The 125W (black editions) should come with better coolers than original phenom ii CPUs, still i think the PII heatsink would cool down the APU more.
Heatpipes usually mean more cooling, the same goes to the amount of metal there is, more metal more cooling.
OK, then I'm good with using the PHII X4 cooler on the FM@ board. I just didn't want to disturb the existing cooler and TIM if this wasn't going to fit the FM2 retention bracket. But if you say the brackets are the same, then I will go for it. Thanks.
