Question Can a faulty SATA cable cause RGB fans to flicker and affect performance?

This is gonna be long so please bear with me.

So I bought my system 2 years ago and after a week of use, the rgb lights of my case fans started to randomly flicker and noticed it only happens when system is under heavy load (when running games and benchmark).

Also noticed that when the rgb lights starts to flicker, game and benchmark performance also randomly drops hard. I obviously returned it to get it fixed/replaced and the store just replaced the rgb fan hub. After that, it seemed to fix the issue.

After 1 year of no issues, it started to happen again; rgb fans started to flicker on heavy load with random performance drops.

I have 3 drives - an nvme, an sdd sata, and an hdd. I noticed the issue seems to happen more consistently when I'm using heavy load programs or games installed on the HDD (the issue also happens when using programs and games installed on other drives but quite randomly, usually when it's on consistent heavy load for a long time).

So I started to narrow down the problem with with my HDD. I tried playing demanding games installed on it and I noticed the slow loading times along with the said issues. First thing I tried is to replace the SATA cable connecting the HDD to the motherboad. To my surprise, it fixed all the problems.

But after another year of use with no issues, it started to happen again when I was playing a game installed on my other drive (SATA SDD) while recording using OBS (installed on my HDD).

I immediately ran Kombustor's 1080p preset benchmark (installed on my HDD) and the fans immediately started to flicker and saw some fps drops (consistently running 60 fps as usual then randomly drops to 12 fps a few times while running the benchmark). Also tried running a game installed on the HDD and noticed the very slow loading times.

At this point, I figured the SATA cable for my HDD is faulty again (they're dirt cheap) but I don't have any extra SATA cables lying around this time so I tried removing and reinserting the SATA cable from my HDD and motherboard but inserted it to a different SATA data port available and suddenly everything's running normally again. I ran crystaldiskmark on my HDD just to check if it's actually the one causing the issues but the results seems normal.

It's been 4 days and everything seems totally fine. Been running Kombustor and crystaldiskmark on my HDD randomly and playing games while recording and so far issues are not reoccuring. As if nothing happened.

So I just want to ask what you all think about this?

What's really causing the RGB of my fans to flicker and my performance to drop hard randomly? Seems like a power delivery issue but my power supply seems fine. I have not experienced any other issues related to power or any other issues at all besides the issue stated since I got this system.

Can a faulty SATA cable cause all of this? Or maybe the SATA data port of my motherboard is faulty?

Could it be that just removing and inserting back my SATA cable connection is the actual solution to all of this? Just like when we reinsert our RAM sticks when experiencing RAM related issues?

I have not yet tested to reinsert the SATA cable of my HDD to where it was originally inserted on the motherboard before the issue reoccured recently just to check if maybe that specific data port is the one that's faulty.

But if that particular data port is the one really causing the issues, why did it suddenly got fixed when the store replaced the fan hub 2 years ago and when I replaced the SATA cable using the same data port 1 year ago?

Would also like to point out that when I returned it to the store 2 years ago when the issue occured for the first time, I removed my drives (SSD & HDD) because I didn't buy those drives from their store and when they tested it with only the nvme installed, they've managed to replicate the issue so we were all convinced that the fan hub was the one causing the problem because once they replaced it, everything was fine for a whole year.

Weird right?
