Overclocking What Tcase are you comfortable with on Ivy Bridge?

I know the specs say 67.4°C, but that's a lot lower than the Tj Max, which is 105°C.
Are you getting that big deltas between Tcase and Tj (core temperatures)?
What do you think can happen past Tcase Max?

 

Hmm... either no one has an overclocked Ivy Bridge, or no one pays attention to the Tcase values.
Should I ignore it and only watch the core temperatures?

 

I don't think many people do :thumbup:

So Intel just listed that value to scare overclockers?

I wonder what differences in temperature you get between the case and the cores. I get between 3-9ºC, usually about 5ºC. Is that normal or do I have a bad sensor?

 

General rule of overclocking sub 80c and your ok

 

Is this the same for AMD?

 

I've heard this doesn't apply to Ivy Bridge, as they get a bit hotter than earlier CPUs.

We need some definite information, not just rumors or such, so if you know something, please step forward and enlighten us!

 

Its mostly all about Vcore and temps, the general advice id give to any newbie in overclocking, Stay below 1.3vcore and 80c in temps on intel platforms, This applys to Ivy Bridge or Sandybridge also for long term chip health. ( I personally own the x79 platform with 3960k chip and a I7950 x58 platform the later is games platform the former is video photo edit work.)

Every chip will require different Vcore to hit a certain Overclock, thats why people sell high end chips on this forum then buy another with a different serial in the hope it will overclock better.

Bit Tech used to have several guides on this forum for the older chips they still apply to this day, Start in small increments and increase as you go along.

If your heavily into high end watercooling then the 80c does not apply as you will never see it, even on water i would personally stay below 1.4vcore. I personally brought intels overclocking warranty so i could push a few chips to the limits to see what would happen, They still work fine.

I have never overclocked an AMD platform since the old FX series about 10 years ago, Only person on this forum who has AMD overclocked to any high end level is Tundra as far as im aware.

As for Tjcase Vs tjCore most temp programs take the core temps only.

 

OK, so Tcase is not that important to stay within spec, it's the core temps that have to be kept within reasonable values.

HWMonitor does show the Tcase.


This is a 3570K after only a few mins of Prime95 at sock! The cooler is Arctic Cooling Freezer 13 Pro
The core temps aren't so bad, but the temperature of the case is closing in on Tcase Max (67.4°C) which worries me.


I'd be interested to see what your Sandy/-E/Ivy Bridge CPUs report for Tcase as opposed to core temps when overclocked.

 

Your temps are fine for the record ill get some screens up once I'm back from work

Bit tech ran there review chip in the 90c + mark, for reference.

 

Yes, but would you do that for longer periods? What would be a maximum temperature for 24/7 100% operation?

 

Below is a quick side by side comparison that i had around from overclocking. Niether chip is currently overclocked. Has not been since mid march.



http://www.bit-tech.net/hardware/cpus/2012/05/01/intel-core-i5-3570k-cpu-review/8 orginal review with tj max temps on

 

As to your other question depends how long you want to keep the chip.

3-4 years 80+
4-7 years 60-70 + np

Stock cooler remember keeps the chip at around 80c anyway

 

Well, this seems as good a place as any to brag:
3570K @ 4.3GHz (more coming soon) max temps around 37C on water
Plenty more head room for me I think.

 

Thanks rollo. Have some +rep.

 

Source please? Sounds like yet another rumor to me.

 

Always thought voltage makes a far bigger difference to life span than temperature since higher voltage increases electron migration. According to here Intel's recommendation is 67.4 C for max Tcase although most say as long as tcore is below 80 your fine. From their datasheet (p103) 1.35 V is max recommended voltage.

 

I believe so too, but unfortunately it's an unsourced claim again.

It only says "Tcase", there's nothing about "maximum". And "most say" sounds like a rumor again.

 

The stock ivy bridge cooler will not keep a 3570k at stock speed under full load under that 67.4c.

in bit techs own review of coolers they have the stock cooler 73c above ambient under full load at stock speed that means its aproaching the mid 90s under load.

If intel were really worried about a tjmax of 67.4c which is alot lower than the 105c other websites have claimed ( Bit Tech, Anandtech) they would of supplied a better cooler or not a cooler at all as they did with the x79 series of chips.
