Today, I connected (actually my kid did it) the original thermal sensor (keeping the OWC drive thermal connected also) and the fans went back to normal. So that was it.
CPU clock speed still reported at 700Mhz but everything working at a very acceptable response rate, like browsing, watching YouTube and using MS OFFICE. Not thinking of doing any heavy photoshop type of stuff
Is it as responsive as 2024 machine? Certainly not but works as good as a 2017 one, there are some glitches on the screen as some time parts of it are not refreshed properly but it’s a non issue
I have the same question regarding memory but haven’t got my hands around 4Gb simms.
