Coolant Volume and Color Specs
Coolant Volume
The EKWB EK-CryoFuel Premix comes in a 1000ml bottle, while the Mayhems XT1 offers a substantial 5 Litre container. This fivefold difference in volume directly impacts your refilling frequency. The larger Mayhems container is ideal for big loops or multiple builds, reducing the need to purchase multiple units. The EKWB option suits smaller loops or users who prefer to buy smaller quantities more frequently. This choice depends entirely on your loop size and how often you plan to flush and refill.
Coolant Color
Color visibility differs significantly between the two products. The EKWB coolant is Clear, offering a transparent look that lets you see the tubing and components beneath. In contrast, the Mayhems XT1 is Tree Viper Green, providing a vibrant, opaque hue that stands out visually. If you prefer a subtle, clean aesthetic, the clear option is better. If you want a bold, colorful statement piece for your build, the green coolant delivers a more noticeable appearance. Your case window design should guide this choice.
Coolant Type
Both products are premixed coolants, meaning they are ready to use straight out of the bottle without dilution. This convenience saves time and ensures consistent thermal performance from the start. Neither product requires you to mix concentrates with distilled water, which reduces the risk of incorrect ratios. This shared feature simplifies the build process for both users. You can fill your loop immediately, knowing the chemical balance is already optimized for thermal efficiency and component protection by the manufacturer.
Material Compatibility
The EKWB coolant explicitly lists compatibility with Acrylic, PeTG, POM Acetal, and various rubbers like NBR, ePDM, and Norprene. This detailed list assures you of safety with common loop materials. The Mayhems data does not specify compatible materials, though it mentions protection against corrosion and scale. Without explicit material listings for Mayhems, the EKWB provides more transparency regarding which components are safe. If you use specific plastics like Acrylic, the EKWB data offers greater reassurance for your build.
Thermal Performance Focus
Both coolants emphasize thermal efficiency in their descriptions. The EKWB formula is described as thermal efficient, while the Mayhems XT1 is specifically marketed as thermal performance-focused. The Mayhems product also claims the longest operational lifetime, which can help maintain cooling efficiency over time by preventing degradation. The EKWB data does not mention operational lifetime claims. If long-term stability is a priority, the Mayhems claim of extended life may offer better sustained performance, though specific thermal conductivity numbers are not provided for either.
Which coolant suits your loop best
Small loop builders seeking clarity
The EKWB EK-CryoFuel offers a clear color that highlights your components without tinting the fluid. Its 1000ml volume is sufficient for standard setups. The low electrical conductivity and eco-friendly formula provide safety and peace of mind for smaller, visible loops where aesthetics matter most.
Large loop owners needing bulk
The Mayhems XT1 provides a massive 5 Litre volume, ideal for filling extensive custom loops. Its Tree Viper Green color adds visual flair. This size reduces the need for frequent refills, making it a practical choice for builders with large radiators and complex plumbing.
Users prioritizing long term protection
Mayhems XT1 is formulated to prolong component life by protecting against corrosion and scale build up. Its thermal performance focus ensures efficient cooling. The larger 5 Litre container supports long term maintenance, allowing you to top off your loop over time without buying more fluid.

Frequently asked questions
Is 1000ml enough coolant for a custom loop?
Yes, 1000ml is sufficient for small loops. The EK CryoFuel Clear Premix is designed for builders with smaller setups. It provides clear coolant that highlights components without tinting the fluid. You should choose this volume if your loop does not require large amounts of fluid.
Which coolant is best for large reservoirs?
The Mayhems XT1 5L is ideal for large reservoirs. It offers a substantial 5 Litre volume for extensive custom loops. This bulk supply suits builders who need extra fluid for big setups or frequent top-offs. It comes premixed with corrosion protection in a specific green shade.
Do these coolants require mixing before use?
No, both products are premixed coolants. The EK CryoFuel and Mayhems XT1 are ready to use straight from the bottle. This saves time and ensures consistent chemical balance. You do not need to add distilled water or other additives before filling your loop.
What color options are available for clear loops?
The EK CryoFuel offers a clear color option. This allows you to see your components clearly without any fluid tint. The Mayhems XT1 is available in Tree Viper Green. Choose the clear option if you want a neutral look that does not alter the appearance of your parts.
How does coolant volume affect refill frequency?
Larger volumes reduce the need for frequent refills. The 5 Litre Mayhems container lasts much longer than the 1000ml EK option. If you have a large loop, the bulk supply is more practical. Smaller loops can use the 1000ml bottle without wasting excess coolant.
Are these coolants safe for all components?
Yes, both are designed for thermal efficiency and component protection. The Mayhems XT1 includes corrosion protection in its formula. The EK CryoFuel uses an eco-friendly formula with low electrical conductivity. These features help protect your hardware during operation and maintenance cycles.
What is the difference between premix and concentrate?
Premix coolants come ready to use, while concentrates require mixing. Both listed products are premixed, so you can pour them directly into your loop. This eliminates the risk of incorrect dilution ratios. It ensures consistent performance and protection from the moment you fill the system.
Can I use 1000ml for a dual GPU setup?
It depends on your total loop volume. The EK CryoFuel 1000ml suits small loops, which may include dual GPUs if tubing and blocks are minimal. Larger setups with big reservoirs need more fluid. Check your total internal volume to determine if 1000ml is sufficient for your specific build.
