So I just installed the Corsair H80i last night and am Ding some small OC in BIOS.
This is my first time OC'ing and have been reading up here and some You Tube Tutorials.
According to Speed Fan and CPUID my IDLE temps are 25-27c and Corsair link has the CPU at Idle 14-18c.
At 4400mhz at 1.4v Prime blend test has my AMD 8350 between 58-62c ( I know that near/at max for this CPU) where corsair is showing 10 15 degrees lower than that.
So which monitor is more accurate I need to know else if I go with CPUID and speed fan I'm max overclocked now at 4.4.
BTW 2nd question if the 8350 max temp is 62c...then does that mean it safe and stable to run 58-62c?
Thanks for all the help

The temps are very important when overclocking as you know and keeping an eye on the temps becomes the most important part of the overclock as you get to the higher clock speeds. I don't have an AMD cpu so I can't say what the temps should be but a top temp of 62c seems very low to me and maybe some more research is in order. My Intel cpu has a top temp limit of 90c , so there is quite a difference there. I would get another program to check your temps to make sure and Real Temp is what I use and is very accurate. If you get two or three programs saying the same temp then that's what it is. If it turns out that the max temp for that cppu is 62c then I would not run the cpu at that it's too close to the limit and any added temp will shut the Pc down, like in the middle of a game or intense work application.
I'm going to post this and then do some research on that cpu's temp limit and report back what I find.

Well from what I've been able to find the 62c seems to be the limit and you'll have to work around that number. You'll want to get a temp program that will be accurate so you don't end up with damaging your cpu and you'll have to get a target clock speed that your happy with. It's not always necessary to go with the highest clock speed that you can get but rather a clock speed that's good for the cpu, will give you increased performance and not be causing instability issues. Every cpu will overclock just a bit different and just because you see someone get 4.9ghz doesn't mean that you can take the settings he used and get 4.9ghz on your cpu, you have to do the overclock and see what you end up with.
I have an Intel i7-3930k and I thought I was going to get somewhere between 4.8ghz and 5.0ghz and when I did the overclock I got it stable at 4.7ghz and then thought about it and lowered it to 4.5ghz figuring that this would give me a really good performance increase over stock speed and not be running the cpu at or near the top limit. That was my choice and you'll have to do the same thing, decide what you want to run the cpu at based on what the overclock did.

Well the only thing I do intensive with this rig is game, no video editing or other stuff, ........Depends on what you mean by stable, I guess, I have my OC now set (in bios) at 4.7ghz at 1.47volts.
I primed for 15 minutes twice with no errors or core shut offs (test stops). My temps however (according to speedfan) got at high as 75c.
Now at this OC I've gamed for about 4 hours strait with BF3, Hawken and Planetside2 all at max settings and not once did my speedfan temp get above 49c.
I realize for the OC enthusiasts That Prime95'ing for hours is the "Gold Standard" for a stable clock but if the heaviest, and most graphically intensive game available, at the highest settings, never push my CPU more than 60 percent of what a prime 95 blend test does......then I should be ok right?
BTW I settle at 4.7g at 1.47v because I could not get prime to run 4.8g at any volt up to 1.5 without a core failing within 5 minutes.

Ok , stable is exactly what you have done, run Prime for a time, game for several hours and during this whole time your computer did not crash or blue screen, the games ran smooth at your regular settings that you want to play at and you saw no artifacts or odd things going on with the display. That's stable!
The one thing to remember is this, when you run Prime for a number of hours your stressing your cpu ,ram and video card at 100% get 75c and that's the highest temp that you will see, there is nothing else that you will do on the computer that will push the cpu temp as high so you are good!

The one thing is that when stress testing usually you would run Prime for 6 to 8 hours for a burn in and to prove stability.
So now you have a choice to run at 4.7 or 4.6 because the lower number would be better for the life of the cpu but you can run at 4.7 if you want, your choice. When I say the life of the cpu I'm rreferring to the fact the when you add voltage to a cpu it can tend to shorten the life of the cpu over time. Mostly it's not something to worry about if you plan to upgrade every 4 or 5 years but if you were wanting to keep this cpu for longer then you might eventually find out that it will not last as long as one that isn't overclocked.
