This is very big. It will be like a big wheel that will take up about a quarter of the size of your motherboard (mobo) with your central processing unit (cpu; processor) at its centre. It looks small in the picture but the unit is 136mm in diameter (5.35") and probably the biggest component in your computer next to the mobo and power supply unit (psu). To top it off it requires a full dismantling of the system to install because of a back support plate that goes onto the rear of the mobo. The fan inside the spreading metal heatsink is 120mm fan that can run at around 2000 RPM max creating 32 dB but there is a controller with the unit, called a Fan Mate 2, that allows you to control the speed of the fan and so decrease the noise. Apart from its enormous size the unit weighs in at a whopping 1000g which is over 2 lbs. Given that the cooler is so big they have gone to great lengths to create a very harsh to install support frame that will test a novice who may want to consider getting a professional to install it unless you are happy taking out your mobo. You should also double check that this Zalman heatsink supports your mobo as they have dropped support for certain types of mobos. So check before you buy. Installing the actual heatsink is not such a big deal as the parts are very well designed but it does require that you have front and back access to your mobo. You may also find this to be a bit of a squeeze with your PSU unit so again maybe doing some measurements before you buy is a good idea. I found zero clearance between my PSU and the cooler. It literally just breezed against it. The unit is a silent solution not an overclocking solution even though it can be used with overclocking. For those looking to create a cooler, less noisy computer, the Zalman will replace that noisy generic heatsink with a silent one. Your system will also be a little cooler, but not a whole pile, and in some cases there will be no discernable drop in temperature. It is the quietest air-based CPU cooler on the market. That is what is was designed for and that is exactly what it does. If you can't sleep because your computer sounds loud then this will probably help you get some extra forty winks. You may have to disable the generic case fan to hear the silence and of course hard drive activity will play a part in noise, but as for getting rid of a major noise culprit - the generic heatsink, this Zalman is the best around. Just get it, install it, or find someone who can. It is worth it.

I have a Pentium 4 3.0GHZ 800FSB cpu, and while encoding video my temps were reaching a CrItIcAl 89 Celcius!!! This was with the boxed heatsink/fan. How Intel provides a heatsink/fan combo that doesn't even meet their own thermal spec is beyond me.

Anyway, how does 50 Celcius sound, under full load? And in silent mode, no less! Forget the CPU fan noise that drowned out everything in the room, now I can actually concentrate.

39 degrees Celcius for $35.99??? I never expected this much of an upgrade from a heatsink/combo swap.

Make sure you check your clearances though, because this guy is a monster.

Because my PC was making too much noise which I could hear even from next room, I went and upgraded my Power supply and CPU Fan with "Zalman 400W Noiseless Power SupplyZM400AAPF" and "Zalman CNPS7000B-AlCu" CPU Fan.

- After I replaced the Power supply the noise went down a bit but I could still hear the PC in the room.

- When I replaced the CPU Fan the system become so quiet that initially I wasn't sure if I had powered the system at all.

- I have ATX Mid-Tower and now I'm not even sure if the system is working at all if I don't see the Power LED.

- I have Pentium 4 with "Socket 775 CPU" and the only small drawback was that I had to purchase and install additional bracket (ZM-CS1). The bracket didn't fit the motherboard opening (ECS 848P-A7) so I end up attaching the bracket with only 3 screws instead of 4. Be aware that because the screws for the bracket are installed around the processor from the bottom side of the motherboard you have to take out all cards and disconnect all other components (HD/CD/DVD/..) first.

- 2-nd small issue was that the bracket 2 screw holes didn't match well the FAN screw opening and I had to play a while until I was able to put the 2 screws

- after this small installation difficulties my Desktop PC is now MORE SILENT than my Dell Laptop.

-> Definitely Silent Solution which I highly recommend

Fan runs at a lower rpm than my original fan, but I was hoping that it was a little bit more quieter than it is, but it's an definite improvement. Installation was a breeze though.

I just installed this cooler yesterday into my Antec Aria case. The Aria is a very small case and this heatsink fits in snugly. My case sits next to my monitor and i can honestly say that the fan runs as advertised. At the lowest fan speed (with the included fan speed controller) i cannot hear it. The Antec Cyclone blower in the back of my case seems to make the most noise now. The CPU temperature seems to have gone down too. With the old heatsink the temperature was around 42c but now its around 35c. Removal of my old heatsink and installation of the new Zalman into my Asrock K8NF4G-SATA2 motherboard required me to remove the motherboard from the case and remove some bits from the motherboard. Its not for inexperienced computer users so you might want your local shop to fit it. I created a page incase you have an Asrock K8NF4G-SATA2 motherboard and want to safely install this cooler on your own. Checkout: members.dodo.com.au/~robbiehook/

This was my first time changing out a heatsink/fan combo and WOW what a Difference! The reason why I wanted to swap out the stock Intel heatsink for this Zalman 7000B-Cu was obviously the temperatures I was getting from the CPU. I think someone was playing around with my heatsink/processor because the old thermal paste on it was warped and some was missing. Anyway, checked out the BIOS/PC health settings one day and surprised to find out that Idle CPU temp was 64 Celsius!!! Imagine what the full load temp would have been!

Needless to say, I was troubled and began my research on Heatsink's on the WWW. This Zalman flower kept coming up in good reviews(good cooling AND low noise), but I was hesistant because of the size. I have a Socket 478-Giga-byte SinXP1394 board with the Dual Phase Power board installed next to the processor slot which gets in the way of the huge Zalman. It was either the DPVRM board with the cool blue LED or the Zalman 7000B-Cu Heatsink with great reviews or some other less-than-satisfactory Heatsink.

Well, Zalman won! I installed that puppy in 20 minutes mostly because I got a little messy with thermal goo/cleanup. Very easy to install--just two screws did it!

Booting up gave me the surprise of the day--after reading so many good reviews of this product being low noise and lowering other peoples CPU temperatures by 5-10 degrees, I was shocked. My idle CPU temperature was now down to 35 Celsius--from 64 degrees! A 29 degree difference!! Now that was amazing.

The noise is also minimal, just as advertised. EXCELLENT PRODUCT!

Zalman has sure spoiled me now with the super-easy installation and efficiency of this product. Providing some thermal paste was great and also the ability of this heatsink to work with AMD chips was also a PLUS. The price is excellent as well...Amazon is on par with other specialty stores.

This cooler is exactly what I was looking for. It is truely quiet in Silent mode (1300rpm). My 2400+ Athlon XP hits a high of 55c in silent mode, and 47c in normal mode (2400rpm). It idles in the mid 40s. Normal mode is audible but not deafenly so. It's incredibly heavy but it has a good mounting mechanism and comes with all the parts you need.

Overall I am very happy with the zalman. I wanted a silent cooler than could keep the cpu temperatures down, and it fits the bill.

I just installed this CPU cooler this afternoon after going on line and reading a few reviews. I have a 3.4GHz Pentium 4 on a socket 478 motherboard. It had been running hot (80 C and over according to the Everest computer status monitor) now that our weather has gotten warm. I checked that I had enough clearance around the processor socket, then installed the new cooler in about ten minutes. The steps for the socket 478 installation were: remove old fan and heat sink, replace the old thermal grease, slip two clip supports into the socket frame, put the new heat sink and fan in place and tighten two bolts. Then plug the fan controller intro the motherboard and the fan motor. That was all (the other socket types looked a little more complicated). Now under stress, the CPU temperature is running 20 C lower than with the original (budget type) fan and heat sink. I was amazed at how simple the installation was.

I I recently installed this fan replacing the noisy Intel stock fan for a P4 3.6 Ghz, It keeps my CPU cool and it doesn't make a sound. It comes with everything needed to install including thermal paste and was very easy to install. i recommended it for P4 and AMD compatible.. really is this Zalman is much, much quieter.

With the included fan speed control I turned down the speed slightly and it is "silent"!!! I love it. It's big and fairly heavy but, it works and cools great!
