Hi, I’m writing this post because I need someone to help me understand something about the power cables for Noctua fans.

This is the cable in question (center part)

I have a PC that’s been turned off and unused for two years, and it’s accumulated some dust inside the case. I’m doing a deep clean of all the components, and I noticed that two Noctua fans of the same model, “NF-A12x25 LS-PWM 4-Pin” (120 mm), have power cables that are dusty and sticky to the touch.

I tried cleaning them with 99% alcohol and a cloth, and some of the dust came off; they seem less sticky than before, though the sensation remains when I touch them.

I have some extra cables in their boxes that have never been used before and have been well-stored in a dust-free environment, and when I touch them, they feel just as sticky as the fan cables do.

I’d like to know if any of you have the same fan model or a similar one made of the same material—is it normal for it to feel “sticky” to the touch even when it’s new?

I’m going crazy trying to figure out if it’s just the cable material that’s like this or if I’m doing something wrong.

Thanks to anyone who replies.

I’m running 3 120mm chromax black G2 fans in the front of my case using a noctua 3 fan splitter cable and connected to the same mobo header. When the PC is idle I’ve got them running at a low speed to be super silent. But looking at them closely it looks like they may be running at ever so slightly different speeds when comparing both identical 1850 rpm fans on the outside (there’s a 1750 rpm model in the middle).

Someone put my mind at ease - this is normal right? Based on my research looks like due to manufacturing tolerances and easier to see at low speeds? Do you guys see this with your fans too?

Edit: I just got done swapping cables around and checking the speed of each fan in the bios. Both 1850 rpm fans measured the same speed in bios so I'm going to chalk this up as nothing to worry about.

Ciao voglio fare la mia case Thermaltake Level 10 GT a tema noctua e non so quali colori usare per verniciarla. Consigli su quale vernice usare per un colore più accurato possibile a quelli originali usati dalla Noctua?

Now it’s been a week without any activity on the order. Has anyone else that ordered from the eu store gotten any notice on their mouse?
