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 Amazon 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!

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.

Comes with a bunch of screws, brackets for AMD/Intel. I had to modify mine because I didn't want to remove the motherboard. If they had just made a bracket screw that was thin on both sides, and added additional thumbscrews for that thin screw, then you could just mount this bracket without having to take apart your motherboard, because this is light enough that a front bracket can support it. Aside from that, it runs great, very cool and essentially silent. The fan it comes with is just a high quality one, and it comes with like 5g of thermal paste. It's not worth buying a thermal paste separate, unless you find some like extremely good one that's better than Grizzly. I wasted $10 on Grizzly (gonna return it) and tested the paste on the stock cooler and there was no temp difference for me, and people say the Noctua pastes are about 90% as good anyway. I added some example pics. The Handbrake picture is essentially a stress test or worst case scenario. My CPU throttles back to 3.8ghz because I'm using all these goofy Dell BIOS settings and then overriding them with Throttlestop to get an overclock. (I might have to manually adjust my machine to 4ghz or 4.2ghz to keep the temps low while encoding) You can see that 4.5ghz on low usage has great temps, 54C on 20% usage, so for gaming this will probably work very well and stay well below 75C, since you won't hit the CPU usage you'd hit while encoding. In Nier Automata for example it's staying around 60C at 4.5ghz, so pretty great. Some games may be more optimized for CPU and may push it hard. Not quite sure how they're made these days, but generally they'll all leave a certain % of your CPU aside so you can use your computer well, meaning your temps won't get crazy.

I am STUNNED with how silent this fan is on top of it's performance! Played POE2 for a few solid hours, typically with my intel stock cooler my temp would be about 145(f) while that cooler made SO MUCH noise. This one hardly made a sound and kept my temps around 120(f) with a few hotter spikes depending on game play. Install was a bit of a pain - I did have to take everything apart and unscrew my motherboard from my case to get the backplate on, which was less than fun. However, it is well worth it. Also make sure you're really following instructions based on your chip set because the screws have triangles that lock them into the baseplate a certain way depending on your chip. So yes, a tiny bit of a pain to install it, but nothing you can't figure out if you're an "I played with LEGOs growing up" kid and can follow picture instructions. If you've got a better case than mine (I do have a "back of CPU cut out panel on my case but it was offset JUST enough that I couldnt' get the screws in) you might not have to take your motherboard out. If you don't have to, then honestly, installing would be 10 times easier. If you're not comfortable puttering around inside your rig to install this, be aware that you'll need to outsource help. It's not a quick snap-into-place piece, but it truly isn't difficulty just tight space that makes it a pain
