Buying Guide
Stop overheating and clogs fast. Real users drop CPU temps 12°C overnight with one switch.
Mark flushed his loop and filled it with XT1 Electric Ocean Blue. "No more brown gunk—just icy, silent performance," he posted.
Choose the right coolant type. Mayhems XT1 boosts thermal performance for demanding systems. X1 is eco-friendly and vibrant for everyday builds. Pick based on your need: max cooling or safety plus color.
Match fluid to your loop material. Coolants with built-in inhibitors protect copper, nickel, brass, and aluminum from corrosion and scale buildup. Always check compatibility—especially with mixed-metal setups.
UV color? Pick what shines for you. Electric Ocean Blue glows under UV. Hot Cherry Pink and Neon Sunset Orange add bold style. Tree Viper Green fits RGB or subtle themes. Color doesn’t change performance, but it transforms your rig’s look.
Use cleaning kits before filling fresh fluid. The Blitz Complete Kit scrubs radiators, blocks, and tubing. Removes old gunk, oxidation, and blockages. Ensures new coolant flows freely and cools efficiently from day one.
Add inhibitors for long-term defense. Hades Plus and Inhibitor Plus (15ml) strengthens any coolant. It stops galvanic corrosion and extends fluid life. A small dose protects pumps, radiators, and blocks for years.
Premixed saves time and prevents errors. Never mix coolant concentrates wrong. Mayhems X1 and XT1 come ready to pour. No measuring. No residue. Just safe, reliable performance in seconds.
Avoid automotive coolants for PCs. Products like Motorcraft VC5 are made for car engines, not water blocks. Stick to PC-specific fluids—they’re tested for seals, plastics, and thermal transfer in closed loops.
Fix leaks with direct-fit parts. The Dorman 603-892 reservoir bolts in exactly as factory. No drilling, no adapters. Stops coolant loss, fits right, lasts under heat and vibration. Ideal for aging vehicle cooling systems.
Keep it simple: Flush, fill, protect. One kit cleans. One bottle of premixed coolant fills. One additive extends protection. That’s how hundreds of builders maintain peak performance without fuss.
Your temps drop the moment you upgrade. Dirty loops choke cooling. Clean fluid with inhibitors flows freely—transferring heat away faster. Lower temps mean quieter fans, longer hardware life, and stable overclocks.
Pick reliability over price. Cheap fluids cause buildup, clogging, and damage. Mayhems solutions are tested, proven, and trusted by overclockers. Pay once for lasting results. No comebacks.
Match volume to your loop. Most builds need 1–1.5L. Larger radiators or multiple blocks use more. Order extra if filling from empty. Running dry ruins pumps fast.
Maintenance is easy with the right tools. Flush old fluid every 6–12 months. Add inhibitor refresh. Refill with premixed. Your loop stays clear, cool, and colorful—year after year.
