ASA overhangs

I'm having trouble printing bed arms in ASA. I'm running the "latest" RatRig toolhead with Orbiter 2 5 and can get my chamber up to 45C (so far) and overhangs appear terrible in an otherwise flawless print. Fans are at stock RR Generic Orca ASA speeds, any more and the whole thing warps. I tried bringing nozzle and bed temps down to 250/100, with little improvement
