    This is only my 3rd build, so please be kind (but brutally honest)...

    I started having some thermal shutdowns unexpectedly on this new build:
    MB: Gigabyte GA-p55m-ud2
    CPU: CORE i7 Lynnfield 2.8Ghz (stock cooler today)
    RAM: 8GB (4x2GB)
    OS: Win7 Pro (64bit)
    Vid: GE Force 9500
    Case: Antec Mini P180 (microATX)
    Power: Corsair tx750

    I admit that I did not run a temp check upon build completion and have been running for about a week... I beleive that the temps in the first test below have been consitent since the build, but can not be certain...

    I can achieve "normal" operating temps by running the CPU at 2 Ghz (failsafe BIOS)...

    I am looking for input on how to able to run the CPU at rated speeds or better and still run well below 60 degrees C MAX in the cores.

    The following images tell the story...

    RealTemp Test Results (Prime95: Small FFTs)​


    TEST # 1
    (CPU Overclocked to 3.3Ghz)

    TEST # 1b (confirmation)
    (CPU Overclocked to 3.3Ghz)

    [​IMG]

    TEST # 2
    (Bios Settings at “Load Fail Safe”: CPU @ 2Ghz)

    [​IMG]

    TEST # 3
    (Bios Settings at “NORMAL”: CPU @ 2.8Ghz per specs)

    [​IMG]

    SpeedFan Info from Test #3 above:

    First Attempt at Thermal Grease…

    Any input at all is welcome... Happy to provide more info if needed...

    I am planning on replacing the OEM heatsink/fan and suggestions are welcome (1156)

    Thanks a million in advance!

    the advice is not to OC. since the first days of the I7 overclocking thread the general consensus is that OC'ing an I7 on stock cooling is suicide and for people with alot of money to blow on cheap laughs

    I need a counter for everytime I say this:

    Don't use the stock i7 cooler. Get an aftermarket cooler.

    Not having built a lot of these, you probably didn't know that yet. :(

    But also and furthermore you should get that paste off and reapply with something like Ceramique.and get you an aftermarket cooler like a V8 for example.

    Thanks! Great replies!

    I would be happy to run "rated clock" on upgraded cooling if I can keep the cpu below ~50C in heavy loads... Doable?

    Right now, I am hovering at 45C at idle when running "Stock"...

    Unless you're doing something serious like b.o.i.n.c.i.n.g. (yes, I actually said that) at 100% usage you probably don't need to worry about the temps with an aftermarket cooler that much.

    If you do, then water would be a better choice.

    Your gonna need watercooling if you want 50s on load. Even the best cant keep most i7s under 70 at load, mine doesn't.

    these run a bit warm on the normal but you are best to stay out of the 90 arena;) you can do a couple of thing till you get a good cooler....start with running with the side panel off...get a fan blowing toward the open panel on the case ... get some paste and redo that paste job in the picture.... you should be better with that till upgrade but plz do watch them temps.:toast:

    the best way to keep your temps down for now before you get a really good air cooler (and dont misunderstand you need a really good air cooler like high end xig/noctua etc) is to put some thermal paste on the proc (after cleaning it) and take a credit card or put your figures in a ziplock or something. and evenly coat the entire proc. then carefully reapply the cooler making sure you maintain even pressure until the cooler is locked down.

    The CPU should not be getting that hot at stock speeds with the stock cooler if it was attatched properly. If you believe the cooler is installed properly and you are getting those temps, I would contact Intel as those load temperatures are unacceptable. You should not have to get an aftermarket heatsink for your CPU to run at acceptable temperatures.

    They are not erocker, his "Load Fail Safe" run shows it's maxing out at 62 at stock. Edit, saw the 2.8 run and that is very hot! ouch! :eek:

    Edit, I believe his thermal paste may be a bit of a problem.

    OK! Thanks a bunch to all!

    My Plan:
    Get a good quality aftermarket cooler... (thinking Thermalright MUX-120 with 2-120mm fans)
    Reapply Paste properly... (I am sure that this is at least part of the issue)
    Accept that 70s at FULL load are probably the best I can expect...

    I will report back once installed!

    Thanks again!

    i disagree at 100% load on I7's temperatures in that ran on stock cooling and speeds are easily attainable depending on case flow. especially if you are loading all cores at 100%

    The stock cooler isn't great, but 90°C definitely isn't right, and from the looks of that thermal grease, you are using waaaay to much.

    Under 70°C under load at stock settings with the stock cooler@100% is doable. Under 60°C probably isn't, and I don't think even the best air cooling can keep them under 50°C.

    Part of the problem might be that the motherboard is overvolting the processor by default, go into the BIOS and manually adjust the CPU voltage. If speedfan is reading the VCORE properly, 1.58v seems WAY high to me for stock speeds. The last i7 I put together I think the default vcore was something like 1.1 or 1.2v.

    I don't like how the paste contact looks in the picture for sure...reaply and bet things improve at stock.

    So you are saying the cooler that comes with a new CPU is insufficient to work at it's rated speeds? Not acceptable. Case airflow should not have to be anything spectacular. I don't buy a new car just to have to put a different cooling system in so it will work properly, any other piece of equipment shouldn't be any different. Especially a CPU.

    Intel's CPU'S are rated at a tolerance levels of ambient heat too.

    Looking at it, I agree. It looks like one or two pins on the left of the CPU picture weren't mounted correctly as the paste is barely spread out.

    the processor is operating within TJ Max that being the case their isnt anything wrong (in intels eyes) with those temps. personal preference has nothing to do with rated temperature acceptence.

    I think a CPU-Z screenshot is in order. SpeedFan doesn't always show voltage correctly.

    *I'm pretty sure 98c is above Intel's TJ Max.

    TJ max is in/past 100C for i7 i5

    Well, cutting it a bit close for my comfort. I know damn well, if everything was mounted correctly and I got those temps it would be back to Intel with it. I really don't care what TJ Max is, 98c is too damn hot. But, whatever that's what I would do. Besides, the CPU could be throttling at that temperature regardless.

    OR MAYBE NOT.....
    •Two separate thermal chambers, with the bottom mounted PSU having direct access to outside air in order minimize the heat through it and thus keep its fan from speeding up.
    •The main chamber has two exhaust fans, a 120mm fan on the back panel and a 200mm fan on the top, directly over the motherboard area. The latter obviously dominates as its airflow will easily be three times that of the 120mm fan.
    •It's the , combination of the large top mounted fan, the extra internal partition, and the need for some space for the PSU fan to breathe
