Note that there are 3 variations of paste available, STC 7(4grams), STC 8(1.5grams) and STC 9 (4grams). The STC 8 is a lot smaller tube.
Presumably the STC 9 has the best thermal conductivity at 9.1 W/m-k. In theory people should be buying that for the small price difference and larger quantity.
Overall, no complaints about this thermal paste, large quantity, easy to spread, seems to transfer heat. The STC 9 also comes with a spreader. Ingredients in the STC 9 are Silicone Oil, Alumina, Aluminum, Zinc Oxide. As far as I can tell this looks similar to the Tech Ingredients DIY thermal paste that gets rave reviews online. Find Tech Ingredients “Make our Best Thermal Paste…” video on YouTube and it has a formula link in the description. Then search for other reviews and videos online about that paste, if interested.
No reason not to but the STC 9 paste. Can’t go wrong.

For being the cheapest thermal paste on Amazon that can be delivered with prime, it’s an amazing product. CPU temps went from 160F to 100F.

My Ryzen 5 non-overclocked 2600 was hovering at 50c plus idle. The Ryzen 5 2600 has a rating of 65w tdp, so I don't understand why it runs so hot. I bought this thermal paste along with a 30 dollars cpu cooler. Now my cpu temp is around 40c idle and 60c gaming. I also used it on another computer, and that one dropped around 6c idle.

Noticed I was having over heating issues with my PS3 console, so I upgraded the fan and found I needed to replace the thermal paste on the chipset as well. This was the perfect amount, used almost the whole thing, it's actually a really small tube of thermal paste but just the right amount I needed. We'll see how it goes.
(UPDATE) After install of thermal paste this works great, no more over heating issues what so ever, would recommend.

Finally something that works. You will not have left overs. They give you enough for for one CPU. For the price no bad and easy to apply. Buy it I command you.

グラボの冷却フィンを清掃したときに使用
Reviewed in Japan 🇯🇵 on February 2, 2021Size: STC 8Verified Purchase
古いMac Proが突然画面表示できなくなり、ダメ元でグラフィックボードの清掃をしました。プロセッサと冷却フィンの間に塗られているグリスを拭き取り、このグリスを塗って組み立て戻したところ、無事に復旧してほっとしました。
一回の使用には十分すぎる量です。以前に使った別のグリスを机の引き出しに保管していたところ、数年ぶりに取り出してみたら固まっていて使い物になりませんでした。今度はそうならないことを祈っています。

今まで使っていた他社メーカーのと比べ、特に良くなった悪くなったというのはありません。
高負荷の作業をすれば変わるのかもしれませんが、自分は書類整理とネットサーフィン位で負荷を掛ける様なことが事が無いので、他のグリスとの違いは分かりません。
ただ、若干硬めなので塗りにくく、外す時にスッポンが怖いかなと思ったくらいです。
