Buy this link you will get all 4 fan, use for W1070+ W1080ST+ HT1075 HT1085ST ONLY.

The 4 fan may have different version and some of them are used one, some of them are new one.

anyway, I will test them before send out. Make sure them working perfect.

beware:

if you need W1070 W1080ST fan, choose my other link, without "+" is different model. (there is 1 small fan connector is different, other 3 fan is same)
