I've just built a small HTPC with the following:
- APEX MI-008 Black Steel Mini-ITX Tower Computer Case 250W Power Supply
- AMD A8-3870K Unlocked Llano 3.0GHz Socket FM1 100W Quad-Core Desktop APU (CPU + GPU) with DirectX 11 Graphic AMD Radeon HD 6550D AD3870WNGXBOX
- CORSAIR 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1333 Desktop Memory Model CMV4GX3M2A1333C9
- ASRock A75M-ITX FM1 AMD A75 (Hudson D3) HDMI SATA 6Gb/s USB 3.0 Mini ITX AMD Motherboard
So I realized too late (when assembling) that the CPU heatsink assembly is too large for this case, so I'm running the power supply externally now. What I can't figure out is why when I'm watching the hardware monitor in BIOS (no OS even installed yet), my fan RPM's are at 5k and rising, and my CPU temperature climbed steadily up to 50 deg Celsius ...
This feels wrong. Did I screw up again with the parts above? Should I be checking something? I have the machine off now (been running for only about 10 minutes in it's entire life), and I'm afraid to turn it back on until I have a better idea of what's happening here. Would appreciate any help or advice you could provide!

And yes, as mentioned before, that is my PSU hangin' out the back there...
