Your CPU would overheat and burn your PC from the inside, best case scenario your Operating system shuts down your PC before it reaches a damaging temperature.

No, just no. Love your work Nibbles but thermal paste is not cooling anything. The only thing it does is making the contact to the actual coolant (for example copper heatblocks) as gap-free as possible i.e. closing micro-scratches and conduct the heat to the actual coolant as good as possible. Metal is great at conducting heat that is why most modern thermal pastes include metal parts and for enthusiasts there are even liquid metal solutions. But the (optimally) tiny amount of layer between the cpu and the heatblock is not cooling at all. The copper heatblock isn't cooling that much as well, its only conducting the heat to the fins where the fan comes in and cools the component down with cold air. Thermal paste conducts heat but does not cool on its own. Miraculously, toothpaste is pretty damn good at this too. Or ketchup. But don't try this at home. I'll explain later. 56 minutes ago, iJaVaFx said: Is water cooling really worth it ?? Yes, because water takes the heat away from the components much better (much higher conductivity than air) and its usually embedded into the copper heatblock i.e. water flows through the heatblock directly taking away all that nasty heat. Much better than air. But only if you want 5+ GHz, total silence and don't care about the costs. To the original question - why not toothpaste: Because it goes bad pretty quick. Thermal paste is designed to stay semi-liquid and deliver good conductivity for years. But it can go bad too. Toothpaste (and ketchup) will spoil, it will harden too soon and thus create micro-gaps, bubbles, holes and thus loose conductivity very quickly. You can use toothpaste and ketchup but not for long. This reminds me that I need to open my 5 years old laptop soon because the fan is spinning faster and faster lately - the thermal paste is probably too old and needs to be reapplied. Probably gonna open up my PS4 as well... Video testing all of them: Spoiler https://www.youtube.com/watch?v=D-pr4cf70qY Cheers
Mashi Posted May 10, 2019 Posted May 10, 2019 Plain old toothpaste without stripes, sparkles, or flavoring works okay. If it has baking soda in it, that's fine too. If it's got shinies, sparkles, and tastes like oranges? Yeah it's gonna go bad quick. The company I work for puts it in our emergency field repair kits, because sometimes you're going from location to location and you run out of actual paste, or you run out of thermal pads(aka paraffin wax), or it's too cold and other various reasons. Same rules apply, you only need a bit otherwise you're making a blanket. Thermal paste that's worth anything has a cure period. If your paste is still wet a year down the road, it's working as great as a blanket is. The whole point is to eliminate air gaps, pastes that remain pastes really aren't worth anything if you're looking for that 'extreme cooling edge' for overclocking and whatnot. During the set period you want it to move, fill the gaps right, once that happens the curing phase should start and it will effectively 'bake' between the CPU/GPU and the cooler. Good paste usually has silver, copper, aluminum, diamond, carbon or some other material mixed in to increase the thermal transfer. That's why you don't want a wet paste a year down the road. Rather when it's curing you get a whisker or wick like effect between the two surfaces where there is large gaps. It's why you'll see people who heavily overclock do things like lapping the lid, or lapping the cooler base to get as close to a mirror finish with no low or high areas on the cooler. Same reason delidding intel cpu's a few years ago was all the rage. Sure they put a lid on it, to even out the heat and get a larger transfer area. But the paste was always wet, never cured and was just like a wet blanket. And it's why delidding, slapping a small amount of paste on it, and directly putting a cooler against the CPU die would give you 15C or more temperature drops.

Didn't knew toothpaste would also work since I was pretty sure it doesn't contain those needed components, but apparently I was wrong. I knew it dissipates the heat, but couldn't find the right english words for it, IT related stuff gets explained in my own language here in my country with it's own terms which kinda gets confusing every now and then.

In the industry I work in, we don't use normal run of the mill thermal paste, the stuff we do use has to work in environmental conditions outside of a controlled environment like the home, or a white collar work place. Which means it has to do more than just transfer heat. But also act as a waterproofing membrane, and be non-conductive. The application of it, well it doesn't work at all when it's -10C out. Good old tooth paste is still pliable at -25C. It's kinda like going: well I own a diesel but it won't start. It always worked when I lived in the middle of the US and it never got under 5C. What? What do you mean I need glow plugs to heat the air prior to it entering the chamber when it's -30C.
Jansen2 Posted May 13, 2019 Posted May 13, 2019 The logical question still stands though, if you already have a suitable paste to hand which I'd assume you do if you're working in industrial applications in subzero temperatures, why don't you simply carry an additional tube of that instead of toothpaste? In subzero temperatures toothpaste won't necessarily freeze but it will "freeze dry", becoming brittle, powdery pretty quickly. Diamond or even a standard silicon-carbide thermal paste is going to be more efficient I'd have thought. Admittedly I've never been in a situation where I've had to test toothpaste vs thermal compounds in subzero or any temperatures but using toothpaste as a substitute for a thermal compound in any situation seems... well... silly. Like clingfilm in place of a condom. It might well do the job but I wouldn't want to try it on my expensive/sensitive equipment. ?
DocClox Posted May 13, 2019 Posted May 13, 2019 Why not indeed? Toothpaste not only tastes nicer, but it also won't glue your teeth together.
faky Posted May 13, 2019 Posted May 13, 2019 quite a few techtubers already dealt with that question so you can find a comparison between thermal paste, toothpaste, mayonnaise, ketchup and other stuff you can make at home. as far as i remember plain toothpaste was pretty good. i expect the graphite pads to become all the rage for casuals because of their ease of use and incredible lifespan though

Like me; you won't catch me dead using anything other than Arctic Silver 5. Work well with reseated GPU heatsinks to.

In fact, my experience has been that it's significantly louder than using only high-end fans. This is because the pumps make noise and they still use fans! I imagine there are some fanless variations out there. But, the typical water cooling system involves fans blowing at a radiator.
