Best Liquid CPU Coolers in 2021

Best Liquid CPU Coolers in 2021

There are two methods for CPU cooling, air cooling and liquid or water cooling. Air cooling uses large, loud fans to convey the heat generated by the CPU, while water cooling employs smaller, quieter fans in conjunction with a more effective heat transfer system. The liquid cooling of the CPU is referred to as all-in-one cooling. The Best AIO cooler will keep your CPU and GPU well-ventilated. You can get the maximum performance out of your CPU and GPU when they are properly ventilated.

The water block is linked to the motherboard or GPU in order to transfer heat to the flowing liquid. Because water has a far higher heat transfer coefficient than air, liquid CPU cooling is substantially more efficient than air cooling. Water cooling also eliminates the need for loud fans that spin at high RPMs. Another benefit of adopting water cooling is that your clocks will be more accurate. A water block, tubing, fans, radiator, fittings, and a pump comprise the AIO cooler. Its tubes link the radiators to the water block. Throughout this closed cycle, the fluid is pumped by a pump. The heat is rejected by the radiator, which also serves as a heat sink.

Alphacool Eisbaer Aurora

This AIO cooler brand is extremely wide, providing a variety of designs that provide consumers with copper as a smooth cooling solution. Its most practical feature is refilling, which is why we named it the Best Refillable Liquid CPU Cooler. When compared to aluminum, using copper as a radiator material dramatically boosts heat transmission. The heat transfer coefficients of aluminum and copper vary significantly, although copper takes the lead. The 360mm radiator on the Alphacool Eisbaer Aurora is standard. When compared to its competitors, it has substantially narrower fin spacing, or 15 FPI (which offers 21 fins per inch roughly). Great cooling performance.

Pumps and fans may be outfitted with bright RGB LEDs. It features an illuminated pump block that provides an illuminated view. The build quality is also pretty high and on the rise. It comes with a two-year warranty. Overclocking generates a significant amount of heat, which if not dispersed might harm the CPU’s components. It creates a fluid cooler rather than an air cooler and so cools heat considerably more effectively.

As a result, water cooling boosts your PC’s overclocking capabilities and pushes it to the next level. Water cooling is also more suited for hot climates.

Benefits

  • Radiator constructed of copper.
  • Pump housing that is adaptable.
  • RGB LED digital controller.
  • Better cooling performance

Drawbacks

  • There is no threadripper support.
  • It is a little tricky to install.

Final Words

If you’ve chosen to go with liquid cooling, the Corsair Hydro Series H100i Pro is the best choice since it’s the king of liquid coolers. With the Corsair iCUE software, you can manage your RGB LEDs and fan speeds from a single interface. Fans may even stop when the RPM is set to zero. It is a premium model aimed at high-end gamers, and it is by far the best AIO coolers on the market.

It has the ability to overclock and push your PC to its maximum capability. The EVGA CLC 280mm is the greatest budget-friendly CPU cooler on the market right now. The build quality is also quite commendable. It was a high-level overview and specification of the most cost-effective cooling system.

However, when it comes to the combination of both of these items, Lian Li Galahad takes the lead. It is the best liquid CPU coolers in terms of cooling and price. It contains a fan speed control system that can be set to PWM or DC. It also allows for some overclocking. It also has multi-chamber technology, which increases the efficiency of heat transmission. So, in a conclusion, I recommend purchasing a cooler with a balanced price/performance ratio. The best liquid cooler combines all of the characteristics required by gamers. It is the finest mix of features available within the price range stated. It is the ideal compromise between performance, aesthetics, and cost.

Buying Guide For liquid coolers for your CPU

The following are the most important considerations for providing the optimal cooling for your PC:

Radiator Size

First and foremost, you must choose an AIO cooler that is compatible with your case. 92mm, 140mm, 120mm, 140mm, 240mm, and 360mm are the most popular sizes. The bigger the size, the more effective it will dissipate heat. However, the bigger the radiator, the more room it will need. As a result, it would be advantageous if you made your selection properly.

No. of fans and RPM

The CPU cooler is the loudest component of a PC in terms of fan count and RPM. Large-diameter fans are quieter than small-diameter fans in coolers. It is commonly established that utilizing more cooling fans or fans with higher RPMs can maximize heat transmission, but increasing noise is a turn-off in this case. To address the noise problem, we may utilize additional fans with lower RPM. As a result, it would be advantageous if you choose your water cooling system properly.

Efficiency

If you need to overclock your PC, you’ll need high-end liquid cooling to do it. However, if you are a casual gamer, a mid-range CPU cooler would suffice. Overclocking allows you to push your PC to its boundaries and get the most out of it. However, not every user feels the need for it. As a result, you must choose the best CPU cooler for your PC.

TDP Rating

The amount of heat produced by a CPU or GPU must be removed by the cooling system. To provide the optimal cooling solution for your PC, you must have a cooler with a greater TDP rating than your CPU. The most suitable liquid CPU cooler for your system is one with a higher TDP rating than your processor. As a result, having a big buffer between your CPU and your fan’s TDP is advantageous.

CPU Socket

Various CPU coolers have different sockets, and manufacturers specify this in their catalogs. You must ensure that the CPU cooler you want to purchase is compatible with your motherboard-processor combo. It would be the finest option for a cooler that is fully compatible with your CPU socket.

Air Coolers vs Liquid Coolers

Air coolers are effective at diverting heat away from the CPU but bear in mind that this heat is subsequently spread throughout the chassis. This may elevate the overall temperature of the system. Liquid coolers perform a better job of moving heat outside of the system through the radiator’s fans.

Frequently Asked Questions

Q.Is liquid cooling less noisy than air cooling?

An all-in-one liquid CPU cooler will generally be quieter than an air cooler positioned directly on top of the processor. Because the fans linked to the cooling radiator are often bigger, they may spin at a slower rate than an air cooler. Water pumps are frequently highly insulated, so they don’t make much noise.
However, there are enormous air coolers with massive heatsinks and fans that can compete with the noise generated by an AIO liquid cooler. The most silent of them would be a completely passive cooler with no moving components. However, they are not always capable of handling the most powerful and heaviest CPUs.

Q.Which is superior, an AIO cooler or an air cooler?

In many ways, AIO coolers outperform air coolers. They are more expensive than air coolers but more effective; for example, the Deepcool Captain 240 Pro V2 is aio liquid coolers that offers all the benefits of liquid cooling at a low price, even when compared to an air cooler. AIO liquid coolers have superior heat transmission capabilities over air coolers. They are quieter than air coolers. They are more energy-efficient yet have a great heat dissipation capacity. They provide a greater margin of overclocking for high-end gamers/users.

Q.How do you put CPU coolers through their paces?

The correct CPU cooler, like other components, is determined by a number of factors, including performance needs, case compatibility, budget constraints, and aesthetics. To discover the best CPU coolers, we put them through comprehensive stress testing using Prime95 and a variety of recent PC games. Our best picks were determined on thermal performance, noise, value, and overall feature sets.
