The current range of Intel and AMD processors generate potentially damaging heat – especially during high intensity processing. The smaller cases restrict air flow leading to increased potential for unstable computing. Zalman's CNPS 8700 delivers a cooling solution designed to fit into Slim Tower and low-profile Home Theater PC enclosures.
A 110mm spins at 2100 RPM between two semi-circular arrays of copper convection fins. These fins are supported by a pair of copper heat pipes which circle around the fan delivering thermal transference performance equal to a four-pipe array. Zalman's quality workmanship is apparent from the mirror finish of the copper base to the twin copper heatpipes that bend around the cooler.
Pulse Width Modulation, or PWM, allows the computer's BIOS to automatically adjust the fan's speed according to the thermal need of the system as it blows air over the ultra-thin .2mm fins. With its unrestricted airflow, it is able to cool the RAM, VGA card, Northbridge and other nearby components in addition to the CPU. Its Supporting the entire current range of AMD AM2, 754, 939 and 940 processors along with the Intel 775 chips, the CNPS 8700 allows you to protect your investment and to ensure its continued reliability.

Great cooler provided enough space
- Pros: Looks great, it's a Zalman, they make the best after market coolers and have been for years.
- Cons: Quite large. Yow...see other thoughts. Still hate the Zalman mounting bracket and system...please Mr. Zalman, come up with a more "stock cooler" fan mounting system and save us all hours of frustration and plenty of smeared thermal paste.
- Other Thoughts: So...if you are planning on buying ASUS's new motherboard, the P5K3 Deluxe, which many people at this point should want to because it's the only board to utilize DDR3 RAM at this point, and you want this CPU fan...JOG ON! The heatsinks on the mobo prevent you from fitting the mounting bracket(s) on. Completly incompatable with this board...somewhat of an anomoly, cause I'm pretty sure it's only with this board. I have to send the damned fan back and find one that mounts more traditionally. So, Bottom Line:
DON'T BUY THIS FOR YOUR ASUS P5K3 DELUXE MOBO, IT WILL NOT FIT! Otherwise though, I'm sure this thing kicks some serious but.
Excellent in my SFF case
- Pros: Fit in my SFF Q-Pack2 case without a problem on my Asus P5K-VM G33 Motherboard. Was able to overclock a Q6600 from 2.4 to 3.0GHz on its low fan setting. Absolutely silent up to low-medium speed. By blowing air in all directions it cools the north bridge heatsink and surrounding motherboard components as well.
- Cons: Doesn't have a 4 pin connection that would allow its speed to be automatically controlled by the motherboard.
- Other Thoughts: I used the included FanMate controller to make it silent, but would have preferred to let the motherboard control it with PWM (which is common on all recent Intel boards).

not impressed
- Pros: Looks cool.
- Cons: Temps stayed the same as stock heat pipe cooler that came with processor.
- Other Thoughts: My AMD quad core 955 was getting up to around 60c at about 50-60% load on the stock cooler which I thought was way too hot. So, I bought this thinking it would take the temps down at least 5c. No such luck, opened the system up and optimized cabling to help airflow. Bunch of zip strips later I managed to cool it by another couple degrees celsius. The case is a micro atx case but it's got an aftermarket 120mm fan with speed control (maxed) to get fresh air into the system and it is moving a LOT of air. CPU fan just isn't making a difference though. Bummer.
Good for a mild OC
- Pros: Sufficient for a 3.89 OC on my Q9650. Temps got a little high for my liking during Prime95 runs and VMware folding so I dropped it down to 3.60 when I ran my cpu at full load. With 6 120 x 120 x 25 mm case fans and a 230 x 200 x ?? mm case fan, my max load (after 12 hours of Prime95) temps @3.60 were 75, 73, 72, 69 as reported by RealTemp. The average core temps were all about 2-3C cooler. Not bad for a HSF at this price point. If you have less case fans, then expect your temps to be a little higher.
- Cons: Installation. If you are putting this on a Gig UD3P it will fit, but the instructions will be useless since there isn't enough clearance around socket for the clip. I had to bend the clip a little and hook it onto the mounting bracket and then hold it there while I wrestled with the HS. But it does fit and patience is most certainly a virtue.
- Other Thoughts: A constant frustration I have with reviews on cpu coolers is (and this goes for all coolers, not just this one specifically) is that when most people give their temps, they do not specify if it is a core temp or a socket temp. When I hear someone say that their cpu temp dropped to '55C', for example, and notice that they are running a quad core, I have to wonder what temp they are referring to. This is important since core temps (in my experience) tend to run at least 10C - 15C hotter than socket temp and both can be considered a cpu temp. So, with a socket temp of 55C, core temps are probably running at at least 70C (this will, of course, vary from one machine to the next and from one cpu core to another).

- Pros: Follow-up
- Cons: Follow-up
- Other Thoughts: To the previous post, you cannot control this fan with the bios, it needs to have a 4 wire setup not three...
