Noctua NT-H1 3.5g, Pro-Grade Thermal Compound Paste (3.5g)

I’ve used the Noctua NT-H1 thermal paste on a couple of CPU installations now, and it’s been consistently excellent. Application is very straightforward — the paste has a good consistency, neither too runny nor too thick, which makes spreading or using the pea method easy and predictable. It doesn’t dry out quickly during application, so you’ve got a bit of working time to seat the cooler properly. In terms of performance, it does exactly what you’d expect from a quality thermal compound. Temperatures remain stable under load, and I’ve seen solid results both at idle and during more demanding tasks like gaming and rendering. It’s not flashy, but it’s dependable — which is exactly what you want from thermal paste. Long-term stability is another strong point. Once applied, it doesn’t require frequent reapplication and maintains performance over time, which is ideal for builds you don’t want to keep reopening. The only minor drawback is that the tube is quite small at 3.5g, so if you’re doing multiple builds or frequent repasting, you may run out sooner than expected. That said, for a typical single PC build, it’s more than enough. Overall, this is a high-quality, no-nonsense thermal compound that delivers consistent cooling performance with minimal hassle. A very safe choice for both beginners and experienced builders.

I used a different brand I was peaking at 100°C with my overclock so I bought this and it drop it to 80°C. Very good result

I have used this product before and would highly recommend. All Noctua products have been exemplary and would easily recommend.

Noctua NT-H1 is excellent thermal compound. It spreads smoothly, gives great contact right away, and keeps temperatures nice and stable even under heavy load. The 3.5g syringe is enough for several applications, and the paste stays consistent over time with no drying out or pump out issues I've seen. Non conductive, easy to clean up, and performs exactly as you'd expect from Noctua. Solid choice for any CPU or GPU.

I repasted my 2020 MSI GE66 laptop after 3 years and wow the performance is crazy. The laptop had developed lag and other graphical issues but after this repaste the laptop runs 20-30 degrees cooler and the Noise is far less. The laptop runs well and the paste was easy to apply. I wish it came with cleaning wipes but I used a Q tip with Alcohol and got rid of the old paste. Id say 1g is all you need for a laptop and now I have excess laying in my drawer. Ill probably repaste it in 2 years again as the size if the pack is good for the cost.

Replaced my old cpu, this was smushed on the new one. Pc working lovely.

Nice quality thermal paste, help to reduce heat temps on CPU.

Worth the money, easy to spread, it's thick enough the it doesn't run but thin enough that it spreads easily. It's great at lowering temps and I use this on every build I do.
