<summary>Question: Which cameras does the C072GBB3 cooling fan fit?</summary>
<div>

<summary>Question: Why does my camera need a cooling fan?</summary>
<div>
Answer: **Modern mirrorless cameras overheat during 4K / 6K / 8K video recording**, especially in warm weather or long-duration shoots. The sensor + processor generate heat; when it exceeds safe limits, the camera **shuts off video recording mid-shot** (a known frustration on Sony A7 IV, Canon R5, etc.). The cooling fan attaches to the back of the camera and actively dissipates heat, **extending continuous recording time by 2-3x** under hot conditions.

<summary>Question: How does it mount to the camera?</summary>
<div>
Answer: **Attaches to the camera's rear screen housing** via shape-fit + clip design. Each camera model has a slightly different fit profile, which is why Ulanzi tests model-by-model. The fan unit rests against the back panel where the camera body's heat naturally vents — cooling the source directly. Quick on/off without tools.

<summary>Question: How is it powered?</summary>
<div>
Answer: **USB-C power** — plug into the camera's USB-C port or a separate power bank. Low power draw means a small power bank runs the fan for a full shoot day. Some cameras can power the fan from their own USB-C while simultaneously charging the camera battery from the same USB-C port (depends on camera model).

<summary>Question: 1 PC ($39.95) vs 2 PCS ($79.90) — why buy two?</summary>
<div>
Answer: **Two-camera setup**: if you shoot multi-cam (main + B-cam) and both cameras overheat, the 2-pack gives you one per body. **Spare for travel**: keep one in the studio, one in the travel kit. **Two-year refresh**: fans are mechanical and eventually wear; a spare extends usable life.

<summary>Question: Black vs Silver — functional difference?</summary>
<div>
Answer: **None functionally** — same fan, same cooling power. Black matches most camera bodies (especially Sony / Canon). Silver matches Fuji silver tops / specific Sony A7C silver / Nikon Z series chrome trim. Pick on aesthetic.

<summary>Question: Will it work with my camera if it's not on the list?</summary>
<div>
Answer: The fan is **shape-fit per camera model**, so unsupported models may not mount securely. **However**: Ulanzi continuously tests new bodies. Email service@ulanzi.com with your camera model and they'll confirm compatibility or note when support is added. For brand-new releases (e.g., Canon R5 II / Sony A9 III), check before ordering.

<summary>Question: How does it compare to the Tilta Cooling System?</summary>
<div>
Answer: **Tilta Cooling System** ($90-130) — premium cinema build, multi-fan, supports more camera models, larger size. **Ulanzi C072GBB3** ($39.95) — single fan, narrower model list, half the price. Pick Tilta for cinema cage workflows / heavy professional video. Pick Ulanzi for indie / single-camera 4K vlog / interview overheating problems.
