If the hotest it ever gets is 150F then you're OK. That's about 65C, which will certainly feel hot to the touch, but enough below the 85C where I'd be worried. Can I assume you have a think layer of thermal paste between the FET and the heatsink ? If not then do this, it will help. The datasheet for the FET should have some curves for max current vs case temp.
