Complete the kryozon s9 first setup water loop before your first game. The phone-mounted cooling end has no fan. The pump needs a water container and compatible power. The printed S9 operating instructions say to fully immerse the pump before connecting power, mount the cooling head, then press the inline controller to start cooling. Lay out the components where you can see them. No hose-connector procedure is required.

Key Takeaways
- First installation starts with component placement before power or controller input.
- Pump operation requires complete water submersion before the first game.
- Rated 30 W operation requires compatible Type-C power at 12 V / 2.5 A or higher.
- Phone mounting needs a hands-on fit check with the actual case and gaming grip.
Identify the S9 parts and assemble the water loop: layout comes before power
Set the KryoZon S9 Water Cooling Phone Cooler beside the phone and sort the parts by function. The cooling head mounts to the phone, the illustrated pump sits in a water container, tubing carries the water, and the inline controller operates the unit after mounting. The printed operating guide shows the pump, head and controller sequence, while the S9 product FAQ specifies a 1.2 m tube. Route the tube across the desk without obstruction before opening your game.
The S9 operating steps cover the supplied pump, cooling head and controller. They do not show a PC-style loop assembled from loose fittings. If your kit includes an unidentified loose joint, check its included instructions or ask KryoZon support where it belongs.
Put the phone in its normal playing position, then place the pump container where the 1.2 m tube reaches without pulling on the mounted head. Position the inline control within reach without moving the container. Reservoir size and flow rate are not part of the printed first-start sequence.
Keep the kit manual with the S9 components. If you need to contact support, compare the components with the illustrated arrangement rather than using a creator’s desk layout as an inventory checklist.
| S9 setup detail | Published specification or instruction | What to check at your desk |
|---|---|---|
| Tube | 1.2 m | Route without tugging on the phone mount |
| Cooling end | 75 g | Check that the mounted phone feels secure |
| Power for rated operation | Type-C, 12 V / 2.5 A or higher | Read the source’s output rating |
| Phone width | Up to 92 mm | Check the actual phone and case fit |
Methodology: Specifications are from the KryoZon S9 official product FAQ; the desk checks are installation advice, not measured test results.
A submerged pump and compatible 12 V power precede cooling
Fill a large-capacity container with room-temperature water and fully submerge the illustrated pump before operation. The printed S9 operating guide prohibits running the pump dry. Place the container where movement at the gaming desk will not pull the pump from the water. After routing the tube, confirm that the pump remains submerged.
Read the output label on the proposed Type-C power source before connecting the S9. According to the official S9 FAQ, rated 30 W operation requires 12 V / 2.5 A or higher; a basic 5 V USB port is insufficient. The printed guide separately recommends a compatible 12 V / 3 A fast-charging source. The FAQ gives 12 V / 2.5 A as the requirement for rated operation, while the guide recommends 12 V / 3 A.
A connector that fits does not confirm the output rating. If a desk hub supplies only a basic 5 V USB connection, use a source whose listed output meets the S9 FAQ’s 12 V requirement. Route the power lead away from the container opening, controller and your hands’ path during play.
The controller’s temperature display does not measure pump flow. The S9 FAQ lists a real-time temperature display but does not identify it as a pump-flow measurement. Use the pump placement specified in the printed instructions.
Mount the cooling head and check the first start: contact comes before controls
The S9 offers magnetic attachment and a clip, and the official product FAQ lists support for phones up to 92 mm wide. Choose the attachment for your phone or compatible magnetic case, then check that it remains stable in your normal playing position. The published width is a phone-fit specification, not a promise about every case profile, camera bump or gaming grip.

Inspect the contact area before starting a match. A raised case section can leave the mounted head against the case rather than the intended surface. Check the fit on your phone; do not cut or modify the case. If you use a telescopic controller, fit the phone, controller and S9 head together while the system is off. A secure phone mount does not confirm clearance for your thumbs and the controller shell.
Press the inline controller button to start cooling after the pump is submerged, compatible power is connected and the cooling head is secured to the phone. That order comes from the printed S9 operating instructions. Before launching the first game, make sure you can reach the controls and turn the screen without pulling the tube or shifting the water container.
To stop the unit, the printed operating guide specifies a 2-second long-press on the controller button. Find the control before starting a match. The S9 FAQ also lists an overheat alert and automatic shutoff.
The S9’s three modes serve different first-session workloads

The official S9 FAQ lists High, Low and AI modes. Choose one labeled mode before you begin, and note the setting used for each game or recording.
For gaming, record the game name, selected mode, phone, case and mount arrangement. Keep that arrangement unchanged while judging how the setup feels in your hands. Do not read the controller display as an FPS meter or phone-processor temperature. The product FAQ describes it as a real-time temperature display and does not define either measurement.
For voice chat or recording, make a short microphone test with the pump in its planned desk position. The S9 cooling end is fanless, and its pump has a manufacturer rating below 30 dB, according to the official FAQ. Listen for audible pump noise in the position you will use before going live.
The S9’s 1/4-inch brass thread fits a compatible streaming stand or tripod, according to the product FAQ. Check that the complete phone-and-head arrangement is stable on the support before connecting cables or recording. For rated 30 W operation, the product FAQ specifies a Type-C source rated 12 V / 2.5 A or higher.
A desk-side fit check prevents first-game surprises
Check the contact area and controller clearance together
Check the S9 head’s contact with your phone or case, then hold the phone in your normal playing position. Confirm that the tube does not pull on the mount and that a telescopic controller, if used, still leaves room for the cooling head. The FAQ’s up-to-92 mm width specification does not confirm fit with a specific case, grip or controller setup (S9 product FAQ).
Keep the display and safeguards in their documented roles
The S9 controller’s temperature display does not verify pump flow or game frame rate. The listed overheat alert and automatic shutoff are S9 features, while complete pump submersion is an operating instruction. Check the water container and pump directly before pressing the button (S9 product FAQ; printed operating guide).
Place the phone-mounted head on one side of the desk and the pump’s room-temperature water container on the other, with both visible. For stand-mounted recording, leave enough tube slack for the phone’s final position. Keep the printed S9 operating guide at hand during startup.

Frequently Asked Questions
Do I need to connect individual hoses for the KryoZon S9?
The printed S9 operating steps show no port-to-port hose connection. Arrange the kit parts as shown. Contact support if a connection is loose or cannot be identified.
What power source does the KryoZon S9 need?
The S9 FAQ specifies a Type-C source rated 12 V / 2.5 A or higher for rated 30 W operation. A basic 5 V USB port does not provide enough power.
Can I start the S9 before putting its pump in water?
No. The printed operating guide requires the pump to be completely submerged and prohibits dry operation. First, fill a large-capacity container with room-temperature water.
How do I turn off the S9 after my first game?
According to the printed S9 operating guide, long-press the inline controller button for 2 seconds to turn the product off. Keep the controller within reach while gaming.
