Like in any other cooler with heat pipe technology, the area of contact between the aluminum ribs and the copper pipes is enlarged by means of bottlenecks that formed when the ribs were being put on the pipes.

By the way, the aluminum of the ribs is very soft and bends easily.

The fan of the Auras SLC-747 is made by Yen Sun Tech and runs on two sleeve bearings.

The fan supporting the PWM regulation feature, its speed can be varied from 700 to 2400rpm at a max airflow of 47CFM. The manufacturer specifies a noise level of 23dBA, but does not mention at which rotation speed it was measured – the value doesn’t seem correct for the maximum 2400rpm. The fan motor also rattles rather irritatingly across all the rotation speeds.

The cooler’s base has a piece of polyethylene film to protect it against scratches.

I can’t say the cooler’s base is finished well: the traces of the milling machine are visible and perceptible by touch.

Those who like it tidy have got some work to do here. Anyway, the uniform trace of thermal grease on glass testified to the flatness of the copper base.

You hardly have to look into the manual to install the cooler on any platform it supports. It’s all simple and intuitive. You secure the appropriate fastener with four screws and hitch the cooler to the plastic socket frame (for Socket 754/939/940/AM2) or push it into the mounting holes on the mainboard (for LGA775). Don’t forget to remove the protective piece of film from the cooler’s base and apply some thermal grease on it beforehand.

Inside a system case the Auras SLC-747 looks like follows:

Although the cooler is compact, I found it could only be installed on my ASUS P5K Deluxe mainboard in one position as shown in the photos. Otherwise, either the tall heatsinks on the MOSFETs around the socket or the chipset heatsink would get in the way of the cooler’s pipes. On the other hand, it is not exclusively the cooler’s fault because there are few mainboards that have as many heatsinks and heat pipes as the ASUS P5K Deluxe. Moreover, the orientation of a cooler like Auras SLC-747 inside the system case is not as important as with tower-like coolers.

The recommended price of the Auras SLC-747 is $31.5 which seems to be the main drawback of this product. I think this price is overstated by about 35%. Running a little ahead, I should confess you can spend this money to buy not only a more efficient, but also a quieter, cooler.
