Pros: Moves air, dissipates heat. Does what I expected, hasn't failed.

Cons: Cannot be used as a life preserver.

Other Thoughts: For my new build I'm switching to a closed loop water cooler because gigantic air coolers just aren't cool enough anymore.

Pros: Very quiet cooler as many have said, computer runs so much cooler and quieter with this fan/heatsink than it did with the stock Intel cooler on my i7 950 processor. No complaints about the results of this product at all. Good value.

Cons: This thing can be a pain to install as many others have said. Many installed the cooler while the motherboard was outside of their case, I used a second person to hold the mount in place while securing the screws to it. The screws do round out fairly easily too, so get them tight enough to hold the cooler in place but don't tighten them so much they start to round out.

Other Thoughts: Overall, I am very happy with this product, the only reason for the markdown to 4 eggs was due to the mounting hardware issues, if better hardware was included and wasn't so much of a pain to install, I would easily have given 5 eggs.

Pros: I originally gave this a 2 stars because my fan started rattling after a year, today i opened the mail and there's a new fan, thankyou Zalman, i dont remember requesting it, maybe they read my review, so i am now well pleased, thanks again for making it right, even though i've owned it for 2 years now.

Cons: None.

Other Thoughts: Im a liquid cooler and nothings beats a waterblock., but untill my money gets better, its air for now.

Pros: Everything... except it's a blue LED (my case is black/green theme.. so it'll have to go soon here but, good for now)

As with every other zalman cooler i've purchased it installed perfectly, no issues (well.. some but they were the MBs fault, not the coolers) and it keeps my shiney new i5-6600k under 60C (after a 24 hour stress it still hadn't broke 60). No overclock yet but i'm sure it'll keep it under 70 when I start to push the voltage a wee bit..

Oh and as always, it's quiet..

Cons: Nothing.. again except it's a blue LED but.. I knew this going in and just didn't have the money to spend on the AIO water setup I want yet..

Other Thoughts: System Specs
Intel i5-6600k
ASUS ROG Maximus VIII z170 MB
G.SKILL DDR4-2400 2x8GB RAM
Corsair RM750i 750w PSU
MSI GTX 970 100ME
Zalman CNPS9900 cooler
Samsung EVO 850 250gb SSD

Pros: This cooler looks sharp and does the job well.

Cons: It's sharp in other ways too. Once the plastic fin cover comes off, it can cut you up. So, you have to be careful. Leave it on during installation. With the new mounting system, it is a little easier to install. I did have to put the cooler brackets in a vice to bend them a little to make them easier to screw down. This cooler has to be installed before putting the motherboard in the case.

Other Thoughts: Good contact with the CPU is necessary, but I think Zalman wants to weld the cooler to the CPU.

Pros: Quiet ,best non water cooler.

Cons: Installation can be tough.

Pros: if you have to put on am3 + dont it is to hard on your mobo you have to put to mush focse on your mobo to put it on

Cons: if you have to put on am3 + dont it is to hard on your mobo you have to put to mush focse on your mobo to put it on

Other Thoughts: if you have to put on am3 + dont it is to hard on your mobo you have to put to mush focse on your mobo to put it on

Pros: Quiet and cool. After doing a bunch of research Zalman seemed to be the way to go. They have earned a lifetime customers from me.

Cons: None

Pros: Unique design, blue LED fan, all copper heat pipes and fins, noticed a reduction in CPU temperatures over stock cooler by an average of 17 Degrees Celsius (at normal loads) even when overclocking the CPU.

Cons: Can be difficult to install. If possible, install this CPU cooler Before installing the motherboard into your case. Since my motherboard and other hardware was already installed, it was rather difficult to install, and like many others, I had a great deal of cuts on my hand with blood, nothing serious, but can be painful. Trying to screw in the bolts to attach to your motherboard is difficult, as you have a hex key -type tool and have to use an odd angle to screw in the bolts, thus causing cuts on your hands.

Other Thoughts: This is a great CPU cooler and does it's job well at cooling the CPU. I recommend this cooler to anyone who does not prefer liquid cooling, just try to install the CPU cooler BEFORE installing your Motherboard and other hardware if possible. I also can confirm that this CPU cooler DOES work with Socket LGA 1150. Minus 1 egg for difficult installation, would be nice if it was a push-pin install rather than the odd angle you have to screw in the bolts to your motherboard, otherwise this would be 5 eggs.

Pros: have had it for a year and only just recently it made a skitter sound and the fan stopped spinning and i had to restart my pc to get it going again. (only happened once)

keeps my AMD FX-6300 at 9c idle 44c max when at 100%.

Cons: Must be installed with mother board out of the case.

very heavy moving your system could undo or break a good thermal compound bond.

Had to remove the board to install, ackward hex screws directly under the main body of the cooler.

fan is not replaceable or this thing could be a lifetime cooler.
