5 out of 5 eggsGREAT

Pros: Super easy to install, comes with Cam software.
Have this on a AMD 9590 at 5.0Ghz at idle 23C and under full load with Prime 56c, these to fans and grill are friggen awesome as heck. this is by far the best CPU cooler out there.
I have a antec case with 2 top 140mm fans , all i did was install on top of them, now i have 2xpush pull.

Cons: None ....the instructions could have been done better, but it wasnt hard to figure out

Other Thoughts: Be sure to have 2 x 140mm fan spots ready, THIS will not fit on a 120mm.

5 out of 5 eggsX61 Great AIO used on first build ever

Pros: Keep my 4790k@4.4 cool. idles at 20 to 25c depending on room temp

was easy to install in the S340 case. was my first build ever

can change the color of the LED lights

Cam software has improved sense I purchased in Feb of this year

Cons: had a clicking noise that came from the pump when I first installed I fixed by changing the cpu fan from DC to PWM and manually setting the fan speed in bio to full and the sound stopped and I have had no more noise sense. using Asus Maximus VII Hero MB

Other than that none so far in the past almost 3 months now

Other Thoughts: I switched out the stock fans from the start with the Noctua NF-A14 industrialPPC-3000. I keep the fan speed at 30% about 1080 rpms, in CAM and they make little to no noise from what I can tell, anything over 1200rpm is noticeable, at full blast they are noisy. Under full load for 3 hours the 4790k @4.4 never got hotter than 61c at 30% fan speed.

5 out of 5 eggs

Pros: Cools great.
Silent operation.
Great customer service.

Cons: A bit annoying to clean between fan and radiator? Not really anything special to this unit, so I won't be taking off any stars,

Other Thoughts: Customer service didn't require anything but proof of purchase, and sent me two new fans. The original pair made a great deal of grinding noises: the new pair leave nothing but air flow as the sole generator of noise, and there's little to nothing to be done about that. If you see this NZXT, consider packaging your fans in plastic bags: two of the rubber feet fell off during shipping, and I only managed to find one. That being said, I simply used one from the pair of fans you didn't demand I return, so definitely nothing done wrong on your end. Seriously, the simple acceptance of what I had to complain about and immediate resolution is nothing shy of amazing.

I personally recommend pulling air through it rather than pushing. This will allow you to vacuum reversing air flow without removing fans and putting them back on. I have a previous 3-egg review, was unable to figure out how to edit that one to be 5-eggs.

1 out of 5 eggsPiece of JUNK x60

Pros: claimed to be the best in performance at the time of purchase.

Cons: Software is glitchy as hell. cam is better as of the recent update but a year down the road. still the led wont work for the cam software. had a big issue with no temp readings and fan control til i got that sorted.

Other Thoughts: i got 2 of the x60s cuz forums stated it had slightly better performance then corsair. my first 2 leaked right out of the box, didnt even have to hook them up. rmad both of them no problem thanks to the good help of my buddies over at newegg. love you guys. after i received my new pair of x60s hooked em up got em running. had one for my cpu and other for my graphics card using the g10 bracket. well one one of the loops the wires frayed and snapped clean off rendering 1 loop useless. threw it right into the motherflippin garbage 140 bux wasted. now after about a year down the line i noticed an odd sound comming from my case almost sounding like coil whine. unplugged all my fans graphics card then finally the x60. YARP that odd telephone pole buzzing was comming from ye old nzxt. my buddy told me about this trash but i put my faith into this product because i really like the cases. i dont even think i can rma or return this junk a year down the road. hopefully this review helps somebody in the near future. stay away from nzxt . corsair bro... corsair

5 out of 5 eggsCAM Is Real Good Now

Pros: The newest version of CAM is outstanding. It's version 2.1.11. I never had many problems with any versions of CAM but this one is by far the best. Temps are correct, all hardware is detected and the layout is a major improvement over some of the previous versions.

My android devices can now pick up my computer readings with the new android CAM app. It works fine. NZXT has done a great job with this CAM version. I've written a few reviews already on the X61 and now I'm convinced it's even better than ever. No complaints out of me. The Kraken is outstanding.

Cons: None

4 out of 5 eggsGreat but doesn't work with all NZXT cases

Pros: Keeps the system cooler than just the fans
Very quite
Great price

Cons: Doesn't work with NZXT Phantom case for mounting.
Thought it would work since it is made by the same company, but it doesn't. So it has to sit on top of the case without being secured down.
My fault for not double checking that it would work with the NZXT Phantom (Full) case.

5 out of 5 eggsAlmost Silent

Pros: Silent run on performance setting with 4 Vipers ( AK-FN063 ) in push/pull running 32c at norm. also don't change the thermal material on it I have with Arctic Silver 5 and gitting same temp. so don't wast your money whats on it is good

Cons: Had to buy 2 more fans as well as replace the two that came this it . never used the ones that came with it

Other Thoughts: I was using a H70 with a 32mm shound and a Delta ( AFC1212D ) in push/pull setup and gitting same temps.Put it was not ,was not SILENT. Had they have inpro, the rad on this as they did with the X41 Ithink theyed have a hands down winner as well as about 4-7c temp drop.Planning on installing shound on this to see if I can git temp to drop,also will mach it with the H110i with and with out shounds. PS I think any good rad temp need to be 25-27c at idel. 4770k@4.4/1.210v with 2400Hz memory stable allday long. will update in a week

5 out of 5 eggsWorks like you hope

Pros: I wanted an easy-to-install and use water cooler. I've had a few of them and I thought I'd give this one a try based on reviews here and on YouTube. None are really that hard to install, but this one was a breeze, esp. if you are planning to install at the top of your case. I can see how it might be finicky to install at the back of some cases but that wasn't an issue for me (used an NZXT case). It works perfectly fine. I don't overclock my i7-5820 so I'm not too worried about temps. When I start tweaking, we'll see.

Cons: None yet.

Other Thoughts: The CAM software to regulate and monitor conditions isn't all that useful. I never use it.

5 out of 5 eggsExcellent water cooling option

Pros: I got this to fit inside an NZXT S340 & cool an overclocked i7-5820K @ 4.5ghz. Does a fantastic job. Keeps idle temps at 38C while under 100% full load stability burn tests it hovers in the low 70s. CAM 2.0 software to manage the fan & pump speeds works well. No complaints!

Cons: The CAM software only allows you to plot six custom liquid temp to fan performance points. Might be so they could sell their additional expensive fan controller I don't know. Not really a deal breaker or anything I just wanted more fine tuning options.

Other Thoughts: Excellent cooler, like it better then the H100i & H110 packages from Corsair. (have worked with both quite a bit) While not required I'm going to buy additional fans to put this in a Push/Pull config. (it already comes with the power adapters to run four fans built into it's wiring) If you're thinking about buying this for anything but high end overclocking this isn't required at all but if you want those 4.5-5ghz clocks it's something you should think about while ordering.

5 out of 5 eggsSubzero.

Pros: Installed this cooler for my Core i7 4790k CPU - idle temps are between 21-25C on all cores, despite a stable 4.8Ghz overclock. Max temps with Crysis 3 on Ultra settings and bunch of other applications running (Dolphin emulator, etc.) were between 45-52C. I am extremely impressed with this unit. Takes a bit to install (You'll need to rip out your motherboard to install the backplate, etc.), but highly worth the time and effort.

Cons: None. Absolutely none.

Other Thoughts: The ability to change the LED color on the pump makes me ecstatic; it maintains the red/black theme my entire PC is built around.
