Core temps + cpu temps (am i running too hot?)

On the stock heatsink and with arctic silver 5, my temps are (well they change so I'll give the range)

system: 35 c
cpu: 27 c
aux: -13 c
core 0: 49 - 60 c
core 1: 49 - 60 c
core 2: 48 - 60 c
core 3: 50 - 70 c

the temperatures are read by speedfan

am i running to hot? or is this normal? and I'm thinking of buying a zalman 9500, I'm guessing this will help?

and why is core 3 running so hot >.<

I JUST SAW ALL THE CORES RISE AT LEAST 10 C IN TEMP, BRINGING CORE 3 TO 70 C!!! I SHOT DOWN THE COMPUTER IMMEDIATELY.

I HAVE AN ANTEC 900, 5 FANS RUNNING IN THE CASE.

I did not overclock the chip - something isn't right.

umm ok ill try to answer those questios

1) intel q6600 quadcore @2.4

2) g0

3) load testing? im just testing temperatures with speedfan (temperatures I listed are when the computer is idle, btw)

4) my room temp is 75 F

5) stock frequency

6) don't the vcore

7) not sure how to tell if they are running 100% rpm (two fans are med setting, three fans are low setting)

8) case covers are on

speedfan is version 4.34

So what do you make of this... Havent really tested much of my temps since it's been hot. It's about 68F in the house right now.

Running 4.05ghz small FFT's and CPUID hardware monitor, core temp .99 and Speedfan version 4.33 (old but who cares) all read CPU as 58C and core 0 and 1 both are at 64C. Is this good??? I'll let it cool down for a minute before recording idle temps-

Alright: 39-40C idle CPUTIN and on core 0 and 1 temps are 48C. What do you make of all that???

Thanks! I'm running a TRUE both cpu and hsf are lapped with AS5.
