LEAKED ! 11/7/2019 6:58:05 PM

Pros: 1- The system worked fine for 11~12 months with no issues just not the best cooling temperatures.
2- Easy to install
3- AM4 bracket came with it.

Cons: it leaked all over the horizontal motherboard GA-ab350-Gaming destroying everything including the dual DDR4 Rams

Overall Review: when I was building my system I was paying attention to the positive side of reviews neglecting any bad possible ideas... and the worst had happened.

Good performance and no leakage 11/4/2019 11:06:28 PM

Pros: The product arrived without any physical damage or cosmetic imperfections.
Didn't have any leakage from 2 years of usage.
Pumps are longer than expected.

Cons: The fan could be a little better. Had to change to Noctua's fan for better cooling.
Not really a con to particular product, but i wish you could refill the water easily with any AIO.

Overall Review: Overall, It's pretty good for the price.

Good product - Terrible customer service 2/19/2019 4:00:11 PM

Pros: Works fine, looks nice. Has a decent warranty if you have a good sticker.

Cons: Warranty entirely dependent on a piece of polymerized paper with adhesive on it. If the valve it is covering failed, the sticker could fall off land on a fan and die that way.
Customer support is ridiculous. Sticker is more important that customer service or vendor's shipping costs.
Sticker could easily be damaged by reaching in to a small space to troubleshoot a bad drive and rubbing your watch on it.
Prioritizing a way to weasel out of a warranty over the customer is not good business.
I bought an AIO CPU cooler not a sticker.
My son (2.5) loves stickers and could easily void the warranty just by being a kid who likes to play with stickers
The design is compact with tense water lines that could easily cause the radiator to move harshly in a way that could damage the sticker but not cause even a scratch on the paintjob

Overall Review: I received a functioning, brand new unit with a scuff on the warranty sticker. This is a flimsy sticker that goes over the sealed water inlet intending to warn you the warranty will be voided if you try to try to mess with it. The sticker must have got bumped during packing or was applied poorly. There was no sign of tampering. I emailed customer support with a few pictures and asked if they would honor the warranty if I had any issues. Returns are a hassle and this minor defect in the sticker does not warrant the waste in return shipping, driving to the UPS Store, sending it back, waiting for the return to come, etc when the part is obviously fine. I explained that to support yet they still advised me to contact Newegg and return it. Well I promised that person a bad review for his or her complete lack of understanding of how minor the issue was, a partially broken sticker, how much of a pain it is to return something that is already installed, my time is not free, Newegg's shipping cost to return and send a replacement is not free and their insistence on a flimsy sticker placed on a non-flat, multi component surface is fundamentally a bad solution.

All I needed was for them to say OK, I trust that you just bought this. We will either honor the warranty if, in the rare case that the device fails or we will send you a new sticker and ask that you send a picture of it installed and then consider the product under warranty. Instead it was contact the seller for RMA, uninstall it, Pack it up, bring it to the shipping place, wait for the return to process, wait for the new one, cross fingers that almighty sticker is undamaged, profit?

If stickers are so important I recommend the following:
Put the sticker as you currently have it. Add a plastic/polymeric cap that is the same color and that slides over the whole valve assembly. Put another sticker on that saying warranty void if cap removed, but don't void warranty for real unless original super sticker is damaged.

Pros: keeps processor cool while it works, looks nice

Cons: didnt even last a year before one of the seals wore out and leaked coolant all over my GPU rendering it a useless paperweight. now I'm out a cooler, and a $260 graphics card.

I really like the mounting system - easy to work with 11/21/2018 1:03:14 AM

Pros: The Deepcool Captain 120 EX does a good job with the i3 processor. Idle temps are around 27 C and I have not seen them go higher than 35 C. The tubing is stiff and depending on the location and dimensions of the case, may make you get creative with the positioning of the unit. In the NZXT S340 case I used, I put it in the front of the case and placed the fan in a pull configuration. Worked out OK but I did spend some time scratching my head over where and how to place it. I liked the way this product attaches to the CPU. The motor unit screws onto the two long bars of the mounting system with 2 screws. This makes it easier to juggle the unit when you only have to deal with 2 screws. The mounting bars are held on with 4 screw knobs that are easy to deal with.

Cons: Limited flexibility of the tubing.

Overall Review: I built 3 of these for my office. For the typical office / student setting they are fast and efficient with plenty of storage space for the average office setting – word processing, spreadsheets, quickbooks, and the internet. For 80% of users this would be a great PC build. Anyone who is going to do anything with music, video, or hard gaming would probably want something different. All the products below worked well together and I had 0 DOA products.

My under $800 build consisted of:
O.S. Windows 10 Pro - 64-bit
Keyboard/Mouse Logitech MK120 Desktop Keyboard & Mouse Combo BLACK
Motherboard 1151 GIGABYTE Z370 HD3P (rev. 1.0) LGA 1151
RAM 8 GB G.SKILL Ripjaws V Series 8GB (2 x 4GB) F4-2800C16D-8GVR
Processor Intel Core i3-8100 Coffee Lake Quad-Core 3.6 GHz LGA 1151
PSU Seasonic FOCUS series SSR-450FM 450W 80 + Gold
Case NZXT S340 Glossy White Steel ATX Mid Tower Case

UPDATE 11/20/18 - I now have used 6 of these in various computers. All are working and all are easy to mount. It's my go to AIO now. CPU temps are 27-34 while being used all a day in an office setting.

Cools great & looks great 5/13/2018 12:40:00 PM

Pros: This was my first aio that I had ever installed, and I ended up losing the directions! I was still able to install it correctly (double checked when I found the directions), so that should tell you something about the product.

Cons: None

Overall Review: I wish this product had different lighting modes, it only has a breathing effect

Does a great job for my overclock. 4/4/2018 10:41:57 PM

Pros: -Keeps my overclocked i7 7700k cool.
-@ 4.8ghz 1.3 core voltage.
-This cpu is known to run hot.
-Averages 68°-72° under full-load.
-cpu is not de-lidded.
-Easy to install.
-Looks very cool. The pulsating light on the block is a nice feature.
-Comes with thermal compound pre-applied to block though I still applied my own. (Compound hard to clean off, see cons section).

Cons: -The hoses are short. I don’t see that being a big issue for most people though.
-When I installed a new cpu I could not get the pre-applied thermal compound off of the block. It would most likely need a very strong alcohol cleaning solution like 70% or higher. I did not have any laying around so I just cleaned as much excess off as I could and made sure to apply more paste to the CPU and it works just fine. But if you take my block off right now it’s a mess underneath.

Overall Review: I was concerned that I would not be able to get the overclocked temps I wanted with the 120mm version. But price was an issue so I decided to try it anyway because it is cheaper than the 240mm.
I have been running my i7 7700k @ 4.8ghz, 1.3v for about 8 months now and it rarely gets any hotter that 75°. I run most games on the highest settings with average temps at around or 68°-72°. Some games spike a bit higher but it’s always temporary. This cpu is known to run very hot and I have not de-lidded so I am getting great temps with this cooler!
I cannot say that everybody would have the same results with this cooler on the same CPU, but if you can only afford the 120mm I can only tell you my experience. Of course a 240mm is the safer choice but don’t count this AIO out.

I would recommend this to any overclocker with a small warning that my results may not be the same you get. But my experience has been great.
