Aeroflow P4

The kind folks at Vantec were nice enough to send a sample of their latest heatsink, the Vantec Aeroflow 2 (P4) (model # VP4-7245) and Vantec Aeroflow 2 (Socket A/370) (model # VA4-7245). This is an update of the Vantec Aeroflow. The Aeroflow 2 is a sawed aluminum heatsink with a copper plug insert which sits on the CPU core. The base

clearly show the copper plug and fin structure, which is different from the first Aeroflow; this version does not feature “unique, four-sided aluminum fins that slope inside the heatsink”, but rather a more traditional straight-cut design.

The grill on top of the heatsink is plastic – on one sample, it was broken:

Cover

It wasn’t immediately obvious until I powered up – then the fan made a racket as it hit the cover. Easy enough to fix – just lift the cover a bit until it clears the fan’s blades.

THE TEST

The Vantec Aeroflow 2 (P4) was tested on an Acorp 4S845A motherboard with a modified P4 1500 to read CPU case temps; for Socket A, I used the CPU Die Simulator.
