    I found the problem. The main problem was the GPU vent. It was blocked by a thin layer of dust from inside. I found that out when I noticed the air flow from CPU vent was much better than GPU vent, like 5 times better. GPU vent was barely working. I had to take out the fan to totally clean it. I also had a chance to clean the VGA chips and CPU top by alcohol. I applied IC Diamond thermal paste on both CPU and GPU and Aikenuo thermal pads on GPU chips.
    I contacted the person who sold me the card and asked for the make and model of the laptop that this card belonged to. It was a MSI GT72S 6QE Dominator Pro. I found the actual NVIDIA driver for that laptop and installed that.
    I run all tests on the main panel, without any additional monitors. GPU never went over 75C and never throttled. CPU temp was also dropped by 10C.

    I'M SO HAPPY NOW :D

    Nice work, and good find on your blocked vent. Sounds like you're ready to rock and roll now. :)

    @TenGauge kinda off topic, but you're the first person that popped into my head for this. I was offered a pretty good price on a 3940XM and I'm considering upgrading from my 3920XM, but I'm kinda hesitant, mainly due to this comparison I saw on UserBenchmark showing the 3920XM actually outperform the 3940XM in various categories (http://cpu.userbenchmark.com/Compare/Intel-Core-i7-3940XM-vs-Intel-Core-i7-3920XM/m7092vsm5061). Did you happen to have a 3920XM before? Or do you know/have you heard anything about this before?

    See:
    https://www.cpubenchmark.net/compare.php?cmp[]=901&cmp[]=1482

    Unless the 'pretty good price' for the 3940XM was in the range of 'free' or, we'll pay you $50 to take it, I wouldn't be considering this swap in a working system. ;)

    Both are good CPU's for their time (circa 2012, 55W TDP units...). Keep enjoying what you have. The grass isn't greener on the '40XM side (as you've linked).

    Was inspired by your post to take apart my laptop again. God damn you were on to something. The area inside the fan behind the vents are a . . . the term "dust magnet" doesn't even begin to cover it. I took everything out and scrubbed the vents with a brush under running water before drying it and putting everything back together. I just booted up so I haven't had time to test temps yet but I can already feel way more air going through than normal. It was a good opportunity to redo my thermal paste as well (I don't think I used enough last time). Time to see how this runs.

    EDIT: got me thinking though. can anyone think of an easier way to clean that out regularly, cuz opening this up to do that is a PITA, and that's bound to get dirty and dust filled on a pretty regular basis.

    Didn't run any benchmarks or anything but left my system on for a while, and played some league. I'm idling like 17 degrees cooler now at 51. Temps during game were much lower than usual too. I'm happy.

    EDIT: this is docked with my 3x 2560x1440 144Hz and 1x 1920x1080 60Hz displays connected btw. Previously this setup was idling closer to 68 degrees. Haven't tested undocked yet.

    @TenGauge. Do you know if the dreamcolor panel has a 40 pin connector (not the color board). I may be able to get a dreamcolor panel on here for around $200 it looks like if these are what I think they are. If I search ebay for the part number of the dreamcolor panel itself (not the assembly), which is 688736-001, I get a ton of results for 40-pin LG panels (and I know the dreamcolor display is an LG one): https://www.ebay.com/sch/i.html?_from=R40&_sacat=0&_nkw=688736-001&_sop=15

    I had to go to a few other sites to find this, but searching for the part number of the color board (which took me a while to find), 652686-001, yielded some results as well. The best I could find was http://www.radwell.com/en-US/Buy/HEWLETT PACKARD COMPUTER/HEWLETT PACKARD COMPUTER/652686-001

    It would add up to about $180 if these are in fact the right parts, which is my main concern. Are you able to check this at all?

    Thanks

    The DC panel is a 50 pin connector to the color board and then the color board to the motherboard is the standard 40 pin connector. The hardware ID for the DC panel is LGD02FC. This should be the proper panel here: https://www.ebay.com/itm/New-17-3-L...HD-1920-1080-LP173WF3-SLB3-50pin/253117932455

    This would be the color board if you can find one: https://www.terapeak.com/worth/hp-e...cable-6050a2422501-6017b0299301/361805040584/

    Thanks for the info. does the color board also convert the lvds signal to an edp signal? I thought that ebay post looked familiar, and it's because it uses the exact same image as this other post (https://www.ebay.com/itm/17-3-LED-L...137364&hash=item4b23498290:g:z7EAAOSwKBVZrj4-) labeled for a 17" zbook G2, which I know uses eDP.

    Yes, I believe it does.
