I'm personally worried about the GPU's heat harming the wires over time. I would've mounted it vertically, but I've never seen custom extensions that do that.
Might not be that bad. My computer picks up way less dust sitting on my desk surface than it did when I had it on the floor, and I imagine OP's TV is mounted at least as high as that.
You don't really need any airflow there. The only thing that gets hot there is memory, but that is already cooled through the PCB (good heat conductor because of the copper), which is cooled by the regular heat sink.
Adds about 1ns (nanosecond, a billionth of a second) per 30cm of riser. So essentially nothing. The only problem happens when some of the signals are lost / attenuated / confused due to interference. As long as it's a high quality shielded riser it'll be totally fine.
I am not fond of LTT so I won't link their video - but they did a 1.3m PCIE extension and measured no performance impact at all. I'm sure OP is fine.
Same. Been telling the algo on YT to ignore LTT related videos for awhile now. Used to get recommended like every other day or so. But lately the algo has been deprioritizing their vids. Maybe the latest controversy (employee abuse) had something to do with it
I'm curious about the effects of the added physical distance with a PCIe extension like that. Presumably it adds a tiny bit of latency across the wire. At what point does it become an issue?
it's only a problem if there's enough interference to prevent the card from linking at 16x with the pcie bus, otherwise lightspeed won't have measurable effects at that point, there's no processing done by the riser.
The latency isn't an issue, the timing becomes an issue because you don't have a clean signal at some point, meaning the signal will arrive "spread out" over time. If it spreads to the next signal, your GPU isn't recognized anymore.
But as long as.that doesn't happen, there is no latency or performance decrease.
May I ask why you went with mini-itx? There looks to be plenty of room for at least a micro-atx, which would probably be cheaper and have greater expandability. Great job anyhow.
Good question, it's mererly because I was using an ITX case with those hardwares, but it's not easy to fit the case behind the TV, so I came up with this solution. If I start new, I might choose ATX instead
this looks good, I have saved another peg board 3d print set and plan to do this eventually. I have the board and a printer, its just the time to mess around and try to mount it as its technically custom depending on your PC setup. Just not sure I can manage with the downtime whilst I fiddle with Starfield out and party animals later this month :D
