  Duration of ownership:3 Days

  Strengths: =Copper copper & more copper.=Original Design=Led Style-3 pin plug not working with CPU (4-Pin)

  Weaknesses: -Don't like the way it can be moved around....fixed that.-Last attachment for Intel 775 is Weak link.-Can't choose color of LED-Price is still high-Beyond Intel's MOBO weight specs

  Overall Evaluation: I finally got a chance to install my Zalman cooler on my hot new E6750. First does it cool. Excellently so far. I haven't seen how far I can push/OC this setup as its brand new to me. But more than happy with the cooling & air it pushed through the system. ----------------------------------------------------------- It marries up nicely with the Antec 900 in where its all about airflow.--I remember when this thing came out. I bought it back in 2005 X-mas & have been sitting on it since. It was stunning. Still is.--------------------------------------The heatsink surface was level and pretty smooth. I found the attachment of the backplate & stand that it is clamped to fine. But when i applies the thermal grease and began to attach the cooler to the stand. First off, its not easy with one side 1" up off of the stand, but after you get the two sides tightened down there is still a lot of play in the unit. I am used to heatsinks being much tighter or less movable. We are talking about a heat dissipation system which relies on metal to metal or Thermal compound as a conduit to exchange heat...the tighter the better. So I decided I'd use the extra (L-Type Clip and mount that over the top of the other one for a tighter fit). Hopefully there will be no consequences negatively, however the heatsink doesn't move anymore and is tighter to the CPU so that is better IMHO.-WOULD BUY THIS ONE OR 9700 AGAIN, but only with price discounts

  Strengths: Lightweight, fits my P4 3ghz socket 478, dramatic difference in CPU temps

  Weaknesses: None so far; odd that it has a manual speed control, but no biggie.

  Overall Evaluation: I was having CPU cooling issues on my P4 Prescott, so I popped off the ineffective Vantec Aeroflow 2 heatsink/fan and dropped in this large badboy - had to remove my power supply to get to the mounting screws, but it went on in 5 to 10 min altogether. Also had to tie-wrap some cables away from the fan (especially the CPU fan cable). What a difference!Note: I have not overclocked this CPU.Temps with Vantec Aeroflow 2:50C idle, topping 70C loaded (triggering monitor alert)Temps with Zalman CNPS9500LED:44C idle, only 54C loaded!And this is day 1, with new application of thermal paste (Artic Silver 5). I could not be more pleased - these temps remind me of days running my P4 2.4ghz.

  Strengths: Cooling ability, looks and it's quiet.

  Weaknesses: A bit big, so make sure it fits in your case.

  Overall Evaluation: I recently built a new machine: Pentium D 930 3.0GHz, 1GB PQI 533MHz, 250GB Maxtor SATA, XFX 6800XT 128MB, Intel D945GNTLR, Antec P180 case. I had serious problems cooling this chip down. I was running idle at around 145 degrees fahrenheit. I put this in the other night and have dropped about 30 degrees at idle. That is a remarkable difference. Also, my case has the power supply on the bottom which allows for a 120mm fan to be placed at the top of the case. I installed this fan a bit differently than suggested. I aimed the airflow straight up through the top fan. Love this thing so far. Worth every penny!!!

  Duration of ownership:

  Strengths: amazing heat dissipation, design

  Weaknesses: a little bulky

  Overall Evaluation: This cooler is outstanding. It dropped my idle and load temps on a P4 3.4ghz from 44/52 to 33/43 before the thermal paste was even cured. Can't wait to see how low it goes...

  Strengths: Easy to install. Very quiet. Dropped temps by 10c. Great Zalman website.

  Weaknesses: None yet for me. It is big but that is what helps it cool so efficiently. The only question will be the life span of the fan.

  Overall Evaluation: Used this with Artic Silver Ceramique and dropped my P4 3.06Ghz temps down from 58c on full gaming load to 47c at most. Zalman has a great website and recommend you stop there to for mobo comparison and installation video. As the ceramique sets in, the temps should drop a bit more. Great buy!

  Duration of ownership:

  Strengths: Easy installation, superb cooling

  Weaknesses: On the edge of being too heavy for the Intel specs

  Overall Evaluation: Mounted on Pentium D installed on ASUS P5N32SLI board. Easy to mount. Runs at 47C on top end; idle is about 34C. It is quiet, not quite inaudible, but almost so. Design is elegant. Auxiliary switch took some thinking to find a way to route it outside the case. I find I leave it on maximum, which is almost as quiet is minimum and 5-6C cooler.

  Strengths: The cooler was very easy to install, straight forward instructions and good illustrations. The operational aspects of the cooler are outstanding. This is one of the top coolers on the market today.

  Weaknesses: Little to none detected to this point.

  Overall Evaluation: The Zalman Ultra Quiet CPU Cooler delivers ultimate performance, minimal weight, and ulta quiet operation; all the top aspects to look for in a performance CPU cooler. Along with ease of instillation and compatibilty, this makes the CNPS9500 LED an excellent choice.

  Duration of ownership:6 Months

  Strengths: None

  Weaknesses: Everything

  Overall Evaluation: Put this in and tightened it all the way down, appeared to still be 'loose' fitting. Could never get it any better no matter what I tried. The cooling on this was no better than the copper & aluminum heatsink fan that I got with my Intel 3.0e CPU. I put a Zalman All Copper with 120 mm fan (CNPS7700-Cu)in my other 3.0e CPU computer, & the idle dropped to 28C idle, & in the 30'sC running under full load. Appears to be running cooler with Zalman Thermal paste (included) than when I tried Arctic Silver 5??? Strange.

  Strengths: Quiet, cool looking, sturdy, keeps my CPU cool! :-D

  Weaknesses: tad bit heavy, but u can look past that...voids AMD warranty...

  Overall Evaluation: I bought this cooler/fan unit when I purchased my AMD X2 4400+. I've used it from the beginning and it's never given me problems. But instead of using the cooling goop that came with the fan, I purchased Arctic Silver 5 to bond between my CPU and the heat sync. The fan also comes with the FANMATE2, but I don't use it, and my bois does a great job controlling the speed of the fan itself.-Since using this CPU, I have yet to be able to put it under a complete full load. But when running virus scanning, BOINC Seti@Home, downloading from Azureus, Firewall Software, playing F.E.A.R. at 1280x1024, and burning a DVD+R DL at the same time, speedfan has only recorded my cpu reaching up to 44*C! On average, my CPU sits around 35/36*C when idle. THIS FAN IS A MUST for a great system!-Installation wasn't too difficult. But when you have 4 drive bays, 4 hard drives, and multiple slots to use with pci and pci express; you tend to run out of room after running data and power cables everywhere, because the heat sync does take up a lot of space. I used a few twisty ties to keep some cables under control so they wouldn't lean against the heat sync or fan. Everything works great and I still have great air flow!
