The GELID Tranquillo CPU Cooler
The first look at the Tranquillo out of the box played tricks on my camera. This is where the fan is placed and as you can tell, this is where the lab testing starts to show. A few of the more visible design elements are the staggering of the heat pipes, the valley cut into the face of the fins, the texturing done to each of the individual forty fins and a pre-cooler on top of the base. These all play into reducing resistance to the 58 CFM GELID chose to work with.
The side of the Tranquillo uses mostly closed ends. This allows the fins to recapture blow-by that usually escapes open sided coolers. The groove to the right is for the wire fan mounts, and the sides are left open right behind the fan, I would assume to allow for draw of more incoming air; sort of a chimney effect.
The "chevron" look of the fins also carries over the back of the Tranquillo. By redirecting all the air from the sides, by the time it gets to the back of the fins most of the air flow is centralized. Adding the point in the center allows the extra square inches of surface area a bit more efficient.
Looking down on the top the chevron shape is more obvious, as well as the texturing done to the fins. Where the four staggered heat pipes come out of the top, GELID has added a shroud that not only captures more lost air from the fan, but it also is a great platform for the Tranquillo sticker. The choice of black Lexan is a nice contrasting touch.
The base of the Tranquillo does have a pre-cooler atop the heat pipes. Remembering the diagram from the outside of the box, air that escapes under the bottom fin blows across this 35 pin cooler. The four, U shaped heat pipes are fused between the solid copper base and the aluminium top portion with the pre-cooler and mounting holes. There is also evidence of TIM squeezing out from between the two dissimilar metals in the base.
The working end and where all the heat leaves the processor, we get a good look at the Tranquillo's mating surface. The discoloration is what I believe to have been coolant from the milling process. As you can see, the marks from the aluminium to the copper match, and against a razor it is flat across the copper, but the edges tended to bevel up a bit. Neither of these is a big deal, as the IHS mostly sits across the copper portion of the base, and a bit of alcohol made all the spots on the base go away.
Now that we have seen the cooler, let's have a look at this fan. The 120mm fan was specifically engineered to allow for maximum air pressure and reduce the resistance of surface areas on the fan. From the angle of the blade to the texture on both the blades and the fans housing, it is all done to benefit the end user with good performance from a silent fan.
Installing the wire fan clips was a breeze, and as you can see, the white blades of this fan cover quite a bit of surface area. You can almost get a real feel for how the air comes in around the sides and gets directed towards the middle in the rear, and just why the points on the back of the fins are useful.
From the side it is obvious the fan covers all of the fins from top to bottom. With just a bit peeking over the top, you can see that there is a bit for the shroud to capture and utilize, and any excess blowing out the bottom will go right across the pre-cooler.
