The heatpipe cooling is perfectly fine. You don't have to worry about the NB/MOSFETs heating up unless:

1) Your casing ventilation sucks
2) You are going to overclock alot

In either case you should:

1) Get more fans/change your casing
2) Place fans on the heatpipe radiators
3) Replace with a better chipset HSF (JingTing, HR-05, etc)
