Till it all gets to temp then it won't do much. It needs some more surface area to convect heat better. With enough fins you don't need fans.

A block of diamond would be even better (copper being at 401 W/mK, Diamond at 3320 W/(mK), almost 10x better) |

Would a slow small fan still make a huge difference to the cooling here? Completely passive cooling seems like something that would only make sense in very specific professional environments (like needing an ultra low sound floor in an audiology chamber or recording studio). |

Is your motherboard connected to two giant case-sized heatsinks? I'm struggling to see the big picture here |

with the way prices are going, carbon based heat dissipation may become the preferred option how pretty would it be if it was a tree-like crystal structure |

But only 3-5 diamonds are generated per chunk, requires an iron pickaxe, and usually doesn't start appearing regularly until Y level 14. Meanwhile copper can have up to 16 veins of copper per chunk, requires a stone pickaxe, and appears most frequently at Y=48. Copper is clearly more accessible for making ore blocks. Wait a sec, this isn't !minecraft@lemmy.world |

With big enough copper block it might not matter (like the size of a house, but of the good quality stuff not that shit Ea-Nasir sells). |

I had a roommate who was getting his doctorate in chemical engineering, specifically focused on graphene. He was able to demonstrate how doping the materials in a heat sink to alter their ability to "release" heat, and then organizing these intentional hotspots along the length of the fins, you could create an active airflow using a stationary object. But then his lab manager killed his grant and instead put him on a project partnered with BMW to make their bumpers more marketable. |

This is after 1.18, Diamonds are most commonly found at Y=-54 now. |

The empty copper block is for a GPU, but I'm running this primarily as a silent server so I didn't bother with the GPU since it has integrated Graphics. |

The case has an opening for a vertical fan but it is not needed unless you do heavy gaming and run a high end GPU. For video rendering and other tasks the fins are rated to keep it at a decent temp. I have good hearing, and a HDD spinning or even a "silent" fan is still audible droning noise to me. This build is totally silent. The PSU is over-rated on purpose because it has a below 30% max draw mode that is fanless. |

Its a monsterlabo case, they made fanless heatsink systems...I think they may have gone out of business a few years back because a silent case is very niche. https://www.vortez.net/news_story/monsterlabo_the_first_chassis_now_available.html |

It's a monsterlabo case. They used to make a few models that were all heatsink so you didn't need fans. I think they might have gone out of business because their website has no stock left for ordering, etc. Too niche a product to sustain sales probably. Edit. No website anymore either. But here's the case I have. https://www.vortez.net/news_story/monsterlabo_the_first_chassis_now_available.html |

Okay, who gets to be the lucky one to calculate the amount of time that thing could heat sink a pegged, modern, 120w TDP CPU before it throttles at 100C? I'll give you a sticker. |

Let's assume the dimensions of the copper block are 40mm40mm160mm (I'm not taking the heat spreader into account here) That results in a volume of 256000mm3, or 256cm3 Copper (at 20C) has a density of 8.935 g/cm3, so that's roughly 2.28736kg of copper Copper has a specific heat capacity of 384.603 J/(kg K) Using E=cm∆t, we can figure out that it would take ≈ 70378J of energy to heat the copper block to 100C, starting at 20C With a TDP od 120W, that means it would take 586 seconds to heat the block to 100C, or 9m46s This is probably way off but I was bored |

Hmm, I think at minimum calculus will need to be involved here. Because we can't just assume that the heat is spread evenly in the copper - it'll likely be hotter at the bottom, leading to thermal throttling earlier than expected. On the other hand, there's going to be heat dissipation into the air, which will help cool the block somewhat Edit: made a program to model heat transfer and heat loss. It seems to only affect final time by a handful of seconds. So actual time in real life is probably somewhere in the ballpark of 10 minutes |

Toblerone has famously been shrinkflating their product for some time. I remember seeing a comparison post many years ago of a modern one vs one that had been bought years ago and rediscovered in a closet or drawer or something. The older ones had thicker spikes. |
