It seems really good, so maybe I am doing something wrong.
Amazon Customer✓ Verified Purchase•November 13, 2023
Update - (last 3 pics added) - I Frankensteined my PC case and move the radiator to the front of my case. I believe that has dropped the CPU temperature by 4 degrees on average. I moved the radiator in support of my new Aorus X570 Pro WIFI, but I think I would have had room for it after all. But, I am glad I move the radiator.
---------------------------------------------------------------------------------------------------------------
(I hope you can see the pictures ok)
I have added some before and after pictures. I am hoping you can get a feel for the space I had available for the radiator (not much in this case ((Rosewill TYRFING ATX Mid Tower Gaming Computer Case)).
PC:
1. Ryzen 5 3600X
2. B450 Tomahawk 3. Vega 56
4. DDR4 16 GB running at 3200 mhz
5. 650 watt PSU
6. 512 GB M.3 (PCIe) - (I also have an HDD 3TP)
7. My first build - I know that the 3600 would have been as good, but I should have gotten the 3700X (oh well)
I will give you my pros and cons. I am not going to hold the size of my case against the AIO.
PROS:
1. Everything fit well in my case. I did spend a half hour getting all the wire pointed in the correct direction (you will see why that is important) - I would suggest you do the same.
2. It seems to keep the CPU pretty cool. Cinebench 20 drives the temperature up to the mid-70's, which is way better than the
3. It took less than 30 minutes to install and test. I spent a couple hours with my BIOS getting the cooling/noise ratio where I want it.
4. I was glad there was just about the perfect amount of tubing. Any more and I would have been tucking tubing in places I did not need it.
5. I really like the way it looks, and the Cooler Master label showing. It is not close to an open loop, but better than in fan I have seen.
6. I think the price I paid was really reasonable.
CONS:
1. I was expecting the system to be cooler. I do want to run overclocking, and for now, I have focused on my Vega 56 (great card to work with). Mind you, my system does not go above 80 degrees, but I have never seen the low temps people talk about.
2. The included thermal paste as a let down. Cooler Master makes some really good thermal paste, but that was not included.
3. I tried to use Cabonaut with no luck. I could not keep the the pad positioned and I tore the pad during the installation (oh well - not sure I can really blame Cooler Master for that).
4. I have my system cranked up pretty high, so it is pretty noisy. I run the pump 100% of the time. I cant think of any good reason not to run the pump (I have run the pumps in my aquariums for 15 years straight without an issue and I dont see much difference).
I dont have the best looking system by far, but I am proud of it. My AIO is a major reason for my pride.
I hope this information helps.

great budget aio, the fans suck tho
Sam✓ Verified Purchase•October 31, 2023
big upgrade from hyper master 212 that was in there before,
allows me to overclock my i7 9700k to 5.1ghz, great temps either idle or under load. the highest ive seen it was 75c
however the fans really suck, due to my case i wasn't going to be using them on the radiator because then the rgb wouldnt be visible so i just used cheap 1200rpm cooler master fans, have since ordered noctuas. i decided to mount one of the fans as exhaust in my case and i had a rattling noise. i really thought it was the pump for a while but removed the rgb fans and my case is now whisper quit and cold
UPDATE: so it seems like the noise was the aio, so what i did was set the aio as acurve like you do with fans and now my system is very very quiet, even at idle. before there was a faint hum at idle and i thought it was my psu fan. now it's set to around 1200 rpm at idle instead of 2200 and it ramps up when my cpu gets hot. now i can't hear it at all under load because of the fans

Great Value for the money
Jack Goodwin✓ Verified Purchase•September 27, 2023
This AIO was EZ to install Note the hose are a bit shorter than some other units however I didn't find this to be an issue. there is absolutely no sound above the fans which are quite, the temp avg is 30c and 36c under load for 45min. So it does the job it is intended for. Paid $60.00

Fantastic value

The media could not be loaded. I just purchased this for my sister's birthday since she needed a new CPU cooler (stupid intel stock coolers). She's never had an AIO before so I thought this would be some good brother sister bonding time. I was right. For the price listed on Amazon you can't go wrong. It looks great! Build quality is very good for this price point. The RGB is decent enough to make you feel like your money was well spent. The RGB comes in many flavors and colors, so there is something for everyone here. My only complaint is that although it's easy to control with the included RGB controller, cable managing it properly can be difficult for newcomers. The installation was easy, just slap the backplate on, attach a bracket for intel chips, thumbscrew it on and you're good to go. Performance wise, it's not the best, although you aren't really paying for the best now are you? For $70, it keeps the cpu adequately cooled. I ran prime95 high head and load stress test for 8 hours on the AIO attached to my sister's i7 8700, and average temps ranged from 65c to 75c. Although with the pump on full blast, it was LOUD. Sounded like a buzzing bee, however I doubt it sounds like that under a more normal gaming load.
Bottom line, it's a great addition to any pc build that needs a better than stock cooler, and you don't want to go with an ugly air cooler. Installation was easy, RGB looks good, cooling is decent, and it's cheap!
