Since yesterday I own a U450p and I really like, apart from on thing: the fan is constantly running! The casing does not feel hot at all and the air coming out also isn't that hot. I installed "Core Temp" and it states a CPU temperature of 35-41°C. It looks like the fan goes on/off at 35°C, which is very very low - turning the fan on at >50°C and turning it off at <35°C would make a lot more sense. I already read a lot about fan problems in the forum, but does anybody know a solution for the U450p right away? I would be really thankful.
Solved! Go to Solution.

hi xloserx, thanks for answering. I tried to follow your instructions step by step:
- install NHC
- download & run NHCConfig
- download U350.txt
- open U350.txt and replace all U350 with S10e
- rename file to S10e.cs and put it in the NHC folder, replacing the S10e generated by NHCConfig
- now start NHC
but it doesn't work. I'll call Lenovo tomorrow and ask what to do about it. If Core Temp reads the correct temperature, the fan is turned off below 35°C only, that's too low

Ok, today I called and the hotline confirmed that 35°C is too low and that should be fixed. So now I'll have to decide whether I keep the laptop and hope for a BIOS or whatever update or if I return the laptop to the store.
In the support / driver download section there are no drivers at all available for the 3389-L5G so far.
With NHC I still had no luck and no time to try out everything, hopefully next weekend I have some more time.

I'd be happy to hear whether I am the only one with that problem, because if I am, I would have to send it in but if I'm not, I'll wait for a new BIOS with corrected temperatures.

same probleme here. i have my lenovo u450p since one week and it appears to have the same problem.
fan turns off and an at around 35/36 celsius, as you said.
actually it is a really nice notebook but that issue is a kind of annoying. the cpu temperature is constantly around 35 celsius. thus the fan turns off and on constantly.
i also hope for a new bios, or some other software which could fix the problem
