A range per fan, labelled (MAX)
Each fan gets a "Fan Noise Level" range in dB(A), running from its slowest rated speed to its fastest, beside matching ranges for RPM, airflow and pressure. This page ranks by the upper number, the one that belongs to the fan's highest rated RPM.
Most pages put "(MAX)" after the range, as in "22-32dB(A) (MAX)" on the CR-1000 EVO. The label marks the top figure and nothing more. When JONSBO means "at most", as on the CR-1200E, it prints "≤".
A two fan cooler gets one row per fan, labelled by size or as Fan 1 and Fan 2. Nowhere does JONSBO give a figure for both fans together, nor a test standard or microphone distance. Without those, cross-brand comparison is shaky, as our decibel ratings explainer sets out.
Which JONSBO single tower cooler lists the least noise?
The CR-1000 EVO, at 32 dB(A) and 1500 RPM, among single fan towers in stock on Amazon. The CA40 follows at 32.6 dB(A) and 1800 RPM.
| Model | Top figure | Fan | Top speed |
|---|
| CR-1000 EVO | 32 dB(A) | 120 mm | 1500 RPM |
| CA40 | 32.6 dB(A) | 120 mm | 1800 RPM |
| CR-1000MAX V2 | 33.2 dB(A) | 120 mm | 1800 RPM |
| CR-1400 EVO | 33.8 dB(A) | 92 mm | 2200 RPM |
| CB40 | 35.4 dB(A) | 120 mm | 1800 RPM |
The order roughly follows top speed.
The CR-1000 EVO's fan stops 300 RPM short of the CA40 and CR-1000MAX V2 fans and moves about 10 CFM less for it.
The CR-1000 EVO tops out at 32 dB(A)
From one 120 mm fan, the CR-1000 EVO lists 22 dB(A) at 600 RPM and 32 dB(A) at 1500 RPM.
Its Standard, Color and ARGB versions share one noise row, which makes the choice between them a matter of lighting. The CR-1000E lists the same 22 to 32 dB(A) but did not turn up on Amazon. Power is modest too. The fan draws 1.92W at most, about 60 percent of the CA40's 3.12W. The cooler stands 154 mm tall and weighs 554 g.
Which JONSBO twin tower is quietest?
The CA80, if you judge by the quieter fan in the box: its second fan lists 30.2 dB(A) at 1500 RPM. On the louder fan, the CA80 and CA90 tie at 32.6 dB(A).
| Model | Fans | Full speed figures |
|---|
| CA80 | Two 120 mm | 30.2 dB(A) at 1500 RPM and 32.6 at 1800 RPM |
| CA90 | 130 mm and 120 mm | 31.4 dB(A) from the 130 mm fan and 32.6 from the 120 mm, both at 1800 RPM |
| CC90 | 120 mm and 130 mm | 34.6 dB(A) from the 120 mm fan at 2050 RPM and 37.1 from the 130 mm at 1700 RPM |
Two more twin towers print lower pairs. The CR-3000V2 lists 29 and 31 dB(A) and the HX6280 30.4 and 32.1. No Amazon listing named either on November 8, and CR-3000 listings showed lead time only.
The CC90 has both the lowest floors and the highest peak
No other JONSBO cooler spans as wide a range. Its fans start at 700 RPM, 100 RPM below the CA90's, where they list 14.1 and 14.8 dB(A), and rise to 34.6 and 37.1 at full speed. The 130 mm fan is the odd one. It peaks at 1700 RPM, 350 RPM below the 120 mm fan, yet lists 2.5 dB(A) more, and JONSBO offers no explanation beyond the extra air it moves, 81 CFM against 77.81.
On a cooler this large the low end is the number to watch at a quiet desk. A 285W rating leaves room to run both fans slowly under most desktop loads, and slow is where the CC90 lists less than anything else JONSBO makes.
Is a 92 mm JONSBO tower louder than a 120 mm one?
At full speed, by JONSBO's figures, yes. The CR-1400 EVO's 92 mm fan lists 33.8 dB(A) at 2200 RPM, against 32 dB(A) for the 120 mm CR-1000 EVO at 1500 RPM.
Smaller fans need more RPM for less air. The CR-1400 EVO peaks at 38.2 CFM, while the CR-1000 EVO reaches 59.48 CFM 700 RPM slower, and the CR-1400E, CR-1400 V2 ARGB and CR-1400 DV2 print the same 22.3 to 33.8 dB(A) row as the EVO. One 92 mm model breaks the pattern. The CR-1300 EVO prints a single 28.2 dB(A)(MAX) at up to 2000 RPM, lower than any other current JONSBO tower at full speed. No Amazon listing under that name turned up.
Two low profile coolers, neither in stock
Both current low profile models are downflow coolers. The HP-400S lists 20.2 to 34 dB(A) at 900 to 2800 RPM, and the HP-600 18.3 to 37.2 at 800 to 1800 RPM. The HP-400S page gives its size as 103 by 92 by 36.7 mm, with a 90 mm by 15 mm fan and a 160W rating. The HP-600 is 66 mm tall, carries a 120 mm by 15 mm fan and is rated 210W, and its 37.2 dB(A) at full speed ties the highest figure in JONSBO's current cooler range.
Neither passed the Amazon check.
The HP-400S listing showed lead time, not stock, on November 8, 2026. No listing named the HP-600. The HX4170D, which JONSBO also sold, is end of life.
JONSBO's end-of-life list
Retired models go into an Air Cooling Radiator EOL Model list. On November 8, 2026 it included these.
| Family | Retired models |
|---|
| HX series | HX4170D, HX5230, HX6200D, HX6210, HX6240, HX6250 and HX7280 |
| HP and MX | HP400 and an older HP-400S page, plus the MX400 and MX600 |
| CR series | CR-3000 Standard, the first CR-1000MAX, the CR-1000 V2 PRO and the CR-1400 V2 Color |
The current HP-400S Black and White pages still sit in the Downflow Radiator category with the specs quoted above, so that model counts as current.
Current models that are hard to buy in the US
Several current towers print figures but had no in-stock Amazon listing under their model name on November 8, 2026: the CR-1000 V3 PRO, CR-3000E, CR-3000V2, HX6280, CR-2000 and the PISA A4 and A5.
For reference, the CR-2000 and CR-2100 list 29.5 dB(A) at 1500 RPM, the CR-3000E 34 at 1600 RPM, and the PISA A4 and A5 a single 36.8. The older CR-1000, CR-1000 GT and CR-1000 PRO list 37.2 at 1800 RPM. JONSBO's pages also give the CR-1300 and CR-1400 Color 30.5 dB(A), and the fixed speed CR-1200 30.5.
The CR-1200E prints only a ceiling, "≤ 26.5 dB(A) (MAX)", and is not ranked.
