I too find it worse with thermald on my Macbook pro. With thermald, the frequency clipping is too severe, and fans stay below 50%. I think the fans should still try to increase while cpu frequency clipping is happening by default.
In my case, without thermald, the CPU temp goes about 5--10 deg higher at very high loads, but it still seems fine as the fans quickly kick in. and at worst, cpu frequency clips to prevent extreme temperature.
