Windows 7: Safe CPU Temperatures? running from 9C-24C is it too cold?

I agree with linnemeyerhere. I don't think it is possible to get below ambient temp. So, I really think you are not getting accurate temp readings. But, to ease your mind, I don't think you can get too cool CPU temps, and especially with the stock AMD cooler. Most everyone pays a lot of money for cpu coolers to keep them cooler. If those readings are acurate, i will try to figure out a way to install a stock AMD cooler on my Intel CPU.

The measurement programs do not always correctly report the temp of AMDs. There is a reason because of their sensors, but I forgot the details.

I had an AMD 4800+ reported at 9 degrees celsius - in Florida where the ambient temp was 27 degrees. I would not worry about it.

A possible explanation:
Tcase < Tcore < Tjunction

Tcase is the inside center temperature of the CPU heat sink and I think is generally estimated. The temperature monitoring program has to estimate Tcase using an estimate of the temperature differential between Tcore and Tcase.
When Tcore is low I can see a situation where Tcase can be way out and even present a figure below ambient.
I guess with some wiz bang cooling system you could get Tcase actually below ambient.

Here are the pictures of inside my case, it was the fan i put in the front of the case that made it cool down like it is, before it would be at like 30-40C even with the big fan in the power supply but the fan in the front made that much more of a difference in the cpu temp, and like a 7 degree diff with my motherboard I know looks kinda ghetto but its working for me atm lol

My CPU is running between 11 and 23C ATM. and it is 73F in my house atm.

I agree with that, the new rig I built in my lounge has an AMD A6 3650 and whilst I expect it to run fairly cool I didn't expect the temps that coretemp show for it.

According to coretemp it idles at around 4C lol.

Here is My CPUID Hardware Monitor Specs, I used CPUID Reviewer Kit for AMD FX Bulldozer
which includes the CPUID Hardware Monitor.

There is absolutely no way CPU will be at lower temperature than ambient air with stock cooler, no way unless you do some tricks like by pumping frozen air inside. Sooo the program reads wrong temp, possibly using wrong multiplier on the data it receives from CPU. Your ambient 75F = 24 C and this would be the lowest temp your CPU could possibly be, so you need to add at least 12C to 15C to the readings displayed and even that seems low. I would try using AMD program (they have at least one, me think) to read CPU temp, if anybody knows how to properly decipher CPU temp, it should be them.

download and install Core Temp and see what readings you get. I have always found it to be as accurate as any temp program. If you look at HW Monitor, your +12V shows 8.06V. I know that is not accurate. If it was your computer wouldn't boot.

I already posted the Core Temp Gadget reading on the first page but here is a screen I just took of the Core Temp control.

I see, look how much it kicks itself down to conserve energy 1.4-3.7Ghz

sorry the second screen was over my browser when I took it, you can see the forum behind it kinda in the aero...the core temp on this wall below is saying 1.4Ghz, then the second pic the core temp is 3.7GHZ so it idles really low with the power saving technology. which I think is a contributing factor.
