This is to hot for stock temps, your only supposed to use a pea sized amount of AS5. The AS5 website uses way to much AS5, they want to sell as much AS5 as they can, so sure there going to tell you to huge amounts. Remember your only filling the microscopic vallys, use to much AS5 can cause the heat to build-up rather than the transfer of the heat.
Filling the microscopic vallys doesn't require that much AS5, use a pea sized amount and spread it from the center (I used my finger) of the CPU out to the edges. Tighten the TT 120 screws to 80-90% tight because to more pressure you have on the CPU the better the heat transfer. My TT 120 screws are 90% tight and at stock temps for my E6600 idle is 18c with 27c load.
