Best CPU Cooler for i5 8400 in April 2021

Best CPU Cooler for i5 8400 for Best Heat Dissipation!

Keeping your CPU Cool is one of the main tasks when building a PC. No matter how powerful your i5-8400 PC is, no matter how much RAM or GPU you have. If you don’t have proper cooling, nothing will work! Without proper airflow and cooling, your PC will overheat and will die out and lead to physical damage to all the other components. This is why you need a CPU Cooler! In this post, we will find and review the Best CPU Cooler for i5 8400 processor as you came for that only!

People used to take PC cooling for granted a few years back but now as the power of the components is increasing, the trend to build high-end PCs is increasing and one cannot ignore cooling or airflow when the power is too high. CPU Coolers help take the heat out and keep your CPU’s temperature levels under control. This ensures a longer lifetime for the processor and other components as well!

Without a proper cooling solution, you will notice frequent shutdowns of your PC and sooner or later, you will find your CPU to be physically damaged due to excessive heat. This should be avoided at all costs. Investing in a medium-end CPU Cooler will be more beneficial than losing all the components (including your processor) and buying them again.

Since you own an i5-8400 processor, you need a CPU Cooler that will take the heat out and be compatible with your processor’s heating levels and temperatures! For this post, we went ahead and found 10+ CPU Coolers on the market and researched them all. After intense research and several hours and efforts put into it, we shortlisted 5 Best i5 8400 CPU Coolers that will not only keep the heat out but be compatible with your processor’s heating levels!

We have also found and reviewed CPU Coolers for i7-9700k and i7-6700k and you can check them out if you need a cooler for those processors as well! You can find more CPU Coolers by clicking here!

Best CPU Cooler for i5 8400 Reviewed!

Cooler Master Hyper 212 Evo Review

Cooler Master Hyper 212 Evo Review

For starters let us review an affordable yet very powerful CPU cooler that will serve all your cooling needs without breaking your bank. Cooler Master brings some of the best computer accessories and cooling solutions to its customers and the Hyper 212 Evo also lives up to its manufacturer’s name.

Compatible with a range of CPU sockets including the Intel LGA 1366/1155/1151/1150 sockets allowing you to mount the fan to most new generation processors from Intel. The i5 8400 has an LGA1151 socket and this cooler fits perfectly on top of it and is probably the Best CPU Air Cooler for i5 8400 if you are short on budget. Moreover, the package comes with an AMD AM4 (also compatible with AMD FM2/FM1/AM3+.) mounting kit allowing you to use the cooler with the new generation of AMD Ryzen processors.

The cooler uses a Long Life Sleeve Bearing and connects to the motherboard via a 4-pin power connector and the very low power rating of 2.64 watts makes the Cooler Master Hyper 212 Evo very power efficient.

Right out of the box we can already see a pre-installed 120 mm fan sitting on top of the heatsink. The fan appears to be enclosed in a black colored translucent frame and the fan itself is somewhat transparent. Unfortunately, you have to remove the fan before you mount the entire thing on your motherboard. The fan can read speeds varying from 600 rotations per minute all the way up to 2000 rotations per minute via PWM control. The dual-tower design allows you to mount another fan on top to enhance the cooling even further.

The fan is integrated with the CDC (Continuous Direct Contact) technology where the copper heat pipes are kept close to each other allowing for easy transfer of heat and better heat dissipation.

Moving on to the sides the most notable feature of the cooler is visible, the 4 Direct Contact Heatpipes. Unlike most coolers, Cooler Master went with closely spaced flattened copper heat pipes instead of offering a simple block surface. The heat pipes account for a much better heat dissipation and increase the overall cooling performance of the Hyper 212 Evo. The pipes run all the way up to join an aluminum fin on the top while the middle of the fan displays a Cooler Master logo. With all these features the Hyper 212 is arguably the Best Air Cooler for i5 8400 that you can get right now.

Key Features

  • Integrated with CDC technology.
  • Dual mounting system with a pre-installed 120 mm fan.
  • Features 4 Direct contact heat pipes for better heat dissipation.
  • A low power rating of 2.64 watts
