Modifying fan controller for E6400/E6500

[ronan_zj]

I have a E6500 with nVidia docked with two monitors connected. The fan would be on all the time at about 3K - 3.5K.

I have downloaded the I8kfanGUI 3.1. I set the "Main operating mode" to "Automatic temperature control".

Under Options->Temperature Control I set:
Enabled Enable CPU temperature control
Enable first fane
35 - 20 = slow
45 - 35 = slow
55 - 45 = fast
65 - 55 = fast

Under Options->Display Options->Sensor updates
Internal sensor reading: 1 second
Fan setting enforcement: 10msec
Hard drive temp reading: 1 min.

My system now runs the fan at about 2.5K and is silent. Sometimes it goes up and immediately down. The BIOS tries to kick it into high every 3 seconds or so, but the software brings it down.

I am running usually between 40 and 45C for the CPU and 50 - 60 for the GPU. The difference in noise made it possible to use it without headphones.

I use it for MS Office, Web, Visual Studio Dev, etc. I don't play games on it.

can we set the fan runs constant around 1500rpm?
