The sound output created by the 112BJO is quite low. This is mainly due by the fact it does not employ the all too common 6800RPM Delta fan - which while improving CFM's, generates a lot of extra noise in the computer system.

Synthetic Temperature Test Results:

The move towards all copper heatsinks has taken much of the steam out of what the all-aluminum heatsinks can rightfully handle. The AVC 112BJO manages to maintain a temperature under the all important 60-degree mark, but it is by no means a performance heatsink. At best it is an average performing OEM class heatsink - good for those home systems which can survive on a regular heatsink.

Interestingly, the AVC 112BJO uses the same type of fan as the Coolermaster DP5-6H11 does. The two heatsinks are similar in size and shape and have an equally close ranking.

In the end, the AVC 112BJO reinforces our original impressions. It is a very good OEM class heatsink, but lacks the muscle needed for performance cooling. Good for a moderately powered system, the 112BJO should cope well.

Apart from the thermal implications have the thin-fin 2mm spacing, the AVC heatsink has all around good quality to show for itself. Seeing as the base is not machined flat, it was not surprising to see that the surface is slightly bowed out. Practically every extruded heatsink we have ever looked at has had either a bowed or a cupped base. The degree can vary from one heatsink to another, but in general they angles are very slight and barely visible.

For the purists out there, it is always a beneficial idea to lap an extruded heatsink which has not had machining on its base to try and achieve a flatter profile. The lapping also helps remove minor scratches that may exist on the base of the heatsink, either from the extrusion process, or from brushing of the base.
