Having been using a Gemini High Volume water block, I wanted to make a change as I had felt that the Gemini block was restricting the flow. With its small water channels and small inlet/outlet I thought the Ehiem 1250 was developing backpressure and added heat to the system. So I ordered a D-Tek TC-4 REV 2 block. To my surprise the TC-4 is running 2c delta hotter. The only thing I changed in the entire system was the W/B. I even used the same mounting spring I used on the Gemini. Because the Gemini is thinner. I removed some nylon washers so the pressure applied to the chip was the same on the TC-4.

When I get back from vacation I am going to lap the TC-4 to a mirror finish as I had done to the Gemini. The TC-4 has some small machine marks that everyone claims holds the AS-II in place. My thoughts on this is B/S. The more contact you can place the W/B to the chip the better.
