CPU fan has high failure rate. I have ordered the fan 4 times. Orders numbers one and two cancelled order number 3 they sent the wrong part order number four cancelled - then "reauthorized" still do not have the part - can not get an after market propeitary part. Used/recycled parts are no good can not use because they do not function. Also know of warranty customers charged for fans or forced to buy a heat sink just to get the fan. if you have had same of similar problem I WANT to hear from you. read full review »
