Aluminum Water Cooling Block, Liquid Water Cooler Heat Sink System for PC Computer CPU Graphics Radiator Heatsink Endothermic Head Silver(40mm x 80mm x 12mm)

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!

This is nice. Solid block of aluminum with drilled channels for the flow.

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.

I like the item I used it for a cooking system

Exceeded expectations.
