Cooler Master V1000 - 1000W Power Supply with Fully Modular Cables and 80 PLUS Gold Certification
  • Verified Owner
  • Owned For: more than 1 year

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.

Other Thoughts: Measured PSU power draw increase from idle during benchmarks:
i7-4770k @ 4.4GHz - Prime95 small FFT's stress test: 133W
Gigabyte GTX680 4GB OC(two-way SLI@1202MHz core & 6508MHz MEM)GPU draw during unigine heaven, max settings @ 1080P: 295W avg, 325W max.
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.

COUGAR CF-V12HP Vortex Hydro-Dynamic-Bearing (Fluid) 300,000 Hours 12CM Silent Cooling Fan with Pulse Width Modulation
  • Verified Owner
  • Owned For: 1 month to 1 year

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.

Other Thoughts: 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.

GIGABYTE GV-N680OC-4GD GeForce GTX 680 4GB 256-Bit GDDR5 PCI Express 3.0 x16 HDCP Ready SLI Support Video Card Manufactured Recertified
  • Verified Owner
  • Owned For: 1 week to 1 month

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.

Other Thoughts: 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 -
