Are you selling the whole Wii? Or just the Attaching portable bay?
Also, if the fan in your Wii is broke, why dont you send it into Nintendo? You should have got like a 3 month warranty when you bought the system. Also if you registered the system online, with your nintendo.com username, you get another 3 month warranty.
So thats 6 months. You got yours on november 19th, if you did you still have like 5 more days of warrannty left. Hurry and send it to nintendo
Also, if you didnt get a warranty, you can buy a Wii USB Attachment fan, that in my opinion works better than the built in wii fan. There's a few different models at uxcell.com.
Such as:

Also, if your wondering about uxcell's quality and shipping. They ship when they get the payment, and your item will come within like 4-8 days. Also. shipping on ANYTHING on they're website is $5. Doesn't matter if its BIG or small. $5 for shipping.
I have bought from them before, and theyre good.
Sorry if thats off topic. I just wanted to share.
