Read my other post about in depth step by step guide. Just showcasing video here.

Finally did it – Noctua NH-U9S in an Acer Nitro N50 (i5-1440F, RTX 4060, 2-slot RAM) and it works great!

So I’ve been wanting to swap out the stock cooler on my Nitro N50 for a while now and I finally pulled the trigger. Couldn’t find a single video or post about doing this on the 2 RAM slot variant of this board so figured I’d share in case anyone else is in the same boat.

What you need:

1.	Noctua NH-U9S (comes with everything except the M3 screws)

2.	M3 10mm screws – don’t waste money on those $19+ 500-piece kits on Amazon. Just walk into your local hardware store. I grabbed a pack of 5 from HomeHardware for $3.99, that’s all you need

3.	Phillips head screwdriver

Steps:

1.	Unplug your PC completely before touching anything – don’t be lazy about this

2.	Unscrew the two black screws on the side panel and take it off

3.	Remove the 4 Phillips head screws holding the stock Intel cooler, unplug its fan header from the motherboard, and pull it out

4.	Clean off the old thermal paste from the CPU properly

5.	From the Noctua Intel kit, press in the 4 black standoff risers where the stock cooler screws were

6.	Attach the mounting brackets using slot #2 on the brackets, secured with your M3 10mm screws

7.	Apply a pea-sized dot of thermal paste (the one included with the cooler is fine)

8.	Slide the fan off the cooler with your fingers – it just clips off, easy

9.	Before mounting, check orientation – I have the fan facing towards the RAM. Check my picture

10.	Place the cooler and tighten the spring-loaded bolts with the included Allen key, alternate sides evenly

11.	Clip the fan back on – make sure the sticker side faces inward (not visible) and airflow is going into the heatsink, not exhausting from the ram side

12.	Plug the fan cable into the CPU fan header on the motherboard

13.	Put the side panel back and screw it in

Results so far:

CPU temps dropped somewhere between 25°C–30°C and GPU temps are down around 10°C as well which was a nice bonus. Still need to do more testing but first impressions are solid.

One thing – don’t overtighten anything, go slow and easy. You don’t want to crack the motherboard or strip a screw. And seriously, keep the system fully unplugged the whole time.

I haven’t added any front intake fans yet, honestly doesn’t feel necessary right now.

Hope this helps someone – like I said there was nothing out there specifically for the 2 RAM slot board version of this case. Happy to answer questions!​​​​​​​​​​​​​​​​
