I changed my GPU thermal paste 2 days ago. I guess I need to open it again and empty the rest of the tube.

Back in the very early 2000s a friend on mine that I thought was pretty technical heard me talking about thermal paste and he had never used any. After telling him about the benefits he was excited to get some and use it on his new PC he was building. He came in the next day sad, said it had fried and he thinks it was the paste. I asked how much he put on and his response was "umm, like icing on a cake". in my head it was even worse the the posted image.
Oof, it’s nice that most thermal paste these days is non-conductive
The only thing too much thermal paste does is leave a mess, but you might need thermal pads on VRMs for better contact
Too much thermal grease is a barrier to heat, because it should only replace the air (a potent thermal insulator) between uneven surfaces. Oil would be better, but that runs away.
Which is also why you shouldn't smear the grease, because then you get air pockets. Rice corn or spaghetti method displaces the air on putting the cooler on.

I'm not familiar with those methods and "rice corn or spaghetti" makes me think you boil the the paste first
Idk what rice means here, but I can guess corn is just a bead in the center and spaghetti is the same thing but you have a narrower tube so the ball looks like spaghetti.
Rice sounds like it wouldn't be enough paste to cover the die. Like you're just putting down paste in a very small line the size of a grain of rice. That's not gonna spread enough, bruh.
Wouldn't sharing heat from a processor directly with other chips be a bad thing? Always imagined you could fry the little chips by the CPU or GPU or whatever you're cooling
The chips are going to have a similar tolerance to heat. They're all silicon and the fundamentals of how they work are the same. So if may be making a chip hotter than it normally would get, but still within its operational limits it'll still work fine.
Though there is the argument that if the chip otherwise wouldn't get that hot that you're subjecting it to more thermal stress by subjecting it to wider temperature swings than it would otherwise experience. However, I wouldn't worry too much about that as by the time that might be a problem, something else would have given out long before that.
How does someone get to know thermal paste is a requirement without accidentally seeing how it's required?
This is like knowing petrol is needed for your new car, then just stopping at some point, referring to the note "Get petrol" and deciding pumping it into every orifice the car has is what that means. "I assume that's what that meant. I'm in a rush. No time to Google how to pump this "petrol" thing into the car."
I can't remember the video but it was some dude from a major computer YouTube channel fillmed himself building a PC. He used a grounding strap that wasn't grounded and did all this crazy crap. They ended up taking it down fairly quick but not before everyone made fun of it. I think even he used thermal paste though.
It was the verge lol
I saw another video where the famous YouTuber censored out the thermal paste pattern sort of as a joke but sort of genuinely heading off comments disagreeing with how he put it on.
Engine oil? Well, petrol comes from oil! Better fill it up! Air goes in the intake, and we need fuel and air to mix. Throw some in there!
Reminds me of this:
Is it odd that this is not even close to "bad" I have seen? Hell I have seen things shipped from production with this level of glorp.
It's not glue lol.
It's paste. Which means it's edible. 😌
Oops all thermal paste!
Me when I have to use anti seize in the shop
At that point it’s just thermal paste with slight hints of computer.
The bigger the gob, the better the job!
Loads of goo? I can count on you!
Don't do this
Yeah: Use a paintbrush to cover the whole motherboard instead.
Get a couple cans of spray thermal paste.
Fill up the entire case until it is one big block. The smoke is just the paste settling. And the flames. Also the Fire department. It is settling.
Witness me!
Not sure I see a problem here, this all looks intended. I'm not familiar with this device though. Since the heat sink plates are so big and the screws are so far apart I'm not sure they could get away with less without potentially missing contact with a sink. It seems more like bad mechanical engineering than bad application.
Thermal compound has a thermal resistance. It's better than air, but not as good as metal. The best application is a layer that fills all the air gaps, and no more.

“A dab’ll do ya.”
if they had to put some in their mouth, they should have used mayo instead.
They mayo goes in the computer and I'd like a ham and cheese on rye with extra thermal paste.
