would i be able to overclock my xeon W3690 cpu with out mosfet cooling on this mobo i know i can overclock the cpu but what about mosfet cooling
I would advise against it personally.
Those 130W TDP LGA1366 chips draw a lot of power when you overclock them, which would result in much more heat being generated by the mosfets. Probably more than they could handle really. Unfortunately it doesn't look like mounting heatsinks to the mosfets will be realistically possible with them standing up on their ends like that.
Plus the board only has a 4-pin CPU power connector, probably wouldn't be able to sustain the wattage needed for the CPU for much of an overclock.
Plus this is a board out of a prebuilt PC I'm guessing by the HP logo on the board, they're never really built to handle much more than the parts that were with it from the factory.
I think you'd want to get a better board if you're looking at anything more than just a very minor overclock.
Never try to OC OEM hardware from Dell/HP/Gateway etc. These companies designed their hardware in a completely different light than those of the Retail variety. It is not worth the effort.
the i7 920 is locked hence why xtu wont work
If you do plan on (manage to) overclocking, I would slap a fan on those FETs and add in a couple of 560uF, 4-6 V, Nichion FP-CAP, Sanyo OSCON or Chemicon conductive polymer caps to those empty slots near the Fujitsu(?) VRM caps. I
