In the past i replaced the transistor with some irf mosfet .they were powerfull but didnt work properly .now i know you have to put low voltage and hi amps mos.

Hi,
If bias voltage does not match close enough heavier one won't function
properly. Is there a way to improve cooling by heat sinking or applying
proper thermal paste?
