The Auras LPT-709 has a 92x25mm fan fastened by means of four soft plastic hangers with rubber inserts.
This fastening mechanism prevents vibration and noise level although few manufacturers use it.
The speed of the fan is regulated automatically by means of the mainboard’s PWM feature like with the two previous models.
The Auras LPT-709 (with the Auras AS9225MMF_XB fan model) is specified to have a variable speed of 800 to 2400rpm at a max airflow of 47CMF and 23dBA of noise. The fan has two ball bearings and blue highlighting. It doesn’t rattle as the two previous coolers do.
The heat pipes are flattened in the base and secured with a metallic bar from above.
It’s hard to tell how the contact between the heat pipes and the copper base is established because I could find no trace of solder or thermal glue.
After removing the film from the cooler’s base you can see its splendid finish:
To be absolutely exact, there are micro-cavities in the surface of the cooler base, which must have formed when the copper was being coated with nickel. But I think this negligible defect is going to be corrected by the thermal interface easily. The base is ideally flat.
The cooler is mounted on mainboards just as the Auras SLC-747. You take four screws and secure the appropriate fastener type on the mainboard and then either hitch the cooler to the plastic retention frame around the socket (for Socket 754/939/940/AM2) or insert the locks into the mainboard’s mounting holes (LGA775). Again, don’t forget to remove the protective film from the base and apply thermal grease.
The bottom rib of the heatsink and the fan are 50mm above the mainboard surface, so nothing should prevent you from installing the Auras LPT-709 on your mainboard. The cooler is actually very compact inside a system case:
Its recommended price is $40. We’ll see shortly if the product is worth the money.
