CORSAIR - Hydro Series H100i RGB Platinum 240mm Radiator CPU Liquid Cooling System with RGB Lighting - Black/Silver

Overall It’s a great cooler if setup properly. I just wish they mentioned some where on the instructions you need a gold power supply or a power supply with all wires in your sata cable or your cooling block will not light up. Don’t be like me buying a cheap bronze power supply and trying to figure out why I have lights on the fan but not the cooling block. Now I’m rewiring my whole computer again just to get this thing up.

Hi there. Big Corsair fan here. In my old build, I used a H100i for 5+ years, and it worked like a champ, with overclocking and a lot of high end gaming. Just built a new computer, and chose this as my AIO due to really good past interactions with various products. New computer is also with a Corsair case and Corsair ram. Unfortunately, there happened to be a manufacturing flaw in this specific unit. The plug where they fill the reservoir during manufacturing had a slow leak, which was dripping coolant down onto my fans/GPU and making a mess of my case. It was so slight, it took some sleuthing to figure it out. In any case, I contacted Corsair for an RMA, and am waiting to hear back. Due to the rest of my computer parts being slow getting here due to Covid and such, it took me a bit to finish building my new PC. By the time I'd noticed this it was 2 days past the return date for Best Buy, unfortunately. Nothing else was damaged or anything like that. So currently waiting to get another shipped over to me from Corsair. I'll simply ask for the same item, as I know their quality is generally really good, and this is probably just a one-off.

Got this for $100 during a sale but for that price this thing definitely feels great and well built. Cooling wise I’m able to overclock my 9600k while not having a personal heater in my room. Great aio just need my 3070

Please make sure you measure this out. I made the mistake and purchase the Corsair 220 case with RGB. The downside was the Vengeance memory, they are a bit tall along with my TUF 580x board. I had to mount this vertically.

Keeps my 10850k under 60 under load. Easy to use, easy software. Make sure to go hose down when installing

Keeps my 2600x cpu nice and cool when over clocking.

I recently wanted to update my gaming PC so one of many items I picked up this liquid cooled and installed it and it was outstanding!

After opening the box and going through the pieces, I can’t help but wonder why the water block/pump doesn’t have some kind of protective cover or something. The copper plate is scratched up and the thermal paste is smeared. It looks like there’s some kind of plastic piece that might act as a protective covering, but it wasn’t on and when it doesn’t stay on when I tried to see if it fits. I’m concerned about the scratches in the copper plate and the smeared thermal paste.
