The HR-05 is overkill for a 865PE chipset.
Any of the passive Zalman NB coolers will do, just make sure it'll be compatible with the retention mecanism of your NB cooler.
yes, multiplectic is right, the HR-05 is too much for it. I thought I saw 965 for some reason :S
Anyways, any passive zalman cooling (the orange heatsink or the blue one) are good enough for it.
