Looking Beyond the DIYhz 120mm 12-Pipe Aluminum Radiator? 6 Alternatives Worth a Look

How these alternatives compare to DIYhz

Clyxgs 120mm Aluminum Radiator with Fan

The Clyxgs 120mm Aluminum Radiator with Fan is slightly thicker at 1.46 inches compared to the DIYhz 1.06 inches. It weighs 10.6 ounces, which is heavier than the DIYhz 7.83 ounces. The extra thickness provides more surface area for heat exchange. You get fans included, whereas the DIYhz requires you to source them separately. This makes it a more complete package for quick builds. If you need a ready-to-install solution with better thermal mass, this is a practical upgrade. The black finish matches the DIYhz aesthetic. It suits users who want a bit more cooling capacity without switching materials.

CLYXGS 120mm Aluminum Water Cooling Radiator

The Clyxgs 120mm Aluminum Water Cooling Radiator is notably thinner at 1.06 inches, matching the DIYhz height but with a different orientation in specs. It lacks the 12-pipe count detail but offers G1/4 threaded ports for direct tubing connection. This model is lighter and designed for tight spaces. The DIYhz uses black oxidation paint for efficiency, while this option relies on raw aluminum construction. You save space and weight with this alternative. It is ideal for minimal loops where every millimeter counts. The G1/4 ports simplify plumbing compared to the DIYhz standard fittings. Choose this if you prioritize compactness and direct connection ease over pipe count.

Clyxgs 120mm Black Aluminum Radiator

The Clyxgs 120mm Black Aluminum Radiator is significantly thicker at 2.28 inches, nearly double the DIYhz 1.06 inches. It weighs more and includes fans, offering a plug-and-play experience. The increased thickness allows for greater airflow resistance and heat dissipation. This makes it suitable for higher heat loads than the DIYhz. You trade the ultra-slim profile for robust cooling performance. The black finish is consistent with the DIYhz look. This option is best for builders who need more thermal capacity in a 120mm footprint. It provides a sturdy, fan-included solution for systems that generate more heat than the DIYhz can handle efficiently.

Alphacool NexXxoS XT45 120mm Copper Radiator

The Alphacool NexXxoS XT45 120mm Copper Radiator switches from aluminum to copper, offering superior thermal conductivity. It is much heavier at 1.32 pounds compared to the DIYhz 7.83 ounces. The steel-cased frame adds durability and protection for the copper core. Dimensions are 6.18 by 4.88 inches, slightly larger than the DIYhz. It features G1/4 ports for versatile tubing connections. This radiator is for users who prioritize material quality and long-term reliability over weight. The copper core handles heat loads better than the aluminum DIYhz. It is a premium choice for enthusiasts who want dense heat exchange in a compact, durable package.

Alphacool NexXxos UT60 120mm Copper Radiator

The Alphacool NexXxos UT60 120mm Copper Radiator is the heaviest option at 1.76 pounds, far exceeding the DIYhz weight. It is also the thickest at 2.76 inches, providing maximum surface area. The copper construction ensures excellent heat dissipation for high-performance components. Dimensions are 4.72 by 4.72 inches, offering a square footprint. This model is designed for enthusiasts who need full copper performance in a single-fan size. It sacrifices the lightweight nature of the DIYhz for peak thermal efficiency. Choose this if you have a high-heat CPU and need the best possible cooling in a compact form factor.

Alphacool NexXxos ST30 120mm Copper Radiator

The Alphacool NexXxos ST30 120mm Copper Radiator is compact at 1.18 inches thick, close to the DIYhz height. It weighs 0.47 kilograms, which is heavier than the DIYhz but lighter than other copper options. The copper core offers better thermal performance than the aluminum DIYhz. Dimensions are 6.18 by 4.88 inches, similar to the XT45. It is designed for small cases where space is limited. This radiator provides a balance between size and cooling capacity.
