Comment: What is the best way to connect fans as the 2 new fans i bought have a normal psu connection and a connection that fits on the motherboard..
I know i dont fit both these at the same time its one or the other (correct me if im wrong) but which is best i only have one connection on my mobo so what i was going to do was fit one here and the other onto the psu connection.
or do i get an adapter and fit both fans onto the mobo.
what would you guys do i have 2 fans to fit

Reply: (edit)I am running a P4 2.8 and have 4 fans connected to the PSU, and one to the mobo. The side panel fan is connected to the mobo while the two front and two back are connected to the PSU. No problems with cooling.

Reply: (edit)The only advantage to conecting a fan to the motherboard is that you can use software to tell how fast its spinning (RPM)

Reply: (edit)Yeah, you only need to connect it to the mobo if you want to monitor its fan speed, or possibly have the mobo control the fan speed. Some mobos, like the intel mobo on my other computer, has multiple fan connectors (mine had 3), but will only monitor one of those connectors (mine was fan #2 I think). In those cases, the mobo's fan connector is only to provide power to the fans that have only one type of connection available (I have a couple of fans that can't be plugged to the PSU)

Reply: (edit)I would agree to everything above except when it comes to the CPU fan. Some BIOS monitor the CPU fan speed through the motherboard connection. If there is no fan plugged in it will assume tha fan has stopped and shut down the PC. So its best to have the CPU fan monitored if nothing else. A failed CPU fan will destroy the CPU in very short time. Stuart

Reply: (edit)Do not connect both to the motherboard connection. It could draw too much current and damage the motherboard.

Reply: (edit)Stuart gives good advice, if you only have one conector on the mobo for a fan, use it for the CPU fan.

Reply: (edit)the cpu fan is already connected to the mobo im not talking about this one. what i have is 2 other fans that i want to put in my computer
I have one spare connection on my mobo so do i put one on mobo and one on psu or is it best to put them both on psu as i wont be checking speed of these..
if i have to put them both on psu do i just get a y splitter (will this be able to run 2 fans no problem)

Reply: (edit)one on the psu and one on the mobo is fine and it doesn't matter which is which. If you have the connectors for it, put both on the psu just to keep the mobo from playing middleman. But it really doesn't matter.
