The EVERCOOL Transformer 4 – HPJ-12025 is a medium sized heat sink measuring 130 x 122 x 160 x mm (l x w x h) with fans installed. It stands 160 mm tall and weights 843.5 g – not too heavy.
The EVERCOOL heat sink is constructed around four copper 8mm heatpipes, fifty large aluminum fins, and Heatpipe Direct Touch (H.D.T.) base providing effective cooling.
The four heat pipes are stacked side-by-side at the aluminum base, with small strip between each. The base is not mirror finished but flat (matte).
The ends of the heat pipes are finished with aluminum caps at the top of the cooler. Here you can find the Transformer 4 logo and slogan stamped into the top fin.
Declared power consumption is 12 V DC and 0.32 A, providing long life bearing and rated speed 800~2200 RPM (PWM) at less than 17 dBA noise level. Unfortunately, there is no fan CFM specification available at product page but after short seeking among EVERCOOL fans max airflow is specified as 78.41 CFM . The fans are silver – chrome, the same as aluminum fins to give a nice uniform look. Each of the 120mm fans are secured using two metal clips.
“There are however a few issues. First of all, we had a problem with the layout of the back plate corresponding holes doesn’t match the LGA 1156 motherboard, therefore we used a backup backplane instead. The picture shows this issue with the backplane laid at the CPU socket to be better visible. We contacted the EVERCOOL about this issue and they promised to check it.”
Instead of that I would like to comment the installation of the cooler without the back plate:
It’s not usual to have such a big custom cooler installed without the back plate to support the weigth. You guess, the back plate is not intended to be used for installation of the Transformer 4 to socket 1156 motherboard. That has the pros and cons but in the end, we have to trust the installation guide and to Evercool’s engineers on this. If you value a simplicity of the installation then you know what we are talking about here. From the overclockers point of view, the luck of the back plate means the less pressure can be used and that means lower overclocking speeds.
