TIM is Behind Ivy Bridge Temperatures After All

?

Should Intel release a new IVB revision to address temperatures?

    Here is an Intel Pentium 4 Celeron 1,7GHz (Willamette, SL69Z), which also used Thermal paste:

    I can't believe Intel spent a decade and poured all those billions into developing their impressive 3D transistors, only to squander that advantage over some crappy TIM! :nutkick:

    I promise you it wasn't the engineers that wanted it, but the marketers and beancounters within the company. The arguments must have been something else. Shame none of that leaked out.

    I'm so glad I didn't jump into IB and got my lovely 2700K. :D

    Right, you heard this prediction here first: Intel will backpedal on this decision now that this is out and make a new version of IB with either better TIM or a proper solder connection. They will then offer an optional recall of these processors soon after for the fixed versions.

    Tell us how you removed it please.

    Those are not great temps. Your CPU should not reach 65c unless its at 100% load for an extended period of time.

    I have made an IHS removal movie !!! I will upload it tomorrow for those who are interested.
    But it isn´t so difficult, just used an razor and cut around. About 15 minutes of work.

    The 65° C of course are under 100 % load with linx.

    Now i can tell something about behavior with higher Vcore.

    I raised vCore from 1.32 V to 1.44 V. Temps went up from 65°C to 73°C (also raised clock to 4.8 Ghz).

    Ivy bridge for me now behaves like sandy bridge did. Temps are near the same. I can push cpu now about 200 Mhz further with higher Vcore and lower temp.

    I think 4.8 Ghz is the Wall for my CPU..........anyway, so it still doeasn´t clock so good like Sandy bridge.
     
    Vargtass and Dent1 say thanks.

    not trieng to be a dik here.....but your temps will drop if you re install that heat spreader with a proper tim!!!

    Ivy isn'y Sandy; expecting similar stuff from an entirely differnt process is well...um...yeah...


    Cool you get some results, to eb honest, but at the same time, I think that Intel has done the right thing. Many OC'ers will outright pull IHS, viod warranty, and all is good. Other will not, and will retain warranty, albeit while running slightly lower clocks and volts.


    Voiding warranty for 200 MHz, to me seems not worth it?

    Quick question, for an air heatsink cooler, can you just remove the HIS, reapply the paste, and put the heatsink over the exposed CPU or do you have to use certain heatsinks / do something else?

    any heatsink will do, but IHS shoudl be repalced after using new TIM. Surface tension of the paste and pressure from retention bracket should keep IHS in place.

    As posed in a previous post by someone else over warranty, I am presuming everyone doing this doesn't give a hoot about any warranty? I have never personally had a CPU die (don't OC or anything personally), so maybe it's not a real worry?

    I have been playing with a i7 3770K for about 18 hours now. Somethings I've noticed with temps....

    The temps don't seem to be helped all that much with Water cooling. (this I don't quit Understand) for example I am running mine @ 4.5 Ghz 1.17v to 1.18v and I get 67c hottest core during Large FTT Prime and 71c Hottest core during 20 runs of LinX. (The rest of the cores are in the high 50c's and 1 low 60c's)
    It seems with a good Air cooler people are not experiencing that much higher temps... then what I am getting at similar clocks and voltages.

    Some good news I noticed is... while playing Metro 2033, BF3, and Crysis I saw the hottest core get up to 40c. (Other cores were in the mid to upper 30c's range) So while these Cpu's do get hot under stress testing they stay rather cool under normal gaming usage even overclocked.

    So I just thought I would throw this out there.... I have tried re-seating my CPU block several times.... I am using a high end TIM.
    The reason I am bringing this up is Because I don't know if I believe these temps are only related to the TIM under the (IHS) or not. Sure I believe that removing it will help some what... but it would on most CPU's.... so would lapping the CPU.
    I think that we are all just going to have to face it.... and realize that Ivy Bridge is a warm running CPU.
    On the other hand.... it sure would be nice if Intel would change the TIM being used and do a recall. It would for sure help somewhat!

    If I decide not to sell this CPU.... I might try taking off the IHS for my own experiments.... but i am not sure about that yet.

    BTW... Does anyone know if Intel released a Tcase temp for this CPU yet?

    Yes, it's in the Whitepapers for 3rd Generation Core i5/i7 CPUs on their site.

    I can say that the tim under the ihs is the main reason for high temps. With ihs i never would push 1.44 V on core cause temps would go fastly above 100 °C.

    Without ihs they are at 73°C and that is similary like other cpus i had (q9550, i7 920, i7 950, i7 2700k)

    I dont think replacing cooler, more pressure, better tim etc. will help. I tested all and nothing helped.

    I just waited that someone proves that tim is the reason for the heat and not cpu itself.
    As i read the news, it was clear that i have to take ihs off and im happy with it.
    I would do it again..........especially cause summer comes and temps are getting hotter here.

    Until there is proof that the high temps that Ivy reports are affecting stability or the lifespan of the CPU, then I might have interest in any of this, but as it stands, Sure, it allows for lower temps, which then allow for more voltage, but I've yet to ehar that it's helped anyone get more with the same voltage!!!


    Like, what is these chips are fine @ 90c and 1.25 V for 5 years? and what if 1.3V will kill CPU in 18 months no matter the temps....removal of IHS may actually give false security that may lead to many dead chips in the future....

    How? Reinstalling the IHS means you have two layers of thermal interface, as opposed to just one. It's nothing but a metal plate, so you might as well seat your HSF/waterblock directly on top of the CPU.

    I honestly can't see how:
    CPU -> TIM -> IHS -> TIM -> HSF

    can be cooler than:
    CPU -> TIM -> HSF

    You cannot use retention bracket with IHS removed, which makes it hard to give CPU correct pressure. It is also not quite that easy to get even pressure across the core when using block mountings. With very careful block palcement, it could be better, for sure, but it's much easier to just replace TIMM, put IHS on top, and crank it down as far as it will go..with no fear of cracking the core.

    I'm a little disappointed they used thermal paste on these, because anyone who deals with older builds and early lidded CPUs (P4/Athlon 64) knows that they definitely run hotter the more they've aged. I'm pretty sure all my old Northwoods and Athlon 64s idle around 50c but I haven't done any real testing with those recently.

    there is nothing to be disappointed about, the phenom cant beat the 3770k in any benchmark anyways lol

    I'm not surprised. Look at the stock coolers that come with intel processors. Absolute garbage. You pretty much have to replace them.

    65c "under load" is totally normal in this day and age imo.

    Unless I'm reading this wrong with the translator

    This is on AIR

    A Ivy-Bridge 3770K 4.6ghz @ 1.2V = a Sandy-Bridge 2600k 4.8ghz @ 1.4

    Doesnt sound that out of the ordinary even with the temps
