DEEPCOOL DM9 professional-grade thermal paste 1.5g

Great for CPUs but not for toast Great for CPUs but not for toast

Packaging is neat. Product also includes a grease remover and a nice little plastic spatula tool to help apply paste. Only con would be that it isn't very much, meaning if you mess up you'll more than likely need to apply another tube. Packaging is neat.

PBTech was easy to work with. I have one down the road so I ordered it and popped on over when it was ready. I cleaned up my machine and re-installed the CPU chip. Temperature came down from 70-85 back down to 45-55. PBTech was easy to work with. I have one down the road so I ordered it and popped on over when it was ready.

This performs very nearly as well as the market leaders (Grizzly, etc) but is around half the price.

I found it easy to apply.

It comes with an alcohol swab to clean old paste off your IHS, and a little paddle to spread the paste. This performs very nearly as well as the market leaders (Grizzly, etc) but is around half the price.

good thermal paste good thermal paste

did the trick. easy to apply. did the trick. easy to apply.

My cpus thermal paste had gotten crusty and dry so my temps during normal gaming loads were exceeding 70°-80°c, this thermal paste had brought it down to 60°-67° at it's highest load. Great performance and affordable price however I did struggle to spread it well with the spreader it came with because of the consistency of the paste, the spread ends up looking streaky and strings of the paste end up getting pulled and end up all over the cpu. Probably best to use the pea sized dot + squish with the heatsink method to apply this thermal paste.

Used this for my Ryzen5 5500 and aio and it works amazing.
also used this to repaste my 1060 6gb for overclocking and helped keep my temps down and stable. Used this for my Ryzen5 5500 and aio and it works amazing.

Does the job, have used for 3 cpus so far. Does the job, have used for 3 cpus so far.

💻 Used With: AMD Ryzen 5 9600X + DeepCool LD360 AIO Cooler
🔧 Purpose: Maximize cooling efficiency on a 4K gaming + Adobe editing PC build

🟢 Pros:

✅ Smooth Application
The DM9 thermal paste has a perfect texture — not too thick, not runny. It spreads evenly and easily with just a small drop or an X pattern. Great for both beginners and experienced builders.

✅ Improved Thermal Contact
After applying it to my Ryzen 5 9600X with a 360mm AIO, I noticed stable temps and faster cooldown under load. No dry spots or overheating — even during 4K rendering and long gaming sessions.

✅ Non-Conductive & Safe

✅ Non-Conductive & Safe
It’s electrically non-conductive, so I didn’t stress about accidental over-application or edge contact. Peace of mind during install.

✅ Enough for 2–3 Applications
The 1.5g tube gave me enough for 2 full CPU applications (or 1 CPU + 1 GPU, depending on your setup). Good value for small builds or single-use builds.

🔴 Cons:

⚠️ No Spreader Tool Included
Some premium pastes include a spreader — DM9 doesn’t. Not a big deal since the pea/drop method works fine, but it’s worth noting.

⚠️ Single Small Tube Only
If you’re doing multiple builds or applying to both CPU and GPU, you may need more than one tube.

🎯 Final Verdict: 8.5/10

The DeepCool DM9 Thermal Paste is a reliable, easy-to-use compound that performs great with high-end CPUs and AIOs. For the price and size, it’s an excellent choice for one or two quality installs — especially for creative/gaming rigs like mine.
