Once I did that, and got it set up, well, this thing is GREAT!
I'm not overclocking my A10-7850, but I'm running PRIME95 (CPU) and Folding@Home (GPU), and it's almost completely silent, even running the PRIME95 torture test!
You can hear it if you put your ear right next to the computer case, but really what's the point of that?
Speaking of cases, it's about the absolute max height that will fit in mine (Silverstone RVZ02B), so I needed to fiddle with it a bit so the fan wouldn't rub on the case wall. Silverstone lists a 58mm max height for the CPU cooler, and this cooler is 60mm, so it's snug but it does work.
So long story short: if it fits your motherboard and case, it's fantastic. Quiet, easy to mount, cools very well, compact, looks pretty, and the price is right.
If it doesn't fit, (probably the motherboard; if it fits the RVZ02B, it should fit about anything) it can be made to work but it may be a bit of a chore.
Would I buy it again? Yup. And I will, next time I build a PC.
The only thing to note, unless your RAM is well outside its radius, you need to use VLP (Very Low Profile) DDR. The downward blowing fan also does a great job of cooling those pesky VRM MOSFETs and the nearby memory.
Installation is pretty easy, and best done when the motherboard is out of the case. If your case has a large enough opening that all four of the original back plate holes are exposed, you might get away with doing it in the case. Use a skinny #1 screwdriver to angle in and tighten the screws (another reason it's easier out of the case) and it only takes a couple minutes. Save your original mounting plate/hardware in case you ever want to sell the motherboard off; you're going to want to keep this beauty of a heat sink for years.
The fan seems screwed in from the bottom with two screws and is on there solid. Despite looking copper, the fins are aluminum. This should help a lot with cost and weight. The base/heat pipes are copper, which is where it really counts. The mounting brackets screw on the bottom, pending Intel or AMD. The surface was pretty rough on the bottom of mine with plenty of pits and could definitely using lapping for those looking for perfection, but I installed it despite to see where it sat in performance.
The install was somewhat easy, but I've also done a lot of cooler swaps with custom hardware in the past. The stock motherboard mounting system had to come off, then install their custom plate. One thing about the plate is it didn't feel very balanced against the back of the board. For my AMD setup, the instructions required 4 nuts with 4 plastic snap-in ends to retain them. It also called for a plastic center piece that I believe is causing the feel of lacking balance, as it seems a bit too tall. It didn't hit any of the components under the CPU, so I give them that. The back plate also doesn't hold to the mother board on it's own and seems to require the heatsink installed to keep in place, which is another downside to it. The CPU screws were a little awkward to put in, as the size of the heatsink makes you come at the screw head at an angle. Do not try to put the screw in at an angle or you will cross thread and cause issues! Make sure the screws go in straight, but the screw drive itself will be forced at an angle to install. After everything is tightened up, you can then put the motherboard in. I didn't use the paste that came with it (instead, I used AS Ceramique 2)
Cooling wise, it works awesome. I have my motherboard setting the fan at the lowest possible settings and it has yet to get much over 45*C with my setup. At that fan setting, it's nearly inaudible. If you have the fan in your hand and manually spin it, it makes no noise, yet you can feel a bit of air being pushed through the fins. I'd say this design is solid for quiet cooling.
One thing to note is this is a tight fit. With my motherboard, using standard height DDR2 ram with heat shields, it would not fit. The orientation of the heatsink was perfectly against the ram. After forcing off a the heat shield on one side of the ram stick it was hitting, I was able to get everything to fit, though the heat pipe is touching and perhaps putting a touch of pressure on the PCB of the ram stick itself. This didn't cause any issues, but it is something to note. My board supports DDR3 as well, which is a single slot over and would probably solve this issue (as long as the ram doesn't have tall heatsinks on it).
All together, if you are building a silent, slim, HTPC like I was, this thing isn't going to be beat by any other air cooler at this time, especially when considering the cost. However, overclockers may feel the need to modify this heatsink for maximum cooling and the average user may have issues with fitment into their setup.
The good: This is much quieter than a stock CPU cooler and does an excellent job of cooling.
Short form factor. (Only matters if you need it, probably if you're doing a mini-ITX build in a tiny case.)
Price is pretty good compared to other simarly sized options.
The bad: Too wide. Due to the location of the components on my mini-ITX motherboard, the edge of the cooler pushes pretty hard on the side of one of my RAM sticks to the point I was worried it might break it. Luckily it didn't. It also was touching my old graphics card, which didn't have a backplate. When I later installed a new graphics card, with a backplate that a few millimeters to the side that faces the cpu, I had to force the graphics card in, slightly bending it around the cooler, again lucky not to break the graphics card.
Also, the cooler is difficult to install because you have to angle your screw driver under the fins to get to the screws.
And as other reviews have stated, the heatsink is a pain to install. It's easily one of the worst heatsink installs I've ever dealt with. When installing, getting the screwholes to stay lined up while also applying pressure and trying to screw it together is a test in patience. It's not worth going through the hassle of installing this when it still produces an obnoxious noise when it's labeled as a "quiet" heatsink. I'm not sure if the fan quality worsened since the other reviews were posted, but I don't see anything quiet about it. If you're looking for a heatsink that makes minimal noise in a quiet room, this isn't it.
