I bought a brand new ML120L (from Amazon) and installed as per the instructions. It does not seem to working properly. Looking for some troubleshooting help. The ML120L started up fine. All lights worked. Fan started, etc. From boot up, my CPU temp would climb steady, even at idle, to 105°C! with the ML120L installed. I have since reinstalled the stock heat sink, the CPU temps have now stabilized under 50°C. Same thermal paste used to install the ML120L, and then reinstalling the stock heat sink.
Stock Heat Sink before = 50°C
ML120L = 105°C!
Stock Heat Sink reinstalled = 50°C
Intel i5-3750K @ 3.4 GHz (not overclocked, was planning too with installation of ML120L)
