    Hi,
    Hoping someone can help me. I have been searching for a couple weeks but not finding any solution. Any help is appreciated.

    Having high CPU temp spikes on low load (30%) with temp spikes of 40 degrees. CPU usage is all over the place with extremely high spikes just using firefox. At times I can see one of the cores taking more load than others. The temp spikes quick seconds then drops and repeats. This gets particularly bad if HWinfo fan control is used.

    Also GPU SLI is disabled yet the disabled GPU1 temp is running 61c with with its fan running constant. The GPU0 being used is running 55c with intermittent temp spikes to 63c since bios update. Both GPUs and CPU are at default clock speeds. I have not gamed yet because of this issue.

    Mouse also jumps across screen at times. Slow response from opening windows or typing at times (desktop folders or firefox window may open with white screen then fill in a second later, typing is lagging). Upper right keyboard by touch panel hot to touch.

    My system specs and what I've done to date.

    Alienware M18x R1
    i7-2630qm
    580M SLI bridged
    NVidia catalyst and drivers v388.43
    SSD drive and standard HDD
    Win7 Pro

    Changed from Dell A05 BIOS to Unlocked Bios A04 (temps did get a bit better was running idle near 70).
    Repasted CPU and GPUs with HTNoctua-14 and .5mm pads.
    Cleaned minor amount of dust off heatsinks and fans with compressor and soft toothbrush. (was surprisingly clean when first opened)
    Running HWinfo for monitoring with EC monitoring disabled in app.
    Lappy sitting on 5 fan cooler. Moving lappy around cooler to make sure its not blowing hot air back in vents no difference. Cooler fan control up, down no difference. Off gives noticeable heat increase at least 10 degrees.

    Nothing stands out in device manager and all scans of hardware report no errors.

    I am not sure what paste that is. I have not heard of it before and nothing comes up on a Google search. I have used NT-H1 before and it is one of the worst thermal pastes I have ever used. Otherwise, It seems like you have done all of the right things. Please try some IC Diamond, Kryonaut or Phobya NanoGrease Extreme thermal paste and see if the temps are the same. Since you are trying thinner thermal pads (a good idea as long as they are still thick enough to make contact) when you take it apart, look closely at the thermal pads to confirm all of them are being compressed. If you still have a single pipe CPU heat sink, see if you can get a two- or three-pipe M18xR1/R2 CPU heat sink on eBay. With the stock one-pipe heat sink I always had higher than acceptable CPU temps with the 2760QM CPU no matter what thermal paste was used. The system is old enough now that the heat pipes may be losing their gas charge and not cooling as well.

    A higher CFM CPU fan (J77H4) is also available, and it does help. Notice the CFM on the J77H4 is 11.7 CFM versus 4 CFM.

    Thank you for responding.

    I have had this all of two weeks and am about to loose my sh*t, lol.

    It is Noctua H1 paste that I used. I will re-paste with another. Of the three pastes you mentioned which is the better one? should I go with a 1mm thermal pad? The heat sink is two pipes. There was thermal pads on the pipes, which I removed. It seemed to me that pads on the pipes would block flow of heat dissipation. The fans look original. If the CPU thats in it runs higher than normal by design, should I change the CPU? if the CPU were to be changed is there one you would recommend?

    You're welcome. Sorry nobody else had any suggestions, but maybe those other folks that know their way around the M18x have not seen your post yet.

    I would say Phobya NanoGrease Extreme of those three. The best CPU options available for the M18xR1 are 2920XM or 2960XM, but I would try to get those temps under control first. If you can get a three-pipe heat sink, do so. Then if the temps are good you can look for an XM CPU and 11 CFM fan on eBay.

    Leaving the pads off the CPU heat sink was a good choice. Even Alienware stopped using the pad on it because it caused problems.

    Using 0.5mm pad on the GPUs is fine as long as they are making good contact. If they are, thinner is better. If they are not, then the 1.0mm pad would be better.

    I repasted with IC diamond 24 carat and also fixed the pads. I am still using Ahmeds A04 BIOS and HWINFO64. Temps did drop and all was good...for awhile. However I am having a variety of problems now.

    I am getting a roughly 30 degree temp difference between the 580m card being used which is generally running at 35-45 idle (HW reporting) and card2 that is SLI disabled idling at 60 degrees. I am running PHYSX on card1. HW fan control is a one off, fan control limits are locked at 2000 and 3800, fan controls are set to auto custom sometimes the fans will come on high and then just stop 2 seconds later, sometimes they are not activating at all as they should.


    As of this morning I only have control over 1 fan in HWINO the other two are greyed out.


    I am also getting ACPI events 13 and 15. Event 13 with the battery in and 15 with the battery pulled. I have experienced 3 shutdowns, which may or may not have been attributed to hibernation being activated. I have since deactivated hibernation.

    I am also getting cursor jumping and minor latency when opening files or windows.

    All hardware scans in support assist, BIOS, sfc and minor benchmarks come back passing and nothing stands out in device manager.

    Virus scans with adwcleaner, hitmanpro, malwarebytes, avast, superantispyware and esetonline come back clean also.


    I am running Nvidia Cntrol panel v388.43

    My question is...could card2 be going bad? maybe the temps are actually higher than HWINFO is reporting which may account for shutdowns and minor latency?

    Is there a better version of the BIOS that may fix the acpi issue?

    Is there a better version of Nvidia catalyst and drivers than the one being used?

    can you point me to where I can reset HWINFO to have full fan control and not have a lockout limit.

    Yes, you could be having a hardware issue. It is a small miracle that your 580M cards have lasted this long. That's pretty amazing. You might try removing the slave GPU to see if the issues go away. If things return to normal, that would definitely pinpoint the problem as the slave GPU. Normally, the master GPU dies first. So, if removing the slave does not fix it, try removing the master GPU and using the slave in the master MXM slot. Or, remove both and see if you have issues running off the Intel HD Graphics.

    You can try uninstalling HWiNFO64 (confirm all folders are deleted) and use a registry cleaner to remove all of the supporting obsolete keys from it, then unzip a new portable or reinstall. I always use the portable version and prefer that. Enabling EC support increases fan control, but comes at the cost of some things like DPC latency and random glitches (freeze on shutdown was one I can recall).

    If one of the cards are failing even though scans are all passing I know that could cause a TDP shutdown but would that also cause event IDs 13 and 15? or are the events more a software setting?

    Also, do you think disabling card2 in device manager help to rule out if its failing in lieu of a teardown to get the card out?

    I remember before installing the Nvidia 388.43 catalyst drivers device manager was not reporting Intel HD on board.
