What you need beyond a normal solder iron, solder and flux is a stand with a good light, a magnifying glass, some means of holding the board steady, and a solder tip with a sharp point. (Which would be made easier if you can identify somehow who the manufacturer is and what the part number is.)Īnother possibility is to get a board that's failed for some other reason, and cannibalise it.Īs far as soldering, SMT soldering gear is affordable. (Not every device has dozens of tiny pins.)Īs I don't know where all the other sensors are, I can't say whether they're integrated into a component (like the SATA cable) or whether they're stand-alone components.Įither way, Apple would have purchased the sensors from someone, so getting a replacement will be a matter of finding a supplier from whom you can make a purchase. In spite of what Matt says, where he is essentially paraphrasing what the industry wants you to believe, once you find the component, it is quite possible to replace it, even when its a SMT device. So I went and bought some heat transfer compound, and will do the CPU/GPU heat-sink when I get some info about the other sensors.

Their delivery was good, but replacement of the cable, in my case, didn't fix my problem. Their diagnosis didn't sway me either way (since they just wanted to replace sub-assemblies for $$$), and so I decided to order the cable and see. I was sceptical and decided to take mine to Mac Doctors first.

They suggested I change the hdd SATA cable since it wears from heat over time. So, whilst trying find more info about this, I came across and posted there. However, what was encouraging was the throttle problem was intermittent. I don't think it suffered water damage but rather shock damage.Īfter replacing the hdd with an ssd, and replacing the broken glass, the only remaining problem was that the CPU was being throttled, presumably due to a heat problem. I have a similar problem/symptom on my MacBook Pro 13'. I know there is one in the SATA cable that goes to the hdd, and I know there is one on the heat-sink.

I would really appreciate an annotated photo if someone can put one together. There are a number of sensors (6 or 7 I think), but I don't know where they are all located.
