I'm sorry that it took so long to get back to this. I've done further tests now, and while I'm not sure what HT bus is, I found something that said HT Link Speed in one of the benchmarks, which said 1000MHz. In BIOS, my system started with mobo-temperature 24 (which gradually rose to 28, not a big deal) celsius, and CPU 36, which gradually rose to 44. There's a FSB multiplier of 16x, which is also maximum. The CPU overview in BIOS is greyed out, by the way.
Anyways. I read out similar temperatures in Windows with the tools you suggested, HDD at 19c, mobo at 36c and CPU at 34. I'll attach the outputs from the different tools here. I suppose the screenshots are the most interesting parts. I have nothing to compare any of the results with, so please help me out.
[Edit] I couldn't even load PCMark05. For some reason it hangs at the loading screen. When it comes to Sandra, it's currently working on the "Cache and Memory" test, but it's been working for 15 minutes straight. What can this mean? Does this help pinpoint my problem?
