Very easy to install.
motoo
It looks nice, is nearly silent (I can't hear it on 100% speed over my other fans) and it makes my CPU stay at constant room temperature (or colder, somehow!)

Best 20 dollars I have ever spent!

After doing some research, I found this incredibly inexpensive gem that seemed to be everything I needed. My CPU was running at 110 F at idle, and well into the 150's under load. I would turn on my PC and get a "CPU FAN ERROR" and have to manually spin the fan to life for it to even start up. I knew something had to be done and fast as I am running an AMD Athlon 64 X2 5600 which heats up rather quickly as I am sure most of you know. As always, Amazon delivered the item on time, and I was eager to get started. After easily installing the Cooler Master Hyper 101A, (AMD2 socket 940) which included the paste (which by the way is just as good as any thermal paste out there,) I was very excited to bring the PC back and see what the difference was. Well here are the results. At idle before the new cooler: 110 F, now even while writing this, the temp is 86 F. That is a HUGE drop right there, but not the most impressive. Under load, the CPU would easily top 150 F without breaking a sweat. Now the temp will not exceed 110 F.(if it tries, the fan speeds up and down the temp goes) This is with the single fan set up, not dual. If you are looking for an inexpensive way to keep that cpu cool, I definitely recommend this product. It is compact in size, but huge in performance. Again, the thermal paste that comes with the unit, is as good as any. Don't waste your money on a tube of paste that says it is better, but in reality isn't.

Pros: PRICE!! Easy to install, compact, quieter than the original 120 dollar cooler.

Cons: None.

Highly recommend!!

NOTE: Three months and still cooling like a champ. Best 20 dollars I have ever spent!

The title says it all. It's not too big, not too small, and fits most cases. I have great respect for all the Cooler Master products! I also own a Cooler Master V8, which is as big as a house.

Bought this to replace the stock heatsink and cooler that were super loud and driving me crazy. Despite the complete lack of instructions this gem fit my AM3+ board like a glove, runs in complete silence when pushed to its limits and never lets my CPU get above 48-50C at max capacity.

Love this product. Highly recommend it.

I was a little skeptical about how well this would work based on reviews, however for my application this cooler works beyond my expectations lowering my CPU temp by an average of 20C under all conditions. I have an AMD Athlon 64 X2 Dual-Core 5600+ 2.8 GHz Processor, and when streaming Video it would reach 52-54C, since I install the Cooler Master Hyper 101A it will barley reach 32C under a full load, under normal use runs around 24C and believe it on not it will often idles below room temp. Not only is this a better cooler it also manages the air flow better in my case allowing me to direct the air flow from the CPU to the rear exhaust fan. This combination of air flow and cooling works Great. Additionally I have two case fans one blowing in and one out with the Cooler Master in between. Only minor complaint is the fan is a little louder that I hoped for, but part of that is because my cheep A_ _ Dell motherboard will not support variable fan speeds.

This is my first cpu cooler purchase so nothing to compare it to but it keeps my athlonII x4 930 at around 29C idle and 35C under basic use.Install was a breeze and it even came with a decent amount of thermal paste.

Quieter than the stock AMD cooler and drops the temps about 5 degrees as well. But not as quiet as I had hoped (I'm kind of picky on that).

This CPU cooling fan assembly is awesome. Had bought a barebones system with cheap cpu cooling fan which was so noisy I could hear it in my bedroom. Replaced that one with this item and it is a world of difference. Not only it is super quiet, it keeps my CPU at least 3-4C degrees cooler than the old one. Very easy to install. The instruction could be a little better but the it is written in china after all. I would recommend this item to anyone.

I bought this fan to replace the stock AMD fan in a Silverstone HTPC case. Because this rig sets in a closed Audio cabinet, the stock fan couldn't handle the heat and would be screaming after about 10 min. Needless to say, this really sucked watching a movie at low volume.

Step in this baby! I needed something that didn't involve me modding the stock AMD fan bracket or removing the motherboard. Installation was a breeze and it cools very efficiently, and I can barely hear the thing now!

Very happy with this purchase. I was able swap this out in about 10 minutes.

I do have to warn potential buyers though that this thing is pretty tall. Luckily, because I bought a pretty hefty full ATX form factor case, this was able to clear the top cover, but a smaller case would've generated problems.

As with everything PC related, check your dimensions before purchasing!
