Pros: The blue is a nice blue....lol? The run great and smooth, very quiet..almost..calming..lol! I replaced all my rig's stock fans with 5 of these (1 at the rear of the case, and 4 on my h115i in push/pull at the front of the case. See my rig and build review in my other thoughts below for all the details. Buy them, they are worth it and the build quality is obvious. Love Corsair.

Cons: I replaced the blue plastic corner pieces with the red ones you can buy directly from corsair...did the same with the grey accent on the h115i...I think corsair should include these with these fans and the AIO for the price they charge for both. Show more love to your customers on the little things and you'll be amazed how far it goes when it's time to upgrade our rigs again.

Overall Review: My build if you want to see it all together: https://pcpartpicker.com/b/QVd6Mp phantek ethoo evolv TG, ax1500i, Rampage V Edition 10, h115i AIO, 5 ML140 pro fans (replaced all stock), 6850k, 2 1080s SLI, G. Skill 64gb 3200MHz, 950 pro 512gb, 850 pro 1TB

Pros: Works perfectly, pump made the sound some referred to here in the reviews but it went away within minutes after the air pockets got worked out on their own. Search for h115i noise on youtube if you want to hear what it sounds like. Please don't let this discourage you, this thing is amazingly beautiful, works great, and is obviously quality built. I replaced the 2 stock 140mm fans with 4 of corsairs ML140 pro blue led fans...I also replaced the blue plastic corner pieces with red ones to match the rest of the build.

Cons: The noise for the first few minutes. However my biggest gripe is the fact that when I installed it on my mobo, for whatever reason it wasn't making good contact with my 6850k (read my review in my system build link below in other thoughts for more info). I simply added more thermal paste and away we went without another single issue. Took an egg off for this issue, not the noise...but still not sure if this was because of the AIO, or the mobo, but I'm confident it's because of the AIO. Just watch your temps in UEFI/BIOS before loading windows...if you have the same issue I had, your temps will get to the high 80 degrees celcius very quickly...even with these problems, I still can't recommend it enough, I just think they need to apply a bit thicker of a layer of TIM to these at the factory.

Pros: None, plugged it in and booted from it onto my 950 pro 512gb. See my rig below in other thoughts.

Cons: None.

Pros: I had the original version of this mouse that I've been using since 2007. Replaced it with this one along with my entire 07 rig with the rig listed in my other thoughts below. Software was great and simple to use, and still believe this is the most comfortably designed mouse on the market.

Cons: None.

Pros: Brushed aluminium, mx brown switches, no gawdy yellow corsair gaming logo of days past. very comfortable wrist rest. can't recommend it enough.

Cons: Corsair needs a lesson in simplifying software. The software does the job but man, you need a degree to understand it.

Pros: 3200mhz cas 14 ddr4....those timings at this speed are rare. worked perfectly after setting xmp profile in my mobo (see other thoughts below). They are unbelievably beautiful and solidly built. brushed aluminium.

Cons: Not 128gb, price could always be lower.
