Which cooling fan should be used for a 39T5451 motherboard?

[linuxthinkpadfan]

I've bought a replacement motherboard for my T42 (motherboard part [39T5451). It has an ATI Mobility Radeon 9600 GPU under an aluminum heatspreader. The cpu cooling fan assembly from my kaput motherboard is a "short" cooling fan that doesn't cool the GPU. Can I safely use it for this motherboard and GPU? Or, do I need the "long" cooling fan assembly?

Thanks very much for your advice!

You definitely need the long one.

Yes, we have many T42's and T42p's at our house, all with 9600 and fireGL, and all of them need a long fan.
