Anova Precision Cooker 3.0 vs Greater Goods Sous Vide: measured accuracy against reputed quiet

Nobody has published a decibel reading for either of these circulators that you could hold up next to the other. The Greater Goods has a lab calling it extremely quiet, in words, by ear (E·08, E·09). The Anova Precision Cooker 3.0 has no verdict on sound from that lab at all, and one customer review on Anova's own page calls it noisier than its predecessor (E·10, E·11). What the lab did put a meter on points the other way: the Anova held its bath 0.06°F from setpoint, and the Greater Goods ran 0.82°F cool (E·06, E·07). So the choice is quiet by reputation against accurate by measurement.

We read both manufacturers' pages, TechGearLab's review of each machine, Anova's owner forum and the one sound benchmark we could find for circulators. We didn't run a bath or hold a meter ourselves. Each machine has its own write-up: the Anova Precision Cooker 3.0 review and the Greater Goods review. This piece sets them side by side on the one question the search results keep asking.

The short table

Values from Anova's and Greater Goods' pages and TechGearLab's reviews (E·01, E·03, E·04, E·05, E·06, E·07, E·08, E·09, E·10, E·19). No column carries a winner flag: the measured rows favor the Anova, the one row about sound favors the Greater Goods, and that row is an impression. Dollar figures are left out on purpose, since the Anova's price moved between our visits (E·02).

Sound: what exists, and what it can't carry

Greater Goods says the unit runs silently on a brushless motor (E·03). TechGearLab agrees in print twice: in its review of the machine, the Greater Goods is among the quietest options in the test suite, thanks to that motor (E·09), and its roundup calls it extremely quiet (E·08). That is the whole case for the Greater Goods on sound. It comes from one lab, by ear. Noise is not one of the four things that lab scores, and neither page gives a decibel figure (E·08, E·09). It places the Greater Goods among the quietest in that suite. It doesn't say by how much, or whether you could hear the difference across a kitchen.

The Anova's file is thinner. The lab's roundup says the Nano 3.0 was among the loudest circulators in operation, and names the 3.0's timer, not its sound, as its only issue with it (E·10). So the lab hears loud machines when they are loud, and flagged nothing on the 3.0. A lab staying quiet isn't a measurement of quiet, though, and the other voice on record is a single customer on Anova's page: 'noisier than its predecessor', which compares the 3.0 to an older Anova and not to the Greater Goods (E·11).

Decibel numbers from owners are worse than none. In August 2026 an owner posted that a 3.0 made a very loud sound and gave a reading of 70 dB while it warmed up. A day later the same owner traced the noise to a battery backup nearby that had alarmed on the cooker's warm-up current, and concluded the Anova was fine (E·12). The reading was accurate about the room and wrong about the cooker. A figure only means something next to another taken at the same distance, with the same background noise, the same water level and the same point in the heating cycle.

The one table of circulator sound levels we found, from the site Amazing Food Made Easy, shows the problem from the other side. It used a RadioShack meter in a room it put at about 50 dB, and its authors say it lacks the rigor for a scientific journal (E·13). Neither of our two machines appears in its list (E·13). The benchmark is old and measured older machines, not the 3.0 and not the Greater Goods. A circulator reading a few decibels over a 50 dB room is hard to tell from the room.

Put together: the Greater Goods has the better-attested claim to quiet, the size of the gap is unknown, and it may be too small to hear. If your pot sits in the room where you sleep or work, that is a reason to lean Greater Goods. If you can close a door, the evidence doesn't give you a reason to pay for the difference.

Accuracy: the measured gap

This is the row where a meter was involved on both machines. TechGearLab logged the Anova's bath at an average of 0.06°F from setpoint (E·06). It logged the Greater Goods averaging 0.82°F cooler than the claimed temperature (E·07).

Measured data

For a 135°F steak, 0.82°F is a shrug. For a 145°F custard or fish held near 122°F it can be the difference between the texture you planned and the one you served, and a cool bath errs toward undercooked. The Greater Goods carries an on-device calibration feature meant for exactly this: check the water once against a thermometer you trust and dial in the correction (E·03, E·07). How far that adjustment reaches is not published (E·07). The trade, then, is a reference thermometer and one calibration session against a bath that needs neither.

Both figures describe single units on one bench, and the Greater Goods page carries a 2022 byline (E·05, E·09).

Heat-up, circulation and the clamp

The Anova heated 9.5 quarts of 50-degree tap water to 147 degrees in 36 minutes (E·04). The Greater Goods took 39 minutes (E·05). The two ran on water two degrees apart, which accounts for a sliver of the gap (E·04, E·05). Three minutes of preheat is real if you fill a tub from the cold tap every weekend and invisible if you don't.

Clamps differ in what we can say about them. The Anova has a twist-style clamp with a 1.4-inch gap (E·15). The lab calls the Greater Goods clamp sturdy and says it fits a variety of pots and Tupperware, but gives no gap in inches (E·17). Each has a timer chore too: the Anova's timer starts by itself when the bath reaches setpoint, with no setting in the app to switch that off (E·16), and the Greater Goods' dial makes you spin through every minute to reach an hour (E·17). The lab praises that dial otherwise, saying it spins smoothly (E·17).

Controls, apps and what can go wrong

Both machines put the cooking controls on the device. The Anova adds WiFi and an app on top (E·01), and Anova states that its devices work without a subscription and that every Anova cooker except the Mini has manual controls (E·14). Anova's current plan table lists remote temperature and time control, progress monitoring and remote start/stop as free, and puts the 1,000-plus recipe library, cook history and notifications behind Premium (E·14). Our Anova subscription guide walks the history. The Greater Goods goes further: it has no app and needs no WiFi (E·19). The upside is that nothing can be switched off remotely. The cost is that nothing can be started, watched or alerted remotely, so a long cook that runs low on water is your problem unless you checked the lid (E·19).

On durability the record is thin for both. The Anova comes with a 2-year warranty, an IPX7 rating and a 65 mm low-water shutoff (E·01). One owner reported a 3.0 dying during preheat about two years and five months after purchase, a few months past the warranty (E·18). The Greater Goods warranty activates on registration and its length is not published (E·03). We found no failure thread for it, but the brand sells far fewer units, so that silence is weak evidence either way (E·18).

On price, the Greater Goods' direct listing in August came to less than half of Anova's regular price (E·02, E·03). Check both stores before deciding, because Anova's price changed between our two visits (E·02).

What would change this

• A decibel reading for each machine from the same source, at one stated distance, with background noise and water level documented, and a gap wider than the meter's tolerance. That would turn the sound row from impression into a number (E·08, E·09, E·13).
• Any lab remark ranking the 3.0 against the Greater Goods on sound. Until then the lab's only comparison is within its own suite (E·09, E·10).
• Multi-unit accuracy data on the Greater Goods. If most units run closer than 0.82°F, the Anova's lead in the table shrinks (E·07).
• A published warranty length from Greater Goods, in either direction (E·03).
• A second Anova 3.0 failure report from around the two-year-five-month mark. One is an anecdote; a cluster is a pattern (E·18).

Both accuracy figures describe one unit each, and the Greater Goods store page returned an error on every attempt on October 20, 2026, so its price, warranty and brushless-motor entries rest on our August capture (E·03). The Inkbird route sits in our Inkbird vs Anova 3.0 comparison, and the criteria that separate circulators beyond noise are in the circulator guide.
