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.
It is necessary to put any thermal pads back and reapply thermal paste to places where the thermal paste was disturbed. Thermal paste needs a good seal without air bubbles. you also do need to clean off the old thermal paste before reapplying How to Apply Thermal Paste first thing said in the guide: {caution sign} Thermal paste is responsible for conducting heat from the processor to the heat sink. Reassembling a computer without applying thermal paste will cause the processor to overheat, resulting in permanent damage.
Hi Enrique, Have you replaced the thermal paste? did it help? I have a mid2010 27" that is also hot on the back and on the screen. I’ve already opened and cleaned it out but am thinking on getting an SSD and wondering if it’s a good idea to replace the thermal paste and whether it would help or not. Thank you!
