Gelid did not implement for the HDT design or any variance of it. Instead we see a rather traditional single piece copper cooling base. The base is un-coated or not nickel plated but is polished to a sheen. All heatpipes are joined together here and soldered in place. The topside of the cooling base is outfitted with an extra heatsink.
The cooler base size is appropriate to ensures that the entire area of the CPU's heat spreader is completely covered.
The heatsink is made up of 40 aluminum fins. The surface of the fins is brushed and uncoated but perforated, which makes the surface rather smooth but with a slightly increased surface area.
The edges of the cooler on the left and right side are bent upwards which acts as a air tunnel and compresses air going through the cooler to accelerate and improve airflow. We can see cutouts for fan spacing in the front. The grooves on the side of the cooler act as the fan clip holder.
The overall shape of the fins reminds on a chevron.
The Gelid Tranquillo Rev2 deploys 4 copper heatpipes. The heatpipes are bent a general "U" shape and have been left un-coated. All 4 heatpipes are 6mm in diameter. The 2 rear most heatpipes also bent slightly backwards to accommodate more space between the heatpipes . This avoids the heatpipes to be to closly staggered behind each other.
The heatpipes are soldered to the base and enter the cooling body through the side of the cooler.
The fan used for this cooler is in the standard line up for Gelid and is listed on the Gelid website. Replacing the fan, should the need arise, should not be a problem. The fan used by Gelid is the Silent 12 PWM (FN-PX12-15) .A 120mm x 25mm variable speed fan.
The fan features a Hydro Dynamic Bearing. The fan comes with a 500mm long 4-pin PWM molex connector which does include a nicely sleeved wire. The fan can generate 58 CFM at a max. speed of 1500 RPM while only generating 25.5 dBA at that speed and consuming 2.16w. The fan also has a standard 7 blade design.
The Tranquillo is on the lighter side of the aftermarket performance coolers. The Tranquillo weights in at 645g without fan. Adding the single included fan pushes this setup to a total of 765g. This just about doubles the 380g of Intel's stock cooler. It will be a noticeable weight gain but far from any dangers levels. Although the mounting mechanism is solid you should proceed with caution when moving the computer.
