Hi, I recently ordered and got my cyberpower pc. However the intel i7 4770k cpu 20% overclocked is very hot. It never goes below 68c. I dont know if this is normal or not. When i tried to max out minecraft with my gtx 770 idk why my cpu got very hot and sounded like it was steaming. I have a watercooling system btw. When i tried to see how good my computer was on this test thing bulit in on the windows 8 control panel, it went over 95c on a simple test! On Cpu-Z it says the core voltage is 1.502 v. Core speed 4190.35 MHz and multiplier is x 42.0 ( 8-42 ). If anyone can help me it would be appreciated, thank you for your time.

1.502 vcore holy crap no wonder its so hot. You will need to bring that voltage WAY down.

That's why I never buy a prebuilt from cyberpower. Anyway, go to bios by restarting the computer and keep tapping F2 button and change the CPU Vcore from 1.502 to 1.150.

Is that all I do? It will still be overclocked right? Sorry I probably sound like the biggest pc noob on the planet

Its hard to say if it will be stable at that voltage with the OC but yes it will stay overclocked as long as you don't change the multiplier. Anything over ~1.25v (maybe 1.3) or so is too high in general.

Try 1.150 first. If it's not stable, change it to 1.200v

22 Nanometer processors (3rd & 4th Generation Core i) should not be set to exceed 1.30 Vcore.

I have it set to 1.150 vcore and it stays at around 50c when im doing nothing, is this a good temp or is it still too high?

Still a bit high. How does it do under load?

do you know which water cooler it's using?

imo, if cyberpower sold that PC to you overclocked already, id contact them immediately and tell them that the CPU uses 1.502v for the slightest overclock of 4.2ghz...

any water cooling kit should be able to give you around 30C-40C when the CPU is idling... 50C+ and a small overclock of 4.2ghz is unacceptable when the CPU is doing nothing; not to mention the extreme amount of voltage being pushed through the CPU (that kind of voltage is generally used when using liquid nitrogen/custom water loops to cool the CPU)... id be one angry customer :( .

however, there is always a possibility of defective components but, whether you have a bad part or not if Cyberpower was the one that pre-overclocked your CPU for you, they'll have some explaining to do

Hey thanks man, I just sent them an email right now. Hope their customer service is better than their sales department! :lol:

heh, a buddy of mine told me it's no better or worse than it's competitors so i wouldn't be too scared :D

Either you got a bad chip or a bad cooler.

My 4770K idles @ 30-35C running at constant 4.4Ghz @ 1.115v and on stress test only stays at 75C MAX

Well will they give me a refund or something? or is there anything else I can do?
