I need to replace a fan for a user for her CPU. The fan is making a horrible noise...I tried Silicone spray, that helped only for about 4 days and it started again. I have pictures of the fan below with the model information. It's kind of sketchy and hard to make out. Can someone send me a link where I can get this replacement fan without having to buy one off ebay? Our company isn't going to do that. I can't seem to find it on Google.
