XFX 8800GT onboard fan connector

I've got a Thermalright HR-03 GT which I must get around to putting on my graphics card, which is an XFX 8800GT. I've also got a Scythe 92mm PWM fan to sit on the HR-03 GT.

The plan was to power the 92mm from the graphics card so that it retains it's variable, temperature-dependent speed. However upon closer inspection, the 4-pin fan connector on my gfx card is smaller than the standard 4-pin PWM connector on the fan.

Does anyone know what this onboard smaller PWM connector is actually called (so I know what to search or look for), or even if it's a proper standard, or whether converting connectors are available?

I can always run the 92mm fan from the mobo, or even molex, but then it wouldn't be temperature dependent.

Thanks in advance. :)

I think you'll find with the HR-03GT is so good that its fine on a single speed low rpm fan.
