Aerocool Extreme Socket 478 HSF Review


Closer Look
Like most other heatsinks, the unit is essentially an 80mm fan on top of a copper heatsink. In the 2 photos below, the fins appear to be pre-sliced and then attached to the base of the copper block (hence the name, "Bonding Fin"). Whether or not this actually results in a detrimental cooling effect remains to be seen.

The bottom of the heatsink has have a safety sticker at the bottom. While the pre-lapped surface is not a mirror finish like that of the Volcano 7+, it should be more than sufficient for the task. If it becomes necessary, the heatsink can be further lapped in order to achieve that polished look.

With so many heatsinks that follow the method of "fan on copper", the only real determinant to these heatsinks is the manufacturers' various methods of getting the heat up to the fins, where the fan can exhaust them. Using this premise, this heatsink is expected to perform with results that are similar to other heatsinks that utilize this method. If there is a fan controller available, then it should be similar to the cooling performance gained with the fan at medium setting.

Since I am testing this on an Intel system, some adjustments were required, mainly the removal of the AMD clip and the installation of the P4 clips. What really bothered me, is the actual installation of the heatsink. The next photo contains an excerpt of the installation instructions.

Basically, the heatsink is to be placed on top of the CPU, and then the fan (with the clips attached) will be installed on top. The clips are then pressed into the hooks of the retention module. However, the heatsink is significantly smaller than the dimensions of the retention module, and there is no spot in particular where the heatsink would not freely slide over the CPU's thermal-pasted surface. This means the only thing holding the heatsink in place is from the force of the P4 clips when they are installed into the retention hooks. I've tried rotating the heatsink 90 degrees, to see if the other 2 sides would somehow securely fit into parts of the retention module, but to no avail.

On its own this is not too pressing of an issue, especially if the computer is not moved alot. However, if you're an individual who loves to carry his rig to LAN parties or whatnot, be extremely careful subjecting the heatsink to too many road bumps if the tower is held vertically. The clips themselves are quite easy to move, and this suggests that there is not alot of force from the clips to hold the heatsink down.
