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.

One key warning...
- Pros: Quiet, cool
- Cons: Heavy, awkward, won't fit in all tower cases, low bang for buck. (There are equally good coolers that are much less expensive.)
If you get one, **be SURE** to attach a warning label on the outside of your case to remind yourself to remove or secure this fan before moving or shipping the PC. Zalman's instructions do warn you about this, but like me, you may forget the PC you build with it has this fan a year later. If the case gets bumped moderately hard the fan can easily break away (because of its mass) and take the CPU with it, and if it rattles around loose inside the PC case in shipping, it will destroy other key components like your mobo and video card. The damage can occur with only a moderate bump-- one that a typical PC and fan would survive just fine can destroy this one. So be very careful with it. There are less kludgy but still effective solutions than this one which requires special handling in moving (LAN party?) or shipping the PC. I would not get another one.
- Other Thoughts: It's actually a decent and quiet cooler. In that sense, my one-star rating is admittedly very unfair. I gave it that rating only so anybody sorting to show lowest ratings first will pop this review and see the warning and problem which nobody else is commenting on. There are so many 5-star ratings on this product that my 1-star rating is not going to have any significant affect on its average rating. Still, I recommend a different solution because of the cost and the special handling required for any PC that has this fan.
Dust Magnet
- Pros: Adequate cooling. I find it’s rather attractive. It’s worked three years without any mechanical failure.
- Cons: I’ve owned this product for three years. Until recently, it was used daily in my now aging P4. I replaced it with a heat pipe type cooler. The reason I did this was due to the way that it collects dust. I live in a relatively spotless house. 4 years USMC, it’s clean! I live alone, no pets, and I don’t smoke. With that being said, this product had to be frequently cleaned. If it was left unchecked for five or six weeks, the fins would clog, and the processor temperature would rise. The three-pin connector won’t work properly on Intel 4 pin boards, most new boards. If you’re into quiet computers, you’re going to notice an audible whine at low rpm, “silent mode.” I found it rather annoying. You have to take the entire computer apart to mount it. If it’s a new build, it’s no big deal. I would suggest a heat pipe cooler that fits your board without modifications or a lot of assembly. Look around this site, you’ll find one.
- Other Thoughts: I bought this because of how it looked. I had one of those, “looked cool, gotta have it,” moments. I wish that I had purchased one of the heat pipe coolers instead. The heat pipes work much better, operate more quietly, and today you can get them to fit your board just like a stock cooler. It is rather heavy unlike the new heat pipe coolers. On the date of my review, 5th of November 2007, this product costs twice as much as the heat pipe coolers.
I hope that my review was helpful to you. bolillo_loco

Nearly 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.
Check your measurments
- Pros: It's a big beautiful fan that probably works great.
- Cons: This is fan is huge.
I have a normal sized motherboard and it *would not fit* on it with my graphics card and RAM attached.
Before you purchase this baby get into your case and do the measurements.
- Other Thoughts: It's also rather heavy which may or may not cause you problems if you ever move your tower.
Hasn't let me down for 4 years running...
- Pros: BIG and made of copper. Lots of surface area and its downward orientation relative to the motherboard means that it cools surrounding components (NB and PWMs especially) as well. Since copper is better at conducting heat than aluminum, this one is ideal for unusually hot CPUs. Pair it with an intake fan on your side panel to feed it fresh outside air, and this puppy will work wonders.
- Cons: BIG and made of copper. As numerous folks have pointed out, this cooler can be unwieldy and especially difficult to place if your board has tall heatsinks. With regards to the copper, while better than aluminum at conducting heat, it's also much heavier. There's no point in restating everyone else's comments on being cautious with moving your system other than to say that they're 100% correct (at least the non-hyperbolous ones).
- Other Thoughts: Over the years, I've had this cooling a Pentium D 840, a Pentium D 940, and a Core2 Duo E6420, all of which were overclocked. It's still on the E6420 to this day, keeping it at roughly 50 C on full load with a 1Ghz overclock (3.2 up from stock 2.13). While the weight can be an issue, I have to say that I've yet to see this thing break any of the boards on which it's been installed.
That being said, it can be a bit tricky to reinstall due to the fin structure: the fins are cut slightly into the contact surface, so when cleaning off old thermal compound, you need to be careful so as not to allow any solvent to leak into the fin cuts. After cleaning, sit it upright to let any stray solvent drip out before reapplying, otherwise it may end up leaking onto your CPU and, at the very least, wreaking havoc on the newly-applied compound.
Other than that, this is the oldest part of my computer and has served me better than anything.
