Intel i7 3770k random temps?

tilyardinit · Sep 22, 2013

Hello my Intel i7 3770k ivy bridge seems to idle quite randomly. The temps when I load up are normally aroun 34-38 idle...I say 34-38 because every second the temps spike up and down with the peak being 40...Under full load I am peaking up to 60 degrees on Arma 3 ultra..Now is it normal for spikes to go up and down between 34-38 within mili seconds or what?

its on original clock this temp ?

tilyardinit · Sep 22, 2013

Yeah it is, although the guy i got it from Overclocked it to 4.2 I decided to keep it at the stock clock.

you have good temps, on your cpu. the maximum CPU temp its about 90ºc and the maximum safe voltages 1,4v memos 1.65v and some cores have more temp because the treads have some work...

my v is like 0.945 atm..so is it normaly for my temps to go from 34-38 then back to 34 in 1 second?

tilyardinit,

Yes, it's normal for Core temperatures to respond almost instantly to a change in load. Remember that 1 second is an eternity to a processor operating at 4.0GHz, which is equal to 1 clock cycle per 0.00000000025 seconds, or 0.25 nanoseconds.

Contrary to Amdlova's statement concerning maximum temperature and voltage, TjMax (Shutdown Temperature) is 105C. Although Intel's processors are capable of operating in the 90's, recommended Core temperatures should be less than 80C. Maximum recommended Vcore (Core Voltage) for 22 Nanometer 3rd & 4th Generation processors is 1.30 Volts. Anything higher accelerates "Electromigration" (premature erosion of traces and junctions within the processor's layers and nano-circuits) and pushes temperatures through the roof, regardless of any practical cooling solutions.

From the Intel Temperature Guide:

3rd Generation i5 3570K / i7 3770K (77 Watts)

Standard Ambient = 22C
Tcase (CPU Temp) = 67C
CPU / Core Offset + 5C
Tjunction (Core Temp) = 72C
Tj Max (Shutdown Temp) = 105C

45 Nanometer 1st Generation Core i ..... 1.40 Vcore
32 Nanometer 2nd Generation Core i .... 1.35 Vcore
22 Nanometer 3rd Generation Core i ..... 1.30 Vcore
22 Nanometer 4th Generation Core i ..... 1.30 Vcore

Amdlova,

Respectfully, if you're not familiar with Intel's specifications and definitions, then please don't offer simple conjectures. Misinformation only causes confusion in the community. The topic of processor temperatures is somewhat complicated, so a detailed explanation is usually required in order to really help anyone.

tilyardinit and Amdlova,

You can gain a better understanding of processor temperatures by reading the following Sticky: Intel Temperature Guide - http://www.tomshardware.com/forum/id-1800828/intel-temperature-guide.html

Hope this helps,
