help with overclocking i7 3770k heat reach 100 with h80 ?? - Page 2

alright , now i did reset the thermal and replac it with arctic silver 5 and used some cotton and fiber and 70 percent alcohol to clean both cpu and cooler but the heat still aproblem

well i tried to run 4.2 @ first the cpu temps reach between 68 to 75 @ 1.135 vcore

below that vcore the system would BOsd

then i want to go higher so i went to 4.4 with vcore @1.215 (i tried 1.170 /1.175/1.180/1.185/1.190/1.195 etc all gived me bosd but strange thing is the 1.180 to 1.185 last alittle longer untill bosd come )

now i'm trying with 1.215 and see if it will bosd but the heat still a problem (strange thing also that i run yesterday with 1.210 and lasted longer with prime 95 until it BOSD but today when i starded the computer it didn't last even couple of minutes with prime 95 so now i'm trying 1.215 vcore )

peak heat now is 79 /87/83/77 on real temp with full load on prime95 test @ 1.215 vcore and 4.4 ghz


edite :update : now i see warning with temps here is a picture

I get the same with mine on the AVX Prime95. I've also felt very uncomfortable about these ridiculous temps. I tried reseating and all that jazz. I'm running it at 4.5 @ 1.25 and during p95AVX it reaches ~80c (60c in games) which is far too hot imo.

I've also spoke to a lot of others using custom loops etc, and the cooling actually makes very little difference on these chips, once you go past 1.25/1.3ish, the temps just rocket. Most believe it to be the fault of the lack of soldering between the DIE-IHS.

My case has good air flow, and my cooler is far from bad either for an ALC.

Most people also won't recommend de-lidding either, as it's caused some after-issues for some whom have managed to even do this process without damaging the CPU.

I'm at a loss, because there doesn't seem to be any options, other than running it at stock, or round about there..

which cooler are you using ?


well for me the problem is that system BOSD under certen vcore so in that case i need to raise vcore and which mean more heat and i get high heat and i don't know how to deal with it i tried arctic thermal 5 and still i get heat problem now i can't get to 4.6 or 4.8 with these heat because in order to get those speed i need to raise vcore which gave me much trouble with heat with 4.2 @ 1.135 vcore and also with 4.4 @ 1.220 which not stable yet and heat reach 80 so imagine if i gone to 4.6 or 4.8 it's gonna give me a trouble with heat

update :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

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

SO?

Personally run 1.24v at 4.6ghz, fold all day so always at 100% usage, cores average 58-65*C, which i'm lucky for. But I have my four p/p fans on max whole time as well, and exhaust and intake fans too. could be your chip. but whats ur ambients?

58 to 65 wow i wish i could get that cold

well i can't run 4.6 @ 1.24 system would B OSD or don't start at all i can hardly run 4.5 @ 1.280 vcore which i don't know it stable yet (4.5 /1.270 vcore run for 2 hours on prime 95 and then gaved me BOSD)


u could have better chip than mine

any way well room temps around 27 to 30 so weather could be hot some time

well now i changed h80 fans postion as exhasut but temps getting higher

those 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

both with 4.5 @1.280 vcore frown.gif

hey guys! its not the thermal paste, and theres probably nothing from with the cooler either smile.gif
definitely suck in fresh air THROUGH the radiator and have the radiator exhaust warm air INTO the case

yes, your system will be a few degrees warmer, but who cares?
your cpu will be a couple of degrees cooler instead, and which is more important?
having memory/mainboard/hdd a few degrees cooler or the cpu? biggrin.gif

i was shocked when i first played with ivybridge as well, power consumption is really low (~40W at stock speed) but the temperatures are really high compared to sandybridge chips
the reason is the IHS, the metal lid on top of the cpu... its not making good contact with the cpu

some cpus make better contact, some worse...
thats why some get higher temps than others...

on previous cpus intel soldered the metal lid to the silicon CPU chip, which means heat gets transferred really well
On ivybridge intel is using plain white silicon based thermal paste, even worse than the thermal paste most heatsinks come bundled with...

and to make matter worse, ivybridge is made in 22nm, which means the chip itself is much smaller than sandybridge
so all the heat the cpu generates is concentrated on a tiny spot in the center, and the thermal paste between the cpu and the IHS, the metal lid, doesnt transfer it very well

some people have removed the IHS and applied better thermal paste, and ive seen reports of getting over 15C lower temperatures!
this is pretty risky though, as youll have to cut through the silicon glue that holds the IHS in place, to then remove it...
and after youre done, you have to put the IHS back on, and secure it, otherwise your heatsink might crush your CPU chip
silicon is pretty much a glass like crystal, so cracking the edges is easy when installing a cooler in a bad angle

anyhow, ive done this in the past on a bunch of cpus (AMD), but not on ivbybridge yet...
if you really want lower temps, google for IHS REMOVAL guides for ivybridge...

keep in mind though, you lose your warranty if you do this... obviously...
itll let you overclock a few hundred mhz higher probably, or get you 10-20C lower temps... but whether thats worth it for you or not... your call smile.gif

personally, i think ill do it for fun hahah...
but i dont think its worth it... what game needs the extra few hundred mhz anyways eh? smile.gif
