We shall present some preliminary results of a search of X-ray counterparts (observed by RHESSI and GOES) at the onset or enhancements of radio noise storms observed with the Nancay Radioheliograph. We shall investigate on a few events whether X-ray flare like signatures are seen in close temporal and spatial association with the appearance of the noise storm.
