Pros: I have 6 of these on a RX360 radiator and they're quiet! Even at max RPM(1600 according to my mobo, PWM controlled) they were barely louder than my water pump rated at <25dBA. They work OK on voltage control. I didn't notice any increased noise. Overall, it's a nice PWM fan. Very good for low resistance applications. Acceptable performance in push/pull on radiators. Note: the rest of this review is largely radiator and negative resistance specific.

Cons: Cost. I got mine for $9/ea off newegg on sale, but more than that and these start to become pretty expensive considering I'm running 6 of them. It all depends on how much of an issue noise is to you. There may be other fans out there that perform better with less noise, but I did A LOT of looking and didn't see anything better other than the Gentle Typhoons which are discontinued. General negative, not limited to these fans: specs can be deceptive. I would recommend not buying any fan solely based off of the MFR listed specs as most are generally tested in an open space without negative pressure or resistance to airflow as you will experience in most real world applications. That's where the static pressure rating of the fan would come in if it were accurate, but from what I've seen from other people's test results these are not the most powerful fan out there. I wouldn't use these for a radiator unless you're really looking for something quiet and then I would also only run them in push/pull with gasket material as these are not a perfectly square shape. Running gasket on a radiator will also help space the fan away from the rad which is a good thing because it will allow air to flow through the fins more evenly and theoretically reduce how much the fan motor needs to work to get the air to flow.

Overall Review: I own various cooler master fans(the cougars are better than all of them) and a 140mm noctua which is really nice if not a bit loud. In my experience the best fan that I've come across in terms of noise/static pressure/cost ratio is the 1650RPM fan made by XSPC. I got them with my 360mm radiator and they are available separately. The reason I'm not running these on my radiator is because XSPC doesn't make PWM fans and my Gigabyte Z87X motherboard doesn't support voltage regulation as a fan control option. They're louder than the cougars but the performance is that much more as well. Tip: there are forums and websites out there where people have taken it upon themselves to do comparative spec reviews of multiple fans measuring dBA and cooling performance. Check out Martins.

Pros: Edit: Heavily revised review. This card would be pretty sweet if it worked like it should. What should make this card stand out? Comes with an M.2 slot, integrated Creative sound card, easy access MB controls such as reset and power, Killer Ethernet(which is supposed to improve in game experience), and also red LED lighting which looks pretty nice.

Cons: The Killer NIC is a piece of junk. Unfortunately, I realized this too late. Tried dozens of drivers, etc. Tried straight drivers, tried Killer's program, tried the removal tool and tried the stuff on forums. It initially disconnected every 15min when I was doing heavy downloading, very annoying but I thought I worked around it with the 8th driver config I tried. After 3 weeks of use it started rapidly connecting/disconnecting, and somehow slowed the internet connection speed on the entire network from 60mbps down to under 46kbps. Disconnect the NIC and everything is 60mbps again. External USB and PCIe NIC's work fine. I WILL NEVER buy another motherboard with a Killer NIC on it. Poor audio shielding. If I'm in a game and connect my mic to the rear input, apparently I sound like I have a lawnmower next to me. I'm lead to believe noise from the GPU's is interfering with the creative onboard sound. It isn't the headphones and it only happens when playing a game but through all voice applications(TS3, mumble, and in-game for BF4 and R6 Siege), regardless of drivers(and yes I tried another PSU). If you read the MFR notes you're supposed to make sure to update the realtek drivers before the creative drivers. This doesn't help it, nor do different driver versions.

Overall Review: This is my 5th Gigabyte MB. I was practically a Gigabyte fanboy, but after I had two bad GPU experiences(GTX680, literally came with wrong firmware making it more like a 670 and ran hot compared to other gigabyte 680 after they provided me with a custom firmware to make it do what it was specced to do, & GTX980ti which they installed a bent as**d cooler onto and then proceeded to blame me for and they refuse to support) and now this. I expect I will be trying other brands in the future. MB: Gigabyte Z97X Gaming 7 GPU: x2 Gigabyte 980ti G1 Gaming in SLI with EK water blocks CPU: i7 4770k with copper water block, no OC at this time MEM: Corsair Vengeance 16GB @ 2133MHz SSD: Samsung 950 Pro 512GB M.2 PSU: EVGA Supernova G2 1300W

Pros: Speedy! Takes a whopping 1 second to load Windows 10! With my previous 3x Samsung 840 Pro RAID0 config it still took ~6 second to load windows. Wait, I spent how much? :S

Cons: I had issues trying to install Win7 from a disc. Dozens of BIOS configs, couldn't get my motherboard to recognize this drive for the life of me, even with newest drivers and BIOS. Could be compatibility issues with the newest drivers, OS, motherboard, or the fact that I was trying to install via disc. I shoved a Win10 flash drive in and away it went with factory defaults.I had other issues with my MB too so it'd be unfair to blame it on this device as it works perfectly at this time. Only con might be that my motherboard requires Windows boot loader be primary in the BIOS(rather than this drive) otherwise it won't boot, and it feels like it could boot faster if it didn't need to do this. Seems my previous SATA3 Samsung SSD's didn't need this so it's probably something new with the M.2 port. Again, probably more of a motherboard/port issue than this SSD.

Overall Review: MB: Gigabyte Z97X Gaming 7 GPU: Gigabyte 980ti G1 Gaming, 2x SLI with EK waterblocks CPU: i7 4770k with waterblock SSD: Samsung 950 Pro 512GB MEM: Corsair Vengeance 16GB @ 2133 PSU: EVGA Supernova G2 1300W

Pros: *Spacious. Fits oversized GPU's and has plenty of room for SSD's/HDD's. *Sturdy. *Ventilation and radiator mounting options are great. (120x(up to)360mm top, 240x240mm side, rear 140x140mm) *Built in holes for running hose to an external radiator. *Lots of options and space for cable management. *Collects surprisingly little dust for having no filters.

Cons: * Half of my fans started making noise(ticking, etc) in the first 1.5 years, so I've since replaced all but the front intake. * Mine weighs better than 80lbs and I don't even have waterblocks on my GPU's. Don't think I'll be taking it to the lan any time soon. * My case came damaged from the MFR. One of the feet was shoved over an inch into the bottom of the chassis with no damage to package. I chose to re-align it myself rather than deal with shipping.

Overall Review: If you're using this for air cooling, you may consider purchasing some filters, which will of course decrease your airflow, but it depends on how dusty the environment is and how often you want to clean it. It's spacious, although with all of the stuff I have in it, the motherboard mounting(full ATX) should've been moved up an inch. I have a 360mm rad on the top of the case which means I have to mount the PSU on the bottom and I can't get more than two GPU's into my MOBO due to verticle limitations. I also only have access to one PCIe port. If you have some really thin GPU's, a slim PSU, or a motherboard with different slot orientation this may not be an issue. If you want more than dual SLI though I'd recommend the HAF935 with a HAF915 stacker to stick your PSU in.

Pros: I've had this for about a year with no issue. This is the nicest power supply I've owned to date. Even comes with a bag for all of the modular cables. Provides more power than probably anyone needs in an Nvidia/Intel gaming rig short of 4-way SLI. See other thoughts; I list power demands of my components under benchmark and real world conditions.

Cons: Nothing to do with the power supply, but if you get a CM product with mail-in rebate, don't hold your breath. When I built my rig I had 3 components with CM rebates. I only ever got 2 of the 3 and it took them 6 months to fulfill.

Corsair Vengeance 2133 RAM draw during benchmark: 10-29W Fan controller +12W (8 fans(6x120mm, 1x140mm, 1x230mm@100%) RGB LED controller 2W Power draw from computer at idle: 78W(includes all previous components, two XSPC D5 water pumps @ 1900RPM, 3 Samsung 840 Pro's striped, Creative SoundBlaster Z sound card, & one BDRW drive). Max theoretical power draw on PSU: 538W (579W drawn @ 93% efficiency) Gaming operation with everything set to max playing Crysis 3 @1440P: 437W (470W drawn @ 93% efficiency) Note: these power levels are based off of the power that the PSU is using, the output should be 80-93% efficiency according to unit specifications, so power output may in fact be less than noted. Calculations made assuming that PSU will not be more than 93% efficient. All that being said, you generally want to shoot for a PSU capable of at least +30% over what you expect being able to throw at it. This will make a good PSU last longer and improve system stability.

Pros: This card paired with my older version GTX680 in SLI have doubled my performance on synthetic benchmarks. Real world application - the improvement is similar. If you already have a GTX680 , decent PSU, and don't want to blow $700 on a GTX780ti for similar performance, this is a pretty good way to go. If you aren't trying to SLI this with an existing card, there is probably another card that is more worth your time.

Cons: Specs are not accurate. This is my second Gigabyte GTX680 that I am now running in SLI. Newegg copied the spec page from my first card. htp://www.newegg.com/Product/Product.aspx?Item=N82E16814125448 According to GPU-Z and unigine benchmark programs, this card has a memory clock of 1350MHz(compared to 1502MHz) and memory bandwidth of 172.8 GB/s (compared to 192GB/s). Aside from those details and the heat sinks, these cards are pretty much the same. The length is specced off the old card to include the oversized heat sink, this card is really only the length of the PCB at 10", maybe 10.5" if you count the part that screws to your case.

Overall Review: Ah yes, heat sinks... this cards heat sink is about half the size as my older model 680. It may not be bad in general, but it is definitely worse than my other card. Current positioning they run close to the same temps. If I move them around the other way, this card is 20C hotter. Right now they don't get over 65C on multiple runs of unigine heaven at max settings on 2560x1440 resolution. Idle temps are around 24C-30C. Note that I have fairly good airflow and these cards vent out of their sides and into your case. Computer specs - CPU: Intel Core i7-4770K Quad-Core @3.5/3.9GHz turbo.
