I Love this item ,but !! as a pc builder of many hundreds of custom pc's it lacks on looks in some ways .its is fiddly to fit with one person unless you use masking tape to hold the back plate on .i could rant on about stuff here so i wont . it cools a cpu well ! it is not outstanding like a full cooling system but for the price it does just fine to very well indeed !what can i cool with it ? my CPU on an AMD AM4 SOCKET 12 core 24 thread Ryzen 9 3900X /3950X .power usage low as it works straight off the cpu fan an uses low power for fan and pump which is onto a fan on the exterior which cools the cpu plate directly almost but collectively even more .the look is okay and this will fit inside many cases that are 280 mm radiator capable .the length size is bigger than280 in length so please look at this if you intend to fit it in a smaller case .i used the corsair air 540 case to support it . however a bunch of new cases may support this cpu cooler .i even had it in a budget tiny compact Ionz case top mounted with some clever holes drilled in the pc case top . this was certainly temporary and as i love tinkering on it was very easy to do .so to temperatures . i had this cooling a 3700X at one point also . just to test it out .i decided to just leave it on normal settings for 24 hours and it was just fine with no cooling issues . on all teh cpu's i tested it on . its been 6 months since ive tested it now . so my review is sound advice .i willl not give you exact temps as this may not reflect the case and pc et up you may have .however the cpu cooler works well . you will notice a slight difference in noise compared to the 240 or even the 360 versions with the bigger 140 fans it uses here just because they are bigger so spin at lesser speeds in general . hence the purchase . as i did not want something like a garden blower in my pc .so the temps were slightly lower than the biggest AIR Noctua NHD 15 ? i think it is called . cant recall of hand ? but the good one . you will ll know it if you just want that option instead . or have room for it on your motherboard . where you have to watch the ram cooler height carefully .so with that said the thing works and works well . i bought 2 of these in total to cool my friends system too . so pleased but worry about cleaning dust out that tiny fan if or when it builds up as i think a small long bristle paint brush may not do it as well when it comes to regular dusting of the cooler in general .i would say a real value bonus for this price which unlike the very old versions from 2014 /15 which were terribly noisy . so got junked until some clever sod came up with this little beauty . the 280mm is the way to go if you happen have room in the top of your case to fit it . noise is low but will ramp up a bit under editing and multi core usage maxed out . which i done for one day also . sad fact is this is a cheap cooler at this price and you may not regret it . but as time goes on we shall see .

Installation is straightforward with standoffs screwing into a backplate and two mounting brackets fitted to both the standoffs and pump block, then thumbscrews secure the two together.The radiator comes with the fans pre-installed in a push configuration, but it's easy to swap to pull as I did for front of case intake. Bear in mind this is a thick combination, with the fans and radiator coming in at 65 mm thick.The fan cables are very short, but connect to the pump block via connectors coming out of the tube braiding. If you want to control the fans independently to the pump using your motherboard I'd recommend getting PWM extension cables or a long splitter.As for the tubes they are very flexible and long enough to easily clear my GPU with the tubes bottom front with room to spare.As for performance, I mounted this to an overclocked Ryzen 7 5800X using the offset mount configuration and I am extremely pleased with the performance. With the pump running at 70% and fans at around 900 RPM (very quiet) my CPU idles at 30° or so, and peaks at 65° in gaming without any increase in pump or fan speeds and thus noise. When stress testing my peak temperature reaches 75° at 100% pump and fans, which are reasonably quiet given the performance.The VRM fan mounted to the pump block is quiet enough for my preference, but can be disconnected easily if required. I don't think it makes much difference to temperatures since I have good case airflow regardless. Bear in mind you might not be able to disconnect it when the cooler is mounted as the cable connector sits under the pump block housing.To summarise, the performance is superb, it is very quiet and has an excellently designed mounting system. I would happily recommend this to anyone looking for a good 280mm AiO, and at a more reasonable price point than most of the other well known options.

Too big to fit above the motherboard unless using a large case, but works beautifully set to intake in the front of my case. Even under load my CPU doesn't reach over 70°C with minimal noise. Having the fans connect to a plug on the radiator makes for easy cable management as there is only one lead to plug into the motherboard. A robust AIO for robust cooling.

This is not the cooler fault but my PC case H510 said it supports a 280mm radiator but the front panel cable is in the way of the radiator which forces me to install the fast deep in front of the case which restricts even more airflow.My Ryzen 3900x utilised all Cores and Threads for stress test only hit 75c maxTurning SMT off the temperature only hit about 62c while having a 4.375hz overclockPro:- Great performance, properly overall the best AIO cooler outhere.- The cooler has a premium feel.- only need 1 header to plug install motherboard makes life pretty easy.- Not silence but nowhere near noisy, having a headset on completely block out the noise and your graphic card properly the one that's causing the noise.- competitive price with other AIO coolerCon- Installing without taking the motherboard out is painful, partly because nothing to hold the backplate and there's no lock-on system to help you guide the pump into the socket, since your one hand properly holds a screwdriver, so you got nothing to hold the backplate and the pump itself.- No paper installation guide, one simple paper which says AMD or intel use this one, this screw go here and that screw go there would have saved so much headace.- No label on the screw pack, you simply don't know which to use if this is your first time or new to installing AIO cooler- Screw bag is not zippable, you can easily mix them up or might lost important screws.- No RGB for eyes candy, might not go well with some certain PC theme.
