HP-1204S on the left and HP-1204S-X on the right.

The Same as HP-1204S, HP-1204S-X also uses DTH (Direct Touch Heatpipe) design. This is the biggest selling point of PCCOOLER’s CPU cooler. With the design the heat can directly emit to heatpipe, and transit to the fin by the stream inside the pipe.

DTH

8mm heatpipe

This is another selling point, the 8mm heatpipe. Let’s see some facts first. If the heatpipe is 150mm long and the diameter is 3mm, then it only can transit 5.4watt heat in one heat transmission cycle. But when the diameter enlarge to 5mm then it can transit about 25w in a cycle. And if the heatpipe’s diameter is 8mm, then it can transit as high as 133W heat! So that’s why Thermalrhgt IFX-14, Gigabyte G-Power series, and other high end cooler product all equipped with 8mm heatpipe.

But 8mm heatpipe’s good performance requires a larger area and a nice design of fin. Because if the wasted heat keep transit to the fin, and the design of the fin can not emit the heat efficiently, then 8mm heatpipe is petty useless.

Fin penetration design

The connection between heatpipe and fin is using Fin penetration design. It is a cost saving design, But not as good as welding.
