Fans louder after thermal paste job, despite a lower temp.
crwdns2934249:0crwdne2934249:0:
I just replaced the thermal compound of my old MacBook Pro (high quality grease, the old one was dry as dirt).
Before that, I had to underclock it from 2 to 1GHz to keep it stable (using Coolbook). The temperature at rest was around 55°C, and at full CPU load, it would reach 72 °C. The fan never kicked in at that temperature (never loud, but I didn't measure the speed at that point), but if it stayed that high for too long, the machine would freeze.
After the paste job, at 1GHz, even under load , the CPU temperatures (Core1, Core2 and CPU temperature diode) don't exceed 53°C. However, in these conditions, the fan runs at 3800 RPM (louder than what I remember it was before).
If I increase the clock speed, the fans accelerate, and reach 6000 RPM under load at 1.5 GHz. The temperature is then around 65-70°C
I measure the temperatures using Marcel Bresink's Temperature Monitor and the fan speeds with Lobotomo Fan Control. The latter is supposed to enable tweaking the fan speed settings, but it doesn't work here.
I also noticed that the temperature is now more volatile than it used to be.
Thanks in advance for your help.
