![]() The dot keeps jumping back onto auto.Ģ/ I have replaced the thermal paste, it's the first thing I did. The fan tests itself at boot, then is either off at room temperature to turn on later, or on to begin with, but at a single speed.ġ/ TPFancontrol is a very cheap type software and would not run on manual. TPFanatic wrote:I have found that without TPFancontrol installed, Thinkpads do not increase the fan speed at extreme temperatures. I don't know if the Nvidia chip on T410 uses paste as well or some transfer pad, you'll find out if it needs new paste in the same procedure as with the CPU. Then take apart your laptop and take off the heatsink, remove the dried up Lenovopaste and apply a "ricegrain" amount of good thermal paste to the CPU. To solve this you'd first need replacement thermal paste. I know on 2008 laptops Lenovo used cheap paste that is well dried by now. Your Thinkpad overheats simply by the CPU working despite fan usage, I think this indicates improper thermal transfer between the CPU and the heatsink. You can set it to run off at idle and run as fast as possible. TPFancontrol is a program that allows you to set the Thinkpad's fan speeds at different temperature levels. The fan tests itself at boot, then is either off at room temperature to turn on later, or on to begin with, but at a single speed. ![]() I have found that without TPFancontrol installed, Thinkpads do not increase the fan speed at extreme temperatures. The cooling system IS working however not the way it is supposed to or is it? (this is my first thinkpad) However, the fan still should have speeded up when temperature would have raised. I am under Win7 and the over-processing problem was caused by wuauserv and is now fixed. meaning that the fins are rotating around the axis, at that speed (RPM means rounds per minute) I had visual confirmation. The thermal paste could be dry or the contact between the heat sink and the cpu could be bad or the fan isn't running at all. Sounds like the cooling system isn't working. You wrote the 'temperature rises dramatically'. Is your fan running or not? If so, at how many rmp's? Have you intentionally written this as a riddle? this one stays silent.Ĭonstant speed.never above 4500 rpm.stays silent. On nay other laptop you would hear the fan speeding up sometimes. ![]() I have noticed that the fan runs at a constant speed no matter what power plan and never goes above 4500RPM. It seems like when the CPU is working hard, the temperature rises dramatically causing the system to shut down. I have a T410 i7 2.67Ghz with Nvidia graphics. ![]()
