Overclocking an unlocked CPU gets your gaming PC a lot of extra raw power. It comes in handy whether you want to game or do heavy tasks like video editing. However, overclocking a CPU increases the power draw (TDP) of the CPU. Hence it’s essential to buy a powerful CPU cooler to cool down the CPU and deliver a stable run adequately.

Luckily, you don’t have to spend a ton of money to buy a decent CPU cooler for your overclocked CPU. Some great budget options provide more than enough cooling, along with extra features like low noise level, addressable RGB lighting, high-quality fan, and more.

Here are the top 5 best budget CPU coolers for overclocking:

1. NZXT Kraken Z63

The NZXT Kraken Z63 is one of the most premium AIO from NZXT.

Some notable features of the NZXT Kraken Z63:

  • 280mm radiator liquid cooler
  • 36″ customizable LCD panel on CPU block
  • 2x Aer P 140mm PWM fans included
  • latest 7th gen Asetek pump


The NZXT Kraken Z63 is a premium and gorgeous-looking AIO. The main highlight here is the 2.36″ customizable LCD over the CPU block. It is highly customizable, and you can put your photos or PC metrics for display here.

Since we’re talking about overclocking here, cooling is essential. And it aces here. It provides an outstanding cooling performance for its size as the latest 7th gen Asetek pump is highly improved over its predecessor. The radiator does a pretty solid job of heat dissipation.

CPU Cooler Buyer’s Guide

A decent CPU cooler will go a long way to ensure you have a stable system; your CPU doesn’t overheat or reduce its longevity. Here are the factors you need to keep in mind while buying budget CPU coolers for overclocking:


There are mainly three types of CPU coolers: air coolers, AIO or closed-loop coolers, and open-loop coolers. Open-loop coolers are expensive, complicated, hard to install, and overkill for most people. So you would want to choose between AIO or closed-loop coolers and air coolers.

AIOs come with radiator, pump, fans: all in one package. The liquid coolant is pre-filled, so you just need to screw the liquid CPU cooler in your PC, and you’re good to go. They have more thermal performance than air coolers due to the use of liquid coolant and big radiators.

Air coolers feature a heatsink and fan(s). Typically, they have a lesser thermal capacity, but some excellent air coolers perform as well as AIO liquid coolers.


Between air coolers and AIOs, air coolers are cheaper. Though you get more cooling from the more expensive liquid coolers or AIOs, there are some excellent air coolers available that can get you adequate cooling at a reasonable price.


The very first thing you need to consider while buying a CPU cooler is clearance. You have to make sure the CPU cooler fits in your PC case and motherboard and doesn’t block any VRMs or PCIe slot. Also, make sure you can properly install your memory modules without any obstruction.


Ideally, you would want to have a CPU cooler with more TDP support than what your CPU is consuming. It’ll allow the CPU cooler to have a breathing room and perform more efficiently.


Nobody wants a CPU cooler that constantly bothers with a whirring noise. Decent CPU coolers have optimized pumps and fans with anti-vibration features and quality bearings. These all work together to make sure there is little noise, and it’s not bothersome.


Question: What is the best budget CPU cooler for overclocking?

Answer: The Noctua NH-D15 chromax.Black is the best budget CPU cooler for overclocking. It offers top-notch cooling performance and is capable of handling an overclocked CPU without breaking the bank. It is a reliable CPU cooler praised by tech enthusiasts across the world.

Question: Is a stock cooler enough for overclocking?

Answer: Some stock CPU coolers like the AMD Wraith Stealth Cooler can handle a slight overclock, but overall you should avoid using stock coolers for overclocking. It’ll either cause damage to your CPU in the long run due to increased heat or result in an unstable system.

Question: Is liquid cooling better for overclocking?

Answer: Liquid coolers or AIOs generally provide more CPU cooling performance than air coolers, but they are also more expensive. If you have the budget, liquid cooling is the way to go; otherwise, sticking with a good quality air cooler will be wise.

Final Thoughts

From the list above, which CPU cooler suits your needs? I would take the Noctua NH-D15 chromax.Black any day due to its solid performance and reliability. The NZXT Kraken Z63 is also a top choice if I want a premium AIO liquid cooler with impressive design and looks.
