SOLVED 3pin Fans To 2 Pin (3 Wide) Female Connector Safe?

In my CM Storm Scout case, I replaced the weak fans on the front and top of the case; my rear fan slot is occupied by my H70. With the top fan, I have it connected directly to my PSU via a 2 pin (but 3 slotted female connector) but my fan is 3 pins. I've run out of space on my mobo because my CPU waterblock on the h70 use 30 pins as well instead of 4 like typical CPU coolers.

Is it safe to leave my 3pin fan hooked up to this 2 pin converter without causing PSU or fan problems (fire or destroying)?

This is the fan I'm using http://www.microcenter.com/single_product_results.phtml?product_id=0310672

and this is the connector I'm using to connect it directly to the mobo

So are you wanting to use a converter to connect more than one fan to the motherboard?

If so, make sure the combined amperage is less than 1 amp, as that's all that most motherboard headers will take... if you need RPM sensing to work, cut the yellow wire on two of the fans, so that there's only one yellow wire going to the mobo.

Why not just plug them into the PSU directly?

This can vary substantially. You should check your motherboard's manual for specifics.

I've killed a CPU fan header with a low speed 120mm fan. On my server, I'm running two ultra high speed Delta fans (high power draw) off a single fan header. It varies too much to make a "1 amp" blanket statement.

wait I think you guys have misunderstood me.

I'm using that 2000RPM fan connected directly to my PSU via a 3 to 2 pin (female) adapter

Is it safe to run even though the female adapter doesn't have 3 spokes?

Yes. The third pin is an RPM sensor and has nothing to do with the fan actually running.
