For consistancy of results, temperature control & time are as important for B&W as with colour. B&W has the advantage (except for C41 chromogenic) that processing can be carried out at room temperature where the processing solutions will not vary much during the time taken to process a film, so temperature control baths are not really necessary providing room temperature is within a degree or two of the chosen processing temperature. I always used to process at 20C.
