Hi, L3illY, thanks for the tip. Yeah, I brought my system to the stores where I bought the CPU and motherboard from (I said stores because they're not from the same store). Testing the CPU didn't really reveal anything conclusive that the CPU is broken, and testing the board with another CPU (my outgoing Phenom II X3 720) wasn't conclusive that it's defective, either. However, I was unexpectedly able to fix the loud fan noise issue. You see, I used the stock HSF/TIM when I first installed the CPU, and I immediately noticed the loud fan (it's like a small jet taking off!). Before the fix, In the BIOS, the CPU would reach as high as 71C with the HSF spinning at ~6000RPM! The other problem is the wild temp fluctuations under AOD and Coretemp.
Up to this point I've only been using the stock TIM as well as some cheap TIM that I've grown to trust over the years. I then, for some reason, decided to use my 4+ year old tube of Cooler Master TIM, which immediately quieted the HSF! I also did some tweaks to the BIOS to help curb the noise (setting the max temp target for the fan, lower CPU voltages, selecting 'ECO'). Setting the BIOS back to default settings will increase fan speed/noise a bit, but nowhere near as loud as when I first turned the thing on. I guess the stock TIM wasn't good enough, and perhaps a little slow in heat conduction so heat built up inside the CPU quickly. Any thoughts?
Another problem I've been having is the wildly fluctuating temps inside AOD and Coretemp (say, 15C – 23C – 17C – 26C – 30C – 20C... etc. in <1 sec. Internvals). The store where I bought the CPU from said this is the first time he's ever heard of this, and the folks where I bought the mobo from are also at a loss for an explanation. They both suggested, however, that since I bought a very new CPU model and the board's BIOS actually came out before Vishera came out, there may be some kinks to iron out. Also, I have a friend who bought an A10-5800K with a Gigabyte FM2 board, and he seems to be experiencing the same temperature reading problems. His BIOS shows high temps and high RPMs as well, and wild temp fluctuations under Speccy (that's what he uses), so I'm guessing the tools we have today aren't reading these new Piledriver-based chips very well... Not even AMD's own Overdrive app does it right, interestingly. However, he said he tried Gigabyte's hardware monitoring tool and it seemed to read the temps correctly, which is around 40C. I've yet to try MSI's own app, though. It's also interesting that there doesn't seem to be much info about this on the Internet. Perhaps there are just too few Piledriver owners, and those who do don't bother with these temp fluctuations or loud fans and instead go straight to water cooling.
If people stick with you just because you have a Rolex on your wrist, you can bet losing them is as OK as losing an Invicta. And if they stick with you even if you only have an Invicta, losing them is as OK as losing a Rolex.
