2012 MacBook Pro Fans no longer increase in speed?
Hello,
I recently installed a new third-party battery and replaced my HDD with a Samsung Evo SSD. Everything has been running amazingly, battery life has been great, the speed of my MacBook is so much quicker it has become a joy to use again.
But, just recently, as usual when converting video formats, I have noticed the base of my laptop getting very very hot. Usually I’d notice that the fans would ramp up to combat this but since replacing the battery and SSD I haven’t heard the fans increase. I downloaded “Temperature Gauge Pro”. All the sensors appear to be giving a reading and the temperature increases when the machine is used. It says the fans are running at approx. 2000rpm. I‘ve adjusted the settings on “Temperature Gauge Pro” so the fan increases its speed when the CPU Core 2 reaches a certain temp and that works just fine, but when I change it back to its default settings the fan drops to approx. 2000rpm.
I have run the hardware test and the only fault it comes up with is 4BAT/6/40000005: 0x8983e990 which, after doing some research, could be caused by the fact I have used a 3rd party battery.
I was curious as to what the default temperature sensor is set to sense? If it is set to sense the HDD, now I have replaced it with the SSD that has no moving parts and never gets above approx. 35°C, could this be the issue?
I am still running OS X Mavericks and am reluctant to upgrade, could this be the problem?
Can anyone help me and possibly suggest a remedy, it would be greatly appreciated?
Thanks
Matt

Hi Dan, thanks for the advice. I have downloaded Coconut Battery and the link below is a picture of the information from the App:

I have also attached a screen shot of the trial version of TG Pro:

My last battery didn't work at all, hence why I installed a new one, so there is no way I can swap them back to see of this was the problem.

And here is a screen shot of Macs Fan Control:
Is this a good question?

I tend not to use fan control software as people misuse it and in doing so damage there system! Apple does do a good job with their cooling. The problem is we the used want more from a laptop than what it was designed to do! Think of it this way you can drive a racehorse to the point of death on a race track as it doesn't know any better. We're doing the same with our laptops when we run heavy work loads they just weren't designed to run. The speed of change within apps is quite amazing. Each generation needs more compute power than the last and some of the things we are doing with our systems what not even envisioned when your system was still on paper.
Thats not to say you can't run something that needs more compute power for a short window of time, its the long sessions like in online game play and even stand alone games as well as video and sound processing thats hard. Going back to our racehorse a high speed sprint is doable unlike a long race.
Newer systems are always in the pipeline and each generation are pushing the limits of the technology and able to run more effectively than the last.
