Hi everyone, I've recently started having an issue with a build I did a couple of months ago. I'll preface this by saying that I was originally using 3-pin splitters on all fans but the cpu fans then the problem changed slightly when I switched to 4-pin splitters. The fans I use are 2 corsair SP120s and 3 corasir HD120s, along with 2 CPU fans.
After using the BIOS Qfan optimisation (ASUS Z270H mobo) my computer started failing to POST, only the CPU fans would run and while the LEDs lit up on the chassis fans, they would not run. I tried pushing them slightly to get them running but no joy. After restarting the computer a few times by turning it off at the wall it would eventually boot normally with all fans running. Now that I've switched to different splitters I'm only having this issue with the non PWM SP120 fans. I still have to do multiple restarts every time I want to turn my computer on to get the fan running so the computer can boot. It is also having this issue when I try to wake it from sleep.
I have also tried using AI suite 3 to change fan settings and I've gone back and forth multiple times resetting and reoptimising to the point of madness. Could it be a voltage issue to the SP120s? If so please could someone help me work out how to fix it?
