Hey guys
I just bought myself some new components and put them in my old computer case, the computer was an hp a6024.fr, and it had an extra fan (like all desktops I imagine), which I have removed from the case to insert the new motherboard more easily. Now I want to connect it to the new motherboard, but I couldn't find its connector. The manual doesn't show where that is. The motherboard is a certain Vtech H61 mainboard, and after connecting everything I want to know should I connect the fan and how should that be done (the cable attached to the fan has a 3-pin end, which I don't know where to connect. Any help ?
I did read the manual, and I found a "sys-fan" connector but on the motherboard there aren't any pins there to go into the fan connector, also it's far from the fan's place and they are separated by the graphics card. The fan cable isn't that long. Is it safe to work without the fan (i3-2120 + 4gb ddr3 + msi gts450 + aopen 500w) ??

The fan was probably connected to a fan "header" on your old motherboard.

Motherboards generally have at least one CPU fan header and one system fan header. (Header = connection point)

Beyond that different motherboards have different quantities of these connections.

If you have your CPU fan and chassis fan each connected to their own connector on the motherboard and have no remaining open connectors, the solution would be to use a fan splitter.

Assuming both fans are 3-pin fans:

Connect the chassis fan to the connector with 3 wires and the extra fan to the connector with only 2 wires. That way your main fan is the one the motherboard sees and adjusts while your extra fan just gets whatever voltage the the motherboard sends to the main fan.

Actually I don't have two fans. I have a cpu heatsink connected and working, and only one other fan, but the motherboard doesn't have the header, it's been removed. What do I do ? Please help !

Are you saying the pins are broken for the connector at the motherboard?

Another option would be a molex adapter that allows you to connect a fan to one of the power supply connectors. THis will work fine, but your fan will run full speed all the time.

There are also manual fan controllers that would allow you to set the fan speed.
