These days, most graphics cards come equipped with complete cooling solutions. However, most of these solutions have certain drawbacks. They’re either too loud, or aren’t efficient enough to cool the GPU at default settings, let alone when it’s overclocked. This can be quite an issue, especially if you are a serious PC enthusiast trying to squeeze out the best performance out of your graphics card, or you are a cryptocurrency mining entrepreneur who wants to optimize the cooling of your mining equipment, and extended its lifetime as much as possible. Fortunately, there is a solution for this kind of problem, and it’s available in a form of aftermarket GPU coolers.

Almost a decade ago, aftermarket GPU coolers were extremely popular. This was due to the fact that most graphics card manufacturers produced very inefficient cooling solutions for their GPUs, and aftermarket coolers offered better heat dissipation than stock coolers. Nowadays, most GPUs already come with decent cooling systems. However, when it comes to overclocking, almost any high-quality aftermarket GPU cooler will outperform any stock GPU cooler.

But aftermarket GPU coolers aren’t just useful to users who prefer overclocking their graphics cards. They are also very useful to users who use their GPUs for mining cryptocurrencies. If you mine Ethereum (ETH), or any other cryptocurrency (e.g. Ergo), then you know how stressful can it be for your graphics cards to mine 24/7. Continuous operation and heat kill graphics cards, and investing in proper cooling equipment is necessary if you want to keep your GPUs running cool, quiet, and as long as possible. For that reason, buying an aftermarket GPU cooler is mandatory, especially if you want to preserve your mining equipment.

Just like the CPU cooler, the main purpose of a GPU cooler is to draw the heat away from the GPU’s core and its other components such as VRM and memory modules. GPU coolers come in three different forms: air coolers, AIO (all-in-one), and blowers. Structurally, air coolers are very similar to ordinary CPU coolers, as they consist of a heatsink with heat pipes and fans. Blower coolers are designed to suck out the hot air and push it out. They are very basic, and fairly efficient, but extremely loud. AIO coolers, on the other hand, have liquid cooling loop and a radiator. These coolers are the most efficient, and the most silent, but also the most expensive.

In short, if your GPU is overheating, or is simply very loud due to an inefficient cooler, getting an aftermarket GPU cooler is a much cheaper option then buying a new GPU these days. Down below you can check out the best aftermarket GPU coolers you can buy today.

Although it’s not a proper GPU cooler, but only a GPU mounting bracket for liquid cooling AIOs, the Kraken G12 is our top pick when it comes to aftermarket GPU coolers. The Kraken G12 is essentially an installation bracket that allows you to mount almost any NZXT Kraken all-in-one liquid cooling system directly to a GPU without the maintenance of a custom loop. This means you can mount widely popular and extremely efficient AIOs, such as Kraken Z73, Kraken Z63, or Kraken X63 onto your GPU to improve cooling and reduce noise.

The Kraken G12 is compatible with over 30 liquid coolers and 40 different GPUs, including NVIDIA GeForce RTX 20 series and GeForce GTX 10 series GPUs, as well as AMD Radeon RX 500, RX 400, R9 300, R9 200, and HD 7000 series graphics cards. On average, the Kraken G12 is able to provide 40% better cooling than the stock GPU cooler, and it also features a 92 mm fan for active VRM cooling with space for aftermarket coolers. This cooler is available both in black and white color, and its only two drawbacks are its somewhat large dimensions and incompatibility with non-reference graphics cards.

Best Air GPU Cooler: Arctic Accelero Xtreme IV

Compatibility: NVIDIA GeForce RTX 2080 (Ti, Super), RTX 2070 Super, GTX 16, GTX 10, GTX 900, GTX 700, GTX 600, GTX 500, GTX 400; AMD Radeon RX 5700 (XT), RX 500, RX 400, R9 300, R9 200, HD 7000, HD 6000, HD 5000, HD 4000, HD 3000 | Base Material: Aluminum | RGB: No


  • Fantastic cooling performance
  • 300 watts cooling capacity
  • Three PWM fans
  • Compatible with over 50 GPUs
  • Great acoustics

The Arctic Accelero Xtreme IV is an incredibly powerful GPU cooler, and as such is considered to be one of the best aftermarket air GPU coolers ever made. With a cooling capacity of 300 watts, this cooler can deliver unmatched performance, and can lower temps by more than 30 degrees Celsius on some graphics cards, including the GeForce GTX 1080 Ti. It is also worth mentioning that this cooler comes with three 92 mm PWM fans, and features pre-applied Arctic MX-4 thermal paste to ensure efficient cooling, even under overclocking.

Supporting more than 50 different graphics cards, this GPU cooler is incredibly versatile, and features a free mounting system for easy installation. However, this GPU cooler does have some drawbacks. Firstly, it absolutely huge. Measuring 288 mm in length and 104 mm in height (without backplate!), this cooler is only feasible for installation in big tower PC cases. Second, it is quite expensive, but given its fantastic performance, its price is well-justified. In short, if you are in need of an overkill GPU cooler, then Artic Accelero Xtreme IV is your best bet.

  • Made of plastic
  • Requires free PCI slots

Anidees RGB VGA cooler is a budget graphics card cooler designed to be used for cooling down weaker GPUs, such as GeForce GTX 1660 series or Radeon RX 5500 series graphics cards. This cooler isn’t mounted directly on top of a graphics card, but is inserted into a PCI slot below the graphics card which you want to cool. What this cooler basically does is that it increases overall airflow within your PC case, and thus feeds your GPU’s stock cooler with more fresh air to improve cooling.

The Anidees VGA cooler features three 80 mm dual ring fans with 12 independent RGB LEDs which support rainbow and static colors. The cooler also comes with a remote controller which allows you to adjust fan speed, as well as customize RGB lightning.
