    Hello there me again, Ive got some screws but they are m3x16, are they going to be too big or will they still work?? Very hard to get any from where I’m from,

    any help will be appreciated:)

    I can't remember the specifics of the mounting system anymore. Sorry! You can try using what you have. Basically what can happen is either of one these two:

    1) If the longer screws can go through the mounting bracket (metal plate on the other side of the motherboard under your CPU), there's no problem.

    2) If the screws bottom out (in other words, you can't tighten them all the way), the contact might be too loose or even nonexistent. This would naturally cause high temperatures. In this case you could try using washers and make the screws shorter so to speak.

    If the screws are too long and fail to provide good enough contact, you'll notice it soon. The cooler may even wobble or rattle on top of the CPU if you twist or pull it a little. Don't use force! If there's no movement and the cooler sits tightly, it should be safe to power up the PC.

    Just keep an eye on the temps. If the fans start to run at full blast while the CPU is idling, you have a bad contact.


    Good luck!

    Hello me again, I feel totally lost again, I’m at my pC ready to install this cpu cooling fan the NH-D9L, about to follow the steps from the original post and basically it’s a totally different set up, everything is so different, I’m at a loss because now I have no idea what to do :( I can’t find any tutorials on how to install the fan either.

    Also I’ve just watched some on YouTube and I need to take the motherboard out of my PO3-630 Which I don’t know how to or if it’s even possible, I’m quite upset I wish I bought the U9S, if anyone can help my problem please let me know :)

    You don't need to take the motherboard out with that Noctua, you just have to use the slightly different length screws.

    The process should be pretty straight forward. The pictures in page one should help a lot. Like Billsey mentioned above, there's no need to remove the motherboard.

    If you can, could you take a few pictures of the cooler and what came with it? If you have already removed the original cooler, take a picture of the surrounding of the CPU as well.

    Although I found this guide late, this guide will work for the Orion 5000 PO5-640. I did have to get the extra screws of Amazon which is apparent now reading through. I ordered a pupu platter of screws and used the M3 13mm but am sure 12 or 10mm would work also. With a Plagues Tale Requiem max settings temps went from 85-87c with peaks in the low 90c to mid 60s low 70s.

    Thanks so much for writing this up! I have had a similar issue since buying my Predator Orion, very hot CPU while gaming and obnoxiously loud fans. I bought the same Noctua cooler mentioned here and was a bit flummoxed by the different setups, but I followed your simple instructions here and got it installed! CPU temps while gaming are still quite high (around 60 Celsius) but this is with the fans set to auto which seems relatively gentle, and it drops faster when the fan speeds are ramped up.

    Thanks again!
