I was thinking, onemilimeter, you should video your noisy motherboard also because yours makes more of a high pitched noise if memory serves me well. Video it and then upload it to youtube or similar and then pm runn3r with the address. It may give them more to go on.
Mine (P1 & P2) have some similarities to that shown in this YouTube video, though they're not exactly the same. I do not have a video recorder. I only have a cheap "headset" and I'm not sure if it's good enough to pick-up especially the high-pitch noise (P2). I will try to find how I can record a sound...
That noise is terrible 
I must admit that noise is worse than the low throbbing sound that comes from mine. It is not so annoying as that but because it is such a low frequency it travels as vibrations through the desk as well. I only used my digital camera with it set to video capture and my stethoscope.
If we are not happy or they can't fix it, can we get a refund?
Also where did u get the scope from? Are u a doc?
I also hear this really loud annoying cricket like sound, what's that?
Joker, I would say that theoretically, you would , in law, be entitled to a refund because the Trade Description Act states that any item that you purchase "must be fit for the purpose that it is sold". As such even though the board actually functions it isn't supposed to make an ungodly din next to you
I am unemployed now, since my stroke, but every cloud has a silver lining and it enables me to spend more time on my computer.
Anyone can buy a stethoscope though, just google it and there are a multitude of firms that would be more than happy to sell you one.
That really loud annoying cricket like sound is just that( really loud and annoying) just crickets for my lizards to eat. I have a large vivarium built into my office and even though iot is double glazed, mainly to keep the heat in, the crickets in there amke a god awful noise especially at night. You do tend to get used to it thogh, it's a bit like living in the jungle!
