Q9550 Temperatures.

Hi guys, could use a little help here as im scratching my head at the min.

So got a q9550 on a asus p5q deluxe MB with this fan on it. http://www.jimmspc-store.fi/tuoteinfo/CPAF-004?pid=1302455942358. Im using arctic silver 5 paste. All this in a gigabyte aurora 3D case.

My system temp is 43 on idle.
Now im struggling to get decent temperatures on this thing.
So on stock clock idle with real temp im getting
C1 44
C2 44
C3 44
C4 45

And on using prime 95 im getting

C1 61
C2 61
C3 60
C4 64

Now bear in mind this is at stock speeds of 2.8Ghz.

I upped the FSB to 353 to hit 3Ghz and was getting into the 70s under prime so dropped it back down.
Reapplied paste, reseated fan and checked heatsink and all appears good but looking around on google it appears people are getting much lower temps than me and obviously im not going to be able to clock it up to 3.6ghz with these temps. My modle of CPU is the C1 version but would that make all of a difference.

Any ideas guys? Really could use some help.

  1. You might search around for problems associated with faulty Digital Thermal Sensors (DTS). Search around these forums. The subject has been discussed at length


    Also Randomizers guide.

  2. Thanks for the quick reply badge, even tho iv done some searching this is the first iv heard about faulty sensors being a huge common problem. If my sensors are faulty how am I expected to safely gauge any overclocking i would like to do? And how can i know for sure they are faulty?
  3. I have the P45 ASUS P5Q deluxe running with a 65nm C2Q 6600 and have no temperature issues. On the other hand I have an ASUS P45 P5Q Turbo MB running with a 45nm Q9450 and have the same situation with high CPU temps. I RMA'd the CPU as well as the MB and still have about the same high temps. The Q9450 ran much cooler on my ASUS x38 MB. I attribute the high temps to the combination of the 45nm C2Q on the P45 chipset. If you have a 65nm C2D/C2Q try it in the board see what temps come up. This has been my experience. Crazy thread, but discussed here ;)

  4. Badge could i ask you a favour mate,

    Do you have your p5q with the q9450 in it overclocked? If so what speed and temps you getting?

    Also being as tho we have the same have the same set up almost if yours is OCed what setting are you running it on?

    Thanks pal and ill be sure to check out that thread!
  5. I have the Q9450 in the P45 ASUS Pro Turbo. It's currently a backup machine and used sparingly, but I keep it updated. I used speedstep. Idle temps look amazingly like yours as posted.

    C1 44
    C2 44
    C3 44
    C4 45

    This is the new retail box Q9450 I received from Intel when I RMA'd the original. I used the original Q9450 in my X38 and no heat issue with the processor. Only after I installed it in the P45 board did I get the temp issues and the subsequent RMA of the processor.

    EDIT remember I currently have a 65nm Q6600 installed in your exact MB with no temp issues. Also I have a Q9550 in my X38 and no heat problems. Speedstep with OC to 3.2GHz.
  6. Hmmm interesting stuff. Thing is im more confused about what to do now than I was before hehe. Funny thread by the way :)

    Cant RMA now as everything is too old and not sure if its worth buying a better fan/heatsink to see if that helps.

    I guess ill just run it on stock as at least the temps are stable if a little hot but im a bit gutted i wont be able to OC it as thats one of the reasons i chose this CPU.
  7. The temps you have are still fine. I get very similar temps using my 45nm Q9450 on a P45 chipset. However, if I move that processor to my x38, the temps come up cooler. If I use a 65nm Q6600 on my P45 the temps are much cooler than the Q9450. Just my experience with the whole thing.
  8. Just wondering. Checked my settings again an mt vcore is set to auto. Think this could be the cause of my high temperatures perhaps?
  9. Naw, been there. If you have a different motherboard try installing the Q9550 and check the temps.
