High temperature on q9550 after changing thermal compound

Hi

My pc was full of dust and the thermal compound was very old and the cpu temperature was little high,
So I cleaned my pc then I changed the thermal compound ( it was my first time to remove the heatsink and changing the thermal compound ) anyway before I changed the thermal compound I watched a lot of how to videos.
Then I cleaned the pc and changed the thermal compound I put on the side a 120mm fan and down the case a smaller fan
So now I have clean pc, new thermal compound and more fans, but unfortunately the cpu temperature didn't get lower it became higher on idle and load which is really strange, I changed the thermal compound four times three time I put a small dot of thermal compound in the middle and the last time I put it vertically or horizontally I don't remember.
here is a pic after playing for about 10-15min

I know the thermal compound I have is not very good but it's the same one I had on my cpu for few years so it should not be the problem, I have a standard heatsink and my cpu is not overclocked
my case is cooler master haf 922

Thanks

  1. after applying the paste had you clean the heatsink and cpu from the old paste. if not that is the problem.
  2. yes I cleaned the heatsink and cpu
  3. You most likely put too much paste.
  4. I'm sure I put small paste like this:

    but I'll see if I still have paste and then I'll try again
  5. oh I forgot to say every time I change the thermal compound I look at the cpu and the heatsink and it's not too much and after looking at the tiny dot here

    http://www.hardwaresecrets.com/article/What-is-the-Best-Way-to-Apply-Thermal-Grease-Part-1/1303/2

    it's the same amount of paste I put and the same amount of paste after removing the cpu and the heatsink, so it's not the problem but I'll also try again to be sure
  6. the Intel heat sinks are a pain sometimes to seat properly. you may think all 4 pins are pushed through right but aren't. best way to do it is with the mother board out of the case. Anyways, try re-seating the pins in a criss-cross pattern.
  7. I think you are right because it was very hard to put heat sink well and I was going to remove the motherboard to seat it properly but I didn't because it's a hard job :D
    anyway I think I'll do that

    Thanks

    Swifty's got the right idea. The thermal compound itself will have a negligible effect the temps but almost always when they go up after removing the cooler its because it wasn't seated properly back down.

    Push hard. You should feel a slight snap or click.

    +1. :sarcastic:
  10. I think the 4 pin is not working well because I hear click from 2 pin and not from the other 2 I push very hard but still I can't hear any click so the only way is not remove the motherboard I hope I don't break anything when I remove the motherboard :D

    thanks
  11. removing motherboard is not difficult.
  12. I removed the motherboard and the heat sink was seat properly, I really thought this was the problem :( anyway I removed again the paste and I put new one and I put the heat sink and it was seat properly but unfortunately again the temperature was high, so what is the problem ??? xD
  13. reset CMOS.
  14. you mean from the bios I choose load optimized defaults then save and restart ?
    I did that before but the last time I didn't I'll do it again
  15. remove the cell out from motherboard then insert again.
  16. does it have side effect ?
  17. okay I'll try it.

    thanks
  18. after I did that there was option to choose from I selected default profile, I hoped it will fix the problem but the temperature is still high :(
  19. hmm, do you another cpu cooler.
  20. can I use an expired alcohol ?

    no, why are you saying that, it might damage your cpu.
  22. I already bought new alcohol so I was just asking before I throw the old alcohol :)
  23. yeah, use isopropyl alcohol.
  24. so I can't use an expired 70% isopropyl alcohol right ?
  25. use it your own risk.
  26. lol
    then I'll not use it :D
  27. do you know this paste ?

    Cooler Master IC Value V1 Thermal Conductivity Compound

    and is it good ?
  28. yeah thats one cool.
  29. I used mx-2, It's less viscous, doesn't conduct electricity and very easy to remove in case you put too much or screwed up with the amount and it's also cheap
    It's better or equal than arctic silver 5 at cooling

    there's a video of how it spreads too:
