PO5-640 with an overheating question? My temps are high 90c+

@Ol_Snapper It comes with a new tube of thermal paste, only thing you will need is the screws. The youtube videos will make it seem more complicated than it is since you can use the OEM backplate. Have faith, you got this!

@Ol_Snapper I used this guide: https://www.youtube.com/watch?v=t8-o9m-OP3E

You do not need to remove any major components. I was able to get it installed without removing my GPU. You'll have more space to work with if you do remove the GPU, but it is not necessary.

MOBO removal not necessary at all, you'll skip straight to the bracket installation on the OEM backplate. This is where the additional M3 screws are going to come in, making everything much easier.

Spacers over OEM backplate -> brackets screwed on with M3 screws -> thermal paste and cooler tower screwed onto brackets. Best part is you'll come out the other side with a much better understanding of your machine!

So I think I am willing to give this thing a try! Again, I won't be purchasing the Noctura NH-U12A until Black Friday, so I have some time yet. I have a few lingering questions.

1) Since I will be using the 10mm M3 phillips screws to install the mounting brackets, I will not need or have any use for the nuts that come in the Noctura mounting kit?

2) When I am removing the stock CPU cooler / heatsink, anything special I need to know? The cpu chip won't rip out of its socket when I yank that sucker out? lol

3) What do I do with the stock cooler power cable after I unplug it, along with the aRGB cable? Based on the user manual pictures it appears the wire is threaded behind the mobo?

4) I would like to utilize the extra stock fan as an exhaust and mount it directly above the Noctura (top left). Can anyone help explain how to do this (mounting kit, where to plug in the power cable, etc.)?

Thanks!

@Ol_Snapper

1) You will still need some of the Noctua hardware, the only difference is you'll be using the M3 screws to attach the Noctua mounting bracket to the OEM backplate on the mobo. Everything else is the same (the Noctua cooling tower has captured screws, so its pretty easy to figure out how to get it mounted). Keep all unused hardware as you will use it to install the old Frostblade fan in step 4.

2) The old cooler/heatsink came right off for me, but you may want to do the install after running your computer for a bit to heat up the thermal paste and prevent any sticking. If you're waiting for Black Friday, you'll probably need to run your computer to heat up the CPU as the paste will be pretty old by this point. Noctua includes new paste with the cooler.

3) You will need to snip the ziptie holding the power cables together that is running through the slot behind the mobo, and once it is snipped you can disconnect the power/RGB cables from the mobo and gently pull them out. Actually snipping the ziptie may be the hardest part of the entire install (still not too hard), so make sure you have a decent pair of long nose snips.

4) I used the screws that were mounting the OEM cooler (the screws I replaced with the M3 screws) to mount the top fan. You can use the nuts included with the Noctua as backers and the holes for the fan are already drilled into the top of the case. There are a few extra fan ports on the mobo, and you can plug it into the original RGB port as the Noctua does not have RGB so that slot will still be open.

5) Predatorsense will still control all your fans and give you accurate readouts of speeds.

ok patches one question nobody has asked u that i see is where on the MB did you plug in the noctua fans at? I'm going to be ordering this soon and installing it i notice 3 open fan slots up near the top looking at pics others have provided of our MB what one did you use? and i noticed from your pics you mounted the frost blade fan to the right upper slot and someone else did there's right above the cooler why did you choose the right side instead of the left side over the cooler? and do you think it matters lol and thx for all the help you have been great helping us out who haven't done it yet. ok its ordered and will be here Monday !!@!!

ok but I'm confused if I'm putting the CPU fan up top for intake or exhaust then were would that plug into? and i assume that's in # 4 now? i guess i can open up my case and look but i was asking patches because he just did this. and i want to know exactly where he plugged both fans into.

ok cool thx if it comes Monday like amazon says I'll be installing then ill post pictures etc for you all and thx for being so helpful. i guess the only thing i need to make up my mind on is do i put the frost Blade fan to the left over the cooler block or the right side away from it. I'm going to try both and see what one is better. I'm thinking right over it as an intake pulling in cold air on the block that makes more sense to me but I'm going to try every configuration possible lol.

sure, thing buddy I'll do before and after pics for you tc.

yeah, billsey i am going to put it up top.... i guess then it's considered a case fan...so where do i plug it in at? i don't see an option to connect another case fan. I'm assuming everyone else just plugged there's into slot 3?

@chugzilla That would seem correct to me based on the pictures. I thought I read on here somewhere that you have to uninstall and reinstall PredatorSense to get it to recognize the Noctura dual fans and extra case fan setup..
