- PTM7950 is a highly thermally conductive Phase Change Material (PCM) that lasts longer and is more effective than tradiational thermal paste.
- Size 31x50x0.25mm, Phase change at 45°C, Thermal Conductivity: 8.5 W/m.K, It is normal for it to melt at high temperatures.It achieves good heat dissipation performance through repeated melting and solidification. Note: it requires technical and operational skills, it is recommended to use under the guidance of professionals
- PTM7950 is a proprietary material that provides superior reliability (pass 150˚C baking 1000 hours, T/C-B 1000 cycles) and maintains low thermal impedance (<0.04˚Ccm2/W @ no shim), making the PTM7950 series desirable for high performance integrated circuit devices.
- PTM7950, based on a novel polymer PCM system, exhibits excellent interface wetability during typical operating temperature ranges, resulting in extremely low surface contact resistance.
- Package include: 1x PTM7950 Thermal Pad 31x50x0.25mm, 1x Screwdriver, 1x Cleaning Wipe, 1x Spatula, Finger gloves, 1x Cleaning Brush
Product Description
- PTM7950, a high thermal conductive Phase Change Material (PCM) in pad format, was designed to minimize thermal resistance at interfaces and has the great excellent long term reliability.
- Based on a novel polymer PCM system, this material exhibits excellent wetting at interfaces during typical operating temperature range, resulting in very low surface contact resistance.
- A proprietary filler material provides high thermal conductivity 8.5W/m ·K and a low thermal impedance (<0.04˚C cm²/W), suitable for high performance IC devices.
how the PTM7950 thermal pad works ?
At room temperature, thermal conductive phase change materials remain solid and cannot discharge air from the interface (Picture 1)
As the temperature increases, the phase change thermal conductive material becomes softer and the air at the interface begins to be discharged, and the temperature also begins to decrease (Picture 2)
When the phase change thermal conductive material reaches the phase change temperature(45°C), it becomes liquid and can greatly wet the interface, discharge the air inside the interface, reduce the interface thermal resistance, and transfer heat as much as possible; When the device is in a non working state, the phase change thermal conductive material becomes solid again, but maintains 100% complete wetting of the interface (Picture 3)
Easy to use, Noted: thermal pad is gray, the protective film may be clear or blue, so it is normal if looks gray or blue
Widely Application
8.5W/mK high heat dissipation performance.Effectively improve the performance of notebook computers, cpu, ssd, gpu game consoles or other integrated circuit chips.
FAQ:
Q: Why did I receive it in blue, picture is gray?
A: the thermal pad is gray, but protective film is blue or clear, please remove the film before using
Q: Can it be used together with silicone grease?
A: No, it needs to be used separately to replace silicone grease
Q: Can it be used in multiple layers?
A: No, it can only be used in a single layer. The standard thickness for applying silicone grease is 0.25mm.
If it is too thick, it will affect the heat dissipation effect
Q: Why is the cooling effect not obvious when used on desktop computer at the beginning?
A: it is phase change thermal pad, when the thermal pad becames liquid in high temperature,
it will have good heat dissipation, you can use the computer in high termperature 2-3hours
and repeat many times to discharge air, the effect will be better.
Q: How durable is the 7950?
A: On mobile core gaming laptops, durability is very outstanding, and there will be no significant
attenuation after one year of high intensity use (except for dust blockage and defects in the
computer's own heat sink)
Q: How long can the 7950 be stored?
A: Sealed , avoid light, 2 year
