What is the opinion of Reddit about the
Generic Desktop Computer Mainboard Case Internal Speaker Connector Plug?

Actually you need a motherboard speaker plugged(http://www.amazon.com/Generic-Computer-Mainboard-Internal-Connector/dp/B010HSSY8Y/ref=sr_1_1?ie=UTF8&qid=1452710420&sr=8-1&keywords=motherboard+speaker) in for your motherboard to beep. They are quite cheap either from your local computer parts shop or from amazon. Consider investing in one if you do not own one. If you can get a beep or multiple beeps then it may be more likely you got unlucky and received a DOA CPU. I actually had one very recently while building my new PC. RMA’d it and 2nd CPU has been running with no problem from the get go.
