FX8320 Over heating issue

I have an AMD FX8320 running on an ASUS M5A99FX Pro 2. board. With Turbo Core enabled regardless of what I set my cpu voltage to, it always run at 1.38 to 1.42. Which is causing it to overheat. Once I turn of Turbo Core, it stabilizes the vcore and the temps drop considerably. My question is, with Turbo Core enabled, what should I set my multipler to for CPU (if this will impact temps), and what should my voltage be at? Should I set this in my Bios, or using AMD Overdrive (which is what I am currently using to turn off Turbo Core).

Yea on a H60 I wouldn't have Turbo enabled either. My dad has the H60 and a FX 8320 like me. Just stock everything so the CPU speed will throttle back when it is idle unlike mine which is locked in and always at 4.5. This is why the voltage changes. When the CPU kicks it self down so does the voltage. When it kicks up and speeds up, especially if turbo mode is on, it then has to kick up the voltage to keep it stable. I off the top of my head don't know what my vCore is set to since I am not at home but i think it is above 1.4, with my multiplier maxed out, and running what ever FSB it needs to be to run at 4.5. I have the the H100 so i get the Corsair Software and can control pump speed and fan speed etc. When i put it on silent mode it...

The turbo on the 8320 is 4GHZ max so when turbo is turned it it should go up to 4.0 and not 3.5. Either way unless you have Overdrive turned off to prevent CPU throttling it should only run at what ever speed you need it.

I'm more worried about what heatsink do you have on it? Do you have the stock heat stink that came with it? If so that it why. VERY VERY WEAK! you need to get something like the Evo 212 if you case is big enough or a water cooling system or something. I have my 8320 OCed to 4.5 on a Corsair H100i water cooler and no over heatting here what so ever.

^^ Paid attention to these two.

And your voltage should only be as high as it is necessary to run your CPU at a given clock speed. Seeing as you're neither knowledgeable or equipped to overclock (no offense), I would recommend that you do not mess with the BIOS settings until reading up on overclocking guides. You could permanently damage your hardware.

Here is one on the Fx 6300. Same tricks, different CPU. Plenty of guides around on overclocking the Fx.

I should have given a bit more information, I am not intentionally trying to OC my system. It was overheating and I installed AMD overdrive to check the voltages and the temps. I've since stopped using it and installed CPUID Hardware monitor. So with that in mind, please re-read my original question. Why are my vcore voltages jumping all over the place and my cpu temps going crazy. I haven't changed anything in my system, I'm using a Cosair H60 water cooler and I've not had a problem until recently.
Thanks

I have the the H100 so i get the Corsair Software and can control pump speed and fan speed etc. When i put it on silent mode it can get as hot as 65-70 but the PC is wisper quiet. On balanced it stays usually around 50-55 and when i max the fans out even on Prime 95 they never get above 45-47.

My next question is what temps are you getting and when are you getting them? There could be an issue with the H60 as well. My dads pump took a dump, I hear it is common with the H60's and his PC would shut off within a minute of turning on. He then tossed on the Stock fan for the time being while he got it RMAed and at idle the fan was still maxed out (7k RPM) and temps were 65. Just goes to show how bad the stock heat sinks are. Funny though the heatsink that came with my 8320 is better than his. Tossed it on my work machine since its stock fan sucked even more lol.

At idle it is around 55-56, I cant even run any games worth playing as it will shut the PC down. I still have the stock AMD fan and am going to throw that one and see if maybe it is the water pump that is faulty. I appeared to be working fine, I'll test it within the next few hours.

Yea you could be having issues with the water pump. That is where I am putting my money on. Now when you put on the water pump did you use the existing thermal paste on it or did you clean it off and put on new stuff like Artic Silver or something?

I used Artic Silver for the paste and yes it does appear to be the pump. I put on the stock cooler and it now runs at about 43-45 idle, not great, but at least it is not overheating now. I'll have to RMA the pump and go from there. Thank you for the help.
