    Makes you wonder why nobody in the high-end case market hasn't already used PCI-E risers included in the price to provide a creative and vastly more efficient mounting position for the GPU...
    I mean, screw vertical mounts to show off your bling... What you want is your GPU fan intake directly stuck onto an intake - or better yet, just a separate compartment at the bottom or top where you can both get direct access to fresh air AND vent all the heat right outside the case to make cooling the chassis trivially easy.
    Of course, nothing is really stopping you from just doing this yourself. It would be easy to use a riser from a lower slot down to any case with a bottom intake - or you could go full ghetto and just let it sit outside your case if you just don't care :D probably well worth the cost in terms of cooling benefits over lots more casefans, watercooling or very expensive models with overengineered coolers.

    This needs to be retested with pcie 4.0


    I'm using the exact same riser now. It's a little longer than I needed so I was concerned but I actually got better benchmarks after installing it.

    `Yeah, this makes sense. signal loss due to the connectors and copper. however; a properly made cable would probably still go further. IBM had this issue like 30+ years ago with cable runs to the Disk storage on their 'System/38' mini-frames (not quite main main frame class) we are talking 30 ft distances, and entire room distances. Their solution? 5mm coax (one for each signal line) platinum cables.

    How do I know? I scavenged some of those bundled drive cables (about 1" around) and repurposed them as video cables. - new ends on a couple and 30ft+ later I still have no discernible issues with signal problems. Now even tested to 1080i standards too.

    I had two of these cables - looked like this:

    They were the bus cables that connected the main system to the 'exterhnal' enclosures teh drive stacks were housed.

    Yes, I cut my professional teeth on this machine - from operations to programming in RPGIII.

    good to know, I need to get one of these to move my parts from one case to the other, but it already has a riser from a SFF case that uses m.2 nvme drive on it and the GPU, and it will make it sideways in the case not attached to the case, so this is exactly what I needed to make it fit into the new case! Instant buying tomorrow!

    Quick question about the power supply. I need to power a gpu with its own power supply similar to what you've done in the video, but the Rosewill 550w PSU I've purchased claims that it will not power on if it's not connected to a motherboard. Has that been your experience, and is this an issue that is specific to certain types/brands of PSU? Any help is appreciated.

    I wonder if it failed because of the length of the cable, or because they laid the card face down on a solid surface, cutting off all of the airflow?

    Of course the Titan would be capable of a longer length. It's power regulation on inputs and outputs is probably much better than the cheaper cards. Plus plenty more connectors to ground vs only through pcie.
