5820k OC temp Spikes

[Manotas]

Hi everybody.

So, I overclocked my 5820k to 4.5Ghz @1.3v. I use a CM Hyper 212 EVO cooler, I know is a low end cooler for my setup, but I just want to test the silicon. So, obviously, the temps hit very high marks (91ºC on AIDA 64 and Real bench both on over an hour test). The stability of the system is perfect, i haven't had any problems, working, gamming or editing. but what caught my attention, is that the core temps spike from said 70ºC to 89ºc then go back to 69ºC in a single second, in fact, the statics of the AIDA 64 says that the average temps of the cores were something on the 78ºC range.

The question I want to ask is whether that temps spikes are a normal thing or is something failing on my system?.

Manotas,

Welcome to Tom's!

I agree that a CM Hyper 212 EVO can't possibly cool your 6 Core / 12 Thread 140 Watt 5820K, especially at 1.3 volts, where it's likely dissipating closer to 180 Watts.

Concernng Core temperature spikes, AIDA64 and RealBench are fluctuating workloads which have fluctuating Core temperatures. Instead use Prime95 V26.6 Small FFT's which is a steady workload that has steady Core temperatures.

Prime95 version 26.6 - http://windows-downloads-center.blogspot.com/2011/04/prime95-266.html

Make sure that you do NOT use a later version. Run only Small FFT’s.
