Do I need to replace the thermal paste?
I'm opening my iMac to install an SSD. Since i'm opening it already, I thought, what else can get better here ?
So, should I replace the thermal paste/pads ? The CPU is currently at 57ºC, idle, and the fans are running at 1400 RPM (room temperature is about 28ºC) . Of course the back of the iMac is hot, as expected, but the screen is hot too. I don't know if that's expected to happen.
In the case of a replacement, what should I use ? I've heard of K4 and K5. Why those and are they really necessary? Are pads better? What about Arcticlean remover ?
Thank you in advance.
