Scythe Ninja Plus Rev. B fan not spinning on startup.

[Craig321]

Hi,

Today I built my new PC (), but the CPU fan wouldn't start, so I turned it off and checked cables etc.

I then turned it back on & gave the fan a little push, after that it started.

Now whenever I turn the PC off and back on again I have to give the fan a push else it won't start.

Any ideas please? Should I be contacting the retailer for a new fan?

My other 120mm fans are working perfectly, so it's not a power problem.

Thanks,
Craig.

Might be normal.
My Mobo (see left) Has cpu fan speed controller so the cpu fan will not spin for a few minutes from start up unless i go straight into a game.
With such a big cooler it might take a long time for the cpu to get up to temp to run the fan.
If i web browse then it can take 5-6 minutes for the cpu to get up to temp to spin the fan, have an arctic freezer 7 on an as yet un-overclocked E6600, i was worried about it aswell but cheacked my temps and realised it's all fine. Ran up a game and a short time later it burst into life.

You might be right, but the problem with mine is the case speaker goes crazy when the fan isn't spinning. I'll try boot Windows and see if it eventually comes on... if so I'll just turn off fan warning

Thanks,

Sounds like a faulty fan to me.

[Craig321]

Just disabled auto fan control and tested again. It now kicks in every startup after about 2 seconds, so doesn't seem like it's a problem... I'll have to see how it goes

[TarnxTarn]

How did you connect the fan? power cable to MB (cpu fan socket)?

If yes...
Need to disable the fan control in bios.. those cool and quiet function... or if you use any cool n quiet sofware... uninstall it...

[Craig321]

I plugged it into the CPU fan socket.

I think thats normal, my ninja fan fires up once it gets to a certain temp.

[Clunk]

If it was normal, the bios would know that the fan isnt meant to be spinning, and it wouldnt do the alarm...wouldnt it?

[Craig321]

Very true Clunk, but as I said I'll monitor it... if it screws up again I'll tell Scan and hopefully they'll send a new one without me having to RMA.

Thanks,
Craig.
