hello,

So i got my evga 790i running with an oem q9450 with a Scythe ninja b heatsink/fan combo, with corsair ddr3 1333mhz ram.

these are my bios settings:

cpu fsb: 1800
memory: 1333

cpu core: 1.3875 (1.336 in cpu-z, lower under load)
cpu fsb: 1.35
memory: 1.675
nforce spp: 1.45
nforce mcp: 1.65

I can hit around 3.7 using this setup, but my problem are my temperatures. Idle temps are about 50-55c, under load, even worse 77c maximum, 75c average. comparing to what ive been reading on some forums, this seems unusually high. When i set to stock speeds, i idle at around 47c and max out at 60c.

75c is too high isnt it? could something be wrong with my ninja b? it doesnt get cold much, but i have tried setting it up different ways which usually results in the same temperatures (i used to run it stock, then i added a scurk1 bracket and i didnt install the copper spacer, then finally im running with the scurk1 with the copper spacer, temps have usually been the same using all these configs)

are my voltages ok? is something too high? or is this simply the overhead from overclocking this chip at this voltage?
is 75c safe (not for 24/7 but for gaming sessions). would it be a good idea to leave my CPU VTT at 1.4, and try to lower my cpu voltage, would this work and improve my cooling (although i always thought 1.4 was too high)?

thanks for any help guys i appreciate it
