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!

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.

Since Cooler Master likes to put this all together, I'll mention that this is for the Cooler Master Hyper 101a - CPU Cooler with 2 yada yada - the AMD edition. I bought this because the stock AMD cooler on my AMD FX-8320 is loud and obnoxious and I think part of the fan was broken because it was making a weird grinding/clicking noise. Kind of like when you accidentally suck up a rock with a vacuum cleaner.

Anyway, pros and cons.
Pros
1. My CPU idled at 40C and was about 60C under load. With this cooler, it's now between 34-36C under load and I haven't gotten it above 50C under load yet (tested by playing games and rendering a video...simultaneously. I'm sure I could top that using Prime95 or something but I'm lazy). So the cooling difference is noticeable when idling and much more substantial when under load.
2. Fairly easy to install once you sit down and look at it. It took a minute because it didn't really click but once it did I was able to install it in just a few minutes. It does NOT require the removal of your motherboard.
3. Much, much quieter than the stock AMD fan. Much quieter. And cooler. And more efficient. Yay!
4. This fan fit inside of my Cooler Master HAF 912 case without any problems and with about 3-4 inches to spare. In other words, this thing has a small footprint.
5. You can decide to have the fan blow toward the back of your computer or toward the front (toward your DVD drive and RAM). I chose to have it pointed toward the back of the PC because then it blows right into an exhaust fan which helps remove the hot air more quickly. Also, who points their CPU fan at their RAM?
6. It was cheap. Under $20 is a good deal for a CPU cooler that outperforms the stock CPU cooler.

I installed this AMD version of Cooler Master's smallest heatsink, the 101 (Amazon: Why do you group all reviews for FIVE different models on the same page?? !!!), to cool my slightly overclocked, 65 watt dual core CPU.

I did replace the included fan with twin 80 mm PWM fans from Noctua (not saying anything derogatory about CM's fan; I had the Noctua's anyway...), and I also used Noctua's thermal paste, being sure to apply a small amount of extra paste in the narrow grooves where the copper heatpipes meet the base, and the recommended 'pea-sized' dollop in the center of the CPU cover.

Installation was straightforward and nearly self explanatory; the included instructions seemed unnecessary and rather confusing, with miniature text. Because it weighs so little even w/ two fans, no backplate is necessary for my AMD motherboard. Hardware is included for a second fan. I much prefer Cooler Master's screw-mounted plastic brackets to the paper clip type wire method of fan attachment. The location of the motherboard locking lever for this AMD version does prevent the second fan from sitting all the way down on the radiator, but because it's already so compact, this didn't cause any clearance problems with my case's side panel.

My rig is a micro-ATX motherboard in a very compact, narrow 'mini tower', so there isn't a whole lot of extra space for a tall or wide heatsink. In a 70 degree Fahrenheit home office, my CPU has yet to surpass 45 Celsius (according to Speedfan); even while performing AVG diagnostic scan set to 'FAST' with nearly two minutes of continuous 100% CPU usage, or with a half dozen tabs running while simultaneously performing dozens of Windoze7 updates and watching HD video from NY Times' website.

AMD should start including this cooler with their CPU's up to 95 watts. It's superior to their stock setup. This is a great deal for under twenty bucks !
