Pleasantly surprised
I received this today and immediately used it on a peltier thermoelectric cooling module. Right off the bat I got 10-12F drop in temp compared to without thermal paste. So I would say this thermal paste works very good, you get a generous amount, the price is good and the syringe it comes in is top notch. I would recommend this.

Reliable Thermal Paste at a Great Price
I’ve been using this thermal paste for a while now on different devices—my MacBook, an Xbox Series S, and my PC with a Ryzen CPU—and it’s been working great. Application is easy thanks to its smooth consistency, even if you’re not an expert. I really like that it’s not electrically conductive, so there’s no risk of short circuits. In terms of performance, I’ve had zero overheating issues on any of my devices. I use my PC for gaming and video editing, and the temperatures stay stable. Even on my MacBook and Xbox, where heat can sometimes be a problem, this paste has kept everything running cool. It’s also very affordable, which is a big plus. Because it’s a budget option, I replace it more often—about every 6 months—but honestly, for the price and the results, it’s totally worth it. The thermal conductivity is solid, and the paste holds up well over time without drying out too quickly. Pros: Easy to apply, even for beginners. Not electrically conductive—safe for CPUs and GPUs. Good performance across different devices (PC, consoles, laptops). Affordable and effective. Cons: Needs to be replaced more frequently than premium pastes (around every 6 months). Overall, this is a reliable, cost-effective thermal paste that works just as well on high-performance desktops as it does on laptops and consoles. Great option if you want solid cooling without spending a lot.

Good heat transfer compound.
I used this product for a DLP TV, the chip that produces the image for the TV has a great deal of heat on it. When the chip failed and I purchased a new one, I put this compound instead of the crappy sponge, that chip lasted twice as long as the original. Very durable for transferring heat, easy to apply and use. Versatile, used for PC heatsink compound, no issues with the material, sticks well and looks to have flakes of silver in it. Big tube, if you run out you build PC for a living.

Truly a lifetime supply
I don't know what I was thinking, but this massive supply was only a few dollars more than buying 2g. I only needed thermal paste for one server, but it was so much thermal paste I had to get it. The thermal paste doesn't seem abnormal in consistency and was easy to apply on the two Zeon processors. It might run a few degrees warmer than the top brands, however, the performance gap is negligible. Would definitely buy again, except I won't ever run out of thermal paste now. lol

Best value you can get for thermal paste!
I have read reviews and done my own testing, and this stuff(HY510) works just as it should. In certain scenarios yeah sure maybe some of the PREMIUM thermal paste is like 1-2% better? But... if you look at the pricing (not mentioning specific brands) its anywhere from an average of $1-$2 per gram. Thats fine for just an application or 2 but it runs out FAST when you like to test or are a system builder etc. If you do the math, that would mean that 100g of the other stuff would be $100-$200! Cost to performance ratio is not even in the same universe. I found my self doing more testing and building lately and I would run out of the expensive name brand stuff so so so fast. I have a life time supply of paste now with an order of HY510! Highly recommended.

Worth the purchase
Man, you never know when you might need a big tube of thermal paste. Bought one thinking it would go to waste after my initial use and I have ended up using it a few times now, essentially saving me money instead of buying small thermal paste tubes every time I needed to do something with my pcs.
