I've had a 9560 and currently have a 9570. Both have cooling issues. Undervolting helps, repasting helps, but VRMS become an issue. A guy named iUnlock did a pretty crazy mod where he diverts part of the fan airflow to cool VRMS, which is indeed very helpful, but is way too much for almost every one. I'm glad to see dell added new chips, but unless they greatly improved the cooling, it will be for naught. Of course, the OLED is pretty great. I hope more laptops use it soon. Sad I'll end up waiting about six years before replacing, if I can get away with it. Also, Dell had better fix their bios bugs. The bios has issues, they reduced the tjmax for the nvidia gpu a few updates back, there are sleep bugs, processor state bugs, audio bugs, and many others. If Dell wants to pitch a premium machine, they'd better ship a premium firmware with it.

I've got the 9550 and run Ubuntu on it. No issues whatsoever and I do very compute-intensive work on it. One thing that I've found is very important is to clean out the fans often, otherwise dust builds up and prevents cooling. Just unscrew the plate on the underside of the laptop and blow / brush / pick out the dust that's built up (both the fan intake and the fan outlet). Doing this every few months has been a game changer for my 9550.

It's such a fraud that so many laptops are designed for burst but not sustained performance. Nothing's more awful than your video game completely crusting out 10 mins in and never recovering. I had a lot of luck adding thermal pads on a bunch of components on my xps-15. But the fact that I can alleviate the issues makes me wonder why they're not doing that at the factory.

  That't pretty much my thinking as well. If paste and pads do so much, and if diverting a little bit of fan flow helps as well, why does Dell not do so? The XPS division is run by the same guy who runs Alienware; why can they not get this right?

> I've had a 9560 and currently have a 9570. Both have cooling issues. Undervolting helps, repasting helps, but VRMS become an issue. I have a 9560, and would not have bought it if I was aware of the thermal issues. I'm very angry that this is even legal - Dell (and the other OEMs, including Apple) should be required to put big red signs everywhere if their customers cannot fully use the computer without buying it. By default, just stressing the CPU makes it downclock to the minimum of 800 MHz and the computer becomes unusable. Undervolting the CPU in Linux took an hour, now I can run it at max and the temp goes to 70/75 degrees with no performance issues. But using both the CPU and Nvidia GPU kills everything, since the GPU heat also spreads to the CPU. On Windows you can underclock the GPU but it doesn't make a big difference. Playing Overwatch at minimum settings and 1080p should work well on the GTX 1050, but I have to resort to hacks like limiting the CPU to 70% speed and putting a 70 FPS limit in Overwatch to keep the GPU from burning itself. And even then it stays at 90-95 degrees and sometimes crashes. Training neural networks was a bit more doable but still not fun. I have no idea how they put a 6-core i7 in the 9570 without it melting down. And this new 5GHz one seems similarly ridiculous. TL;DR just buy a gaming laptop - they're cheaper for the same specs and generally have a sturdy build. You might not get 10-12 hours battery and will need to carry around a charger, but the thermal issues are not worth it. Plus you get an Ethernet port included usually, and more USB ports.

  I have a 9570 with the 6-core CPU does stay over 3GHz under load and gets quite warm, but I think it's largely a function of them increasing the tolerances. I've rarely seen it dip down to the "base" clock speed of 2.2GHz.

  I've got the i7 9570; with undervolting, paste, and pads, it's pretty good. Though yeah, running with GPU is pretty much pointless.

  The Lenovo Thinkpad P52 looks like a pretty decent machine (but like you said, you'd need to carry around a charger everywhere) https://www.lenovo.com/us/en/laptops/thinkpad/thinkpad-p/ThinkPad-P52/p/22WS2WPWP52 https://www.lenovo.com/us/en/laptops/thinkpad/thinkpad-p/Thi...
