@ejn63​ i have done a thorough cleaning when I first got it, cleaned the fans, changed the thermal paste for some new Arctic MX4, I thought about that, but I don't think I noticed anything abnormal with task manager, but I'll check some more

i did some tests using AIDA64, namely a stability test, and although after the fans kick in the thermal throttle is at 0% i still find the mouse kind of catching, or hanging every second basically and the graphics card that is in use is the integrated one, and the nvidia one seems to be randomly going, from 0 % to 100%, and the system might be hanging every time the nvidia card kicks in, although i am not very sure, will continue to monitor these things

I've had this issue for SO long. I don't have a solution yet. I think it's just VERY poor thermal regulation and Dell simply doesn't care. I've just gotten my heatsink and fans replaced, and the issue does not seem to be resolved. At one point I had modified some bios settings to disable the laptop attempting to manage its own processor power, but it wasn't a permanent fix.

I've been troubleshooting this for over a year, and it's very possible this is just a poorly designed system. If you get to the root of it let me know, I've spent hours on attempting to troubleshoot with Dell but it's very difficult to replicate, because it only happens when the computer is under load/has been on for a while as far as I can tell. 

The best way to get it to show the issue is with a video game where it immediately starts driving heat and power, but even then it's tough to pin down. Sometimes it will work fine 100+fps then suddenly tank itself, only to resume a moment later. 

@dokasal​ i haven't gotten around to testing it much since I replaced the motherboard, and I got a slightly faulty one, but in some cases it seemed to work better, and now I'm sending it to Dell for a extensive repair

The 5570 may be a biggest hunk of overpriced JUNK Dell has ever produced. I had my 3rd motherboard replaced today? It has been nothing but trouble since day 1 and Dell doesn't care, because there enough fools like me who purchase this poor excuse for a reliable Laptop. No more when the warranty runs out, it goes to eBay and i plan to purchase a Lenovo. A little heavier but higher quality build and components.

I got precision 5570 at work and the laptop is junk. Overheating, lagging and not performing with just basic tasks. I dont want to see dell on my desk ever again. Looking forward to switch to another manufacturer in a few months.

@jan555444​ I've seen your identical comments about the Dell Precision 5570 all over YouTube, Reddit, and blogs. I'm convinced you're a bot that is misleading people. For anyone researching this laptop, please know that these comments are not trustworthy

@user_6fc4ec​ Not a Bot just someone who is on his 3 motherboard

in 28 months on a Precision 5570. Biggest hunk of electronics I have ever owned.  

@user_6fc4ec​ This is the only place I commented my dell experience. And my experience is real, maybe not all dells but my 5570 is really bad and I don't understand your motivation to question my words. You can share your experience but you know nothing about other people, so let them be. 

@jan555444​ My experience with my 5570 has been a nightmare as well. Not just the  2 motherboards and a hard drive failure, but performance as well have been terrible.
