Koolance is well known for delivering professionally designed and built liquid cooling systems and components and the CPU-330 and VID-282 cooling blocks carry on that tradition. Both waterblocks exhibit excellent build quality and the finest materials. The 24k gold plating on the copper components looks awesome on the outside and provides excellent corrosion resistance on the inside. Performance is right up there with the best and both cooling blocks are relatively easy to install. Just remember to purchase nozzles (tube fittings) to go with your waterblock.
