overclock too hot?

[MrSufyaan]

I overclocked my i5 3570k for the first time today to 4.2Ghz. Had Prime95 on for an hour and the max temp i got was 80c with it floating around 70-80 under load. I'm using a H40i water cooler but I feel the temp is way too high. Any ideas on lowering it?

remember prime95 are unreal temps; what your hitting is the extreme temp which you will never see in a real world situation, so if the OC is stable try it in a very CPU intensive game like BF4 and see what you get, you will be very surprised

Whats the voltage? The temps aren't too bad for prime95.

I played like 10 mins of Wolfenstien and the max it hit was 54c

It's a preset OC on the Asrock extreme4 mobo. The voltage is auto I think.

80*C is well within the maximum operating temperature limit. Keep in mind, you are using a lower-tier H40, so it isn't too bad.

You shouldn't be using Prime95 as a stress test on Ivy-Bridge and new generation of Intel CPUs. It causes weird interference with the voltage and/or other settings.

You are better off the use the Stability Testing program built into AIDA64, or Intel's very own "Intel Burn Test."

 

Best to manually input the voltages and overclock into the BIOS.

Auto will typically use more voltage than necessary, as a result, higher temperatures.

Since it is on Auto, Prime95 will cause the system to pull more voltage.

Thanks for the info. what would you suggest is a good voltage to aim for? (very much a noob at OCing)

You are fine, temps under prime or any stress test application are unreal temps for gaming and video editing, for rule of thumb Intel CPU's are good up intel 85C and amd is good up till about 65 as the 8 core 8350 is based off of a server chip its got lower thermal limits

It really all depends on the characteristic of your CPU, but typically, you don't want to go beyond 1.3V on the Core Voltage. As for the other voltage settings, I'm not 100% sure; I haven't owned an Intel CPU since socket LGA 1156 (i5-750).
