上網睇人講話會有八十幾度會唔會太熱呀

AMD原裝果個heatsink都係廢廢地,有$$$就買隻好D的cooler

機箱散熱夠好, 只打機, 或睇下youtube, 原裝散熱可能夠用, 唔會80幾度.

長時間80幾度就唔係幾好.

買散熱器不如買個散熱好的箱

我粒3600用緊隻NH-U12S, 原裝heatsink......算把啦

唔用機箱、散熱器,就咁用把16”強力叭地扇吹住都唔過40℃,自己諗下個原理…

唔打機原裝夠,打機最好買散熱,機箱都要多兩把風扇

我自己用的是銳龍R5 2600X,散熱器用的玄冰GT,溫度待機40-50,感覺也是頗高,之前也糾結,但始終沒有辦法降下來,索性就破罐破摔了。

我剛轉用R9 3900X, 唔打機情況下, 用原裝風扇都係60幾度.
你怕熱, 其實可以將原裝風扇個轉速調去High, 應有啲幫助.

講多無謂, 睇片最實際: https://www.youtube.com/watch?v=ke3OnFlOUnI


睇樓上留言簡直就係好笑, 80 度根本唔係問題, 仲要係 full load 先至係呢個溫度. Stock cooler 夠用, 唔好畀人誤導要什麼 NH-D15, Dark Rock Pro 4, 等等.

3900X 就唔好用 stock cooler, heavy load 好炆. 成四千蚊嘅 CPU 就唔好慳四百蚊 cooler 錢. 3600 先至千五蚊, full load 都冇問題就話唔洗另買 cooler, 溫度及 cooler 唔可以同 3900X 相提並論.

ryzen3000出了後, 忽然80度又不熱了.


It has proven by data that in semiconductor and electronic parts, failure rate hugely increases depending upon heat and life shortens.

Electromigration decreases the reliability of chips (integrated circuits (ICs)). It can cause the eventual loss of connections or failure of a circuit.
高溫會加速電遷移.

Chips are typically designed for EM for the expected lifecycle of the product to minimize field failure. 80C is well within design specs, which typically guarantees normal operation between around 0-100C depending on the design. Most people won’t even notice a shortened lifecycle because after a few years it’s time to upgrade anyway.

AMD CPU 3年limited warranty. 3年後壞, 都可以叫 within spec, design.

In order to warrant 3 years of normal operation the chip must have been designed to work well past 3 years. You never target your design to the mean of the expected distribution. Chip designers are way more concerned about not having design flaws than software designers because of the huge cost of doing respins.

You are comparing apples and oranges. Power supply wires are so thick compared to ICs that they don’t have EM issues. Chip design does not have  unlimited resources.To guard against potential EM violations in chip design one needs to use extra resources, resources that could otherwise be used to improve other aspects of the chip. Higher voltage, increased frequency, hotter temperature, and smaller feature size all contribute to worse EM conditions, but performance is what sells chips. There is no incentive to design for a 10 year life span when chip generation turn over every few years. Of all the different things that worry designers at chip tapeout, EM is not at the top of the totem pole. If one is concerned about cpu longevity, don’t overclock the thing.

power supply 都有IC, 電路板, 電容. 全部都受高溫影響.
power supply 80度隨時都仲可以運作一段時間, 不過不是十年吧.

根據我既經驗如果部機係近乎長開,任何零件超過70C都係唔OK


CPU高熱燒既九成九唔係CPU,而係主板上既mosfet或電容

Talking to him is a waste of time. He's an AMD hater. 80 degrees Celsius is well within safe margins, and it's a full load temperature, so it's not even a regular use temperature.
Everyone around the world is shifting to AMD already. Even Google data centres are moving to AMD's Epyc chips. If that doesn't spell out the story of where the world is heading, then nothing will, but there are people like him that hold onto legacy beliefs from the early 2000s.

師兄是有份設計ryzen cpu?
以你的專業見識, 新ryzen3000 的 RDRAND 指令bug是不是冇得用AGESA修理? 要等respin所以咁耐都未修好 RDRAND BUG?

Nope, I was completely not involved. My time with AMD was ancient history. I also don’t follow news on whatever bugs they’re having. However, I would say that as a general rule, chip makers will avoid redo-ing masks as much as possible because it is very costly. If they can find a way around the problem in software they would. Also, if they have to respin, they would wait to collect and resolve as many issues as possible and fix them in the same rev, because, again, each spin cost a lot of money. Actually some fixes may cost more than others to implement and that comes into the decision making as well. They will evaluate the trade offs between fixing something and the cost of fixing them, just like any other business would.

原裝散熱唔開PBO 夠用


Intel 個散熱一樣咁廢, 9400 用電仲比 3600 多少少, 都夠用

CPU 溫度呢樣野, 同一款先有得比較
同一粒CPU die 唔同位置溫度都唔一樣, 差到二十度以上

Ryzen gen3 唔係單晶片,因為總有段差所以係用墊過heatspreader,散熱能力比intel更低(intel都唔係特別好),而且如果d墊太熱恐怕會隨時間變質(intel用散熱膏都有同樣既問題,但因為溫差比較小一般耐用得多)

雖然咁既損壞修理唔難,但感覺上佢始終係粒為左減成本既同時削弱左可靠性既CPU

如果部機長開CPU超過80C無論係intel定amd接heatspreader既料都應該會在幾個月內烤壞

焊錫邊有咁易死

CPU 比你睇個溫度本來就係一個相對既數字
intel core 80 度本來就係平常事, sandy bridge 大把人長超都用到宜家
notebook 上既CPU因為有 turboboost 散熱又雞經過都會破90 度, 咪又係無事
AMD 一樣,FX 8350 又係大把人長超用四五年

樓主你要知道網上有好多既得利益者 ,大力 推廣原裝散熱器唔夠力,要另外購買散熱器先至可以 為cpu散到熱。
但係你要知道很多廠機 的散熱器 都 係 普通鋁散熱器, 有啲比原廠散熱器更差, 但係很多公司用成10年以上
