Temperature sensor detached, fans at 6000 RPM. Advice?
My MBP 15" recently suffered a GPU failure. I managed to reflow the chip but accidentally tore off one of the temp. sensors (the one closest to the left fan, IIRC). Fan Control app reads -128 degrees C and the fans run on 6000 RMP constantly. iStat reports normal readings (Airport, CPU, GPU etc.).
I'm assuming the fan malarkey is caused by the detached sensor. Correct?
If so, is there a software that allows me to limit the fan speed? iStat and fan control only allow you to adjust the base/min speeds.
I fear my only option is to re-solder the teeny tiny connector back to the motherboard. Hopefully you guys and gals can provide some other solution to my problem!
EDIT: Conclusion: The temp. sensor fault indeed causes the fans to go full speed. I have to try to solder the broken connector back or take the laptop to someone who can.
SMT components are very delicate! As well as the SMT connectors. You'll need to find someone with the correct tools and skills to reconnect the connector.
Not easy! I did the same thing too on one of my first reflow attempts. I ended up getting a new logic board for the customer.
