Specs: Windows Vista, 4 gig OCZ
i cpu is running 155 degrees while in games and 112 while idle is the 155 to hot i am running an AMD phenom 9950 quad core black box with an after market heat sink and fan and with arctic silver compond in a cool master case with a 110mm intake fan an 80mm exhast fan a 40mm cpu fan and a 650w corsair ps

I assume those numbers are in F? Temps are generally reported in C, so your temps would be approx 44C at idle, 68C under load. I'd say they're a bit on the high side but not dangerously so. Make sure you've installed the heatsink correctly. You only need a tiny dab of Arctic Silver in the center of the CPU. If you used too much or spread it around like frosting a cake, it can affect the heat transfer. Here's the instructions:

40MM is awfully small for a CPU cooling fan, are you sure about that size? Which aftermarket HSF did you buy? As for the case cooling setup. all you really need is a rear exhaust fan. Front intake fans are of little benefit & side panel fans should not be used. Check these AMD Builder's guides:

If those temps are in F, then your at 46C idle and 68C under load (Celsius is what most of us normally use for CPU's.
You have not included much in specs which will make it difficult to be evaluate this.
If you are running this CPU at stock settings, then you are running pretty hot at idle and probably nearing the thermal shut down point for your CPU under load (What load? Stress test? Game???) and should definitely get them down. I would suggest read Actic Silver's online instructions for you CPU on how to apply it and try again (too much compound, or air bubbles due to spreading can be as bad or worse than a touch too little) and try resetting BIOS to defaults.
If you are overclocking, you might be pushing the voltage a little to high, you want only enough to reach stability.
Post back ALL of your specs including make and model of all of your hardware and your current BIOS settings for a real evaluation of what you have there. My experience is more with Intel, so others will give you more detailed answers when you supply the information that they need.

You have to be a little bit crazy to keep you from going insane.

Well if you are asking this only in regards to the chip itself, I believe that AMD considers 65 C the max temp for their current CPU line-up. Not sure if this is true with the AMD 9950, but I know that I would be worried at anything above 60 C, especially with a quad core. For AMD chips the sweet spot is to not break 55 C. When was the last time that you cleaned the CPU and heatsink and reapplied your thermal paste?

I'm using a Phenom II x4 965 and I don't even hit 55 C running at 4Ghz so that just seems high to me, especially if you are using an aftermarket cooling solution.

Antec Three Hundred Mid Tower

AMD Phenom II X4 965 3.4GHz @ 4GHz stock heatsink

2x2GB G.Skill DDR3 1333MHz @ 7-7-7-21 2T, 1.5v

Nvidia GTX 460 1GB 830mhz core/1660 shader/2100mhz memory
