hi guys i have found out why my cpu would not go over 3.5 .
It was the cpu tremanation was low
but the next problem is i dont know what a (safe temp) will be using intel burn test for 45nm prossesors
prime 95 seems to give me about the same temps under load

if i use 1.35volts@ 3.8ghz wanted 4.0ghz the temp shoots up to 90c in a blink of an eye at 3.7 the temps are hitting 85c and i dont know what to do
ps i know i can get it stable but the temps worry me

please guys what would you do in my case

specks again

ep45-ud3r
q9450@3.5 with true @1.175volts (bios)120 (silenx 120mm 90cfm fan push pull)

ocz reaper 1066@1055
asus gtx 280 (no oc) gets to hot as it is
enermax galexy 1000watt psu

thanks again if anyone can help
