    Default 10% OC-ed i7-950 quickly reaching 88+ Celsius during stress

    Specs:
    i7-950 @ 3.06GHz, 10% overclocked to 3.38GHz (147x23)
    MSI X58A-GD65
    24GB @1333 a-data 6x4GB RAM (running at 1176 though)
    XTREME Gear 120mm watercooler with 120mm fan
    Thermaltake V3 mid tower
    EVGA NVidia GT 430
    120GB Intel X25-M SSD
    64-bit Win7


    I'm getting 88-89 Celsius on the processor under load and I'm worried something is wrong (I'm a hardware noob). The machine idles at 38-40.

    Longer story:
    I recently bought this box from - as far as I can tell - a reputable online assembler.
    To test the temperatures under stress I wrote a small stress program (4 threads doing numerical operations, 4 threads doing memory operations, all running in tight loop). This utility got the cores to 88-89C and I stopped it in fear to not boil the CPU. On the same test my old Core2 quad Q6600 at 2.4GHz barely got to 52C.

    I'd appreciate input to the following questions:
    1) Should I return the machine to the online assembler for fixup? As I said, I'm hardware noob and I can confidently fixup only minor well uderstood things.
    2) What factors may be contributing to the issue? I'm guessing two reasons for the high temperature could be bad mounting of the liquid cooler and poor conducitve paste application. Anything else?

    Thanks a lot for your input!

    Welcome to PureOC!

    first of all, overclocked Bloofield is run much hotter than Core2; 130W TDP, 4 cores, 8 threads vs 65-95w TDP, 2 cores.

    I see you are using water cooling, the obvious that cooler cant handle the overclocked i7 PERIOD!
    So nothing wrong with the hardware but except the watercooling gear.

    Can you post the image of the watercooling gear, cause I never hear of that brand.

    Thanks for your replies, Deton and Drdeath!

    The picture of the cooler is in http://www.cyberpowerpc.com/spec/get...t%20at%2020dBA.

    Deton, I read your statement "... obvious that cooler cant handle the overclocked i7 PERIOD" to mean "this particular cooler can't handle the OC-ed i7, however sufficiently cooling an OC-ed i7 is not lost cause if the cooler is changed". Is this a correct read of your statement?

    Can you recommend a well-known-good cooler for i7 ("good" = "sufficiently cooling" + "fairly silent")? What are good target temperatures in stress and in idle with a good cooler?

    Thanks!

    That cooler is definitely the culprit. A single 120mm rad isn't enough for an OC'd i7 IMO, and the fact that it's a low airflow fan (20dBa) exacerbates the issue.

    I dont believe the issue is that the cooler isnt enough,i believe that the cooler has serious problem possible the pump or the wb is f***ed up.I mean common 3.38.Stock coolers can handle this.The other option is to have a bad oc and the voltages are extremelly high.Try download cpu-z and post a screenshot here.

    Thanks Logan and wheelsdeal. The CPU-Z screenshot is here: http://img814.imageshack.us/img814/6...creenshots.jpg

    One data point from the BIOS, which seems as a discrepancy with the cpu-z report:
    CPU Vcore: 1.224V

    I can't really comment much on your cooling gear because I don't anything about it but what I can tell you is something really major wrong with it.

    Ok, you have speedstepping enabled which give you 1.77Ghz and its idle temp is 40C. This temperature should be for 4Ghz Oced at idle.

    possibilty problems:
    1) pump is not working properly
    2) fan is too slow for the rad
    3) poor heat dissipation (I'm bet that radiator is alluminum)

    Best air cooler can really handle Oced i7 is Noctua NH-D14, and if you want another watercooling gear then tell me your budget.

    Lets sort out a few things ...

    can a single 120mm rad cool an i7 950?.....yes. Overclocked a little?.....yes Overclocked a lot?......Not really

    The reason for the above statement? the slow quiet fan

    So if you want good performance from this then the cheapest answer is to fit a BIG cfm fan...something like a Delta AFB1212VHE 38mm but the downside is you will not live with the noise.

    The quieter you want this to be the lower the overclock or the bigger the radiator must be

    The quietest fans on the market are probably the gentle typhoons but for this you will need the 1850 rpm one they are not cheap but they do perform.

    Having said all that the problem here is that the heat is not being transfered away from your processor so we need to find out why....this can be....

    the system is all working but not able to cope (at such a low clock it should)
    there is an issue with pipework (like a kink) which is restricting flow
    the contact between the cpu and the block is poor

    Under stress do all the pipes/components seem to be the same temp? use your finger or a thermometer and check for kinks while you do this

    hey... just thought id add a crazy thought. Maybe your waterblock isnt seated properly. Maybe you put your paste on wrong or too much. One time i got it all ready to go and i had the same problem because i forgot to take off the clear plastic shipping film from the waterblock hahahaa dumb.
    anyhow... more often then not if you feel somethings wrong then good chance that youre right. id say go over everything again and make triple sure its all hooked up and working right. good luck bud.

    @Jayfunk; he didn't assemble the rig by himself, he bought it from online OEM pre-assembled rig.

    IMO, it's just a bad case of cooler. Most of this builders are still using uncapable WC kit for i7, these kit was designed for LGA775 platform and to continue to push the WC kit all they have to do is make LGA1366 bracket and just slap it on and call it a day.

    There's one way a single 120 slim rad with low CFM/RPM fan can handle Oced i7.

    Default Thanks, Deton!

    I wanted to report back the resuts so that hopefully others can benefit from Deton's advice.

    Deton, thanks a lot for your advice to replace the cooler with Noctua DH-14! This air cooler absolutely rocks. Here are the objective and subjective observations AFTER installing it:

    1) my home-grown test and prime95 never ever let the CPU hotter than 70C.
    2) the CPU idles at 30C
    3) the Noctua fan is super silent (I still can't believe how they do that with such large fans)


    And now the best part - this fan allowed me to additionally boost the machine: now the CPU is overclocked to 3.8GHz (the old fan couldn't handle even 3.3GHz). The mobo is 25% OC-ed (from 133MHz to 166MHz) and the memory is OC-ed to 1660. Again, this configuration survived 2 days of Prime95 with no crashes and not heating above 70C. Beautiful!


    Thanks a ton for your help and advice, Deton!

    @Zon; you're welcome, glad can help.

    Now, would you dare to push it to 4Ghz, if you have the right voltage then the load temp is around 72-75C
