Hi @PingwinVonJelen, I tried that with my Zbook 15 G2 and it didn't work. I couldn't start the laptop. You might try if you have option to return it. @Mashcar you also could dremel out the plastic fragment between DVD bay and HDD bay for extra space and even place a fan with two air output [like big brother 8770w. It has air output from left and behind]. But you could use only mSATA for storage.

Not big upgrade but Zbook 17 G1/G2 is capeable to fit 3x 2.5 HDD (2 in HDD bay + 1 in DVD bay with adapter). Haswell, up to i7-4940MX. Zbook 17 G1 also has bootable mSATA slot. Zbook 17 G2 has M.2 slot but there are problems with booting. Don't know what is the maximum drive size supported by Zbook 17 Maybe Zbook 17 G1 with DVD>HDD and mSATA>M.2 adapter is good option. Should be also lighter than your Alienware. 1xSATA to 2xM.2 adapter is also nice thing if you consider switch to M.2

Hi, please check PM for schematics. I don't know if they are 100% accurate. M4000M - idle about 60*C - didn't test it for long time because I bought Zbook 17 few days later. Fan spinning a lot! Don't remember temps for K4100M. I already passed Zbook 15 to my parents. Could you be more precise about muxxer? What do you mean. I am not a technician nor engineer, just basic IT school and hobbyst. About TB to NVMe mod. Didn't know about it. Don't know if I will do it. To be honest SATA SSD speed is really enough for me, for daily use and gaming. I have a list of games from 2000 to 2023 that I always wanted to play but never could. ATM I am at 2002 and before I reach "modern" games that require more than M4000M (GTX 970M) it may take a while. Maybe I will be able to get some Pascal GPU or even some RTX. I don't like excessive fan noise while gaming, I also can't play with headphones on because of small baby (I play when baby is sleeping). Now I manually control fan with app "notebook fan control" so I can adjust fan speed and get ballance between noise and temp. I have some new mods in my head but I am very limited with time. I like few mods of this guy https://hardwarebg.com/forum/showthread.php/291904-GTX-1070-на-HP-EliteBook-8770W-дядото-още-го-може-)

Hello, I just wanted to share my experience with HP Zbook. First 15 G2 and later 17 G1. So I bought a cheap Zbook 15 G2 with a crappy FHD TN screen, K1100M and not so bad i7-4710QM. Later somehow I found a topic on notebookreview: “8560w GPU upgrade - use empty DVD slot to fit MXM 3.0b (higher spec) video cards”. Turned out that Zbook 15 G2 has a similar motherboard to Elitebook 8560w/8570w and mod is also possible. So I purchased a used MXM B card: Nvidia Quadro K4100M 4GB. Followed the guide and everything worked fine. I also managed to buy a Zbook 17 heatsink and desolder it for the Zbook 15. Everything worked fine until the card died. I decided to purchase a Nvidia Quadro M4000M 4GB. Did some dremel work, INF mod and everything worked fine. Turned out that the M4000M (GTX970M) is hotter than the K4100M (GTX770M) so I decided to add another heatsink. Few days later somebody was selling a dead Zbook 17 G1 with a Dreamcolor screen for 70€, so I bought it. Used motherboard was like 50€. Bought the board and replaced it. Laptop was still dead. When I unplugged LCD cable both motherboards worked on the external display . I assumed that Dreamcolor LCD is faulty and started searching for replacement on panellook but wasn’t satisfied with the results. All “good” LCD panels are eDP not LVDS, so I started digging. Zbook 15 has eDP LCDs and Zbook 17 has LVDS LCDs but the connector physically is the same. I downloaded schematics for 15 and 17 and the connector pinout is the same. Connected display+cable from 15 to 17 and it worked. Bought a nice used eDP 30 pin panel from Dell Precision 7750(?) Innolux N173HCE-E3B (100% sRGB, 100% DCIP, 90% AdobeRGB, perfect angles, 500nit). Now I know that everything works fine. I cut out some plastic parts from the LCD cover, added 5mm plastic foam bought in an art store + two-sided tape + a little bit of shaping and voila! Modern LCD in a 10 years old laptop. Extra thoughts about this mod: Cable length from Zbook 15 is enough for Zbook 17 G1 and G2. Didn’t test it but the Zbook 15 G2 had an option for QHD+ (3200x1800px 60Hz) 40 pin LCD and cable. It’s DisplayPort 1.2 - HBR2 17.28 Gbit/s so it should be possible to upgrade for: 1080p up to 240Hz, 1440p up to 165Hz or 4K up to 75Hz. For my casual retro gaming 1080p 60Hz is enough so I didn’t search for hi-res hi-refresh rate panel. I also prefer better colors and viewing angles than higher refresh rate. When you try to adjust the brightness Fn+F9/F10 there is a 3 seconds delay between each dimming. [Windows 8.1]. Screen brightness [slider] from “Power options” forks fine - no delay.

Extra heatsink is from Dell Precision M4500. + no heatpipes bending is needed. - no direct connection copper to copper = poor efficiency I also changed cpu heatsink to dual-pipe heatsink from Zbook 17 G2. Not in the photo.

Hey, I meant this fan, please check picture, numer 2. Does it spin like that without body? (I dont know how to describe it) Also where did you get gpu heatsink 1 in the picture. I was thinking about to put ODD BAY SLI GPU from Lenovo y510p because it fits perfectly in DVD bay, just do some work with extra heatpipes

Hello @Mashcar great job with your Elitebook! I want to reproduce your heatsink work for future GPU upgrades. Could you please tell me what technique did you use to solder heatpipes? (I know low melting point solder is required) Was it heatgun, compact electric oven or just full-size kitchen electric oven?? I don't feel comfortable thinking something could explode right in my face :) Edit: Do you keep the 2nd fan without "case"?
