU Coolers while being one of the shortest coolers we have seen so far with a height of 47mm from top to bottom. At 97mm x 97mm, it won’t take up much space. Also, the mounting kit is quite good, although you have to flip the motherboard for the backplate, which is relatively easier. The cooler has a height of 47mm, which may be a bit higher than the Noctua CPU coolers mentioned above, but it will have no problem fitting the smaller mini-ITX or slim case. The width of this CPU cooler is 97mm and it can support processors up to 100W TDP which is good enough for such a small cooler. So if you want a universally compatible low-profile CPU cooler at a low price, take a look at this one. This is another cooler that works as advertised and can handle a wide range of cards with 100w TDP. If you have an Intel system, you are ready to use the 1150, 1151, 1155, and 1156. AMD users are also included with the FM1, FM2 / +, Am2 / +, AM3 / +, and AM4. The C7 is covered for 3 years and offers good value for money.
The C7 is compatible with both Intel and AMD motherboards, but not all C7s come with a bracket that works for AM4 motherboards. However, if you want to use the C7 with an AM4-based version, you can fill out a form on Cryorig.com and they will send you the AM4 upgrade kit for free. Additionally, the 57-fin heat sink is nickel-plated with a copper bottom and four tubes of the highest quality, while the PWM fan comes with high speeds between 600 and 2500 RPM. This is another CPU cooler that meets your demand. It is capable of handling a wide range of cards with a TDP of around 100w.
The Cryorig C7 offers excellent value for money; there is no doubt about it. It’s a clear cut above the stock coolers, both in terms of performance and noise generation, though it’s still far from the quietest cooler when running at top speed.

If you need one of the Best Low Profile CPU Coolers, but aren’t in love with the common design of most compact coolers, you may want to check out the MasterAir G100M RGB Low-Profile CPU Cooler from Cooler Master. With a unique design that looks more like a UFO than a traditional CPU cooler, the MasterAir G100M will likely appeal to many users based solely on its aesthetics.
Cooler Master MASTERAIR G100M is a low profile RGB processor cooler that supports a variety of CPU sockets, including Intel LGA 2066 and AMD AM4 Socket. This low profile CPU cooler has a very unique and modern design compared to other CPU coolers. Instead of having separate heat pipes, this CPU cooler comes with a large copper column about 7 times the diameter of a single traditional heat pipe. This copper column works like a big heat pipe whose base is in direct contact with the processor. The copper column transfers heat from the CPU directly to the circular fin aluminum cooler which is then cooled by a 92mm RGB fan with a PWM connector. Another good thing about its design is that the air from the fan also cools the surrounding components which include RAM or electronic components on the motherboard.
This decibel level is specified at 30 dBA at maximum speed. You won’t need an RGB card as this unit comes with a handy remote control. You might want to take the term low profile not very seriously with this one as the model is 75mm tall which almost doubles the size of other similar options. That being said, it’s a great choice and definitely more compatible than other low profile CPU coolers on the market. Finally, the cooler is guaranteed for 2 years. The only MasterAir G100M fan is quite quiet. So far in our list, be quiet’s Dark Rock Tf has been the quietest of them all. However, the MasterAir G100M does not fall behind. Its noise levels do not exceed 32 dBA, even under high load and high rpm. Cooler Master moves away from the traditional cooler design and brings users the MasterAir G100M – a flying saucer looking for an RGB cooler. It’s easy on the wallet and offers terrific RGB customization. Its wide range of compatibility with AM4 chipsets makes it one of the best low profile Ryzen coolers.
The bottom line is that the Cooler Master MasterAir G100M will provide above average cooling, has a unique design that will likely appeal to some gamers, and comes with RGB lights. If you like the aesthetics of the G100M and don’t mind paying a little extra to get them, then this cooler would be a great option for you.
Thermaltake Engine 27 1U
- Guarantees extremely low noise level without compromising on the cooling performance.
- The ideal CPU cooling solution for slim and small form factor applications, such as 1U server, HTPC,...
- Intel LGA 1200/1156 / 1155 / 1150 / 1151
The Thermaltake Engine 27 is really eye-catching among low profile coolers. What appears to be nothing more than a heat sink at first glance is actually a fully functional CPU cooler, only the fan is also completely aluminum. Even if we put aesthetics aside, the cooler is still efficient, quiet, and one of the most compact coolers on the market. If you have an ultra-compact SFF case with extremely low CPU cooling space, this model might be just what you need. The maximum CPU TDP of 70W is what we would expect from such a compact cooler. Performance is solid, not bad at all, but not exceptional either. Noise levels are in the middle of the pack, hitting around 43 decibels at 100% RPM. Not entirely silent, but not overwhelming.
This cooler is a balance between cooling performance, size, and aesthetics. With this cooler, Thermaltake tried a different approach to air cooling and cooling combined with kinetic cooling. All this is a single metal structure. With a copper base at the bottom, the Engine 27 1U is circular in shape. In the center is a fast rotating aluminum frame that cools the processor. There are 119 fins on the outer frame. The fans are designed to generate maximum air flow and pressure to effectively cool the processor. It measures just 27 mm and weighs 360 grams
What you need to know is that the noise is a high pitched whine and at 100% rpm the noise is unbearable. This is another reason not to use high-end processors with this cooler. It will run at high revs at all times and the noise will probably drive you crazy after a while. We would use this cooler with low power processors, up to 65W, which are not used for big jobs. Sort of like a non-Intel K-based HTPC or SFF gaming PC or a Ryzen 5 3600. Finally, the 27 1U engine is a pretty expensive cooler. Get it only if you really need an ultra-compact cooler of less than 30mm.
The Thermaltake 27 1U motor is Best Low Profile CPU Coolers that is also the most compact cooler on the market with acceptable performance. The all-metal design means the fan is made of metal and built into the body of the cooler. This allows the 27 1U motor to be just 27mm tall, by far the shortest cooler on this list.

The Arctic Alpine 11 GT is one of the Best Low Profile CPU Coolers. It got its place on our list for many good reasons. With multi-plug compatibility, it comes as an easy-to-use unit. The extremely low noise generation is what makes it very popular. Not only is it very reasonably priced, it’s a step ahead of most stock coolers. If you’ve been waiting for an all-in-one cooler that runs quieter and delivers satisfying performance while costing very little, the Arctic Alpine 11 GT is definitely the right choice.
The Arctic Alpine 11 GT is an entry-level, low-profile CPU cooler that was already on our list of the best overall CPU coolers, and the very reasons it landed there also make it the first entry here. Not only is it very affordable, but it is also a small advance over most standard refrigerators. If you need a cooler that is quieter and offers a minor increase in performance, while costing next to nothing, then this is the right choice.
The Arctic Alpine 11 GT is a small upgrade from the original Intel cooler, especially in terms of performance. The denser heatsink contributes significantly to heat dissipation, although this cooler’s biggest advantage over other standard coolers is that it is significantly quieter. Other than that, the only downside is that the cooler is not compatible with the recent AM4 socket. This is more likely a NO for Ryzen users.
