Description

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:

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 B:
https://www.ebay.com/itm/382694235115
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.
