There is no defensible universal winner between the Accelero S1 Rev. 2 with Turbo Module and an unspecified Accelero Twin Turbo: “Twin Turbo” covers multiple revisions, and the available figures come from different graphics cards rather than a controlled head-to-head test. Identify the Twin Turbo revision and check fit against your exact GPU before choosing. The documented Twin Turbo III specifications below apply only to that revision.
Which coolers are being compared?
Accelero S1 Rev. 2 with Turbo Module
The Accelero S1 Rev. 2 is a passive heatsink; the optional Turbo Module adds two 80 mm fans. Its data sheet describes a heatsink measuring 138 × 215 × 33 mm, weighing 268 g, with four 6 mm heatpipes. The archived module specification lists each fan at 1500 RPM and gives 42 CFM airflow and 35 g for the module. ARCTIC/Arctic Cooling’s S1 Rev. 2 data sheet and its Accelero S and Turbo Module specification sheet document these details.
Accelero Twin Turbo revisions
The name is not specific enough to identify one model: ARCTIC’s GPU cooler support and product selector lists both Twin Turbo II and Twin Turbo III. The detailed specifications available here are for Twin Turbo III only. They should not be treated as specifications for the original Twin Turbo or Twin Turbo II.
What do the published temperature and noise figures show?
Archived manufacturer product material reports results for two separate test setups. They suggest how each cooler performed in its own listed test, but do not establish which is better on the same GPU under the same conditions.

| Setup in the product sheet | Reported result | What the figures apply to |
|---|---|---|
| Accelero S1 Rev. 2 with Turbo Module | 48°C at 1500 RPM; 0.15 Sone | GeForce 9600 GT; the sheet states 24°C ambient. ARCTIC/Arctic Cooling’s archived product sheet; publication year not established in the retrieved extract. |
| Stock cooler in the S1 sheet | 79°C at 2700 RPM; 1.2 Sone | The same listed GeForce 9600 GT test and stated 24°C ambient; ARCTIC/Arctic Cooling’s archived product sheet, publication year not established in the retrieved extract. |
| Accelero Twin Turbo III | 56°C at 2000 RPM; 0.3 Sone | GTX 770; ARCTIC’s Twin Turbo III sheet, publication year not established in the retrieved extract. |
| Stock cooler in the Twin Turbo III sheet | 70°C at 4000 RPM; 3.7 Sone | The sheet’s GTX 770 comparison; ARCTIC’s Twin Turbo III sheet, publication year not established in the retrieved extract. |
The S1 results are from a GeForce 9600 GT, while the Twin Turbo III figures are from a GTX 770. The cards, coolers, and listed fan speeds differ, so subtracting one set of temperatures from the other—or using the results to rank the coolers—is not a valid head-to-head comparison. The Twin Turbo III figures are also not evidence about an unspecified Twin Turbo revision. The relevant documents are the S1 and Turbo Module specification sheet and Twin Turbo III specifications.
What fit and clearance checks matter?
Confirm the exact cooler revision
Check the label, packaging, or seller’s documentation to determine whether the Twin Turbo is the original model, Twin Turbo II, or Twin Turbo III. Revision matters because a specification or compatibility list for Twin Turbo III cannot confirm fit for the other versions.
Rank #2
- COMPATIBILITY: The ARCTIC Alpine 17 is a compact CPU cooler exclusively for the Intel sockets LGA1851 and LGA1700
- COMPACT: With an installation height of only 68.2 mm, the Alpine 17 is compatible with most all-in-one systems and SFF cases (Mini-ITX, µATX, etc.)
- EFFICIENT COOLING: The 92 mm fan can be controlled via PWM and provides the necessary flexibility and balanced cooling performance with its wide speed range
- GOOD HEAT DISTRIBUTION: The Y-shaped fin design ensures optimal heat distribution in the heatsink. Heat dissipation profits significantly from its large surface area and high airflow rate
- SIMPLE INSTALLATION: Pre-applied MX thermal paste and pre-mounted push pins allow effortless installation, even for beginners
Match the cooler to the exact graphics-card layout
Do not rely on a GPU family name alone. Board partners can use different PCB dimensions and component layouts for cards with the same GPU. Verify that the cooler’s mounting hardware, contact points, and coverage suit the precise card, including its memory and power-delivery components. The retrieved S1 sheets have differing compatibility lists, making a model-and-layout check essential.
For Twin Turbo III specifically, ARCTIC’s sheet says compatibility is for standard-size PCBs 98 mm wide, warns that low-profile and extended-PCB examples are excluded, and bases its list on reference layouts. It also flags possible interference with the first expansion slot. These are Twin Turbo III warnings, not established specifications for every Twin Turbo revision.

Check case and slot space
Compare the cooler’s full dimensions with the card, adjacent expansion slots, and nearby case components. For Twin Turbo III, the listed overall size is 247 × 140 × 89 mm. The S1 Rev. 2 heatsink is listed as 138 × 215 × 33 mm, but adding its Turbo Module changes the installed configuration; confirm the total clearance for the actual parts rather than treating the heatsink dimensions as the complete assembly.
How should you choose?
- Choose based on confirmed compatibility first. A cooler that does not mount correctly or clear nearby components is not a useful upgrade, regardless of its published temperature.
- Compare noise and cooling only with comparable evidence. Look for testing on the same card, under the same ambient conditions and methodology, with fan speed and noise measured consistently. The available manufacturer figures do not meet that standard across these two configurations.
- Account for airflow and the rest of the build. The S1 depends on passive cooling unless fitted with its Turbo Module; system airflow therefore matters. Fan placement, case ventilation, and clearance can affect the practical outcome of either cooler.
- Inspect legacy hardware before buying used. Check that the correct mounting pieces and any included fans are present and in working condition. The available sources do not establish current availability, listing condition, or the contents of a particular used listing.
What the specifications establish—and what they do not
The S1 Rev. 2 with Turbo Module is documented as a passive heatsink supplemented by two 80 mm fans, with historical product-sheet results for a GeForce 9600 GT. Twin Turbo III has its own documented design and GTX 770 results, but those figures cannot settle a comparison with the S1 or identify the performance of an unspecified Twin Turbo revision. A reliable choice therefore depends on the exact cooler revision, the exact GPU PCB and available clearance, and comparable testing for the card you intend to use.
