Hi, I have this MacBook White 5,2 with Mountain Lion installed that has an issue using an SSD instead of the regular spinning hard drive. The fan spins up more easily when the SSD is inserted if f.ex I'm watching a YouTube video, a movie trailer or a clip elsewhere on the net. But it's not just that - in general use the fan spin up from it's usual 1996-2000 rpm to about the highest at 6500-6700 rpm more than I personally feel it should, like if Transmission is downloading something then during what I think is the due to the write portion the fan spins up to to its highest during the whole time Transmission is doing writes to the SSD. It could be as simple as copying files within the OS too. During installation of OS X Mountain Lion the fan also spins up to its highest for more than 5 minutes if not 7 or 8 making the install procedure very noisy. I would love to use the Samsung 830 128GB model of SSD I have with this MacBook 5,2 and without using a tool like UltraFan(from this forum) or SMC Fancontrol. What could be the matter? With the SSD inserted in a regular PC there's no issues with fans going up - not that I can hear because the PC I have is very loud in itself. Is it a bad SSD I have gotten myself? It's pretty old now so no returns is possible.
