Retail P3 Heatsink vs Gorb

[Travis]

I recently purchased a Gorb and a retail p3 733. I have the 733 overclocked to 957. I was suprised to observe the retail fan/heatsink kept my cpu cooler by about 5 degrees under full load (95f vs 90f). Has anyone else noticed this with there rigs? I am sure the Gorb is mounted correctly and I used heatsink compound. This is very disappointing because in most cases retail heatsinks are not very good. This really makes the Gorb look bad. I also have a Celeron 366 overclocked to 550 with a older GlobalWin fan/heatsink combo that is noticably better than its retail counterpart. Is the Gorb all flash?
