Halnziye HY-P17 and HM-806 Thermal Pastes Reviews
Thermal paste has a crucial role in the effective cooling of the main components, like the CPU and GPU etc. There are multiple factors contributing towards the optimal performance of the given thermal paste over the period of time, like its thermal conductance, viscosity, operating temperature range, make-up, electrically conductive, cure time, etc.
I have tested thermal pastes mentioned below from Halnziye earlier and found them to be high-performance, cost-effective options in their categories:
This time I am testing the following from Halnziye:
- HY-P17
- HM-806
Both are thermal pastes.
Pricing
It is important to pay attention to the packing quantity of the thermal paste when comparing the price. Here is the table:
| Thermal Paste | Quantity | Price (US $) | Price per gm (US $) |
| Halnziye HY-P17 | 4gm | 4.9 ~ 5.4 | 1.22 ~ 1.35 |
| Halnziye HM-806 | 4gm | 2.5 ~ 3 | 0.63 ~ 0.75 |
| Noctua NT-H2 | 3.5gm | 14.95 | 4.27 |
Please keep in mind that Halnziye is selling the thermal pastes in bulk quantity only, hence their pricing is reflective of that.
Closer Look
We will take a look at each of the Halnziye thermal paste one by one before moving on to the testing section. Let’s start with the high-end offer from the manufacturer: HY-P17.
HY-P17
The HY-P17 is the flagship offer from the manufacturer, taking over the HY-P16. It is provided in the paperboard packing in white. Salient specifications of the thermal paste are printed over here along with the features. This thermal paste is not a phase-changing design, unlike the HY-P16, which is phase changing. We have got 4gm packs.
The above picture shows the contents of the box. We have:
- TIM Spreader Card
- Spatula
- Grease Cleaners
The above picture shows the tube. It has a blue and white color with a blue color nozzle cover.
This thermal paste has 17.3W/mK thermal conductivity rating. From a rating alone point of view, this is top-notch number indicating that this paste is expected to perform that well in real life.
Specifications
| Color | Grey |
| Density | 2.6 to 2.7 g/cm³ |
| Viscosity @ 1rpm (Pa s) | NA |
| Thermal Conductivity | 17.3 W/mk |
| Thermal Impedance | NA |
| Thicotropic Index | NA |
| Working Temperature | NA |
| Material | Silicon Based |
I don’t have more data on this thermal paste. It is silicone-based, using aluminum oxide and zinc oxide in 60-65 and 20-25 percentages respectively, with the dimethyl siloxane in 12-15%. This thermal paste is drier than its predecessors. It is gray color, odorless paste.
You will get a smudgy, sludge sort of paste, which is dry. It is quite difficult to even spread this thermal paste. A better alternative is using 9 small dots on the IHS, or 5 medium dots, depending on the SKU, and the rest of the job will be done by the cooler’s weight and mounting pressure.
HM-806
The HM-806 is another new thermal paste from Halnzyie in the HM category. The paste comes in 2gm and 4gm packs. The shipping box is made of paperboard material, which is finished in red and black colors.
The above picture shows the contents of the box. We have:
- Spatula
- Grease Cleaner
- TIM Spreader Nozzle
- Finger Cover
The above picture shows the tube. It has a black wrapper with a black nozzle cover. HM 806 is printed in white.
The thermal conductivity rating is 14.6W/m-k, whereas the HM-805 has a 12.8 W/mK rating.
The above picture shows gray color thermal paste during its application on the CPU.
Specifications
| Color | Grey |
| Density | 2.5 to 2.6 g/cm³ |
| Viscosity @ 20ᵒC | 150 to 160 Pa |
| Thermal Conductivity | 14.6 W/mk |
| Thermal Impedance | 0.001ᵒC – in²/W |
| Permittivity | 1.8 @ 106Hz |
| Volume Resistivity | 2.0 x 1013 Ohm.cm |
| Dielectric Strength | 1.0KV/mm |
| Working Temperature | -30 ~ 150ᵒC |
| Shelf Life | 5 Years |
Like the HY-P17, the HM-806 is also dry, hence it is not easy to even spread it on the CPU even after warming it in a hot cup of water. You can use the same dot method for this thermal paste as well. It is also a silicone-based material which is electrically non-conductive. It is available in syringes, buckets, tubes, and can packaging.
Testing
The following configuration is used for thermal testing:
- AMD Ryzen 9 9900X
- ASRock X870E NOVA WiFi
- GSkill TridentZ NEO RGB 32GB 6400MHz CL30 DDR5 kit
- ASRock Phantom Gaming RX 7600 Graphics Card for Display
- Biwin Black Opal X570 Pro 4TB NVMe SSD
- Fractal Design ION+ 2P 860W Platinum PSU
- Thermaltake Core P6 TG Snow Edition in an open frame layout
Here is the settings table for testing:
| Settings | PBO Enabled [243W] |
| Clock (MHz) | Auto |
| Voltage (V) | Auto |
| Thermal Paste | Noctua NT-H2 |
| Thermal Paste Application | Dots Method |
| Test Run Time | 30 minutes |
| Idling Time | 10 minutes |
| All Fans Speed | 100% PWM Duty Cycle |
| Pump Speed | |
| Stress Software | CINEBENCH R23.2 |
| Monitoring Software | HWINFO64 |
I am reporting absolute temperature in the graph because the room temperature was at 22°C throughout the day. The testing is done on an open-air bench system. Once inside the chassis, the temperatures are expected to rise and would largely depend upon the optimal airflow inside the chassis.
Result
Let’s take a look at the results.
The Idle temperature is not showing anything conclusive. This is mainly due to the beefy cooler being used.
The results are quite impressive for the Halnziye HY-P17 and HM-806. There is not enough data in the graph, but for the purpose of testing, the results are valid.
Conclusion
In this article, I have taken a look at the following thermal pastes from Halnziye:
- HY-P17
- HM-805
Each of these thermal pastes has different thermal characteristics. They are non-cured, non-electrically conductive pastes. The HY-P17 is the flagship offering from the manufacturer, and it is not a phase-changing design like the HY-P16. The HM-806 takes over the HM-805 while offering a marginal gain. Both thermal pastes have gray color, though HM-805 has a more whitish tone. Both are silicone-based compositions using zinc oxide and aluminum oxide.
Both thermal pastes are challenging to even spread, hence I resorted to the dots method (not a single dot) during thermal testing. The HY-P17 is available in 2gm and 4gm packs, whereas HM-806 is available in large capacity and various sizes as well like bucket, can, syringe, etc.
HY-P17 is clearly for the enthusiasts, overclockers who would want nothing but the best performance, leaving no corner uncovered, though thermal pads are there to take the game further ahead. The HM-806 is more of a mainstream application use.
The thermal conductivity rating of these pastes are:
- >14.6W/m-k for HM-806 (12.8 on HM-805)
- >17.3W/m-k for HY-P16 (16.1 on HY-P17)
Halnziye has supplied a spatula, finger cover, and card spreader with HM-806, whereas the HY-P17 comes with a spatula and card spreader. There are also grease cleaners in the packaging to clean the CPU surface.
The pricing of these thermal pastes is as follows:
| Thermal Paste | Quantity | Price (US $) | Price per gm (US $) |
| Halnziye HY-P17 | 4gm | 4.9 ~ 5.4 | 1.22 ~ 1.35 |
| Halnziye HM-806 | 4gm | 2.5 ~ 3 | 0.63 ~ 0.75 |
| Noctua NT-H2 | 3.5gm | 14.95 | 4.27 |
The Halnziye thermal pastes carry 5-year warranty and their pricing is quite effective as well. Based on the pricing, warranty and thermal performance, these pastes come recommended by us. If you want more technical details with more in-depth tests, please hop on to Igor’s lab website.
