Best 360mm AIO CPU Coolers for Overclocking in 2024

If you have a high-end CPU and are into overclocking, then you do require a powerful CPU cooler that can keep the CPU temperature under check, even at full load. Here, you cannot rely on CPU Air Coolers because even most of the best CPU Air Coolers can only compete against the best 240mm AIOs or 280mm AIOs. So, if you want the best cooling for your processor, then you need to get a 360mm AIO liquid CPU Cooler, which is the largest mainstream AIO you can get for cooling down your processor. Yes, 420mm AIO exists too, but it is very rare, and also, there are not many PC cases that can support it. An example of a 420mm AIO is the Alphacool Eisbaer 420.

A 360mm AIO consists of a 360mm radiator (~396mm in reality), three 120mm fans, and a water block that also houses the pump. The thickness of the radiator may vary as some may have thicker radiators than others. Due to the large radiator or surface area, higher liquid capacity, and triple fans, it can achieve much higher cooling performance than smaller AIOs and CPU Air Coolers. A 360mm AIO is generally fitted on the front of the case because most of the cases offer 360mm radiator support on the front panel only, and it also helps to avoid the clearance issue with other components on the motherboard. These bigger 360mm all-in-one liquid CPU coolers are mainly used for high-end processors with higher TDPs and extreme overclocking.

There are many 360mm AIOs available from different brands, but not all of them offer top-level performance as some 360mm AIOs can even lose out to a good 280mm or even 240mm AIO. So, here I am going to list the best 360mm AIOs that you can get for your gaming or enthusiast PC. Before getting any 360mm AIO, make completely sure that you have a computer case that can accommodate one and has enough clearance for other components.

Best 360mm AIO Liquid CPU Coolers

Here are the top 360mm AIO liquid CPU coolers for overclocking and for high-end processors with higher TDP.

Corsair Hydro Series H150i PRO RGB Liquid CPU Cooler

[Silent Operation, Looks Good, RGB Lighting]

When it comes to AIOs, then Corsair is one of the major players in this area. It makes high-quality all-in-one liquid CPU coolers for all sizes that include 120mm, 240mm, 280mm, and 360mm. Here we have H150i PRO, which is a great looking 360mm all-in-one liquid CPU Cooler. It comes with an aluminum radiator that is relatively on the thinner side. The radiator is cooled down by three 120mm Corsair ML120 series Magnetic Levitation fans that are known for their high reliability and performance. These are PWM fans and spin at 400 to 1600 RPM and generate airflow of 47.3 CFM and static pressure of 1.78 mmH2O, which are pretty good figures. Also, because of such good fans, you don’t have to replace them with other fans, which most of the users do with AIOs that come with mediocre fans. The AIO comes with braided or sleeved tubes for extra protection against cuts and other forms of damage.

The AIO supports all the popular Intel and AMD sockets, including the AM4 and TR4. For the TR4 socket, you have to purchase the bracket additional from the Corsair. The installation of this AIO is very easy, and it uses the modular tool-free mounting bracket. When it comes to the cooling performance, then it beats almost all the high-end CPU Air coolers but does lose out to a couple of top-end 360mm AIOs (e.g., Alphacool Eisbaer 360) and custom liquid cooling kit having the same radiator size. It can handle top-end processors like Core i9 9900K (overclocked at 5GHz on all cores) well under the safe temperature range at full load. The cooler is very silent in operation, and only at full speed, it becomes slightly vocal.

The water block houses the RGB LED that can be customized using the CORSAIR iCUE software, which can also be used to activate Zero RPM mode that stops the fan from spinning under low load for completely silent operation. Using the CORSAIR iCUE software, you can adjust the fan and pump speed, customize the fan curve, set profiles, monitor the temperature, and customize the lighting. So, if you are looking for a silent 360mm AIO that looks great and has enough performance to offer, then it will not disappoint you.

Deepcool CASTLE 360EX Liquid CPU Cooler

[Anti-leak Technology, Good Performance, Stylish, RGB Lighting]

Deepcool CASTLE 360EX is a high-tech 360mm AIO that packs some unique features, which you won’t find in other AIOs. This is a beautiful-looking AIO that comes with addressable RGB LEDs on the CPU water block/pump. The closed-loop liquid cooler (CLC) features Anti-leak technology that prevents the leakage of the fluid by using a pressure releasing mechanism inside the radiator. Inside the radiator, there is an elastic pressure-relief bag whose one side is exposed to the air and the other side dipped in the coolant. When the internal pressure exceeds atmospheric pressures, the bag squeezes and thereby increases the system’s internal volume, which releases the increased pressure, and the risk of leakage is avoided. The pump uses a 3-phase, x-life motor and pressure charging impeller that increases the airflow for better performance. The cooler comes with Deepcool TF120S fans that come with Hydro baring and has a speed in the range of 500 to 1800 RPM. The fans generate a good amount of airflow and static pressure but are a bit loud compared to the competition. However, the pump is very quiet. The CPU water block houses the RGB lighting in the form of a logo, which can be customized and can be twisted for your desired alignment.

The AIO can be used with the majority of the CPU Sockets from Intel and AMD, including the AM4 one. The installation process is fairly simple, and the cooler comes with all the required mounting brackets and screws with it. The cooling performance is very good, and it can easily handle an overclocked Ryzen 9 3900X or Intel Core i9 9900K. The RGB lighting can be controlled using the included RGB controller or by a 5V 3-pin ARGB header via the motherboard’s RGB software. Overall, a pretty nice 360mm AIO that offers great performance and looks astonishing.

Final Words

If you have a top-of-the-line processor with high TDP and are into overclocking then a 360mm AIO is a must if you want to extract the maximum performance out of your CPU. A 360mm AIO may not compete against custom liquid cooling kits with the same radiator size, but it is the second-best thing after it, and also, not everyone has the budget and expertise to set up a custom liquid cooling loop. If you have any queries regarding them, then feel free to ask in the comment section below.
