Fan running at 6500 RPM after logic board repair

After spilling liquid in my computer about 6 months ago, I decided to fix it in a tech store. They told me, I had a few components broken, so apparently they fixed the logic board. After a few days of the computer working perfectly, the fan started running loud again, at 6500 rpm. The only difference with what happened before, is that my computer is not running that slow, just a little bit, but the sound it makes is really annoying. Does anyone know, or have a clue of what can be happening?

Thanks.

Either one or more thermal sensors on the logic board have been liquid damaged and need to be replaced or instead it could be the trackpad thermal sensor gone bad, if unplugging the trackpad stops the fan from spinning high rpm then the trackpad has to be replaced.

Give this app a try: TG Pro it will allow you to see what sensor is failing.

Thanks for the answer, I have the TG PRO, all temperatures are ok, the only thing that its a little bit strange is that "PECI system agent" temperature, appears and disappears. The sensor diagnostics is yellow, and says that maybe de GPU sensor if failing. Any other clue?

PD: I have warranty over the reparation, the problem is that is on Spain, and I am currently abroad. So, maybe if someone know what can be happening can be really helpful.

Thanks

Sounds like you still have a logic board issue from the liquid spill. You'll need to ship it back home to get it serviced by the person that fixed it before. Sorry nothing you can do here on the road.
