Installed heatsink incorrectly. HELP?

So I put down the thermal paste on the CPU and placed the heatsink onto it. One problem. I FORGOT TO MOUNT IT TO THE MOTHERBOARD IN MY STUPIDITY!

Sorry for excessive caps, I'm kind of panicking.

Any way of mounting the heatsink to the motherboard without removing the heatsink?

  1. So you did not install the backplate or something or just did not lock it down?

    The stock heatsink thermal paste should not have come off from this, just remount it as needed.

    Stock coolers should not need anything fancy, just clip that sucker on.

    If it was a tube of paste, it is best to clean and redo it then install the cooler.
  2. Just remove the heatsink, clean the paste off, reapply the paste, and install it.

    Big problem. It's not stock thermal paste :*(
    It's not a stock heatsink, either.

    UPDATE: Wait. Do you mean I can take out the mobo with the heatsink still on?
  4. so remove everything and reinstall with new paste. Simple.
  5. I remove and install motherboards with heatsinks on all the time.

    How exactly is the heatsink not installed? did not bolt it down? got an image of what you have done by any chance?

    Yeah, not bolted down.

    So the backplate is not on so you need to remove the board?

    If you have spare thermal paste just remove clean, take out of the board install it all with new paste and put the system back together.

    Pre-applied thermal paste on some coolers can be removed and placed back on again if the system has not been warned up yet(not used yet).

    Do I even need to mount this heatsink onto the mobo? It's a GeminII M4 being mounted onto an FM2A75 PRO4 and the holes where the four mounting things should go are covered by large screws.
  9. Those large screws are for the stock backplate. That backplate should be replaced with the included cooler master one.

    The coolermaster backplate is universal and has to face the right way for AMD users.

    It is important to use the included hardware to mount the cooler. Since you have a tube of thermal paste, you should be able to just clean up get everything ready and then use new paste from the tube(it has enough paste for multiple installations for sure.).

    I actually have a Geminii S in my media center. works quite well.
  10. Doesn't matter. I accidentally broke the heatsink in my frustration
    :(
    Maybe I shouldn't be building a computer. Why didn't I buy a PS4 instead...
  11. What did you break? coolermaster sells spare parts.

    You may even be able to macgyver something to make it work.

    At the least, you can use the stock cooler right?

    Stock cooler fitted :) But now I have another problem. An ATX POWER SUPPLY (CX500M) that won't fit in a FREAKING ATX MID TOWER CASE! (Thermaltake Commander MS-II Snow). There is a black piece of metal welded near where the front of the PSU would be that is preventing me from pushing it in all the way. Any suggestions?
  13. Can i get an image of this part of the case. I have never seen a small power supply have fitting issues. I know I could not use my bottom fan mount of a case because my power supply was 180mm long(but that is over-sized).

    This guy somehow got his PSU to fit in the same case.
    No idea why I can't.
  15. The HX1050 is even bigger than your power supply. I think you need to take an image to show us what is in the way.

    Problem solved. There was a piece of metal screwed onto the case that may have been meant to hold Micro-ATX PSUs into place. I unscrewed that and the CX500M went into the case just fine.
  17. Not actually such a standard as MicroATX for power supplies :). Many call SFX power supplys MicroATX.

    Very strange to see such a case come with anything to hold SFX units.

    SFX bracket.
