Your PC will run cooler and quieter when you replace your CPUâ€™s standard heatsink with a Hydro Series H45. Installation is straightforward: if you can get to the back of your PCâ€™s motherboard, you can install an H45. All youâ€™ll need is a screwdriver. The compact components and flexible tubing make Hydro Series H45 easy to install even if youâ€™re cramped for space. It allows you to improve your CPUâ€™s cooling efficiency even in most compact cases â€” as long as your case has a 120mm fan mount near the CPU, the H45 will probably fit. Serious liquid cooling for high-performance CPUs no longer means dealing with complex plumbing. Hydro Series H60 comes pre-filled, and never needs refilling or priming. Minimal coolant evaporation helps ensure long life, and the resilient rubber offers both high flexibility and excellent leak protection. The pump unit provides high-speed circulation without taking a lot of space. This makes installation easier, and helps improve your caseâ€™s airflow. Copper has better thermal conductivity for more efficient heat transfer to the manifold. Pre-applied thermal compound lets you save a potentially messy installation step.
