Basicly 1 in 20 boots or so, one of my fans wont be spinning and I have to shut down the computer and turn it on again and then the fan spins again. Computer specs:
 

  • CPU: I7 3770k
  • Cooler: Noctua NH-U12S with NF-F12 Fan
  • Motherboard: MSI Z77A-G41 Socket 1155 HDMI VGA LAN 8-channel audio ATX Motherboard
  • GPU: GTX 970
  • Ram: G. Skill Ripjaws-X DDR3 240-Pin 2133 MHz 4x 4GB (F3-17000CL9D-8GBXM) (OC to 2133Mhz)
  • SSD: LITE-ON LCT-256M3S 256GB SSD 2.5" SATA III 6Gbps
  • HDD 1: Western Digital 2TB SATA 6Gbps Power Saving Internal Hard Drive OEM - Caviar Green (WD20EARX)
  • HDD 2: Western Digital 500b (WD500AADS)
  • PSU: OCZ ModXStream Pro 600W Modular PSU -135mm Fan
  • Back Fan: Noctua NF-F12 PWM Fan - 120mm
  • Front Fans: NF-A14 PWM Fan - 140mm x2

Normaly it only the back fan, that does not turn on but have had it with one of the front fans not coming on, for the front fans I use a 2 fans to 1 connector lead which came in the box with the Noctua fan, for the back one I use a extension which came with the Noctua box as well.

 

My thoughts are prehaps it the PSU cant handle all the parts which i dont think likely as it should be useing less then 600w, the 2 to 1 connector or the extension lead are making problems. Anyone have any thought to what it could be?

your psu has PLENTY of power, i bet it doesnt even draw more than 450W under full load. my questions to you are simple ones but i hope that they lead to a possible solution anyway.

 

  1. how old are these fans
  2. how dirty are these fans
  3. if you spin them with your finger do they start spinning
  4. have they ever simply stopped after spinning for a while
  5. do you have them tied directly to your PSU or through a fan controler
  6. have you made sure all the power connections are solid and complete

You can also try cleaning the connectors using something like CRC56, my speakers from a long time ago (I did a post on here) had the same issues, one of the speakers channels wasn't working and using CRC56 on the connectors/plugs fixed the issue.

It most likely sounds like a bearing issue with the Fan or it could be something simpler such a connector like WaveZero mentioned.

Try cleaning the connector using some electrical contact spray from the WD40 Specialist line or any other similar product. If its a bearing the fan would mostly need to be replaced.
