Aluminum Water Cooling Block, Liquid Water Cooler Heat Sink System for PC Computer CPU Graphics Radiator Heatsink Endothermic Head Silver(40mm x 40mm x 12mm)

It works really well, what I found out with my testing is you can use 6 mm tubing on it and it doesn’t leak at all. It’s a great value for your money. Also, the cooling performance is really good. The only bad thing is it doesn’t come with tubing so you have to get your own.

Almost a single piece of metal. Nice radiator for water cooled gadgets and has many other uses.

This is a good little aluminum water block. I was using it to test cooling capabilities of two thermoelectric coolers and it transfers the heat from the water to chill it nicely! Now if the TEC was just more efficient I would be a happy camper!. the 40mm by 80mm size was perfect to fit two TECs side by side with a little thermal paste it was a great connection. To test how flat the surface was I took a piece of glass and laid it down on it. The surface was so flat you could feel the suction it created by such a uniform surface. Great product!

Couldnt expect anything better. smooth faces, solid block. If you expect anything more, you will be upset, but if you expect a water block, no way you'll be let down.

I had to make my own bracket to screw this down, but with that and a little arctic silver my old nvidia chipset doesn't burn me when I touch it anymore. Adapting a 1/2" cooling solution to port off the flow for this proved challenging but with a couple of 7.2mm G1/4 barbs two Y connectors and a valve, I was able to make an adjustable flow solution.

Great product, I used it with PVC piping that it’s often bought with and it’s not leaky at all. It seems like the water runs through the entire inside of the heat sink and the aluminum comes up to whatever temperature you want it to be pretty fast.

Good quality at a good price

arrived on time and transfers heat quite well. -1 star because I wound up having to insulate it with plaster.
