High temps when overclocking i7 3770k with corsair h80

well i just build my pc and wanted to overclock it and started with offsets voltage but when i overclock it under strees tests the voltage become (above 1.350 some time reach 1.4) settings and speed of 44 *100=4.4 ghz (BTW : i tried asus auto tuning but the system restarts and i end up clear cmos so i can boot the system again)


well the problem now it take too much voltage and warning appears and grab alot of heat

so i gone for manual vcore and i starded with 4.2 with v core of 1.135 and it has been somewhat stable but the temps are high

http://i47.tinypic.com/1pa23q.jpg (these picture shoot when first started prime 95)

after while with same sittings now i get these heat (http://i50.tinypic.com/33jqq0g.jpg)


with overclocking to 4.4 with v core 1.220 it gaved me Bosd and temps reach something like these 77/83/80/79 with realtemps under full load with prime 95 some time go above 85

by the way i tried to apply new thermal and cleaned the pervious thermal with alchoal 70 % / coton /fiber clothing and apply arctic silver 5 but temps still a problem

system rig :


i7 3770k
cpu cooler corsair h80
4*4g Gskill trident X 2400 @ defulte speed 1600

motherboard p8z77-v

gtx 670 sli

sesonic 750 watt
cooler master haf x full tower

Those temperatures are expected.

Remember, Ivybridge runs up to 20C hotter than sandybridge when overclocked.

This article came out in May here at Thomshardware and it will help shed some light on what your experiencing.
It's not the thermal compound or the way it's applied (if done correctly that is) but the actual design of the cpu itself. The Ivy Bridge was not designed to be a serious overclocker , it was designed to be a serious low power consumer and it's this low power trait that is causing overclocking issues with heat. Sandy Bridge is the serious overclocking cpu.

thanks for replaying well , i read the artical and i noticed some people having issue with heat also but i saw some videos of asus them doing these overclock to 4.8 with z77 mobo and i7 3770 k i didn't notice their temps but there was no warning to temps with asus ii suit

well now i'm runing @ 4.5 v core 1.270 (i tried 1.260/ 1.265 but it gaved me BOSD )
@ full load temps are as shown in picture along with asus suite ii warning

http://i50.tinypic.com/w78rc.jpg

after while the heat become like these http://i45.tinypic.com/awqe0x.jpg

i didn't get asus warning now but some time it come and go depending on the heat

so what heat i shouldn't reach with full load ?

Edite : well now system gaved me bosd so that's requir more vcore to 1.275 which gonna bumpo the heat to these along with warning cpu 71.0 centigrade

On the screen shot in the real temp window where it says minimum temps , those are the temps that would be the maximum that you want to see.
First thing you want to do is turn off the Asus ii suite it will cause you nothing but problems with your overclock.
With an overclock you do not want to see temps in the high 80's and low 90's with a full load.

i closed asus suit but i can't get below 80's all my temps ar higher than 80's and 90's or het 100 =/
on prime full load with 1.275 vcor and 4.5 and i don't even feel it's stable yet because prime 95 stopped working by it self which in these case go more vcore would make temps go crazy (room temp are 30 degrees )

these picture jus took it now on prime full load with 1.275 vcor and 4.5

same settings but without full load

so how to fix these heat issue !!!

When doing this stress testing in Prime 95 and getting the high temps are you feeling the heat coming from the radiator? With those temps there should be a lot of heat coming from the radiator and is the fan on the radiator running at full speed?
When you installed the H-80 was the thermal compound preapplied to the cpu block?

Are the fans push+pull?

If you applied new thermal compound then you should have applied it in a very thin layer , as thin as you possably can. If it is applied in too thick of a layer then the thermal compound will act as an insulator instead of a thermal conductor of heat.

no i don't feel the heat acautly i feel cool air coming out of h80 when i put my hand to feel it , and yes fans are @ full speed max , yes there was pre thermal already on the h80 but i removed it and applied arctic silver 5 because i was see alot of heat so i changed thermal to see if it gonna make a differance

well i don't know how much thermal did i put but it's like medium not too much and not a little and i acuetly did remove the cooler after putting thermal to see if it spread or not , could it be make air bubble inside the thermal when i removed it to check it ?

should i try to put new thermal again ?

well yesterday i thought to change fans position (i was making them as exhaust because the fan that i removed from haf x full tower was exhaust one so i changed them to let the air go inside as corsair did it in their installing video and i can feel diffrance in temps alittle bit )
i noticed that when i changed fan position that speed can run on low vcore i don't hav explanation but if i were runing 4.5 @ 1.260 on the fan as exhaust these won't be stable but when i changed the fan position tolet the air go inside i can boot with these vcore and these speed

however temps are not great still alittle high

those are temps for 4.5 @ vcore 1.260

http://i45.tinypic.com/29fqa0z.jpg

by the way i noticed temps change depending on room temps also

yes there is digital button and i made it @ max speed but still these temps are way high for the overclocking i'm doing

No, like are the fans oriented so it's a push pull setup?

Like this:


Both fans are blowing the same direction.

if u are asking if both fans in same direction well yes they are but the air go inside the case instead of out side the case

when i removed the 120fan that it was using as exhuast on the haf x full tower i did the same for corsair h80fans and used them as exhaust also

but yesterday i was thinking that if i changed their direction maybe it help to drop temps so i changed there position and made the fans below the air inside the case and i noticed temps drops alittle bit but still not good temprature thats i should be belwo 80's

You want it to go out, not in.

i was making it go out but it makes temps go high !! well if i back to make the h80 as exhaust temps would be higher

so ....... !!!

When your getting high temps then you should feel heat coming from the radiator it you don't then the radiator is not doing it's job and something is wrong. I have water coolig and have been using it for years , when the video cards or the cpu is under a heavy load and the temps are rising if I put my hand over the fans that are blowing ait from the radiator I can feel the hot air.
If you put your hand over the fan and the cpu is idle and you should feeel cool ais and then if you put the cpu under 100% load and put your hand over the fan blowing air from the radiator and feel the same cool air then the cpu cooler is not working and one cause may be too much thermal compound and the other cause may be that the pump is not moving the liquid threough the radiator.

well i could feel cool heat mexd with alittle heat

these temps when i was usning h80fans as blowing the air inside the case

http://i50.tinypic.com/ibg96c.jpg

and these using h80 fan as blowing air out side the case as exhaust
http://i50.tinypic.com/2rxww11.jpg

both with 4.5 @1.280 vcore
