Don't need anything more!
All Thermalright coolers seem to be the same, brilliant bang for your buck! The white and the ARGB looks fab and is easily controllable with its universal 3 pin ARGB connector. Performance level is good and will cool any medium wattage CPU with ease. On its PWM setting its very quiet and the whole cooler is extremely easy to install with its included instructions. 5 stars!

Excellent product at excellent price
Was getting around 40°c idle using stock intel cooler and switched to the thermalright Assassin X 120 SE and got 25°c idle! It super quiet at 500 rpm on idle. Under load at 90% CPU utilisation the fan was only at 1100 rpm on 60-ish °c. Recommend especially for the price huge difference from stock cooler and easy to install as well!

Worth the money as it dropped my CPU temps drastically.
It got my CPU temps down drastically, with my Stock cooler it was idling at 50C+ with my I5-14400f when i swapped to this it was idling in the 25C range. A simple game like Command and Conquer Kane's wrath (v old game) had my stock cooler running at 100% with temps in the 90C range now they are in the 50C range. At 148mm high its a tight fit (3 to 5mm spare) in my Micro ATX case.

Great value, classic Thermalright performance.
Massive difference over the stock cooler. Running a 5600 overclocked (4.8GHz under load), temps rarely get over 60c core and 70c for the package temp, and that's with all fans (8 of them including this one) set to standard rather than turbo or full speed. If I do set fan speed to turbo, temps come down to 50c and 60c respectively under load, but that's too noisy for my liking. One thing to note is this thing is a big, make sure you check your case is big enough before buying. I did have my GPU set horizontally, but sadly it won't fit with this cooler, so I've had to set it back to standard mount, which is a shame. ARGB works well, unfortunately, the cable only has a female connection, with no male output to continue the daisy-chain, managed to get around that issue with a splitter cable brought through Amazon, would have been nice if a passthrough was provided though. All-in-all for the price of £15, this item is tremendous value with all of the classic Thermalright performance.

Great cooler for 65 watt TDP
Using it on a TDP 65 watt Intel i5 11400F. Cooling At idle temps are around 28c at load around 50c. Its really quiet. Thermal paste was fine and had plenty. Was easy to install.

Amazing performance for price
Cheap isn’t always cheerful especially with PC parts so if you’re skeptical like me on if this cooler is upto the job or not - It is! *Updates at the bottom* After reading/watching a myriad of reviews online I took the plunge not expecting much from a single fan air cooler after having my AiO for three years. I needed something robust yet cheap if possible to cool my 5700X. Packaging does the job, all protected by that typical foam packaging. Heatsink and fan, little baggies labelled with each Mobo type for the connectors. Thermal paste included. Firstly, installation is smooth and simple, instructions are typically basic but the pictures do a good job of explaining what to do for Intel and AMD. Be aware you may want to connect the fans pin connector before installing the heatsink but it’s a pain free process that took me all of about twenty minutes. The thing I like about this cooler is the ability to position your fan slightly higher thanks to the metal clips that grip the heatsink, this allows you to get some critical space between ram. Performance wise this things an absolute monster. I’m currently in the process of undervolting my 5700x and at my current settings this thing didn’t budge past 56C on prime95 and that’s without an exhaust fan currently in my PC. My AIO even when it worked would peak 58/60C dependant on ambient temps! So using the thermal paste included I loaded up CSGO first, then Modern Warfare 2. Now I didn’t play for a prolonged period so I will update this review as time goes on, but in my brief hour testing session my CPU capped out at 60C max. No curve adjustment, fans are barely audible over sound from monitor, a faint ‘hum’ tops. Again this is without an exhaust fan so currently my PC is circling warm air. Absolutely amazed with the results and for the price I cannot fault this product one bit. Don’t hesitate. Update as of Feb 21st 2023 - I haven’t gotten around to undervolting any further at present but am extremely happy to update that even with the likes of Red Dead Redemption or World of Warcraft Dragonflight (1080&1440p) this fan won’t let my 5700x budge over 64 degrees even with prolonged use!

Lüfter manchmal sehr hörbar, aber an sich ein solider Kühlkörper.
