That is very funny. Mine throttle always at 0.8 after 5minutes of HD video editing. I did the same as you on my laptop (GRIZZLY THERMAL, undervolted etc) but never found a way around it (except disable the inter thermal framework drivers for good) I tried to explain this to the customer support, fought for it for a long time but never got it right even though I had a professional customer service plan. So my only solution was and is still todayto go through mac OS with this laptop.
If I were you, I'd order a new heat-sink assembly. There is a beefier aftermarket version that is better than stock dell. I suspect the factory/you may have bent the assembly on installation/de-installation. Even stock 0.8Ghz throttling was never observed on my machine and I live in Queensland Australia which is often is as hot as balls. I heavily suspect that the silicon is not making proper contact with the heat-sink
