You are looking at a MOD-ONE vs mayhems water cooling part comparison. These two items serve different roles in a custom loop. One provides the mechanical heart for fluid movement, while the other provides the thermal medium. Understanding their distinct specifications helps you build a compatible system. This guide breaks down the key differences between the Alphacool pump bundle and the Mayhems coolant concentrate.
Key differences
| Aspect | MOD-ONE Alphacool DC-LT 2600 Pump & Reservoir Bundle | Mayhems XT1 250 ml Coolant Concentrate |
|---|---|---|
| Product Type | Pump and Reservoir Bundle | Coolant Concentrate |
| Volume/Flow | 100 L/hr flow rate | 250 ml volume |
| Color | Not listed | Tree Viper Green |
| Weight | Not listed | 10.2 ounces |
Which one should you choose?
Choose MOD-ONE Alphacool DC-LT 2600 Pump & Reservoir Bundle if
- You need a 12V ceramic pump to move fluid through your loop.
- You require a small form factor reservoir top for tight cases.
- You are building the mechanical hardware of your cooling system.
Choose Mayhems XT1 250 ml Coolant Concentrate if
- You need liquid to transfer heat away from components.
- You want a concentrate that prevents corrosion and scale.
- You prefer a specific green color for your coolant visibility.
Verdict: Choose the MOD-ONE bundle if you are constructing the physical loop hardware and need a reliable pump. Select the Mayhems concentrate if you already have the hardware and need the thermal fluid to fill it. These products complement each other rather than compete.
MOD-ONE vs Mayhems Loop Parts
component role
You are comparing two fundamentally different components. Product A is the MOD-ONE Alphacool DC-LT 2600 Pump & Reservoir Bundle. This is a mechanical assembly. It includes a ceramic 12 Volt pump and an Eisstation DC-LT Solo Top. It moves fluid through your loop. Product B is the Mayhems XT1 250 ml Coolant Concentrate. This is a chemical medium. It provides the thermal transfer properties. It does not move itself. You need both parts for a functioning loop, but they serve distinct mechanical and thermal roles.
thermal performance
Mayhems explicitly targets thermal efficiency. The XT1 concentrate is formulated to prolong the life and thermal cooling efficiency of your components. It protects against corrosion and scale build up. This chemical property directly impacts how well heat leaves your CPU and GPU. The MOD-ONE bundle contains no coolant. It is a pump and reservoir. Its specifications list flow rate and dimensions, but no thermal transfer metrics. The coolant provides the actual heat absorption capability. The pump only circulates it. Therefore, the coolant holds the advantage for thermal performance data.
flow rate
The MOD-ONE bundle specifies a maximum flow rate of approximately 100 L/hr. This metric tells you how much fluid moves per hour. It indicates the pump's capacity to push coolant through tight bends and small radiators. The Mayhems coolant has no flow rate specification. Flow rate depends on the pump, not the liquid itself. The data for Product B does not list any mechanical movement metrics. Only the MOD-ONE bundle provides a quantifiable flow rate. This makes it the only option with stated pumping power in this comparison.
coolant color
Color is a key aesthetic choice for custom loops. The Mayhems XT1 is available in Tree Viper Green. The data lists ten color options, including Ozone Clear Blue and Neon Sunset Orange. This gives you visual control over your loop's appearance. The MOD-ONE bundle contains no coolant. It is a pump and top assembly. It has no color specification for fluid. You must buy coolant separately to add color. The Mayhems product provides the color data directly. The MOD-ONE product leaves this entirely to your separate purchase.
physical dimensions
Size matters for small form factor builds. The MOD-ONE pump is compact, measuring 51 x 48 x 9mm. The Eisstation top is 60 x 40 x 40.48 mm. These precise dimensions help you plan tubing and space. The Mayhems coolant bottle is 2.24 x 2.24 x 5.59 inches. It weighs 10.2 ounces. This is a standard bottle size. It does not fit inside your loop. It is a storage container. The MOD-ONE bundle provides internal component dimensions. The Mayhems product provides external packaging dimensions. The pump bundle is more relevant for internal build planning.
compatibility
Both products are designed for standard PC water cooling. The MOD-ONE pump uses a 3-Pin connector. This is a standard fan/pump header connection. It fits most motherboards. The Mayhems coolant is a concentrate. It must be mixed with distilled water before use. It is compatible with standard loop materials like copper and nickel. The data does not list specific material compatibility restrictions for either. Both are general purpose. You can use them together in a single loop. Neither restricts the other's use in a standard setup.
Choose the right part for your loop
Building a custom loop needing fluid movement
You need the MOD-ONE Alphacool DC-LT 2600 Pump and Reservoir Bundle to circulate coolant. This bundle includes a ceramic 12 Volt pump and an Eisstation DC-LT Solo Top. It provides a maximum flow rate of approximately 100 liters per hour. The pump dimensions are compact at 51 x 48 x 9mm, fitting small form factor cases. The top adds reservoir space with dimensions of 60 x 40 x 40.48mm. This is the mechanical heart of your system.
Selecting coolant for thermal performance and corrosion protection
You should choose the Mayhems XT1 Concentrate PC Coolant for its thermal properties. This 250ml concentrate is designed to prolong the life of your components. It protects against corrosion and scale buildup effectively. The specific color is Tree Viper Green. The bottle dimensions are 2.24 x 2.24 x 5.59 inches. This product serves as the thermal medium in your loop, handling heat transfer rather than fluid movement.
Assembling a complete loop with distinct components
You require the MOD-ONE Alphacool DC-LT 2600 Pump and Reservoir Bundle to ensure proper coolant circulation. This assembly features a ceramic 12 Volt pump with a 3-pin connector. It delivers approximately 100 liters per hour of flow. The compact pump size of 51 x 48 x 9mm allows for flexible installation. The included Eisstation DC-LT Solo Top provides necessary reservoir capacity. This component is essential for moving liquid through your system.

Frequently asked questions
Can I mix Mayhems XT1 concentrate with other coolants?
You should not mix Mayhems XT1 concentrate with other brands or types without careful calculation. The product is a 250 ml concentrate designed for specific dilution ratios. Mixing different chemical bases can cause precipitation or reduced corrosion protection. Always follow the manufacturer's dilution guidelines to maintain loop integrity and thermal performance.
What is the size of the Mayhems XT1 bottle?
The Mayhems XT1 bottle measures 2.24 inches in width and length, with a height of 5.59 inches. It contains 250 ml of coolant concentrate. The total weight is 10.2 ounces. These dimensions help you determine if it fits in your storage space or alongside other loop components.
Does the MOD-ONE bundle include a reservoir?
Yes, the MOD-ONE Alphacool DC-LT 2600 bundle includes an Eisstation DC-LT Solo Top, which serves as the reservoir component. It pairs with the compact Alphacool DC-LT 12V pump. This combination is designed for small form factor builds where space is limited and low noise is a priority.
Is the Mayhems XT1 coolant pre-mixed or a concentrate?
The Mayhems XT1 is a concentrate, not a pre-mixed solution. You must dilute it with distilled or deionized water before adding it to your loop. This allows you to control the final concentration level for optimal corrosion inhibition and thermal conductivity based on your specific loop requirements.
What color is the Mayhems XT1 coolant?
The Mayhems XT1 coolant is Tree Viper Green. It provides a distinct vibrant green look for your custom loop. This color is achieved through the concentrate formula, which you mix with clear water. It is suitable for builders who want reliable corrosion protection alongside a specific aesthetic appearance.
What pump voltage does the MOD-ONE bundle use?
The MOD-ONE Alphacool DC-LT 2600 bundle uses a 12 Volt pump. It features a ceramic impeller for durability and low noise. This voltage standard is common in PC water cooling, allowing you to connect it directly to standard fan headers or pump controllers without needing special adapters.
