Frequently asked questions
Is Mayhems XT1 a ready-to-use coolant or a concentrate?
It is a concentrate. You must mix it with distilled or deionized water before adding it to your loop. This allows you to control the final concentration for optimal thermal performance and corrosion protection. The 250 ml bottle provides enough fluid for most custom builds when mixed correctly.
Can I use the Tree Viper dye with non-Mayhems coolants?
The dye is designed to tint existing fluids. You can add it to clear coolants to achieve the Tree Viper Green shade. It does not provide thermal performance or corrosion protection on its own. You need a base coolant for those functions. Use it only for color adjustment.
What is the difference in size between the concentrate and the dye?
The concentrate comes in a 250 ml bottle. The dye is sold in a much smaller 15 ml container. The concentrate fills your entire loop. The dye is for adding color to a smaller volume of existing fluid. The size difference reflects their distinct purposes in loop maintenance.
Does the concentrate contain the green color already?
Yes, the XT1 concentrate features the Tree Viper Green color directly in the fluid. You do not need to add separate dye. The dye product is a separate item for users who want to tint a different base fluid. The concentrate offers a complete solution with color included.
Which product offers better corrosion protection?
The 250 ml concentrate is formulated for corrosion protection. It contains additives designed to protect components from scale and corrosion. The dye product is a pigment. It does not offer thermal or chemical protection for your loop components. Choose the concentrate for long-term component safety.
How do I choose between the two Mayhems products?
Choose the concentrate if you are building a new loop or need a full refill. It provides fluid, color, and protection. Choose the dye if you already have clear coolant and want to change its color. The dye is for customization only. It does not replace the base fluid.
Is the dye suitable for filling a water cooling loop?
No, the dye is not suitable for filling a loop. It is a concentrated pigment in a small 15 ml bottle. You need a base coolant for thermal transfer and system protection. The dye is an additive. Use it sparingly to tint existing fluid to the desired green shade.
