I don’t have exact bench-marking numbers, but I can say this JONSBO CA90 has cooled my Ryzen 7 3800XT more efficiently than my old 120mm AIO ever did. That isn’t super surprising since this thing has way more fin surface area, but the real-world difference has been dramatic. With my AIO I was regularly seeing around 80C under load and about 50C at idle. After switching to the CA90, I haven’t seen my CPU go over 60C under load and it idles around 40C, which is a huge improvement in both directions. Install was simple and the mounting process was straightforward for a dual-tower style cooler. I had no issues installing it in my smaller-form-factor Mini-ITX case. One thing worth mentioning is I was a little surprised to see the heat sink was slightly bent when I first took it out of the box. Heat pipes are pretty flexible though, and I was able to gently bend it back into place without any issues. Once mounted, everything sat correctly and it’s been performing perfectly since. Build quality feels solid and the size is definitely substantial, so measure your case and RAM clearance before you buy, but once it’s in there it feels like a serious cooler. I have RGB Trident Z DDR4 RAM in mine and it just barely clears it. I did swap the stock fans for Noctua fans, mainly because I already had them in this build, so my exact noise and airflow results will vary from a fully stock setup. Even so, the heat-sink itself is clearly doing a lot of the work here and the performance has been excellent. Aesthetics are also a big win. I love the RGB on this because it’s super tasteful. It’s not a giant glowing nightclub block, it’s just a clean little streak of light that crosses the edges and it looks premium in a build. Overall this cooler looks insanely clean, performs way better than my old 120mm AIO, and it’s an easy 5/5 for me. For how well this cooler looks and performs, the current asking price of $47.99 is more than fair.

I grabbed this cooler for a new build I've been working on, as I'm familiar with Jonsbo's chassis offerings and have also tried one of their coolers previously, with great success. The cooler arrived in a smallish box packed with parts used to support various socket types, as one would expect. The instructions are clear and easy to understand, describing all the details one requires to complete the assembly. It also contains a tube of thermal compound for the CPU to heatsink thermal transfer. Assembly was as easy as I'm accustomed to from building many coolers over the years. However, it's not tough, so if this is your first, you'll be fine. Just take your time. In my case, this went on a socket 1200 board, and the fit was perfect. In use, the fan speed remained low and quiet even under load, as the heatsink is very efficient with the six thermal pipes. At 270 degrees of thermal dispersion, most users will be just fine and experience smooth, quiet cooling. installed and with the RGB LEDs enabled, it's a great-looking cooler and shows off the unique style that Jonsbo is bringing to the PC building arena. Even better, Jonsbo is showing off its ability to offer great performance and good looks at a reasonable price. I'll continue to check out Jobnbo parts as I'm impressed with the few that I have already tried.

This is a fantastic high TDP air cooler from Jonsbo. I would say high end, but its price is no where near high end coolers. I really like what Jonsbo has been doing lately and have been building custom computers with quite a few of their products. This cooler says that It has a cooling TDP of 270 watts. This is inline with other coolers this size from Thermalright and more expensive brands. I have with in the last two years, transitioned away from AIO CPU coolers in my builds, especially for clients. My go to cooler is the Thermalright Phantom Spirit, and I have found that it preforms just as well as the AIO liquid coolers even with a high end PCU. This Jonsbo CA90 is cooling even better than the Thermalrights I have used. I have this running on a Ryzen 7950x3d @PBO -20 all core in a smaller Jonsbo D41 case. Keep in mind that this case has excellent air flow for a small case, and my office temperatures are in the low 60s. This thing rocks. I ran Cinebench for 30 minutes, and I never hit 80c. Just under that at 79c was the highest that my CPU go, and the Cinebench score beat that of my 360 AIO that was just in there. The cooler is also quiet, and looks way nicer that my Phantom Spirits do. The RGB is simple and nice, and the fans seem like they are very nice quality. The only slight issue that I have is that the fan and rgb cables are short to keep down clutter, and that is nice, but if you are installing this in a completed build, it is tight and I found it difficult to get the cables connected. If you are installing this before putting the motherboard in the case, then it is a non issue. Over all this is an amazing cooler, really 10/10, and is now on my shortlist for CPU coolers in my custom builds.

Early 2026 is a tough time for the DIY PC builder - prices on components are spiking, and putting together anything more than a basic machine has become very expensive. This has led to a rise in resurrecting older hardware and repurposing it for today. Even CPU's from several generations ago, while not absolutely top performers today, can be pushed into duty as reasonable gaming or homelab machines. And during this process, some improvements can bring it closer to modern specs too, such as improved cooling. This tower cooler is a good example - paired with yesterday's flagship CPU's (or today's if you can afford it) it manages heat very well, if you have the case to support it. In addition to a large 270W TDP handling capacity, it also conducts heat quickly away from the CPU giving good thermal recovery results. Compared against my "gold standard" Thermalright "peerless" tower cooler of similar construction, the JONSBO CA90 kept my Core Ulta 9 285K system temperatures under control well, with idle temperatures comparable to the TR cooler, stress temperatures within margin-of-error differences, and recovery curves very similar. Once fan curves are adjusted, I rarely saw the fan's ramp higher than 35% except under very high load. At idle and at 1M distance I could not hear the fans, and while not silent at higher RPMs the noise wasn't objectionable, giving a mid-tone burring noise and no high pitched noise. RGB effects are subjective, so I'll only say these aren't completely over-the-top and, not being much of an RGB person myself, I didn't find them objectionable and they would probably fit tastefully into a gaming oriented machine. What could still be better: RAM clearance - although JONSBO touts this as a feature, I feel it could still be better. Technically you don't need to remove the fan to get to the RAM DIMMs, but practically you still should as the fit can be tight depending on your particular board.
