Volume fire is too bright

I have exported fire+smoke vdb volume from Houdini and I try to render it in C4DtoA. Looks nice but problem is too bright fire. I use temperature channel and when Kelvin value is 200, I get nice brightness in area where fire starts. I have to push Kelvin to 3000 that I get fire the most far area. At this point 95% from fire is too bright (total white). How I can linearize the temperate channel? Or what is the right way to do it? Or should I adjust it in Houdini already?
