40*40 Aluminum Water Cooling Block

Top shelf 40*40mm lapped flat, equally on both sides

Aluminum water blocks for cooling.

We also carry this model with the barbs / ports on top, and larger blocks.

For example:

80*80mm water block - fits 4pcs - 40*40mm chips

80*240mm water block - fits 12pcs - 40*40mm chips

These water bocks partner well with our pumps. We have two very small powerful motors:

Model A: style="font-size: 16px; box-sizing: inherit; margin: 0px; caret-color: rgb(51, 51, 51); color: rgb(51, 51, 51); font-family: Muli, sans-serif; text-shadow: inherit !important;">This model is the smallest and is fully submergible for underwater use with a long wire included. It uses 3/16x5/16 and 5/16x7/16 tubing for input and output, we sell high quality silicone tubing that fits it perfectly and will outlive you.

Model style="font-size: 16px; box-sizing: inherit; margin: 0px; caret-color: rgb(51, 51, 51); color: rgb(51, 51, 51); font-family: Muli, sans-serif; text-shadow: inherit !important;">This one is very powerful and is the same diameter as model A only a tiny bit longer. It is made of a high performance polymer that withstands cold and hot without warping or cracking. Not submersible, use 3/8x1/2 inlet and 1/4x3/8 outlet tubing. It is a beast in a tiny package.

Good luck with your pumping and cooling needs. We also carry the world's best quality TEC1-12715 (for the price) be sure to check it out, it works well with these blocks especially if you run the chips at around 4 volts or even less.

We also carry indium foil gaskets to use instead of thermal grease. Parts need to be compressed to work.

Thank you for choosing Cold & Colder for your cool project.
