5.0 out of 5 stars Works great

P. · August 24, 2024

I don't want my PC case to be a disco nightclub like all these new coolers offer, it's a waste of power and distracting. This cooler fit well and was easy to install, it even includes thermal paste. So far it's quiet and cools my Ryzen well.

5.0 out of 5 stars CPU temp went from 50 / 80+ down to 30 / 40 😮!! (NOT a gamer)

I usually wait a while before coming back to review a product, to see how things work out over time. This time I'll make an exception ...I have a i3 Skylake build for my home office. My CPU monitor was consistently pinging me that my temps were going over 80c under normal use...under idle, it usually hovered around 50 to 60. The case was free of dust and temps in the room were always not nearly hot enough to explain it.Opened my case up yesterday to install a new vid card and decided to also get rid of the original Intel fan and get a better solution. I searched Bolo and this option popped up on top of the list. The reviews and feedback were so good I only scanned a few other options before coming back to this one and pulling the trigger. Same day delivery was an added bonus!Installation is a bit of a project, but nothing anybody with a bit of experience with this kind of thing can't handle. On most mobos you will need to remove the whole board to get the included mounting bracket on the back. As a bonus its nice they include a (necessary) long screwdriver for the main mounting screws, and some quality thermal paste. The entire kit is very solid, quality materials.I mounted mine so the fan directly faces the rear fan in my case. That way the cooling fan pulls air through the block across the CPU, and the rear fan sucks it out the back of the case. Super quiet I hardly know its even on.I recommend searching YouTube for tutorials, I found a couple of guys that walked through the details of how they got it installed with minimal hassle and no errors. Always a huge help and makes it go that much smoother.Immediately after installation I booted up and checked the CPU monitor. CPU temp now hovers under 30c (27 / 29) at idle. In fact, with about 10 Brave tabs open and normal clicking around / typing, its *still* right there at the same temp. Does not even rise at all! Running 3 YouTube videos in separate tabs ... still does not even budge.I haven't tried any rendering or anything that seriously taxes the CPU yet but for normal every day use this thing is doing its job like a champ! Can't speak to long term use but based on all the positive reviews I'm confident its most likely going to continue to do so!

5.0 out of 5 stars Impressed, media center PC

A. · January 21, 2025

I recently did a "hand-me-down" "upgrade" on my Media center PC putting in a 9th gen I5 and a GTX750. Previously it was cooled with a AIO but you could hear the pump noise. I put it together at first using a stock intel cooler. Which was loud. As it doesn't need a lot of graphics power it has a old GTX750 in it. It is well below the minimum specs of flight simulator 2020 but I loaded it as a test. Using the stock cooler the CPU was hitting 100c and it would never load. With this cooler it stayed around 50c and actually loaded and played it fully stable for a few hours (some just letting it run on autopilot) Honestly impressed in the performance for such a small quite cooler. With 2 120mm Noctua case fans and everything in the quietest fan profiles it is nearly silent under nominal loads which was my goal. Using zcpu load test the temps stayed low.

5.0 out of 5 stars My First Noctua Purchase Won't Be My Last - UPDATE 2 Years After Purchase

S.F. · March 4, 2022

My Dell Studio XPS 9100 desktop's cooler was not keeping my CPU cool - due to the well-known plastic tabs breaking on the cooler - keeping the cooler from making solid contact with the CPU. I tried to order a replacement from Dell for a perfect-working computer...but Dell no longer sells a cooler for that model. Planned obsolescence, I presume even though my XPS runs perfect in all other regards.So i checked a few aftermarket coolers that some said "might work" and after viewing some YT videos, this Noctua U9S cooler seemed to be my best option. Before, my core temps were almost "off-the-charts" reaching 90-100 Celsius regularly with very little load. After (easily) installing this cooler, my minimum core temps went from 50c to under 25c in all six cores. My maximum core temperatures decreased from over 95c in all six cores to about 55c. And the fan that comes with the cooler is much quieter than the OEM fan provided by Dell. All the positive reviews I've read about Noctua, turned out to be 100% true.To make this work, Noctua had to send me a modification kit for my Intel 1366 motherboard. I just had to provide proof of purchase of the U9S and my dell 1366 socket. Once I did that, Noctua customer support mailed me the kit I needed. Just great customer support. And my computer is now running cool and calm. Should help me get another year, or two, out of Michael Dell's computer.****UPDATE - I bought this Noctua CPU Cooler Feb. 2022. March 2024 it is still working like new. My CPU never runs hot and the fan is extremely quiet. One of the best Bolo purchases I've made in the last 15 years. Good company to work with, too.

5.0 out of 5 stars Great cooler

Fit well with my AMD 4 series cpu. The kit comes with adapters for intel chips as well. Keeps my cpu very far under the upper threshold. Takes a bit to get used to the brown fan in the case but the performance it offers is fantastic. I'd recommend purchasing another fan for optimal cooling performance.
