Customer Reviews
Customer Review: My liquid cooling kit for my ibuypower machine failed and machine keep shutting down after 60s. after monitoring the temperature i found the cpu temperature spike to beyond 90 and shut it down. Quickly look online for a replacement and found this thermalright assessin x120 for a good price. I have the SUS TUF X470-PLUS GAMING board. Removal of the water cooling kit was a bit harder but installing the thermalright assassin as easy and the machine was maintaing between 40 to 60 celcius without the fan noise is pretty low so it serve it job. has been on the setup for a few months and so far no issues yet.
Customer Review: Mister Twiggly is an ardent gamer, and his home-built gaming rig, while ancient, is capable. However, the stock cooler was getting a little noisy at times, so it was time for a replacement. Enter the Thermalright Assassin X120 Refined SE.Installation was fairly straightforward, though he had to pull out the motherboard to attach the backplate. From then on it was plain sailing.Testing showed that the CPU temperature is 10-15°C cooler at rest and 20-25°C cooler under load than the stock cooler, which he is holding in his right paw. Moreover, fan noise is barely noticeable – hardly surprising, since the fan is huge and runs far more slowly than its predecessor to cool that monster heatsink. This is music to Mister Twiggly’s fluffy but sensitive ears.A very good solution at a modest price.Mister Twiggly says “Hurrah for Thermalright!”, and gives this product his highest recommendation.

Customer Reviews
Customer Review: I recently installed the Peerless Assassin 120 SE ARGB in my build and I’m extremely pleased with the results. A few highlight points:With 6 heat-pipes and a dual-tower heatsink, this cooler handles high thermal loads surprisingly well for the price.It supports both Intel (LGA 115x/1200/1700) and AMD (AM4/AM5) sockets out of the box — easy to integrate into different systems.It is impressively quiet. According to the official spec the noise level tops out at ~25.6 dBA, which means minimal fan noise in daily use.The ARGB lighting is a nice bonus for anyone who cares about aesthetics, and it does not seem to compromise performance.My experience in use:Installation was straightforward (with the back-plate and mounting brackets included). After setup I noticed lower idle and load temperatures vs the stock cooler, and the system remained quiet even under sustained load. It also had good clearance around my RAM slots and GPU (always good to check fit in your case). In terms of value vs performance, this cooler really stands out.Minor note:You’ll want to check your case’s CPU cooler clearance, the heatsink is ~155mm tall.Also, if you’re doing extreme overclocking or very high-end CPUs at 300 W+ loads, this may not quite match the very top-tier 280/360mm liquid-coolers, but for most builds it gives excellent bang for the buck.Bottom line:If you’re looking for a high-performance air cooler that doesn’t break the bank, the Peerless Assassin 120 SE ARGB is hard to beat. Highly recommended.
Customer Review: Installed this cooler in my PC, and it’s honestly one of the best air coolers I’ve used. Temps dropped significantly compared to my old one, and it’s super quiet even under load. Installation was straightforward, and the ARGB lighting looks clean inside the case. Build quality feels premium, and the fans are smooth and silent. For its price, it’s an amazing value for keeping your CPU cool. It works perfectly as it is compatible with my R9 5900 XT. It has lasted around 2 years since I bought it and looks nice!

Customer Review: Great cooling temperature with overclock cpu ! Gets the job done
Customer Review: 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.

Customer Reviews
Customer Review: Happy surprise on this little cooler. I needed a cpu cooler for a tiny build I was doing and it had to be 135mm in height or less and the only one I could find was this at 130mm in height. Fits perfectly and the temperature on my 5950x is around 65°c or lower while using the computer for watching movies. Not sure how it would handle under gaming pressure or other workloads. Price was perfect too. Noise level is very soft. Works perfect and easily installed.
