Fans doing something odd?

post #1 of 20
Thread Starter 
Hey guys I have 8 of these. I ran into a problem. I fired up the rig and only 4 are spinning at full speed, and the rest are like spinning and stopping, spinning and stopping. All new fans so I assume they are all good? i have never ran into this before. I have this PSU. I assume it has enough juice to run all the fans? Any tips, tricks advice would be great!

How have you got your case fans hooked up? fanbus? series wired?

Just wired right to the molex connectors. I had a fan controller but I have it sitting the box.

That shouldn't be happening if they're all hooked directly up to the PSU.

And yes, some fans can come DOA.

Seems unlikely you'd get 4 bad ones in a bunch of 8. Have you got all 8 daisy chained of 1 molex? Maybe a bad connection on one of the passthroughs? I'd try each one seperately.

I don't mean to hijack the OP's thread, but does daisy chaining mean using the female molex of the first fan (which is connected to the PSU) to connect the other fans?

Yes, I agree with him, try what he said. A few may be DOA. Although it doesn't seem likely maybe your PSU doesn't have enough power, I'm not sure how much wattage it can sustain continually, many companies put peak output on, and I haven't really heard much about InWin. If your PSU is old it may also be deteriorating producing less power. Try what Darren9 said first before worrying about DOA and PSU problems.

Yes I believe so, or whatever the fan connectors 3 pin to molex is then continuing using same pathway to PSU

Yep, so if there's a fault between the male-female on one of the fans it would effect any others connected after it.

If daisy chaining is the case, maybe even if it isn't then I guess checking the fans one by one by plugging it directly to the PSU (a jump-started one would be faster) would be necessary
