This is my computer, which I paid for with my money. Plus I have alerts set at certain high temperatures, to warn me if things get heated inside the computer. Really? Are all Apple users that dumb? I have a temp readout on the screen next to the date/ time, and SSD Fan Control icon in the dock. The excuse the company clones use is that I might overheat my processors. Of course this means kernel_task is using 80% of my cpu time constantly, but hey! I paid £1500 for my MacBook why shouldn’t I suffer by only being able to make use of 20% of its capacity? I also have Temperature Gauge 4.1 running on my MacBook Pro and that tells me that the CPU runs at around 50C if I pre-set the fans at 2500rpm, whereas the SMC fan temp readout is 128C which is the default Mac setting for a faulty sensor somewhere. Oh, and while smcFanControl will not override the fan settings, the SSD Fan Control app will, and it is free - although you can donate by PayPal (I did because of the sheer relief at the peace and quiet). How do you think they became a $1 trillion company? Given that the motherboards are probably put together by some 12 year old girls in a Chinese sweatshop factory while earning $1 a day, is it surprising that components fail? Is this for real? One tiny little temp sensor goes wrong and the whole board must be replaced? What planet is Apple on? Well I will tell you planet maximise income, that is what and if that means forcing everyone to replace almost the entire contents within the casing once the machine is out of warranty, then so be it. Well well, just look at all these ‘clone’ replies telling you to get down to an Apple Store ASAP, and spend upwards of £500 on a new motherboard just because one sensor is faulty.
