Re: X220 - fan constantly on / revving up and down

The turboboost+  is disabled.  I think I've spent several hours playing around with the power manager.

Re: X220 - fan constantly on / revving up and down

Many of us with the fan issue already have bios 1.11.

 

TPfancontrol seems to fix the problem... I wish Lenovo would give us an offical solution to the problem, though.

No, you don't need to disable the Power Manager but I advise not to download tpfancontrol, because all it does is tell the fan not to work until the CPU gets relatively hot. The default fan profile is designed for T61, an older laptop that had higher temperature thresholds.

 

Basically for X220 it's a bandaid that tells the computer to not turn the fan on until temperaute reaches X degrees, but X by default happens to be a little on the warm side for the CPUs in X220. You could achieve the same thing by simply taking the fan out of the computer :smileytongue: (ok, ok, not exactly. Don't do that!) but that's not a very good solution


It can still be effective if you want to modify the profile and set custom triggers depending on the temperature, but I'll leave the instructions to that for someone else, if they want.

But regardless, we should not need to use a third party utility to solve Lenovo's mistake

Re: X220 - fan constantly on / revving up and down

thanks

, is lenovo aware of the fan problem ?

and so not, how can they be reached so that they now many x220 units (and owners) suffer form the problem ?

 

x220 Ci5, no fan of the fan-problem

Yes, they're aware and said engineers are trying to fix it

Re: X220 - fan constantly on / revving up and down

While the TPfancontrol may have a poor profile, I'll note that the sandy bridge chips can run at a much hotter temp than the older chips.  I was watching tpfancontrol to monitor my cpu temps... never went beyond 50c, which is like nothing for these sandy bridge chips.

 

I only use the TPfancontrol when im on battery, using the lowest cpu setting. When i get back to my desk, where i care less about noise, i disable it.

 

IF you don't understand what tpfancontrol does, or what it could do to your cpu (the max temp for htese chips I believe are 100c), then i also don't recommend that you use it.

yes, just open tpfancontrol_ini.exe
