Presentation
Cooljag product ranges include a desktop cooler, but mostly for servers with low-profile CPU coolers for 1U Rack and other types of products. They sent us the desktop cooler, the Sunflower. It is a radiator with a copper base and blades. With the 92 mm-copper ventilation powered by a four-pin connector, the entire cooler’s weight is over 700g.
The pictures speak for themselves as regards the finishing touches, it is very satisfying. It is only compatible with the socket T, but others versions are available for other platforms. Finally, the installation system includes screws, springs and screw nuts.
Installation
The installation starts with the positioning of the reinforcement plate in the back of the motherboard (the studs, close to screw nut level, facilitate this operation).
Then you just need to place the radiator on the CPU to tighten up the whole system. From that point of view, it is almost impossible to mess up the Cooljag installation. The screws’ abutments rest on the motherboard’s eyelet. This solution offers the possibility of carrying out a uniform tightening, if the technique is correctly applied, and it is with the Sunflower.
Measures and results
Below 9V, the rotation speed is too low to measure any temperatures.
Appraisal
It provides very good overall performances but has a high noise level with almost 60 dB(A) at 12 V. The impossibility of lowering the voltage below 8-9 V doesn’t provide an opportunity to reduce the noise level sufficiently.
