Ever since Zalman had released their line of radial heatsinks that broke away from the traditional heatsink design, other manufacturers have been trying to follow in the success. Prime Cooler recently presented our staff at Phoronix with an opportunity to examine two heatsinks that resemble the original Zalman radial heatsinks. However, there are a few differences, which should lead to some interesting results. Today we have the opportunity to examine Prime Cooler's Hypercool III+ and 4+.
|Hypercool III+||Hypercool 4+|
|Dimensions:||144 x 144 x 65 (mm)||144 x 144 x 65 (mm)|
|Bearing Type:||Dual ball||Dual ball|
|Airflow:||53.5 - 78.5CFM||53.5 - 78.5CFM|
|Fan Speed:||1200 - 2500RPM||1200 - 2200RPM|
|Fan Noise:||15 - 30dB||15 - 25dB|
After opening both the Prime Cooler Hypercool III+ and 4+, we found roughly the same contents in both. A few included parts are installation instructions, mounting brackets, screws, shims, thermal grease, and a speed controller. The main differences between the Hypercool III+ and 4+ in contents is that the Hypercool 4+ provides the mounting clips for attaching the heatsink to an Intel Socket T LGA775 processor. Unfortunately, a rather generic fan speed controller is included. The little speed controller which is commonly found in cooling solutions allow you to adjust the voltage going to the fan, thus changing the speed at which the fan runs to customize the noise output/air flow. The installation instructions provide detailed information on mounting the heatsink with the different sockets.
