Revisited: Level51 Forge 15 series - with CM Mastergel Maker paste

Retested thermals of Forge 15 series with CM Mastergel Maker, some interesting results.

Notes:
  • Ambient temp is around 26C
  • Auto fan curve is used
  • There is CPU undervolt of -50mV by default. Custom undervolt is -100mV (highlighted in blue colour)
  • Thermal paste application method - CPU: line method, GPU: X method
  • Laptop is plugged in

 Forge 15 (i7-9750H, GTX1650)
CPU - Aida64 FPU only: Performance mode (PL1 60W)
Stock: 80-82C, 3.11-3.13GHz
UV: 80-81C, 3.25-3.26GHz
UV+PL1 75W (override): 91-94C, 3.51-3.53GHz

PL1 cannot be 80W or more, otherwise VRM will throttle

GPU - Unigine Heaven: With CPU UV, CPU disabled turbo, Extreme profile, windowed mode
60-62C, average ~1683MHz

Aida64+Heaven: Max fans enabled, CPU UV
CPU: 55W (capped), 90-93C, 3.13-3.19GHz
GPU: 50W, 75C, average ~1588MHz

Enabling max fans will have the same result in CPU or GPU only load.

Forge 15 Elite (i7-9750H, GTX1660Ti)
CPU - Aida64 FPU only: Performance mode (PL1 60W)
Stock: 79-80C, 3.27-3.28GHz
UV: 79-80C, 3.4-3.42GHz
UV+max fans: 77-78C, 3.41-3.43GHz

PL1 cannot be 80W or more, otherwise VRM will throttle

GPU - Unigine Heaven: With CPU UV, Extreme profile, windowed mode
72-73C, average ~1747MHz

Aida64+Heaven: Max fans enabled, CPU UV
CPU: 50W (capped), 3.19-3.22GHz, high 80C
GPU: 80W, 83C, average ~1696MHz

CPU: 45W (capped), 3.04-3.09GHz, mid-high 80C
GPU: 80W, 82C, average ~1696MHz

Forge 15 Pro (i7-9750H, RTX2060)
CPU - Aida64 FPU only: Performance mode (PL1 60W)
Stock: 80-90W, 80-89C before PL1; 73-75C, 3.22-3.24GHz
UV: 72-74C, 3.35-3.38GHz
UV+PL1 75W (override): 82-84C, 3.68-3.7GHz

PL1 cannot be 80W or more, otherwise VRM will throttle

GPU - Unigine Heaven: With CPU UV, Extreme profile, windowed mode
67-68C, average ~1510MHz

Aida64+Heaven: Max fans enabled, CPU UV
CPU: 50W (capped), 86-88C, 3.17-3.19GHz
GPU: 80W, 78-79C, average ~1439MHz

CPU: 45W (capped), 83-84C, 3.03-3.05GHz
GPU: 80W, 77C, average ~1456MHz

Enabling max fans will have the same result in CPU or GPU only load.
  • Lifting the laptop will drop around 2C for both CPU and GPU
  • GPU temp is high in both Elite and Pro - might be due to insufficient thermal paste due to big die size. Will have to confirm again in another retest. Maybe I'll try spread method as suggested by Level51

[GUIDE] How to undervolt laptop (Intel CPU and Nvidia GPU, 2021 revised version)

This is my own guide on how to undervolt Intel CPU / Nvidia GPU in your laptops. Hope you found it useful! Notes: This is my own method on how to do it. There are a lot of ways to undervolt CPU+GPU, but this is how I usually undervolt with all the laptops I had reviewed and with my own laptop I will try my best to make the explanation clear and will be using the undervolt profiles in my laptop as example As mentioned in the title, this guide is for those with Intel CPU (4th gen or later) or Nvidia GPU (10 series or later) or both only. Some laptops have BIOS version with Plundervolt patch that locks CPU voltage control, so take note You might brick your 10th/11th gen Intel laptop if you undervolted too much even with software like Throttlestop, I will not be responsible if something catastrophic happens To TGL-45 laptop owners: Only i7 and i9 has unlocked CPU voltage control, even so the laptop model itself might not allow you to undervolt the CPU. Check your laptop model first

There is only minimal screen wobbling and the lid can be opened with one hand. The hinge is smooth and well calibrated. The bottom chassis, including  the keyboard deck and C cover, has only minimal flex when force is applied on it or twisted. Overall, buil
