I bought this food for the first time one of my PC. It works nickel. I recommend one for my second PC, so I get the same model, but this time I heard clicketis when it starts and when I return the tower to stand for stops eating! I almost return the product but I still looked for the cause. It was a big son in the house that stood out too much and that touched blades fans! Unacceptable quality workmanship! I took my screwdriver and I pushed the wire inwards and it appears to have fixed the problem. So on one side it will deserve (for now) 5 stars because it makes the job but on the other hand it would deserve one star because we have a chance to receive a quality exmplaire suspicious. So I'm mean and I met 3 stars.
