The contact surface of the base is decently finished. Although you can visually identify machine marks on the base surface, it is very smooth:
It is also impeccably even:
Actually, the Fiend Shark UF140 fan has been slightly “enhanced”: its maximum rotation speed is 1400 RPM, instead of 1200 RPM by the original model. At this speed it should create 80.28 CFM airflow and generate no more than 32 dBA of noise. The minimal fan speed is 700 RPM thanks to PWM support, and the level of generated noise in this case is 18.2 dBA.
The fan is attached to the heatsink with two wire clips catching on to the retention holes in the fan frame:
Since UF140 has special anti-vibration lining, there is no need for any additional vibration-absorbing solutions between the fan and the heatsink.
The new Deep Cool Fiend Shark is compatible with all contemporary processors and is installed with a backplate on all mainboards except for the LGA1366:
As for the LGA1366 installation, instead of a backplate you will have to use rubberized screw-nuts with pads and threaded bushes that go into them:
These are the retention brackets that you will have to attach to the cooler itself before installation:
After that you place the cooler on top of the CPU and tighten the spring-screws. The retention provides pretty high pressure hold, although it is somewhat inconvenient to tighten the screws under the horizontal heatsink. You can find more details on the cooler installation in this manual (PDF-file, 1.6 MB).
This is what Deep Cool Fiend Shark looks like when it is installed onto a mainboard:
The distance between the cooelr base and the lowest heatsink fin is 55 mm.
It turned out that the cooling efficiency of Fiend Shark doesn’t depend on the way it is installed, and it looks very catchy inside the system case:
Now let’s compare the coolers technical specifications side by side and move on to the actual tests.
