Frequently asked questions
Is this block enough to build a complete cooling system?
No. The block is the cold plate only. A complete liquid loop also needs a pump, radiator, reservoir if used, tubing, fittings and coolant.
What tubing should I use with the 9.5 mm port?
The listed interface outer diameter is 9.5 mm, so choose tubing that fits this port size and secure the connection with suitable clamps to prevent leaks.
