Oh come on, at least attempt to get the analogy accurate. Oil is a consumable; there are no consumables with a GPU only component parts.
If you want to try the car analogy then imagine the door squeaked every time you opened or closed it, so you decided to fit your own hinge. 6 months later you try to claim for a new door via warranty because the door you have just fell off.
Good luck with that.
Yea mine wasn't a great analogy. But neither is yours.
Your trying to claim for warranty on the part you replaced.
In GPU terms that would be trying to claim for the Thermal pads you had already swapped out.
More accurate maybe would be fitting a different air filter in your car, and claiming for gear box issue.
And my point here is to highlight in the case of the car, the manufacture would need to show that your change lead to the failure.
So if you changed the pads, and then the memory failed. Well, they can show that to be the case.
The big difference of course with cars and electrical components is where the actual cost is. For example an engine parts cost is going to largely stem from materials and parts. Little R&D.
In a GPU... the actual circuit board and chips dont cost anywhere near the cost of the card to produce. Thats loaded more towards the R&D needed to make it.
As such, replacing a faulty GPU does not cost nVidia anywhere near its RRP. Especially as they will likely refrub the failed cards for the next RMA.
Either way... my analogy is bad. But I am trying to highlight how willing people seem to be to take a manufactures word as gospel when it comes to electronics. Something they would not accept for other goods.
