imac video card replacement
imac video card replacement
is a very common repair on imacs before 2013. graphics chips used to fail quite often on macbooks, imacs as well as pc, mac minis and all other devices. there are couple reasons for it. some graphic chips were defective, some were good but perhaps were not installed properly, some overheated and their life expectancy has shortened, some just died prematurely.
graphics chip overheating definitely contributes to failure and apple of course is a little responsible for it as well! first of all apple markets their devices as invincible and all super powerful designed for high end graphics processing used by creative people in all kinds of industries. now in reality, macbooks are really not designed for that at all. they might have powerful hardware and some do, but they dont have proper ventilation whatsoever. imacs are a little better but just as bad. they are all in one computers and they dont really have proper ventilation either, which is necessary for any graphics chip that will be overloaded to max capacity to process data, which makes it heat up to the max. as result they will have shorter life span and will fail and imac video card replacement will be needed.
another thing that apple is doing to their macbooks and imacs and their customer that not a lot of people know. is that they use cheap thermal paste to create heat continuity from the chip to the heat sink. the cheap thermal paste is not so good after all and it prevents heat sink and fan from doing its job properly also. if better paste applied some people recorded temperature drops at around 15 degrees lower than with bad paste that apple uses.
knowing apple, this maybe intentional. cs if your imac video card fails and you need imac video card replacement they will quote you a price that is not cheap and you will start thinking about buying a new imac. And their sales people will also steer you in that same direction. anyhow. who knows whats going on there. im just giving you direct info from whats going on in mac repair world!
anyhow, this 20 inch imac was not booting up. and after few tests and other component tests we quickly determined it was graphics chip failure. since this was an older imac it was actually cheaper to replace video card with new video card and problem was solved. if you have 2011 or 2012 imac 27 inch it is usuallly cheaper to get graphics chip replaced!
