Pros

Cons

The Corsair HydroX XH305i is the perfect water cooling kit to get your new elaborate custom loop underway. This kit comes with everything you are going to need to not only watercool your PC.

This kit comes with:

1 x XC7 RGB CPU Water Block
1 x XD5 Pump Reservoir Combo
1 x XR5 360mm Radiator
1 x XL5 Clear Coolant
3 x QL120 RGB Fans
1 x CORSAIR RGB Fan LED Hub
1 x iCUE Commander PRO
2 x Hydro X Series XF Hardline 14mm OD Fitting Four Pack (Black)
1 x Hydro X Series 90° Rotary Adapter Twin Pack
3m Hardline 14mm Tubing
1 x 10mm Silicone Cord 30 cm
1 x Bending Tool
1 x Deburring Tool
1 x Hacksaw
1 x Cutting Jig

The included radiator is 30mm thick and 360mm in size so make sure you check your PC case has the clearance for this. Additionally, the included RGB fans not only look great but will dissipate the heat from your loop.

One of the main draws to the Corsair water cooling kit is its RGB components. The CPU block looks absolutely stunning and is one of the best looking currently on the market.

Considering how much easier this is going to make the whole physical building process for you, the value isn’t bad at all and you can rest assured knowing every part of this kit is high-quality.

Pros

Cons

Thermaltake is yet another well-known brand that has been producing water cooling components for quite some time now. This kit, like the one before, comes it everything you are going to need to create something special. It is worth noting that this kit doesn’t come with a hacksaw and cutting jig though.

This kit comes with:

x1 Pacific W5 CPU Water Block
x1 Pacific PR15 DDC Pump/Reservoir Combo
x1 Pacific CL360 Radiator
x6 Pacific G1/4 PETG 16mm OD Compression fittings (Black)
x2 Pacific G1/4 90° Adapter (Black)
x3 Riing Duo 12 RGB Radiator Fan
x1 Thermaltake T1000 Coolant Pure (Clear)
x8 V-Tubler PETG 16mm OD 500mm Tubing
x1 Silicone Insert 900mm Tt Premium Edition
Intel and AMD Universal Backplate and Mounting Kit
x1 24pin ATX Bridge Tool
x1 Thermaltake Thermal Paste
x1 Refill Bottle

The Thermaltake Pacific water cooling kit performs exceptionally well and while you can’t see the liquid inside the CPU block as you can with Corsair’s, the design one I quite like.

Unfortunately, you won’t get a hacksaw with this but Termaltake’s included tube cutter works well enough to get you those straight cuts. The included bending kit also has an excellent variety of mandrels, meaning you can achieve more than just 90 degree bends with this kit.

The Best Soft Tubing Water Cooling Kit

EKWB EK-Quantum Power P360 Water Cooling Kit

Cons

EKWB’s Quantum Power P360 water cooling kit is one of the better-known ones out there with EKWB often at the forefront of innovation in this market. This kit provides excellent aesthetics and performance, making it ideal for those who are leaning more towards a soft tube loop.

This highly versatile kit will work with a variety of lighting software and includes:

x1 EK-CoolStream PE 360
x3 EK-Vardar EVO 120ER D-RGB (500-2200rpm)
x1 EK-Quantum Kinetic TBE 200 D5 PWM D-RGB
2m Soft Tubing: EK-DuraClear 9,5/15,9mm (3/8” – 5/8”)

x1 EK-RES X3 – Holder 60mm
x1 ATX bridging plug
x1 EK-Loop Multi Allen Key
x1 EK-Loop Soft Tube Cutter
x1 Foldable Filling Bottle
x1 EK-CryoFuel Dye Pack

As this is a soft tubing kit, there is no need for a lot of tools here and the included cutter is going to be more than enough.

The CPU block features EKWB’s trademark nickel/Plexi aesthetic and it is absolutely stunning when water is running through the loop. The beefy radiator and three RGB fans are going to dissipate heat very effectively at all times and the included filling bottle is slightly bigger than other brands.
