Zalman CNPS7000C-ALCU 92mm 2 Ball Cooling Fan

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

I ordered this, the 7000B from Three company's now, and ALL THREE of them that were sent to me were the 7000C variant, which is not compatible with Socket 462 (the entire reason i purchased this cooler. One company refunded my money and didn't want to have it shipped back, the 2nd sent me a shipping label and its on its way back now. the 3rd has a return label but wants to make me pay for Shipping (outletPC) which i will fight them on, but i still don't have a cooler for my Socket 462 motherboard.Even tho all links were for the 7000B, i don't think these company's are looking that closely at the differences. I'm getting a bit fed up with trying to get this item. I was lery about ordering a 3rd but took the dive figuring 3rd time was a charm. Well its not. It seems every company claming to sell this at the time of review, is only looking at the picture and doesnt give a shit about what they are really selling, so long as it looks the same..Don buy this from here. Im fairly confident none of the places that are calming to sell this, are selling the correct on, but instead just trying to get more face time and get rid of units, and hoping people will be dumb enough to not know the difference.

I built myself a Core 2 Duo computer a few years ago, which means I was always stuck with the annoyingly loud stock Intel fan. Switched to this Zalman today and HOT DAMN, what a difference: the volume is noticeably lower, and the constant high-frequency pitch is totally gone. Oh, the wonders of having the ability to turn down the fan speed from 2,XXX RPM to 1,400! The larger fins also help, I'm sure.Since I also use a quiet power supply, a fanless video card, and a Solid State Drive, pretty much all I hear from my computer now is the soft, low-pitched hum of the Zalman. But it's below the threshold of bothersome.My subliminal daily rage is gone. Well worth $23.

This is an outstanding fan/heatsink.I replaced the stock intel fan with this and also upgraded my powersupply at the same time, the drop in noise has been unbelievable...the pci slot cooler I had is louder than this fan and the new PSU combined. On silent mode this thing is actually silent and yet still keeps the cpu cooler than the stock intel fan did.The one thing other reviews have noted but you can't fully appreciate 'till you get it in your hand, it's FREAKING HUGE. This is *two pounds* of copper people, you know those big cappucino mugs you see? it's definately larger than that, the pictures are misleading. You think I'm joking? buy it, you'll see! It's a monster but it's a cold *stealthy* monster.For the record, it's also looks awesome in a windowed case. If you have the room by all means do it --it's two pounds of copper!

It fit OK for me, but I bought the wrong one. I needs a fan with the 4 pin (PWM) connector, this one has 3 pins. It comes with a gizmo to manually control the speed, but who wants to do that?It sure is quiet, and cools like crazy.My motherboard has an AMD (AM3+) type socket, so all I had to do was strap it in there. So if you are a sensible person who bought a superior AMD chip, you are already one step ahead.I'm going to go ahead and find a similar item with the 4 pins and hang on to this one for another PC down the road.

Does not mention if it comes with any adapters or extra pieces to help plug into the motherboard. Hint: it doesn't. Had to send it back because the required mounting bracket was more $$ than the cooling fan itself.

This is the first item i ever gave a 1 star on amazon. This item is NOTHING like what it is claimed to be. Its incompatible with most of the listed sockets. Its cooling capabilities is also very bad when paired with some of those said processors (after modifying the cooler by replacing the clip with a compatible clip for the socket you want)DO NOT BUY please.

This cooler works great, the only problems I've had it is that it is hard to clean and the fins on the end tend to get a little bent.
