My Dell Demension Desktop B110 Model has a fan bellow the power supply fan motor. That so called fan that I'm speaking of so happens to cool the processor, through a funnel type housing that goes around the cooling fan,on the inside of the desktop housing case. The fan was made by the Minebea Co, LTD. NMB D1598 are in the middle of the top of the fan on a sticker. How can I purchase a new fan, so that my desktop will be functional again. It was runnig windows xp. I wanna put a new fan, and install Windows 7 on it. If anyone knows how I can purchase a fan, please feel free to send me an e-mail @ [email protected] .

That fan is a standard 12volt muffin fan. You just need to go to any computer shop or electronics store and they will have a generic replacement that will fit. The only thing you need to watch for is that the replacement is as thick. If it is too thick (unlikly) the duct will hit and the case won't close. Too thinand the fan will pull in hot air from the case as well as cool air. There is only one connection for power. And there will be 4 screws. Replacement cost should be around $4-$10 That fan is a standard 12volt muffin fan.
