Review
It's 100% real but I gave it 4 stars because of the tube size first I read all the reviews I got scared that I thought it will be fake it you use it in correct way it will work and I used it in my PS4 now the temp is down and it's not giving any messages like. Your PS4 is too hot

Not too musch
I didn't see any of temp low after using it also used it two times because I thought it's my mistake for putting on the CPU but doesn't give a low temp. same results

Thermal Grizzley Extreme paste
Product arrived on time and in perfect condition. I’ve used Thermal Grizzley products and they perform well. CPU temps are always at 29 C and lower at idle. Heavy gaming temps run at 60 to 70 C. CPU is an Intel 13900ks. Would recommend this thermal paste.

This thermal paste is excellent for what it’s meant to do. I’ve used it in a few builds now, including high-load systems, and it delivers consistently good thermal performance. It spreads smoothly, fills gaps well, and lets your cooler do its job without adding a bunch of fuss. A little goes a long way, and even though the tube is just 1 gram, it’s enough for a couple of applications without waste. Installation was simple and clean, and temperatures have stayed nice and low under sustained load. If you’re pushing performance or want tighter thermal control, this paste is a noticeable upgrade over basic stock compounds. It’s not a huge, earth-shattering difference for casual use, but for enthusiast builds or more demanding systems it’s definitely worthwhile. Great balance of performance and ease of application, and well worth having in the toolkit.

Still top tier quality! I never used anything else.
I always order the larger tube since it lasts me about 2 years and I am constantly refurbishing/building computers. Whether it is a laptop or gaming PC, you just cannot go wrong with Thermal Grizzly. I probably apply this well over 40 times with the larger 10ml size on both CPU's and GPU's. Compared to the factory paste, it is day and night. I would not recommend the big tube unless you're constantly applying it on hardware as you probably won't need it. I have also tried other brands and the consistency of this product after 2 years of owning it is the reason I keep buying it in larger sizes. Other brands tend to dry up and lose their quality much faster.
