5000X Front panel causing frametime spikes

Recommended Posts


This is bizarre. Ok, for months I have had random frametime spikes in games that run smooth. The spike is a one off then back to normal and happens just a few times every ten mins or so.


Like so many others who have frametime issues, I tried all the fixes and even swapped some parts out, with no joy. Then yesterday I saw someone say to remove the USB 3 cable from the motherboard. Well, I thought "no way will that work" and yet it did.


Now it's not just my Corsair case as the person who told others to try this had a Phankeks case, so it's not just a Corsair thing and it cannot be on all cases as this would be well known. This leads me to think that it is a grounding issue with the front panel, but I am really not sure and not sure how to explain this to Corsair as the case is only a few months old. (don't see them admitting to any production faults)


Any had this before or know more about what causes it?

After speaking with others who mentioned that the USB HD audio can also cause issues, I removed that cable but it made no difference. It is only the USB 3 cable that causes the frametime spikes.


I did also try an Asus Z590 motherboard and as soon as I plugged the USB 3 cable in; the spikes came back. This at least ruled out the motherboard.


It looks like it is a grounding issue with the front panel, be it just mine or all of them.


The problem is most people who have a case that does this, will be trying every other fix there is and even swapping parts out like I did, not knowing that it's the USB 3, because let's face it, it's the last thing I would ever think of.


The original person who told me about this had a Phanteks case, so it's an issue that can appear on all makes, really, but I am just unsure if it's just my luck all the entire line?
