What is an average (good) CPU temp when idle? Mine is running at 54 C and I'm not really sure if thats hot or ok....Since i'm testing some overlclocking features on it...
I would think its a little hot but I think mine idles around 45, so I don't think that is so bad.

Mine generally locks up when it gets a bit warmer than that, say around 60C. It idles in the 40s, runs normally in the 50s and gets to overheat point when I run games for a while.
That seems a little bit high for an idle temp. CPU temps will vary from person to person, depending on ambient temp, cpu voltage, how well your case cools, what type of heatsink/fan or h20 cooler you have on it, as well as how clean the intakes, fans and heatsinks are (etc.).
Also, what your using to monitor the cpu temp can make a difference. Some software programs don't read the same as each other or differ from what your motherboard reports.
I think mine rarely gets to 54 degrees even under a load. My 4400+ idles between 36 and 40. Right now, it's sitting idle at 39 degrees. I'd like it to run even cooler though.
I'm using the stock AMD heatsink/fan, which is actually fairly beefy, has heatpipes and alot of copper. My case also has pretty good cooling, with 2 120mm intake fans and an 80mm intake port (all screened), 120mm & 80mm exhaust fans, as well as the two 80mm exhausts on my psu.
Slap on a nice Zalman 7700 or a Thermaltake Big Typhoon cooler, and your temps should drop significantly, especially if your upping the voltage to overclock.
During the Winter mine idles around 35-37c and during the summer 40-45c.
Mine is usually around that, never had any trouble. It's hotter than most people like, but practically it's unlikely to cause any problems or damage. If you're using a stock cooler, consider replacing it with a more powerful model from Thermalright or Zalman (there are others obviously, but I like those 2 :p).
What im using to read the tempurate is a program called "Everest". I wasn't able to find any other one.....
[COLOR=black]My 3500+ (running at 2.45Ghz) runs idle at 30-31°C, and under load at 34°C. I am using a Swiftech H20 Apex Ultra water-cooling kit inside a Thermaltake Armor with two front 120mm fans and one rear 92mm fan (all very low RPM)[/COLOR]
A "safe" or "stable" operating temperature will depend on what CPU you have. Intel CPU's (Northwood/Prescott et al) have a higher thermal output, run generally hotter than AMD CPU's and thus can remain stable at temperatures which AMD CPU's would fail and reboot at. Anything under your motherboard temperature warning threshold I suppose could be considered safe and stable. The threshold, which can be found in the BIOS settings and can be changed or increased if needed. [COLOR="Red"]I would advise against it, you would run the risk of damaging your CPU by removing this safety barrier[/COLOR].
My 3700+ at 2.6GHz runs at 29-30 Degrees Centrigrade Idle. Where do you hail from? I am from Australia, which is generally hot, but at the moment it's quite cool. But either way, 54 Degrees Idle is defenatly on the hot side.
Generaly speaking, you want to keep your CPU below 60°C for longer periods of time.
