I'm revisiting S04, as I had it down that I didn't like it, but I've realised I only ever used it in kits so I'm giving it an outing in an all grain brew. I'm fermenting at 17.5° c. It's sinking my garage / state of the art brewing facility out like a blocked drain. I've had this before, and it always turns out ok, so I'm not unduly worried, but is it normally this pongy? Unfortunately, my record keeping when doing kits was pantaloons, so I can't refer back - I certainly had a few stinkers, but can't say which yeasts.
