Thermal Results with noise normalized to 38.2 dBA

Finding the right balance between fan noise levels and cooling performance is important. While running fans at full speed can improve cooling capacity to some extent, the benefits are limited and many users prefer a quiet system. With this noise-normalized test, I’ve set noise levels to 38.2 dba. This level of noise is a low – but slightly audible – volume level.

Lian Li’s results here are simply fantastic, roughly on par with MSI and DeepCool’s recent 360mm AIOs.

No Power Limits Thermal Results

Without power limits enforced on Intel’s i7-13700K, the CPU will hit its peak temperature (TJmax) and thermally throttle with even the strongest of air coolers. For most coolers, we’ll measure the CPU package power to determine the maximum wattage cooled.

That is what I would do for most coolers. But Lian Li’s GA II Trinity Peformance achieves a level of cooling that many 360mm AIOs are unable to hit – it kept the CPU under its peak temperature in this workload. As such, I’ve compared the actual temperature of the CPU in this benchmark against the only six coolers I’ve tested capable of this level of cooling capacity.

With a result of 68 degrees C over ambient, Lian Li’s Galahad II Trinity 240 is just barely behind DeepCool’s LT720 and MSI’s S360 360mm AIOs here. This is an insanely strong result for a 240mm AIO, better than any 240mm AIO I have previously tested. 

The cooler does run a bit loudly at 48.2 dBA – but that’s quieter than all but one of the AIOs shown above!

175W Cinebench Results

Most coolers on the market are able to keep Intel’s i7-13700K under it’s peak temperature if the power consumption is limited. So for this test, we’ll be looking at the CPU’s actual temperature. As with the previous results, the Galahad II Trinity Performance 240 continues to impress with the second-strongest result we’ve ever recorded in this workload – beating the results of 360mm AIOs from Cooler Master, DeepCool, and MSI. 

But how about noise levels? Well, those are good too. At 41.9 dBA, noise levels are moderate but quieter than most of the AIOs tested here – only DeepCool and MSI’s 360mm run more silently.

125W Cinebench Results

The lowest power limit I test with Raptor Lake CPUs is 125W. This is a high enough limit to allow the CPU to maintain it’s base clock speeds even in the most intensive tests. And most coolers should be able oto keep the CPU below Tjmax here – even low-end coolers.

Really, thermals do not matter in this scenario. Even Intel’s basic stock cooler can handle a load like this with ease. Noise levels are the most important factor here. That said, with a thermal result of 37 C over ambient, the 240mm Galahad II Trinity ties for the second-strongest result we have recorded in this workload. 

But again, how about those noise levels? The 240mm GA II Trinity does well here too, with a reading of just 38.9 dBA when tied to the default fan curve of MSI’s Z690 A Pro motherboard. For those who prefer quieter operation, the noise-normalized results shown previously demonstrate that this cooler still retains significant cooling power even when set to run quietly.

If you’re looking for a strong 240mm AIO, you can’t go wrong with Lian Li’s Galahad II Trinity 240mm. It’s the strongest AIO of its size on the market, and it has a very reasonable price of only $119.99.

I never imagined that a 240mm AIO would have this level of cooling domination. Lian Li’s Galahad Trinity II Performance 240mm managed to sidle up to or outperform 360mm AIOs I had previously considered among the best on the market.

    Lian Li is definitely a rising star - I just did a build with their 216 case and it is amazing how well thought out and well built it is.

    This vague post could've been more helpful with at least a few examples.

    The "pump seed" in the "Specifications" table is funny as a double entendre,

    I did not even catch that, I found the other 2 before it. Hilarious!

    "The inner diameter of the water tubes has been increased from 5.8mm to 7mm, increasing the total volume of liquid by roughly 20%, which allows for better heat absorption."

    It's not the volume that has influence on heat absorption! I could have a bucket of cooling fluid but if the flow and absorption in cooling block/ discharge heat in radiator aren't up to par it will be a bad cooling system. It's the flow of coolant and the delta T over cooling block and radiator that makes an AIO-cooler good or bad. And the rule is that "to" is always bad (as we say in dutch). So it really means the balance between flow and Delta T has to be exactly right to have a good cooling system. In this case I think they upped the rpm of the pump and enlarged the hose (and also changes in block and radiator ofcourse) to get a higher flow and keep the Delta T in block and radiator as small as possible. And here to small ain't good and to large ain't good either, every part must be in balance to make a good cooling system

    We have to list a "con" for our articles.

    Personally, I don't feel that there really are any "cons" for this product.

    This is going to be a bit of a long one, buyer beware of these new Lian Li products.

    @Albert.Thomas Did you have any issues with either version of the Galahad trinity II?

    I bought the 360mm Galahad II Trinity Performance to replace my 360mm Coolermaster ML360R that I had before because it was getting long in the tooth for permeation and the pump. I have had several issues with the Lian Li AIO.

    I have a strange issue where the pump does not start and my CPU quickly goes to 90c. I thought to myself I forgot something simple like, bad mounting, not plugging in the pump to the Motherboard, or even a low or bad duty cycle on the pump in BIOS. I checked everything and nothing was amiss. So I tried starting up the PC again and the previous issues were gone, pump was working, temps were normal even under stress testing. I restart after a firmware update to the AIO through the Lian Li L-connect software, and the pump does not start again. Scratching my head at this point, I decide to do a few reboots as a test. Four of the ten reboots I did on my PC would cause the pump to not start pumping. I would get as far as my desktop before I see that the CPU is at 90C and the fans are blaring at 100% as I log into windows. I thought to myself that I should see if it is related to the Lian Li software that has pump and fan controls causing the issue due to bugs by booting straight into BIOS. I get to BIOS and everything is normal. I reboot and again go back to BIOS, but this time while watching the CPU temps, I can see them climbing all the way to 90c and on the fan control page I can see that the pump is not responding to the CPU temps. Pump was at 0 RPM. So I am left with having to restart my PC after booting up if I notice my fans spinning up trying to compensate for no RPMs on the pump until the pump magically decides to start working.

    I went over my PC three times making sure everything is connected where it should be, updated BIOS, and still no resolution to this issue. I also have another issue with this AIO while it is working. The pump is, while "working," loud, very loud even. This issue of the pump being loud happened gradually over time. I figured I would go to Lian Li support to potentially get a software or firmware update to fix the 0 RPM pump issue on startup, so I kept it installed and would restart when it did not start pumping until it worked. I have had the AIO for three weeks now and the first week the pump was nearly silent with a small amount of whine at 4200 rpm so I kept it at 3600 rpm. In week two I noticed that it would have a slight grinding sound every once and a while. Now, and in the third week, the grinding sound is constant, but is lesser or greater at different RPM breakpoints. I can stand buggy, or janky software / firmware because that is fixable, but the pump was also seemingly failing as well. Because of these issues, I decided to return the AIO to amazon because it is still within the return window. I will be replacing it with an Arctic freezer 2. Wish me luck, I think I need it at this point...

    TLDR, 0 RPM pump at startup randomly, and when it does work after about a week the pump itself became louder, and louder...
