Corsair Hydro X Series XD5 RGB Pump/Reservoir Combo - D5 PWM Pump - 330ml Reservoir - Ten Individually Addressable RGB LEDs - Temperature Sensor - Black

Alright, buckle up because I went all in on Corsair’s waterblocks for my CPU, RAM, and pump, and let me tell you—I’m never going back to EK again. I’m talking about a triple threat here, and Corsair knocked it out of the park.First off, the price difference between Corsair and EK? Stupendous. I felt like I was getting away with a steal. But the real kicker? The pre-applied thermal pads that aren’t crap. No more scraping off factory gunk like a caveman with a butter knife; Corsair actually gives you thermal pads that make installation feel like a spa day for your PC. Life-saver? You bet!Now, I’ll admit the pump was a tad pricier than I’d have liked, but after a used one leaked like the Titanic in my rig, I wasn’t about to redo my hardline tubing. Corsair’s pump is rock solid—whisper-quiet, no drama, just cool, consistent flow like it’s training for a marathon.All in all, I purchased all three: CPU, RAM blocks, and pump, and I’m writing this single review for all of them because they’re that good. Quality is top-tier across the board, and I’m officially Corsair-converted.EK, who? With Corsair, I’m finally sleeping soundly, knowing my rig looks and performs like a million bucks without costing anywhere near that. Five stars to Corsair for water blocks that are surprisingly better, better-priced, and ready to turn your PC into an absolute liquid-cooled beast!

What I like most about this pump is that it comes with all the hardware you’ll need to install it in a case. My last pump was cheaper, but buying the extra mounting hardware was a pain and expensive. I loved that this pump came with all the screws and mounting brackets. It’s near silent at lower speeds, but can get a little loud at higher speeds. I keep mine at about 20% except for when I’m trying to get air bubbles out of the system. It should be clear that this pump does NOT require the iCUE Commander Pro for basic operation. I believe the manual says it does but that’s not correct. The motherboard can control the pump speed and even set the LEDs to a solid color if you have the right RGP connector. The iCUE adds the ability to use the included water temperature sensor and it greatly increases the amount of RGB customization options. I enjoy using the water temp sensor to measure the performance of my system and to adjust radiator fan speed based on those temps rather than the CPU temp.

I came from the Corsair AIO 280 which had been a great performer for a few years now. But as I started to notice irregular temp swings, I thought it's time might be up. So I took the plunge into custom loop, and Corsair made this really easy. I went with the hydro X series, soft tubes, still 280 setup, on a 12700K pushing 5K-P/3.9K-E all core hitting around low 70'sC peak, around 30-33C idle. Around 65C after hours of gaming. Fittings worked great, easier with soft tubes for sure (better for beginners). Really quiet, works super well. Also, will work with ICUE commander XT (pump goes on fan header 6, then pick from dropdown menu).

I love the look of this res/pump combo and it's powerful too with 800/L an hour. Its mounting is pretty versatile. Downside, I wanted to monitor water temps, only to figure out if need to buy another product. Never did that and it works fine, I just got off CPU temp. I haven't had leaked problems. The build quality is alright, the plastic looks kind of cheap but overall fine. Cooling is fine, I mean it pumps the water as needed.

I have been using it for more than two years and it has been perfect. I have used it continuously for almost a year for mining cards and another year for personal use; the best Corsair product so far.

its pumping along been a month or 2 and its been working great hopefully it stays this way :D

Does what it is designed to do. Expensive but probably well worth it considering the other options on the market.

Needs a specific hub to control it's flow rate. It did not last more than 8 months before the pump just stopped working. If you don't want to use a Corsair fan hub and their fans steer clear of this mess. It's covered in crappy proprietary ports so you can't connect your fans from other brands. Their iCue software can't stand other software even reading data from their devices, software like hwinfo will nerf your setup and it's thermals. I'm giving mine away and never using corsair anything again.
