DeepCool LT720 - Best Value 360mm Kit
The DeepCool LT720 provides 360mm cooling performance at a price between the Arctic and NZXT units. The kit includes three 120mm FC120 RGB fans, the LT720 pump head with an infinity mirror LED ring, full socket mounting hardware for modern Intel and AMD platforms, and thermal paste. Thermal performance in independent reviews is very close to the Arctic Freezer III at a slightly higher price, making it a solid value when the Arctic is out of stock. The installation process is straightforward with well-documented steps. RGB is controlled via the included controller hub or a compatible motherboard header.
Cooler Master MasterLiquid 240L - Best Budget Liquid Cooling Kit
The Cooler Master MasterLiquid 240L is the most affordable complete liquid cooling kit on this list that still includes everything needed for installation. The kit contains the 240mm radiator, two 120mm SickleFlow fans, the pump head with dual-chamber design, a socket mounting kit, and thermal paste. Performance handles mainstream CPUs at stock settings without issue. RGB lighting is present on the pump head. For first-time liquid cooler buyers who want to experience AIO cooling without a large investment, the MasterLiquid 240L is a complete, reliable entry point.

What to Look For in a CPU Liquid Cooling Kit
Confirm the kit includes a mounting bracket for your CPU socket. most modern kits support LGA 1700 and AM5, but verify before buying. Check that thermal paste is included or pre-applied. Assess whether RGB and software control are priorities for your build. Match radiator size to your CPU TDP: 240mm for up to 150W, 360mm for above 150W or if you want quieter fan operation. Read the fan specifications. high static pressure fans are better for radiator mounting than pure airflow fans. Verify your case can accommodate the radiator size in a suitable mounting position.
Final Thoughts
The Arctic Liquid Freezer III 360 is the best complete CPU liquid cooling kit for performance buyers. For a premium 360mm kit with visual impact, choose the NZXT Kraken 360. Budget-conscious buyers should start with the Cooler Master MasterLiquid 240L for a complete, reliable kit at a low price.

Frequently asked questions
What is included in a CPU liquid cooling kit?+
A standard AIO CPU liquid cooling kit includes the radiator with pre-installed fans, the pump and cold plate head unit, pre-filled coolant tubing, a mounting bracket kit for multiple CPU sockets, thermal paste, fan and pump power cables, and installation hardware. Some premium kits add RGB controllers, software dongles, or extra standoffs. Everything needed for installation is in the box. you do not need to source coolant, tubing, or additional fittings separately.
Are CPU liquid cooling kits difficult to install?+
AIO liquid cooling kits are designed for straightforward installation and are appropriate for first-time builders. The general process involves mounting the cold plate to the CPU using the included bracket for your socket, securing the radiator to a case fan mount, connecting the fans and pump to the motherboard headers, and routing cables. Most installations take 20 to 40 minutes. The trickiest part is usually managing cables and ensuring the radiator is mounted in the correct airflow orientation.
Do liquid cooling kits come with thermal paste pre-applied?+
Most AIO liquid cooling kits include thermal paste, either pre-applied to the cold plate or in a separate syringe for manual application. Pre-applied thermal paste is convenient and performs adequately for most users. For maximum thermal performance, some enthusiasts clean the pre-applied paste and apply a premium compound like Thermal Grizzly Kryonaut instead. Either approach works well. the pre-applied paste on quality AIOs performs close to premium aftermarket compounds.
