Review: Excellent Cooler That Fits In The Dan A4-H2O - This was exactly what I was looking for - it fits perfectly in my Dan A4-H2O. The packaging was easy to work through, and durable enough that I'm holding on to it should I ever uninstall this AIO. I put some Noctua fans on it, and it cools my 7800x3D excellently. Installation was pretty straightforward, there weren't a crazy number of cables to manage, and the tubes are flexible enough without feeling too Pinner. The RGB effect is pretty great as well. I would definitely recommend this cooler.
Review: Good cooler, but iffy connections to Intel motherboard - Had to reconfigure my PC's CPU cooling solution,and this product worked beautifully. The only downside was that the included Intel mounting did not take into account that Asus motherboards (at least mine) has the CPU cooling studs hard-mounted, meaning I could not alter the built-in cooling mounts for those in this kit. Luckily for me, the included AMD style bolt heads worked with my Asus motherboard's existing Intel style studs, and allowed me to jury-rig this item to work as intended. I have the Asus z790 gaming WiFi motherboard

### ⭐⭐⭐⭐⭐ Silent Pump, Great Cooling
*by C***D on December 29, 2023*

This cooler works great. I'm coming from TWO EK CR240 coolers that developed grinding pumps within a month. Installing this, the pump is dead quiet, and using the same fans (Phanteks T30) and same thermal paste across all of them, this runs about 5c cooler than the EK coolers. It could be the large difference is due to the pumps, which seem to have been defective. Either way, this cooler is dead silent and cools well. You don't have to use all of the RGB nonsense it comes with and deal with a big nest of cables, either. If you just want to install the cooler without fan RGB it's just the PWM pump header and the fan header on the mobo. You can plug the pump head in to any 2nd gen RGB plug on the motherboard, too. It's a very clean install overall.
