I ran an open case system for a long time with just a single fan on the CPU. Through iterations of that system I even had the fan plugged into an external outlet and not run through the PSU at all. I recently bought a "gamer" case with three fans in the front and one in the back to see if this excessive airflow would be good for my 7800xt.
No matter what configuration I connect the fans with whether it's each fan connected to an individual molex connector by itself or all fans connected to a single fan controller going to one molex power connecter, mouse movement is WAY heavier with all these fans connected. I will now be heading back to my single fan setup and will probably even power it externally bypassing the PSU.
Forget the people talking about EMF from radioactive pipes in the walls or UFOs, if you have heavy cursor movement (since it seems like a lot of you run an insanely high amount of fans) this is probably your main problem. As to why this issue occurs, can't tell you. Either the fans generate a field while running and feed noise into the PSU or maybe some PSUs just don't handle being pulled on by numerous small devices at once. I have a platinum Corsair (Great Wall OEM but it scores God-like in tests better than just about anything), so this phenomenon will probably be noticeable on many other (all?) PSUs.

I can confirm that every professional, when it came to playing the LAN disassembly case and reconnecting the fans, I saw that myself.

Hey, r0ach, glad to see you here.
Your threads on OCN basically founded the tweak community.
About your finding, for anyone interested in this issue regarding fans/molex, there is an almost 10 year old thread on OCN discussing it: https://www.overclock.net/threads/after ... em.1524063

The fan issue is kind of a complex subject. On my setup it feels like each additional fan brings an additive effect to creating heavier cursor movement (and maybe some types of fans are worse than others - no idea yet). If someone prefers heavier cursor movement for aim they might not see this as a problem. I could see people removing four fans from their PSU and noticing mouse movement feels 1/10th as heavy and actually playing worse.andreeeeee- wrote: β15 Jan 2024, 18:31Hey, r0ach, glad to see you here.

Some people hit the lottery on their builds and it just winds up ideal for their aim with the random parts they bought. For other people, you have to add or remove components if something is causing a problem. For my current setup, I run 7800xt with modded/stripped AMD drivers installed via driver only mode. Mouse movement is more sensitive than any Nvidia drivers released in the last several years. With the combination of removing all the fans + the stripped AMD drivers, I play better at 1440p because it's actually overly quick/sensitive at 1080p.
So as you can see, depending on your preference for heavier or light cursor movement and each person's hardware variables, issues like this are going to range from no problem to enormous problem for some people. Having four fans plugged in feels overly heavy for me with any combination of variables, though.
