## Description

PTM7950 31x50x0.25mm Phase Change Thermal Pad, JOYJOM High Conductive Silicone Grease 8.5W/mK CPU Thermal Paste for PS5 Steam Deck ROG Ally CPU GPU SSD M.2 Laptop

Review: Works amazing! - I bought this for the steam deck to see if I could drop the temperatures as I've heard good reviews on this phase changing thermal paste. All I can say is the photos literally show proof that this stuff works, I have added a before and after photo, game tested was Ragnarok. CPU temperature dropped about 7c Whilst the GPU drop a crazy 13c Literally looks for your self. I'm very happy with this purchase and will definitely be buying more for anymore future projects of mine :)
Review: The performance is good, my omen 15 cooled down by 8-10 degree Celsius. Previous peak was nearly 100C at max cpu performance now it's closer to 85-88. Gpu also stays below 70. Good product, though quantity is less, it is enough for 2-3 repastes. i think it should last 1 year per repaste

## Features

- 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

Put this on my rtx 4080. Taking apart the GPU was pretty simple. I cut the pad down to fit the die and it worked perfect. Temps dropped around 10 degrees celsius.
