Quiet at moderate speed
Pros: Quiet/inaudible (depending on speed) Moderately priced 5 year warranty
Cons: I installed two of these as intake fans in an Antec Solo case. The included rubber grommets are too big to fit behind the intake air filter, so I attached the fans with machine screws (not included). No installation manual in the box or on the manufacturer's web site. The FAQ on the web site shows how to install the rubber grommets.
Overall Review: These fans have a four pin connector which allows the motherboard to control the fan speed. If you plug these into a three pin connector, the fans will run at maximum speed, which is specified to be 2000 RPM but is actually about 2120 RPM. At that speed, the fans move a lot of air but are moderately noisy. The noise is is fairly tonal. If you connect them to a four pin connector on your motherboard, then the speed will depend on your motherboard. My motherboard runs these at 1300 to 1350 RPM, and I can't hear them at all. If your motherboard doesn't have the ability to control fan speed, you may want one of the other variants of this fan (N82E16835426004 or N82E16835426006).
Only for heat sinks with limited contact area
Pros: Reduced the temperature of my Phenom II X3 710 processor by about 2 degrees under load.
Cons: I tried using this with the stock cooler on an AMD Phenom II X6 processor, which has a flat base covering the entire top of the processor. When I removed this cooler, it yanked the processor right out of the socket. The only way I was able to get the processor off of the heat sink was to slide the processor sideways. When I grabbed the edges of the processor and pulled away from the heat sink, it wouldn't budge. Given the prevalence of direct touch heat pipe products, I'm not deducting any eggs for this. I am, however, deducting two eggs for shipping the product without a manual and making me discover the product's limitations the hard way.
Pros: Board has functioned flawlessly since I purchased it 10 months ago. Has some support for overclocking (but see cons).
Cons: Overclocking the CPU multiplier results in a fixed CPU voltage, regardless of CPU frequency. EIST still functions in the sense that it can reduce the CPU frequency under light load, but that doesn't save any power because the CPU voltage no longer drops when the frequency drops. The board does not have an option to overclock the processor memory controller. Asus does not bother to document the motherboard sensors. It has a Nuvoton NCT 6791D chip, which can be read using the Linux nct6775 kernel module, and will give you fan speeds and various voltages, leaving it up to you to guess which is which. The oscillator on the board I purchased is slightly slow, resulting in a 3.5 Ghz processor running at 3.49190 Ghz. Obviously the performance loss is trivial.
Overall Review: The marketing emphasis with this board is on reliability. The Asus B85M-E/CSM motherboard has almost the same features, but I decided to spend a few more bucks for the Vangaurd B85, and I'm happy with the result.
Pros: Works (on a SATA II drive). The cable is 4-5/8 inches long if you don't include the length of the connectors. The right angle connector causes the cable to point downwards (assuming that the drive is right side up). I used this cable to connect a hard drive that was about 2 inches higher than the SATA connector on my motherboard.
Overall Review: As of this writing, shipping on Coboc brand cables is $2 for one cable and $3 for two or more cables, so it makes sense to order a bunch of them at once. They don't all have to be the same type.
Made by Seasonic
Pros: I don't own this product, but another reviewer suggested that Corsair is better than Seasonic so I decided to post a review to let people know that this power supply is manufactured by Seasonic. That's a pro because Seasonic builds quality products.
Cons: The other reviewer reported getting several DOA Seasonic power supplies; obviously the same thing could happen with the 520HX since the manufacturer is the same. But I doubt that Seasonic ships very many DOA power supplies; the reviewer probably just had a run of bad luck.
Overall Review: When choosing between this power supply and ones sold by Seasonic under its own name, I'd ignore the name of the box and make my decision based on features and price.
