Build It Right with FTC Watercooling

Custom water cooling is one of the most rewarding ways to enhance your PC’s performance and aesthetics. But whether you’re cooling for silence, thermal performance, or sheer style, it all starts with understanding the essential components of your loop.

In this guide, we break down each key component of a water cooling system and highlight top-quality products available at FTC Watercooling.


? 1. CPU Water Block

At the heart of your loop is the CPU water block—responsible for drawing heat away from your processor.

Top Pick:
? Barrow INTEL CPU Water Block – This multi-platform block supports INTEL X99/X299 and comes integrated with a pump and reservoir for a sleek, space-saving build.


? 2. GPU Water Block

Modern GPUs run hot, especially under heavy loads. A GPU water block directly cools the core, allowing for higher sustained performance and overclocking potential.

Explore Options:
FTC Watercooling carries a variety of Barrow GPU blocks and universal solutions that are compatible with the latest RTX and Radeon models.


⚙️ 3. Pump

Your pump is the engine of the system—circulating coolant through every component. Without sufficient flow, your loop can overheat or underperform.

Recommended Product:
? Barrowch Integrated Pump/Res Combo – This high-performance pump comes paired with a reservoir and CPU block for all-in-one efficiency.


? 4. Reservoir

The reservoir holds your coolant and makes it easier to fill and bleed air from the loop. Larger reservoirs can also help dissipate more heat.

Upgrade Tip:
Consider a transparent or RGB-lit reservoir from FTC for visual appeal in your showcase build.


❄️ 5. Radiator

Radiators are responsible for transferring heat from the liquid to the air. The size and fin density of your radiator will significantly impact cooling performance.

FTC Selection:
Find single, dual, and triple-fan radiators that fit standard 120mm/140mm configurations and offer high thermal dissipation for gaming and workstation builds.


? 6. Fittings & Tubing

You’ll need reliable fittings and tubing to connect everything. Choose between soft tubing for flexibility or hard tubing for a cleaner, more professional look.

Shop Fittings:
FTC Watercooling offers high-quality compression fittings, angled adapters, and tubing kits that match any build aesthetic.


? 7. Coolant

Coolant keeps your system running efficiently while adding color and flair to your loop. Look for anti-corrosive, anti-fungal formulas to keep your system clean.

Pro Tip:
FTC carries pre-mixed coolants in vibrant colors or clear options if you prefer subtlety.
