Cryorig C7-47mm Tall, SFF Mini ITX CPU Heatsink

These are, by far, the best CPU cooler I have ever seen for this price, and I've gone through about a dozen different kinds over the years.The heatsink is solidly made and feels very sturdy, and cable is a high-quality braided sleeve, not just three cheap little wires flailing around loosely. The fan is unbelievably quiet, too, for something that performs this well; more on that later.These aren't just a simple heatsink package; Cryorig also provides you a copious amount of thermal paste, and a solid steel tool for tightening the hex nuts on the rear mounting plate. Installation is, for that matter, extremely easy, assuming you read the provided directions (which include QR codes for video demonstrations), and while the bracket defaults to the Intel LGA configuration it can be quickly converted to the AMD configuration by simply moving one screw and the mounting nut on each arm.For performance: this cooler has been tested on an i5-4690 four-core CPU in a cramped, 2U rackmount chassis with about half an inch of clearance over the CPU cooler, not even an inch away from cheap RAM with no heatsink on a Micro ATX motherboard; in other words, a high-end CPU in a VERY unfriendly environment. Initially, I used the stock Intel cooler on the CPU, thinking that would be sufficient; hah, there's a good joke. Testing the CPU under Prime95 made it climb to 97 degrees C in under 30 seconds, at which point I pulled the plug on the test and ordered this cooler.With this cooler installed, I left Prime95 running as a reference while writing this review; it stabilized at around 89 degrees, and took about three minutes of continuous load to get there. Under normal operation (this computer runs a couple of gaming servers, Minecraft, Terraria, etc) the CPU never passes 50 degrees, and it idles at 29-32. Again, this is in an extremely cramped space with only two 80mm case fans at the far front of the unit, so you literally could not find a more hostile setup to test this thing in. In any real-world situation in a proper-sized tower, this little compact cooler would blow away the competition... I'll see myself out.As a final note, Cryorig also provides a small, sturdy product registration card with the cooler, packaged inside a pretty little foil wrapper. Don't toss it out! Register the cooler on their website instead, and they will provide you with an incredible five-year warranty. I can't express how impressed I am with Cryorig for making such an affordable product feel so premium, and the thoughtful treatment they provide with it.

For such a small cooler this is amazing, my CPU is a i5 4590 running at forced 3.5GHz and at a locked 40% fan speed my i5 never hit 60c under full load and idles at around 30c. its also pretty quiet but at 75% and higher it starts to make a bit of noise. 100% fan speed is quite loud but you should not need any higher then 50-60% speed even with an AMD FX-8xxx or Core i7 chip unless there is heavy overclocking. but if you want to overclock alot it would be better to get a bigger cooler like the Cooler Master TX3, 212 EVO or higher.Other Thoughts, if you have something like an HTPC with a low power CPU like a Celeron, Pentium G or core i3 you could the fan at a very low speed like 30-40% and have an almost silent PCFinal Thoughts, for all CPU's from i5 or FX-8xxx to Core i3's, AMD Sempron or even a Celeron this cooler is almost perfect for small PC's due to it being so small and quiet unless under heavy OC. i put a pic of the cooler itself and the temps after CPU running 100% for 3 minutes

This cooler was installed into my computer and it works well from what my knowledge is for its size. Setting it up however was not fun at all. It comes with thermal paste fortunately, but it requires you to install the fan from the back requiring you to use hex nuts not included in the box. Installing this cooler is not fun, but if you can get past that it works well.

I've obtained this fan for a couple reasons:- to go with the black/white color scheme for my build- low profile and light weight- compatible with the AM4 socket...It's 2018/2019, and I'm surprised that you either have to purchase the backplate separately or fill out a request form with proof of purchase (your cooler and your processor). AMD's Ryzen has been out for a while, and their backplate should be bundled with the cooler (or at least a rebate for the cost of it) during checkout.When you get the backplate: It's best to use a flat surface (a mat or cardboard works) and have the bottom of your motherboard face up. When installing the plate, you'll need to press down until you hear a "I'm not sure if I broke it but I don't think I did" snap. You'll know it's in when you can install the washer(s) to hold it all in place. The included instructions won't tell you that it should snap in.If you broke something else, you've pressed too hard. My condolences.With that aside (and a Type C AM4 backplate in hand), I've stressed-test my Ryzen 5 2600 (65W TDP) for 10 minutes with CPU-Z and Core Temp. Just a small test, no overclocking.- Stock Cooler: 41C Idle, 74C Stressed+ CRYORIG C7: 42-44C Idle, 68C StressedTesting results may vary on your build depending on the cores, clock speeds, amount of thermal compound/paste, length of test, heatsink material, TDP, overclocking, and/or space and air flow of your chassis.It does make for a good looking, decent performing stock cooler substitute.And, as advertised, it's got zero interference with the RAM and other crucial components.5 stars for its compact design, cooler temps under load, and its good looks.
