if we look at the test results for the Alpha PAL-8150 heatsink on the synthetic temperature test platform, it is pretty clear that this socket 939/940/754 heatsink performs very well under a 125W heat load. Its resultant rise above ambient temperature of 23.7°C spotlights the Alpha PAL-8150 heatsink as a thermal solution that can handle the task of cooling current AMD Athlon64/FX/X2 processors with grace.
Because cool air is drawn in at the base of the aluminum pin fins, warmed by the transfer of heat energy and then exhausted at the top of the heatsink, a couple of things are assumed. First of all, there should be sufficient space around the sides of the PAL-8150 heatsink so the intake of cool air into the forrest of black anodized aluminum pins is not impeded. Secondly, there should be enough head room above the heatsink for that hot exhaust air to exit without undue flow resistance. A desktop case with side panel venting, or a side case fan set to exhaust air out of the chassis would be ideal.
With sound measurements in the 59 dBA range, the Alpha PAL-8150 heatsink certainly doesn't earn marks for reduced noise levels. Instead, this Alpha heatsink can be looked upon as a performance oriented K8 cooling solution with abundant cooling capacity for the latest and greatest dual and single core AMD Athlon/Opteron processors.
