Faulty caldigit active cable or bad setup?

For my EGPU setup I'm using the Aorus gaming box RTX 2070 with the H2D firmware installed, an X1 Carbon 6th gen (i7-8550u, 16 GB ram, 1440p non-HDR panel) and a Caldigit TS3+ dock for various peripherals. I don't currently have the space for an external monitor so I am using the internal monitor for gaming. I have been using this setup for about 2 months now without issue, aside from initial setup. 

Normally I can connect the EGPU and the dock to the two thunderbolt 3 ports on my laptop, using the provided (presumably passive) 0.5m and the 0.7m cables (respectively). However I did want to buy a Caldigit active TB3 cable just so I can move the EGPU further away for better airflow since my desk is rather cramped. 

When using the Caldigit active cable for the EGPU it initially worked as intended for about 30 minutes - 1 hour before suddenly disconnecting the EGPU and bluescreening my laptop. This became a pattern for about 5 bluescreens before I gave up. I then tried using the EGPU alone and connecting my mouse using bluetooth but the pattern continued. Went back to using the 0.5m cable and saw no issues. I then used the 2m cable for my TS3+ dock which surprisingly worked for well over 2 hours without disconnecting my dock, until I disconnected the cable from the laptop. After reconnecting the 2m cable the dock's LED would erratically flash like I was disconnecting and reconnecting the cable over and over.

Before I send this cable back to amazon is there anything I should know/am missing/should try? Any other recommendations for 2m active TB3 cables?

Hey @krismatic, you may have already returned the TB3 active cable. My two cents is that it warrants a return. I started experiencing issues with my Aorus Gaming Box (RTX 2070 model) side fans after the FW 1.3 update. One of my tests was to get a new active TB3 cable and I did notice a difference.

*eGPU now connects right away without multiple errors
*monitor is always full brightness (using the old cable, the laptop would sometimes wake from sleep with the brightness of the external monitor completely dim)

I ordered a Mantiz made model on Amazon. With those two observations above, I suspect that my old active TB3 cable did have issues. You may as well take advantage of Amazon's policy and get another cable. You will either get better performance or rule out that you had a bad cable.

From your side, can you let me know how your side fans behave? Ever since my FW 1.3 update, my side fans no longer spin up. I even tried another engineering student's Aorus Gaming Box (RTX 2070 model) and his stock unit would also fail to spin up.

For the most part I haven't really noticed any changes after initial setup mostly cause I'm still using the H2D firmware from January, never cared enough about noise to try the 1.3 firmware since I have noise cancelling headphones. Fans still spin like normal and get louder if I play something more intensive but honestly my desk fan is louder than the EGPU.

The only note worthy thing I can say about the fans on mine is that they'll spin very slowly if the laptop is still detecting the EGPU but they'll spin back up once everything is detected and the RBG lights up at the same time too.
