Jonsbo TW3-240 (240mm AIO Liquid/Dual 120mm PWM Fans/Pure Copper Water Block/Legacy Socket Support) Review
If you're searching for the Jonsbo TW3, note that Jonsbo's TW3 line is actually an all-in-one liquid cooler, not an air cooler: the TW3-240 pairs a 240mm aluminum radiator with dual 120mm PWM fans and a pure-copper water block.
We'd point budget-minded builders on older platforms here, since the TW3-240's official socket list covers Intel LGA115X/1366/2011 and AMD's AM2 through AM3+/FM1/FM2+ era, but does not list AM4, AM5, or LGA1700/1851, so confirm your motherboard's socket before buying.
Thermal Performance and TDP Rating
Jonsbo rates the TW3-240 for 150W on Intel and 140W on AMD platforms, putting it in budget 240mm AIO territory, enough for mainstream non-overclocked CPUs but well behind flagship 240mm coolers.
Radiator and Pump Design
A 240mm aluminum radiator pairs with a pure-copper water block rated for 800-2300 RPM and under 25dBA, using minimized tubing and a sealed, maintenance-free loop rated for roughly 70,000 hours.
Fan Design and Noise
The two bundled 120mm PWM fans spin from 800 to 1500 RPM, delivering 21.6-50.4 CFM each at up to 25dBA, plain white LED fans rather than addressable RGB.
Socket Compatibility and Installation
The TW3-240's official support list is Intel LGA115X/1366/2011(-V3) and AMD AM2/AM2+/AM3/AM3+/FM1/FM2+, an older-platform lineup that notably excludes AM4, AM5, and LGA1700/1851, so this is best suited to older or secondhand builds.
Comparison to Alternatives
Against ARCTIC's Liquid Freezer III 240, covered elsewhere on this site, the Freezer III supports current AM5/LGA1700 sockets and delivers noticeably stronger thermals, making it the better pick for any modern build. The TW3-240's appeal is narrow: a cheap, basic 240mm loop for legacy-socket systems.

Expert Review

Expert rating6.2 / 10
A basic, inexpensive 240mm AIO that only makes sense for older, legacy-socket systems given its dated official platform support.
Best for
- Budget legacy-platform builds on AM2-AM3+/FM1/FM2+ or Intel LGA115X/1366/2011
- Builders who want a basic, maintenance-free 240mm AIO without RGB
- Simple installs where a pre-filled sealed loop is preferred over an air tower
Not for
- Modern AM4, AM5, or LGA1700/1851 builds, since these sockets are not on Jonsbo's official support list
- Builders wanting ARGB lighting
- High-TDP or overclocked CPUs beyond roughly 150W
