Why shouldn't you use the IFX-14 with a Gigabyte 965P-DS3 ? , I read the review so excuse me if it says why but somehow i've managed to miss it if it does.

For those that don't overclock which would be quieter due to fin density the IFX-14 with a 500rpm 140mm fan or the Orochi with it's stock 140mm 500rpm fan ?

Thanks
