E8400 TEMP ISSUE,VERY DETAILED,looking for answers!!!!
RECENTLY I FOUND LOTS PPL HAVE SAME TEMP ISSUE WITH NEW E8400
I HAVE A E8400 BATCH#Q746AXXX BRAND NEW BUILT SYSTEM,i first bought a E6850 cpu and core temp both run around 35C,later on i picked up a E8400 and installed,but i realized cpu temp is 3-5c cooler but core temp is 10c higher than the E6850,so i start researching the forums,very confusing i found lots ppl have same high temp as mine,but some ppl have a much lower core temp,some are as low as 20C ish and 30C and 40C ish.
i have done these:
1.reinstall my cpu cooler 8-10 times(some ppl say might be a contact issue)
2.apply thermal grease with a drop or flat surface,swapped from zalman to artic silver 5(tried a single drop in center or full flat surface)
3.swapped cpu cooler with another diff one.
but i still get same temp result.
UNUSUAL THINGS:
1.even coretemp or HWmonitor reads core temp at 60c,my heatsink still feels very cool,when i touched my old amd64 heatsink,it feels warm.so i think may be my cooler is not contact with my cpu,but whenever i pull it out,it feels very sticky with cpu,i had to force a little bit to take the cooler out.then i tried No.2
2.i disconnected fan and leave heatsink on,my cpu temp went up slowly 5-8C higher and core temp went up 5C only.(i thought my cooler is bad or useless then i completely removed it,boot up,touched cpu,it is so hot and system shuts off,i also went to bought another cooler,same temp result,so it's not cpu cooler,but both cooler i tried r zalman 9700,one is copper one is nt)
3.core temp only went up around 5C when overclock from stock speed to 4.05ghz,my older cpu gets much hotter even with a 200mhz increasement.i think something is WRONG
4.when i do stress cpu test,both core and cpu temp reading increase rapidly less than a sec,for example,core temp idle shows at 49c,right after i click ORTHOS go,core temp jumps to 59c instant,then goes 1c higher per sec,peak at 63C,after i click stop,core temp reading jump down to 52C instant then goes 1C lower per sec and stop at 49C,isnt temp increasement should be at a slow rate with 1C in between???
I AM USING A ZALMAN 9700 NT which should be a good cooler,and i read some ppl from china have the same temp issue,some as high as mine,some even higher,and some are very low.so whats the deal???
current reading is cpu temp 33c,core temp 49c [email protected]@1.32v
i am using EVGA 780I flashed to latest bios.
but everything runs fine,so any experts can figure out what's going on????
