Should I adjust my Overclock?

Hello, so I just recently overclocked my i5 2500k to 4.5ghz. I left all the voltages on auto and booted into windows. I then started to run prime95 to stress my cpu. I let it run for 5 /12 hours and no problems detected But I'm a little concerned/unsure. The only problem I noticed was during the prime95 test all my cores were very hot. Running between 67-79(one core it 80) degrees Celsius. I'm using the CoolerMaster Hyper 212 as my heatsink. So I did a test. I went to play BF3 and my overclock kicked in right away, the turbo boost went to 4.5ghz The game wasn't using 100%, rather just under 60% of my cpu. The temps were fine while playing BF3. They never went over 60 degrees. So my question is. Should I adjust my clock and maybe try a lower vcore because prime95 showed hot temps under full stress? Or can I leave it at what it is because in a real scenario(Playing games like BF3) my temps were great. any thoughts?

Prime95 runs the CPU very hot because it is very intensive. Temp seem great! Although, what is your max Vcore?

Yeah, I run mine at those voltages too, just I use offset. You may be able to get it lower and if you do, it may lower temps a little.

It allows your machine to hit a certain voltage, but then it drops down. So, my offset allows me to hit somewhere around 1.36v i believe, but still goes down to around 1v when in power saving mode.

Yes, auto voltage will also do that, just it generally overvolts it under load. It is Intel SpeedStep. It clocks the CPU down in clock and lowers its voltage to reduce heat, noise, and power consumption. You are fine.

A simple factory sealed water cpu cooler will take 5-10'C off your temps easily. Generally, the cooler the CPU the better. Here are some ideas:

easy install. You mount the smaller ones to the rear exhaust where the normal 120-140mm fan is. But if you are happy with your 212, then I am happy for you too

You can mount on top also; basically almost anywhere that a 120mm fan goes for the smaller ones. But you reallyu want to pull cold air into the case if you can.

If you're happy, then I am happy too

But... you are probably stuck with those temps for that OC on an air cooler. I run 4.5 @1.35v and have 100% load temps around 60'C with my H100 on low fan speed. you could easily drop 5-10'C seriously probably more and then your cpu would then be happy too

I used both, but manually setting the vcore solidified my OC and I know what the max voltage is.

Go into the voltage settings and there should be something that says auto, manual/fixed, and offset voltage. Then you set it and that is it. Make sure voltages are not too high though. Pretty simple.
