I recently got rid of my sandy bridge build (2500k with asrock extreme4) and got a 6700k paired with an ASRock Extreme7+. Everything went extremely smoothly with the install but once in windows I noticed a very obnoxious coil whine that was coming from the CPU area. I can't pinpoint the exact component but I can make the noise go away by disabling the C State Support in the bios. For some reason that causes the coil whine to rear it's head when a slight load is put on the processor. That was somewhat remedied. When downloading and using the internet I notice a higher pitched coil whine that seems to be coming from the NIC (Intel I211 and I219-v). On steam when I pause DLing, the sound stops, when I resume DLing it's back. It's very faint but annoying. I asked my fiance to listen for it and she could barely hear it. But a $229.99 board shouldn't do that, right? I contacted Newegg today regarding the coil whine and they issued me a RMA. My sandy bridge build is going to my Dad and I'm waiting on a power supply for him. It won't show up until Wednesday. Do I wait to RMA my board until I try a different PSU? A lot of people online point to the PSU being a culprit of coil whine but the whine is clearly coming from near the CPU. I'm using a Seasonic 750w Gold PSU (purchased in 2011 with my Sandy bridge build). Two questions: 1. Are those common noises for motherboards to have? I don't remember by Extreme 4 sandy build having any weird high pitched noises. 2. I can't for the life of me decide on another board. I really liked the features of the Extreme7 board but I'm very wary on getting another faulty one. The two things I'm looking for are an Intel network adapter, and a good sound solution. I really thought the ALC1150 Purity from ASRock was nice. I've heard awful things about KILLER NICS and Creative Sound 3d or whatever it's called? My plan is to go home from work in a couple hours and tear down the rig and send the motherboard back to Newegg. Thanks for the help. |

Coil whine can happen on occasion but I always make a point of returning products that have it. Typically they last just as long as unaffected products but the noise can be a real bother. If newegg send you back the same board (they don't find an issue) then try another PSU but I suspect it may just be bad luck. If the replacement also has a whine then you may want to replace the PSU anyway. Note down the serial number to be sure if you received the same part or not. -------------

| I'm sending back for a refund and will buy from Amazon next time. In the way of returns they are way easier to deal with than Newegg. So you're saying that if Newegg doesn't feel the noise is loud enough they can say that nothing is wrong with it and send it back to me? If that's the case, that's terrible. |

Sadly many resellers do not consider coil whine to be a defective product. Technically/electrically there is nothing wrong with the product. Newegg is good about allowing RMAs for coil whine however so you shouldn't have any issues. Sorry if I wasn't clear, if you were returning it to newegg for a replacement and they did not find any coil whine then sent you back the same board then it would be time for a new PSU. They would only send back the same board if they did not find an issue with it. Given coil whine is what you are returning it for that would be the first thing they look for. It's a moot point anyway as you are getting a refund. Purchasing a replacement from another retailer is a good idea, it minimalizes the chances of getting a board from the same batch. The odds of getting another board with coil whine are very very slim in this scenario. If you do however experience coil whine on whatever board you purchase from Amazon then I would definitely replace the PSU as in this scenario it would almost certainly be the cause. -------------
