Lian Li Galahad 360mm High Performance RGB CPU Water Cooler White

I've been using this for over a year now on my last PC build. You can run it with the lights on or lights off but it's kept the computer cool which is what it's all about.

No use rating an item like this in the first 30 days. The more important question is, how does it perform in the long term?This cooler is still working against a Ryzen 7 5800X, 4 years down the road, in (by way of disclosure) an open-chassis Thermaltake Core P3 "case." Shortly after installation, I stress-tested it, running all cores at 100%, and it didn't reach 90C. I then just used the system normally, and 4 years later I stress-tested it again the other day and temps didn't reach 90C. Haven't touched it since the initial installation, just let it do its' thing.Yeah, as far as I'm concerned, this was worth every penny of the purchase price.

Seeing some of the best thermals I’ve ever had since switching to this cooler. Looks great, performance is fantastic on my i9 9900k overclocked at 5.0 gHz! Ran multiple one hour stress tests and we peaked 74 Celsius but always stabilized at around 64-66. Since the i9 runs hot I’ll take that all day. 10/10

I switched to the Lian LI AIO after buying a cheaper TT model. When paired with a quality thermal paste my 13900k runs great at 55c under normal gaming loads and 68c under intense loads!This is down from 73-75c with my TT snow 360 AIO. My cooler score in the Asus bios jumped from 165 to 187-190.

Beautiful AIO. Quiet and elegant. Wouldn’t pay anymore than retail for it tho. 149.99. Be patient and DO NOT support scalpers selling at inflated prices. Took me over 3 months til I found one at retail. GL to all!

The pump on this unit started failing ~3-4 months into usage, causing me to second guess nearly every other aspect of my CPU settings, and the build as a whole, to try to troubleshoot the abnormally high temps I was seeing. It wasn't until just recently that I realized the temps were slowly trending upward. Then this week, it completely stopped functioning and it can't even maintain the system temps while in the bios.After a bit of googling, it looks like pump failure and other flow restriction problems are a frighteningly common issue with this unit.I'm lucky the CPU has over temp protections, without that, it would have been destroyed.Even if I can manage to RMA it, there's no way I could trust the quality of the replacement at this point.BUYER BEWARE.Also: The AM4 mounting assembly is bad; like threw it together in a week bad. Instead of designing a proper bracket for it, they tried to repurpose the oem mounting bracket. The result is an exceedingly awkward and difficult install, which rewards you with bleeding knuckles and inconsistent pressure across the CPU.I would've probably been fine with it, if I only had to do it once, but I remounted it half a dozen times, while troubleshooting the high temps.

It worked well for about a year and then I had to replace it as it was no longer cooling the CPU enough.

UPDATE 8/1/2022Received my replacement pump & rad over the weekend and installed it right away. So far temps are all normal with hottest monitored being 70c when using default high performance profile in windows (when the old one went bad, I was using power saver and lowered cpu to 80% so temps wouldn't go up while working)Here's hoping that I don't have to have another update down the line.UPDATE 7/20/2022Have to add a star for Lian Li's customer support though. I submitted my claim and within an hour of having done so, received a response stating I would have a replacement (without the fans which is fine because there's no issue with those) in 3-4 weeks. I'll update once again when I receive it and increase the rating accordingly.***original below***Guessing either the pump went bad or something happened because my system is now struggling to stay below 70c when in use and CPU goes up to 90c when gaming and ~30% usage tops while GPU maxes out around 67c with 100% usage.I've owned this for a year now and maybe like 2 weeks ago i heard my fans kick up to probably 100% for no good reason just working on some excel files along with some gsuite usage. I decided to re-paste my CPU to see if there was something wrong with the thermals since I can't remember if I used my own compound or if the AIO had come with some on it already. Either way, my temperatures were still in the 70s while working and today when I was playing games, I saw and heard it going to 90 again.Will reach out to Lian Li and see what happens
