Bykski GPU Block vs Pump Bundle
Coolant Color
You can see the fluid level and clarity with the Bykski Galax RTX 2070 block. Its clear top lets you monitor the coolant directly. The MOD-ONE Alphacool DC-LT bundle does not list a specific coolant color for the pump or reservoir. You will need to check the Eisstation DC-LT Solo Top specifications separately if visibility matters to your build. The Bykski option provides immediate visual feedback on the liquid state.
Dimensions
The Bykski GPU block is a large component measuring 11.8 inches in length and 7.11 inches in width. It weighs 3.7 pounds. The MOD-ONE Alphacool DC-LT pump is much smaller at 51 x 48 x 9mm. Its top adds height but remains compact in footprint. The pump bundle is designed for small form factor cases where space is limited. The GPU block requires significant clearance on the graphics card.
Build Material
The MOD-ONE Alphacool DC-LT pump is explicitly described as ceramic. This material choice affects durability and thermal properties. The Bykski block is labeled as clear but the specific base material is not stated in the provided data. You might assume standard nickel or acrylic for the GPU block, but the ceramic construction of the pump is a distinct feature. This makes the pump material easier to verify from the listing.
Flow Rate
The MOD-ONE Alphacool DC-LT pump specifies a maximum flow rate of approximately 100 L/hr. This gives you a clear expectation of water movement through your loop. The Bykski GPU block is a passive component. It does not move fluid, so no flow rate is listed. It relies on the pump for circulation. The pump data provides a concrete performance metric that the block lacks.
Compatibility
The Bykski block is designed specifically for the Galax RTX 2070 Gamer graphics card. It offers full coverage for that specific model. The MOD-ONE pump bundle is a general loop component. It uses a 3-Pin connector and fits standard reservoir tops. The pump is not card-specific. However, the GPU block has strict compatibility limits. You must have the exact Galax RTX 2070 Gamer card to use it.
Which Bykski or MOD-ONE part fits your loop
You need full GPU cooling coverage
The Bykski block covers the entire Galax RTX 2070 GPU surface. Its dimensions of 11.8 by 7.11 inches ensure broad contact. The clear top allows you to monitor coolant clarity directly. This full coverage design targets efficient heat transfer from the graphics card core and memory.
You want a compact pump and reservoir
The MOD-ONE bundle provides a small form factor pump measuring just 51 by 48 by 9mm. It pairs with a slim Eisstation top. This setup fits tight cases better than larger reservoirs. The 3-pin connector offers flexible power options for your build layout.
You prioritize high flow rate performance
The included Alphacool DC-LT pump delivers approximately 100 liters per hour. This flow rate supports efficient heat removal across your loop. The ceramic 12V motor ensures consistent performance. This bundle focuses on moving coolant effectively rather than just cooling a single component.
