Second chasis fan not working?

[Shockwave1000001]

Hi,

 

I got a Asus PRIME Z390M-PLUS and I'm using these two fans:

and

What I don't understand is the first link fan works fine no matter the configuration but the second fan doesn't. I didn't realise that the two fans I purchase were different and so now I got two because I thought one was faulty.

 

I bought a fan splitter thinkning it would work but it doesn't. I do have a adapter na-rc7 which I could connect it to the second fan then to the fan splitter with the 2 pins or 4 pins. Would that work? Or is it dodgy?

I think the one may be faulty. I'd exchange it and try not go with such a dodgy setup.

Test each fan on a known working fan header of the motherboard.  If one of them doesn't work, return it.

Are they connected directly to motherboard? Is the regular F12 4pin or 3pin? AFAIK they come with both options (and Arctics site doesn't load atm).

I can't imagine two fans to be faulty. They're both 3 pin and it says on Amazon that it can work with a 4 pin. Is it the motherboard that doesn't accept 3 pins and only 4? I messed around with BIOS but I stil can't get the second fan to run when its connected.

If that fan doesn't run when connected directly to mobo, then its faulty.

 

3pins can be used on 4pin headers, thats not the issue. The reason I was asking was because you mentioned splitter. 4pin and 3pin fans can't be mixed in a splitter. Though even then they would work.

Without the splitter it doesn't work. I'll try and go to a PC shop and test them.

 

These is what I'm using:

I've taken my Arctic F12 Silent fan to some PC place and it works fine when tested into a 3-2pin. I don't get why it wont work with a 4pin on the motherboard or fan splitter when my old 4pin fan does work.

Okok, I'm very boba. I got the fan pins wrong here.

 

The old fan is a 3pin and the new ones are too. So why are the newer 3 pins not working when I connect them directly to the motherboard that has a 4pin?

 

The only difference is the old fan is different coloured cables whereas the new one are all black.

Its most likely just DOA fan if one of them works and another doesn't. Nothing more than that.

I've found the issue. I connected the two new fans to a splitter and they work fine without the front panel on, but if I put the front panel back on then only one fan works. It looks like the front panel wires or whatever is there are interferring with the top fan to work. Maybe some magnetic interference or what. For now I'm just running one fan seeing as I can't close the panel without the top one working.

 

Or a wire is pushing against the fan hard enough to stop it? xd
