This isn't about an error; but more complaint of airspace or VFR procedures. Because this event left me shaky and barely able to talk to give pilot frequency for next controller. Aircraft X was released on a 31L CHISM3 SID off HIO. I was watching a decently fast primary going through the airspace for a bit. It went into the lateral boundaries of HIO so I called to see if they were talking to them to see if inside their airspace and they giving traffic. They said no; no one there inside their airspace. Aircraft X finally tagged up couple miles north of it in their turn and by the time they checked on there was nothing I could do to avoid the target so I told the pilot; just in case maintain 3000 because HIO is about 2700 and they said they don't see it. After hearing there was traffic there and maybe concern with how I said it; the pilot slowed their normally very fast climb off HIO and moments later told me traffic in sight; passed just above us; good call. I could barely talk to send to Hood for higher. I have not been that shaken like that for a long time. Something unknown could have been a disaster if I didn't trust my uneasy feeling.This later just adds to the fire of VFR pilots not paying attention to their surroundings or ignorant or not caring. Our class Charlie is literally a VFR circus around IFR itinerants. There needs to be some way to force pilots to talk to ATC if anywhere near airports known to have dangerous airspace up to at least the initial departure alt 7000 at PDX; 4000 at HIO; TTD; and UAO.
P80 TRACON Controller reported a fast moving VFR aircraft was observed; traffic was issued; and the IFR pilot advised they saw the aircraft which passed just above them.
