Hey guys well my evox says my temps are as follows

MB - 107.6 F
CPU - 125.8 F
HDD - 95.0

Now thats with a 120GB 7200 HDD installed and with a 800 mm fan 12 v installed as well. Are those kinda high and could cause over heating problems? and how can i fix this?

Those temps are fine. Towards the low-end, actually - especially on the CPU. I had one box that ran in the upper 120's (cpu) - low 130's, but my new one runs more in the upper 130's - low 140s. Those are a bit on the high side, but still within the "bell curve".

Yours are fine.

If you wanted a little more airflow cut a hole in the hard drive tray so the fan can breathe up more - other than that you are fine.

alright cool and my HD tray has no back i cut it off for max air suckage for 800mm fan
