Ok so I was woefully wrong about the clearance in my case for HSF. I have about 110mm at the most from the chip to the base of the power supply.
So those coolers that fowler mentioned are not going to fit.
So after suggestions for lower profile coolers or Something like a H60, H75, H90 etc
At the rear I have a 120mm fan opening and at the top of the case a 140mm case which would fit the H90
So more options please
Thanks
