AMD just wants overclockers' money

Why the outcry on warranties being voided with using thermal paste? If you want the three year warranty you have to use the supplied heatsink, thermal interface and all. If you use anything else it removes the assurance that your thermal solution will work. It really isn't that much worse since the interface melts into the processor and makes good contact too. BUT, it only works once, which sucks. I also out of 20+ installs/moves of AMD processors I never once broke a core, even with Thermaltake orbs.
Some also bitch at high wattage output of the Opteron. First of all, the heat dissipation is not even published. Ace's Hardware estimates it at around 52.5w. Not too good you might say, but keep in mind it also has a built in memory controller as well. Intel and nVidia don't have copper (Leadtek) or large surface aluminum heatsink/fan combos on the northbridges for decoration; they put out a lot of heat too. Part of that heat went to the processor.
