All right, my i7-920 is running at stock, however it is idling at 70-80c and under load 90-95. I'm running the stock heat sink on top of it, there is no dust, it's all very clean and airflow in the case is good running at an ambient/system temperature of 29c - I live along the coast.
However, my the thermal paste on it is old, there is basically nothing left, and my heat sink is touching the CPU well enough since it's rather hot so it's definitely transferring the heat correctly but can be greatly increased with thermal paste. If I apply a paste, will it lower the temperatures significantly? I'm at a loss here, everything seems to be perfect besides the thermal paste which I am going to buy soon hopefully tomorrow or by the latest the day after. Note that I have no performance hits due to these temperatures. Just wondering if I'm overlooking anything here. Will a good thermal paste reduce my temperature significantly?
