The Best Low-Profile CPU Coolers in 2023

Keeping your PC running in top condition is about more than clearing up space or looking for memory hogging programs that have run astray. Processors can overheat and are tricky in smaller builds, but if you have the best low profile CPU cooler in your system, you’ll never have to sweat a meltdown.

When your case is cramped, you’re going to need something a bit more svelte than your typical CPU cooler. That’s where low profile designs come into play, and we’ve found several that are standouts if you’re looking to take the temperature down a few notches in your PC.

Choosing the Right Cooler for the Job

Before we get to the best of the bunch, we’re going to go over a few areas in case this is your first aftermarket CPU fan. We aren’t going to cover installation, but our guide will help you find the perfect cooling solution for your processor.

CPU Cooler Style

Unlike the wild world of GPU coolers, there are two styles of CPU coolers for the most part with Liquid CPU coolers and Air-based systems. Both will get the job done, but liquid tends to be the more popular option when it comes to the best low profile CPU cooler for overclocking. A good air cooler can be just as effective however and is considerably cheaper. We’re just going to cover fan and radiator-based air coolers this time around, but this will explain the differences between the two quite nicely.


It doesn’t matter if you’ve got your eye set on an RGB CPU cooler or just want something simple – compatibility is critical. This is one area where things are clear-cut considering the specs you need to know are readily available. If you’re in a rush, be sure to check out the TDP rating along with the height and overall dimensions of the cooler.

With low-profile coolers, height is an obvious stat to keep in mind, and something we’ll list with all of our choices below. While it has nothing to do with compatibility, you’ll want to consider the decibel level as well. Some fans are considerably quieter than others…


Warranties are always important when it comes to PC components although it’s an overlooked area with CPU coolers. They can vary from a couple of years to close to a decade although price often dictates the warranty length.

Interested in a cooler that’s compact but follows the zero interference rule? Well, Cryorig may have the solution for your build with the C7 CPU cooler. It’s designed to steer clear of PCI-E and RAM while keeping your AMD or Intel processor nice and cool.

The Cyrorig C7 is one of the shorter coolers on our list with a height of 47mm from top to bottom.

Cooler Master MasterAir G100M

The Best RGB Low Profile Cooler

cooler master masterair g100m

Fan-based CPU coolers aren’t usually too sassy, especially compared to liquid systems or GPU coolers. The MasterAir G100M from Cooler Master is an exception to that rule, and a colorful option if you’re looking for something with a little more flair.

If you’ve got one of the best CPUs for gaming, you may want a slick looking fan to keep it cool. The G100M fits that bill with its RGB LED system which has several patterns like Mirage and Stars. The company took a top-down approach to cooling with a 92mm PWM fan with speeds between 600 – 2,400 RPM. The decibel level is listed at 30 dBA at max speed, and you won’t need an RGB board as this one comes with a handy remote.

You’ll want to take the term low-profile loosely with this one considering its 75mm high which is twice the size of some options. That said, it’s still an excellent choice and more compatible than other options. For Intel, it works with the LGA 2066, 2011-23, 2011, 1151, 1150, 1155, 1156, 1466 and 776 sockets. AMD users are locked in with the FM1, FM2/+, AM2/+, AM3/+, and AM4. This cooler comes with a 2-year warranty.

  • 130w TDP
  • Wired RGB controller
  • Copper heat column
  • Sweet price point
  • Could be too big for some builds
  • The controller is a bit chintzy

ARCTIC Alpine 12

The Best Budget CPU Cooler

arctic alpine 12

While CPU coolers aren’t what most people would consider expensive compared to other components, some are definitely more affordable than others. The ARCTIC Alpine 12 falls into that category with a budget-friendly price tag and simple, but effective cooling.

This cooler is easy to install compared to other alternatives thanks to a push pin design which means “tool-free” installation. MX-2 has been pre-applied as well, and the radial heatsink design is said to increase cooling capacity considerably. The fan is 92mm with RPWM controls and a range of 100 – 2,000 RPM. There’s also a 0db fan mode below 5% PWM if you prefer to keep your build super silent.

The biggest draw of this cooler is the price tag although we like the 95w TDP rating and the fact it’s easy to install as well. It’s not the smallest cooler at 95mm x 95mm x 77mm but is very light at 270 grams and very affordable. You’re out of luck with an AMD board, but ready to rock if you have an Intel 1150, 1151, 1155, or 1156 socket.

  • Great price point
  • 95w TDP
  • 0dBA mode
  • Easy to install
  • Not AMD friendly
  • Build quality
