I imagine that if the issue with the iSight camera was resolved that we would also resolve the problem with the fan control, however, there is no definitive answer and my eyesight is just not up to the micro-soldering that is required for a logic board repair, neither do I have the correct equipment to complete such a task. There seems to be a data line that has some link to the fan control that goes to the iSight camera connector on the logic board, now I know that this is faulty, the MacBook doesn’t even register a camera and this couldn’t be resolved by the seller on eBay although it looks like an attempt to reflow the solder around the connector has been attempted, the other circuit that is connected on this data line is the ambient light which is reading 100% within iStat Menus. So for anyone interested here is what I have managed to find out regarding the issue of the fan returning no RPM and not ramping up from the default RPM with an increase of temperature. ![]() ![]() I am unsure as to what could be causing the issue and have combed through google trying to find a similar problem but all the fan issues seem to be with the fan running at full RPM. The problem arises when you try to tax the CPU as the fan is just not moving fast enough to cool the CPU effectively and the system isn’t ramping the fan speed up on a temperature increase. I am unable to manually control the fan speed with iStat, I have tired SMC Fan Control, MAC Fan Control and they are all the same. I configured iStat Menu’s 5.1 and saw that the system fan was running at 0 RPM which I thought was odd, the temperature was also around 55-60☌ which I thought was normal for idle, I turned the MacBook off and removed the bottom to see if the fan was turning and upon starting the laptop the fan burst into life, however, iStat Menu was still showing 0 RPM. I received the MacBook and booted it up everything seemed fine so I shut it down and began work on the screen to remove the anti-glare with Listerine which worked a treat and the screen now looks fantastic if a little reflective I am wondering if someone can help me, I have recently purchased a mid 2014 MacBook Pro from eBay for £300, the seller listed the item as refurbished following liquid damage, the MacBook was sold as fully functional with only one fault, the iSight camera didn’t work and cosmetically the screen had suffered from the staingate issue.
