DHCR4 vs DHCR1-3
Compare DHCR 4th vs 3rd-1st Gen
The new 4th generation DHCR Cooling Dock includes extensive improvements for a substantial increase in cooling efficiency with the latest Apple MacBook Pro and Air laptops, along with comprehensive optimization for the 2021+ MacBook Pro. The 4th gen’s thermally conductive heatsink silently reduces overall laptop temperatures, while the Fx Cooling Fan boosts peak performance potential for sustained heavy workloads.
The new and improved 4th gen DHCR cooling features are grouped into the following three categories as shown in the diagram above and described below: (1) conductive cooling, (2) heatsink cooling and (3) airflow cooling.
(1) Conductive Cooling
The 4th gen DHCR improves conductive cooling with increased heat transfer from flat-backed laptops like the 2021+ MacBook Pro and 2022+ MacBook Air. This is accomplished with a larger thermally conductive interface for increased surface area, a thinner laptop coupling plate for increased heat distribution, and available for the time time with the 4th gen, direct metal-to-metal laptop coupling for reduced impedance and unrestricted conductive heat transfer.
| DHCR Model Generation | 4th | 3rd | 2nd | 1st |
| conductive coupling surface area (sq.in.) | 13.3 | 12.6 | 12.6 | 12.6 |
| 4th gen percentage improvement | 6% | 6% | 6% | |
| conductive coupling plate thickness (in.) | 0.467 | 0.522 | 1.462 | 1.462 |
| 4th gen percentage improvement | 11% | 68% | 68% | |
| conductive material thickness (in.) | 0.0000 | 0.0099 | 0.0128 | 0.0128 |
| 4th gen percentage improvement | 100+% | 100+% | 100+% |
(2) Heatsink Cooling
The 4th gen DHCR improves heatsink cooling with increased heat transfer from heatsink to passive/active cooling airflows. This is accomplished with deeper and taller cooling fin air channels, increased surface area, and more continuous and interconnected cooling fin air channels for increased heat flow throughout the heatsink.

| 4th gen percentage improvement | 22% | 22% | 22% | |
| curving side depth (in.) | 1.127 | 0.625 | 0.625 | 0.000 |
| 4th gen percentage improvement | 80% | 80% | 100+% |
(3c)New numerous through-hole air channels that extend below the laptop’s bottom edge with a position and angle to guide cooling airflow into the 2021+ MacBook Pro’s center intake. This is an entirely new feature that was not included in prior generations.
(3d)Three new heatsink performance pads help to manage airflows for improved cooling performance. New performance bottom pads feature 1/8” thickness to create a large underside open air channel for improved heatsink cooling. New performance laptop support pad features 1/8” thickness with a center cutout matching the heatsink’s through-holes for improved cooling airflow into a 2021+ MacBook Pro’s central air intake vent, and features side extensions into the horizontal channel’s curving ends.
