ZALMAN CNPS7700-CU 120mm 2 Ball Cooling Fan

  • 1000 - 2000 ±10% RPM
  • Copper
ICON Loading...

Zalman bills itself as the "quiet cooling solution" and they have a reputation for easy to use, reliable products. They also have a reputation for creating products that look as good as they run. With the CNPS 7700 Cu, "bigger is better." A quiet, downward blowing 120mm ball bearing fan sits at the heart of a radial array of copper convection fins.

While it works silently in its normal setting, its Silent Mode virtually eliminates all noise as well as vibration as it cools not only the CPU, but the RAM, VGA card, Northbridge and other components. The included FAN MATE controller lets you choose in which mode the fan operates.

Heat is drawn away from the CPU by the pure copper base of the heatsink and it is transferred up into the twin semi-circular arrays of copper fins for dissipation. Both Intel Socket 775 and 478 Pentium 4 chips are supported by the 7700-Cu. It is also compatible with AMD 64 processors using 754, 939 and 940 sockets.

  • newegg Excellent Cooling Performance The ZALMAN CNPS7700-CU features a pure copper base and high-density fins, plus a powerful 120mm dual-ball bearing fan to deliver supreme cooling performance.
  • newegg Adjustable Fan Speed The ZALMAN CNPS7700-CU comes with a fan speed controller (Fan Mate 2) so you can fine tune the fan speeds for the optimum balance between cooling performance and noise level.
  • newegg Universal Socket Compatibility The ZALMAN CNPS7700-CU features broad compatibility with AMD socket 754, 939 and 940 platforms, as well as Intel socket 478 and LGA 775 platforms.

4 out of 5 eggsstill works well

Pros: At the time of this post I've been using this cooler for almost 5 years. The fan still works great and is quiet. I think this heat sink will out last the board at this rate. right now the CPU temp is fluctuating between 40 and 58C (~25C in the room) AC seems to drop the temp when its running. I've not had a thermal shutdown but the highest it get in my house is ~86F or 30 C.

Cons: heavy.. wide, and its over 2 lbs.. there are many heat pipe style coolers that are just as efficient (or more) but take up less space and weigh less. I'm still happy with my purchase.

Other Thoughts: I've been running the same 3.6Ghz Prescott P4 (TDP of ~115W) for all this time.

5 out of 5 eggsBest CPU Fan

Pros: very quiet, does good job keeping the temperature low on Socket 478 P4 Prescott

Cons: it's not free

Other Thoughts: This is the second CPU fan I buy (similar model). I am still using the one I bought few years ago. Still works flawlessly. Make sure you check if this monster will fit into the case. Most modern cases are big enough though, except these all-in-one solutions. be careful with the fins. They are pretty sharp.
Newegg's delivery was turbo-fast as usual. I paid regular postage, as usual, I got it in 2 days, as usual :)

5 out of 5 eggsGreat Big Cooler

Pros: Durable: I've owned this cooler for four years. Not a whimper from the bearings. High thermal capacity: Much more than comparable weight aluminum coolers. Low noise: Easily the quietest component in my system. 7200 RPM HDs make far more noise than the fan. Comes with a rheostat if you find it necessary to further quiet the fan.

Cons: Somewhat heavy: a danger when moving the case. A drop may break a mount off the motherboard. I've never had this problem however. Fins can be bent but this doesn't affect the performance of the cooler. Large computer case required due to clearance issues.

Other Thoughts: I've owned both this cooler and it's smaller 90mm brother. The 90mm is still going after SIX YEARS of constant use on a P4, Q6600, and finally an LGA775 Celeron. Adapters have always been inexpensive and available for both the 120mm and the 90mm. Currently the 120mm is on the Q6600. I found the 90mm to be inadequate after jacking up the core clock to 3.0 GHz on the Q6600 but this merely my cautious nature by no means a requirement. The 120mm can have clearance issues in computer cases with power supplies or fans mounted on the top rear of the case. If it fits the fan blows air onto the northbridge heatsink and onto the caps surrounding the processor; an added bonus. The fins can be bent and are somewhat sharp. I've never cut myself but I have bent the fins that sit closest to the mount screws. The only affect has been cosmetic in nature. The weight of the cooler comes into play while handling the machine.

2 out of 5 eggsKilled my motherboard

Pros: Looks nice and well made. The large fan blows air over the memory.

Cons: Very heavy and difficult to install on a 478 socket. The 'S' and 'L' brackets don't fit tightly putting uneven strain on the motherboard.

The huge flower design leaves little room for error.

Other Thoughts: My newly recapped and tested motherboard died. All the weight bent the board damaging the socket. It no longer posts and turns off in seconds - a total loss.

Don't use this CPU cooler with a 478 socket, it is not compatible. Zalman makes a lighter version with a 92mm fan that puts less stress on the motherboard.

5 out of 5 eggsNice case

Pros: Setup with an Intel DG45FC mobo with dual 2.5" HDs configured RAID 0 on Silverman 2.5"-to-3.5" adapter. Installed SeaSonic ECO 300 300W SFX12V PSU. Non-modular, but small and with a little work, easily managed in terms of cabling.

Cons: Taking it apart will be too much work: six screws on each side, four thumbscrews for the PSU, four for the mobo, minimal access for hands within case interior.

Other Thoughts: Mini ITX boards are small. The challenge is finding a case that is too small for a practical buildout. This case is the best compromise and is high quality.

5 out of 5 eggsGreat Cooling, But Noisier Than Expected.

Pros: Great cooling. Much better than stock Intel fan.

Cons: Unfortunately, this fan produces more noise than I was expecting. It isn't coming from the spinning of the fan, it's a noise that is generated by the way the air passes over the uppermost/outermost portions of the cooper fins. It's a turbulent roaring sound, and the fact that the fins extend so far out and are unsupported at their extremities allows the fins to vibrate, resulting in an even greater sound of turbulence.
The intensity of this sound is very noticeable when the fan is running at %100 speed. Fortunately, it cools my CPU well enough that the fan doesn't reach that speed (that is, once I properly set my BIOS fan controller).
Now that I've witnessed the acoustic flaws in this type of flat-set, wide-finned design, I think I'll start buying the vertical-mount fans from this point on. The vertical coolers, with their tightly stacked rows of fins, shouldn't suffer from these vibration/noise problems.

Other Thoughts: To install it, I had to take one of heatsink fins off of one side of a RAM module, but that's no big deal.

Case: Azza Solano 1000
MB: GIGABYTE GA-EP43-UD3L
CPU: Core2 Duo E7500
RAM: Patriot Viper II PV224G8500ELKB, DDR2 1066, 2x2GB

5 out of 5 eggs2 years still going

Pros: I only review stuff thats been good for more than 1 year.
This one fan has been on 3 different motherboard upgrades and processors fro0m an AMD Athlon 4000 to a PHENOM I 9850 over the past 3 years.

-easy to clean
-cools everything around it
-quiet
-makes good use of case airflow for maximum rpm

Cons: fins are fragile

Other Thoughts: LAP THIS AND YOUR PROCESSOR...EVEN BETTER
Able to overclock Phenom from 2.5 to 3.2 (good case cooling) with 1.43 volts and this fan keeps it at 56c under full load.

at full speed, multiple motherboards tell me this thing is running at 2600rpm full speed... with a 120mm side panel fan blowing on top of this i got 2732 full speed (i thought it was bios but every board shows this speed, so case fan positioning really help this fan much more than other fans. .... good stuff.

5 out of 5 eggsNearly Silent and very cool

Pros: Nearly Silent and very cool. I run it at 1200 RPM and keeps my AMD 9350e at 41c with an ambient room temperature of 26C. Cooled the mobo down about 3C versus the stock AMD fans. It is quality. Nice machine work. Comes with thermal paste.

Cons: 3 pin rather than 4 pin, so you have to do the work to find the perfect balance between sound and heat. Covers the 1st memory slot, although it also cools your memory.

Other Thoughts: Not really a Pro or Con, but I have a ASUS M3A78-CM mobo and to make it work I drilled two small holes in the stock heat sink bracket. Then I followed the directions. Worked like a champ, although I'm sure I negated all sorts of warranties in the process. Fit was tight but perfect.
