    Default why temperature seem high for low voltage overclock

    hello just got my g3258 in my asrock z97 anniversary board. I was able to get it to run stable at 4.1 ghz at 1.1 volts . the idle temp was good at 30c but in stress test the temperature went to 70c. If i use 1.2v to get higher speed the temp will be 85c.

    Is there something wrong with this cpu? shouldnt be that hot right?

    Hello Varman, that temp does seem a little high at that voltage, I'm running a G3258 on my MSI H81m E33 board with the stock cooler from my 4790K and I've got it at 4.2GHz @1.136v and when I run OCCT for 15mins my temps are 65 max, depending on your cooling setup I think you could get lower temps, although 70c for 4.1GHz won't hurt the cpu, if I were you I would reseat your cooler clean the cpu and reapply the thermal compound.
    If you don't mind list you system in a bit more detail

    i am using nzxt case s340 it has 2 front fans a top and rear fan. My graphics cards is hd7850 was idling at 27c the whole time. I reseated the cpu with some very very old mx-2 artic silver like 10 years old. The results were the same , idles around 30c and max test temp was 69c still running 4.1ghz at 1.1v...i did lower the cpu input voltaget from 1.9 to 1.75 but that made no differences i think. tomorrow i will try to redo the paste i think i might have shifted the heat sink as i was lowering it down into the motherboard.

    also what idle temperature do you have on your g3258?

    Ive used 10 year old Artic silver 5 and it still work ok, The cpu input voltage I lowered a tad but like you say has little effect on lowering temps

    Sounds like you got good fan setup, I prefer to use the spread method when it comes to thermal paste a thin layer, but we all use our own methods which if done right give very little difference, I got an Aerocool DS200 case it has a 200mm front fan and a 120mm rear fan, graphics card is Gigabyte GTX 660, Hope you get temps to lower a bit...

    hello there is that overclocked temperature? either case that temp is very nice. This morning i redo the paste and ran intel benchmark the highest temp i got was 66C havnt try prime 95 yet. so i guess it is a little better. Also the lowest idle temp i got was 27c and 25c

    Hi, Yes thats 4.2GHz @1.1360v the Stock 4790K fan seems not a bad fan, I had that spare because on my 4790k I got the Noctua NH-D15, well it sounds like you got it sorted hey
    I use Realbench, OCCT, Aida64 stress tests and Of coarse Prime95, XTU. anyway realword temps are going to be a lot lower than stress tests temps,
    Glad you got it sorted, maybe you can crank the speed up if you want without worring about temps so much, nice work!
