(This is a thank you note to LMG so if it belongs better in a different forum, feel free to move it and remove this blurb afterwards.) My (and others') ThinkPad T480 has had significant thermal issues from the start (see Reddit and NoteBookCheck for details on the problem with discrete GPUs). Unfortunately, I bought it and moved into it before discovering the problem. Since then, Lenovo and its customers have tried different solutions that include: throttle everything if the CPU or GPU get too hot, change the PL1 limit whenever things get warm, and make the (single) fan spin faster or slower. In the last few months, I had trouble understanding the latest changes from Lenovo and experienced inexplicable PL1 throttling whenever I watched your company's videos at 4K. Since I've seen HWINFO64 in a lot of the videos, I tried using it to supplement Throttle Stop and TPFanControl and found that HWINFO64 was extremely useful, especially the time series graphs. I'm sure you never dreamt that someone would use your videos as a stress test on a modern business laptop or that background software that you never explicitly call out would be a major takeaway but that's how things turned out. Thank you so much for the videos and high-quality uploads in every sense of the phrase "high-quality". The following videos were especially helpful: - FAP: YouTube 4K explained - LTT: Why shoot in 8K? Since this post is in the Laptop Forum, then on a practical note for non-LMG people hoping for a solution to "Lenovo battles the Intel heat and fails"...bad news. In HWiNFO64, I observed that whenever the CPU package temperature exceeded 60 degrees Celsius, the PL1 limit began to drop. When the CPU package temperature is less than 55 degrees Celsius for a while, then the limit goes up. The PL1 limit's floor is about 5.5 W, which results in clock speeds below 1 Ghz My long-term plan is to buy a P53 because I bought one recently for someone else and it seems to avoid noticeable throttling even after playing Untitled Goose Game for a while. I'll be re-testing now that I have fancier software tools but I expect it will continue to be a fine choice. My work computer (Latitude 5480) also struggled to remove heat in the past and now cools itself by making a racket. After watching numerous LTT videos and Taran's comments on his Razer Blade, I've concluded that if I have to go with Intel, I have to get something that's chunky enough to have a good cooling solution. One of these days, perhaps AMD will make sufficient inroads into the laptop world. In the short-term, I'm using MSI Afterburner to cap the wattage going to the GPU, TPFanControl to make a terrible din (and move as much air as possible), RW-Everything to disable PL1 and PL2 throttling, and and working as fast as possible to deal with some personal things so I can switch laptops. I may also replace the thermal compound and blow out the fan to buy extra time. I will also have to stop watching LTT videos in 4K and give up on playing computer games.
