Comparing the Mayhems Cooling Lineup
The lineup splits primarily between ready-to-use fluids and self-mixed concentrates. If you want direct fills without measuring pure water, premixed options like Mayhems XT1 Premixed Coolant 1 Litre fit standard desktop loops. For high-capacity multi-radiator systems requiring larger volumes, Mayhems XT1 Premixed PC Coolant 5 Litre eliminates measuring steps while providing scale and corrosion inhibitors directly from the bottle.
If you prefer managing your own dilution ratios or need specific additives, concentrates like Mayhems XT1 250 ml Coolant Concentrate pair with Mayhems Ultra Pure H2O 5 Litre Liquid for custom mixtures. This category also includes dedicated loop preparation kits and standalone dyes, which suit builders performing system flushes or custom shade adjustments.
Who the Mayhems Range Suits
This range suits you if you maintain or refill custom liquid cooling loops. Container sizes scale from a 15 ml dye bottle to 5 Litre jugs. Fluid colors cover Tree Viper Green and Neon Sunset Orange, alongside pure H2O.
You must note the hardware gaps. The catalog includes zero all-in-one cooling units, radiators, tubing, or pumps. You find no lighting or RGB additions. The selection also lacks intermediate container sizes between 250 ml and 1 Litre. The listed items solely provide fluids, colorants, and loop-flushing treatments for open loops.
How to Choose Mayhems Cooling Products
-
Pre-Fill System Cleaning
Residual flux or contaminants inside radiators ruin fresh coolant quickly. You need dedicated cleaning chemicals before adding your primary fluid. Check if you require full loop flushes or basic rinses. The Mayhems Blitz Part 2 System Cleaning Kit includes 125 ml of specialized Blitz Part 2 solution alongside testing accessories to clean an assembled loop. This process stabilizes loop chemistry prior to adding coolants. Using a flush kit prevents debris from clogging microchannels.
-
Base Water Electrical Conductivity
Diluting concentrated coolant requires pure water rather than tap or standard distilled water. Check the electrical conductivity ratings on the spec sheet before mixing. Lower conductivity reduces early ionic contamination and electrical hazards around PC components. Mayhems Ultra Pure H2O 5 Litre Liquid provides reverse-osmosis filtered water with an electrical conductivity under 1 microsiemens. Selecting water with verified low conductivity ensures that concentrates mix without introducing minerals. Minerals cause buildup, reduce heat transfer, and exhaust corrosion inhibitors prematurely.
-
Eco-Friendly Formulation Chemistry
Coolant formulations differ in chemical makeup and environmental impact. Review the fluid base material to see if it relies on conventional chemicals or plant-derived ingredients. For builds requiring non-toxic fluid disposal, seek vegetable-extract bases. Mayhems X1 Neon Sunset Orange Concentrate 250 ml utilizes a biodegradable vegetable-extract formula while providing corrosion protection. Choosing biodegradable options makes routine maintenance and fluid draining safer for your home environment. Match the fluid formula to your loop maintenance habits and disposal preferences.
-
Targeted Color Adjustment
You do not always need to replace an entire loop of clear or light fluid to change loop aesthetics. Dedicated dye concentrates let you adjust fluid tint in small increments. Check the bottle size and dropper format to avoid over-saturating your loop. Mayhems 15 ml Tree Viper Green Coolant Dye provides concentrated color additive in a compact 15 ml bottle for targeted color adjustments. This allows you to tint compatible coolants without throwing off chemical balances. Use small dye volumes to control color intensity precisely.
-
Internal Scale Protection
Custom cooling loops mix various metals and run at warm temperatures, encouraging mineral scaling and surface oxidation over time. Check the coolant specification for scale inhibitors alongside standard anti-corrosion additives. Formulations with scale protection keep internal fin channels clear of hard mineral buildup during long runtimes. Mayhems XT1 250 ml Coolant Concentrate specifically includes scale protection and corrosion defense in its concentrated formula. Choosing a coolant with active scale resistance protects pump impellers and radiator waterways, preserving flow rates over multi-year cooling cycles.
