Best Cooling Pad for ASUS ROG Flow Z13
The ROG Flow Z13 is a 13.4-inch gaming tablet, not a clamshell. ASUS lists the 2025 GZ302 at 30.0 × 20.4 × 1.30–1.49 cm and 1.20 kg, with Ryzen AI Max+ 395 / Radeon 8060S (or Max 390 / 8050S), dual 2nd Gen Arc Flow Fans, and a stainless-steel and copper vapor chamber that the brand says covers 55% more of the mainboard than the previous copper chamber. Intake is on the back. Exhaust is at the top. ASUS’s own cooling brief is that kickstand mode keeps a desk off those intakes. The 2026 first buy is the llano V10 — the sealed turbo stand that actually lists 13–17.3 inches and ships extra foam for a 13–14-inch chassis. Seat the vented back on that foam.

How We Picked These Pads
- The tablet: ASUS’s 2025 GZ302 spec is a 13.4-inch 2-in-1 at 30.0 × 20.4 × 1.30–1.49 cm and 1.20 kg, 70 Wh battery, 200 W barrel brick, two USB4 ports with DisplayPort and PD, one USB-A, HDMI 2.1, and a UHS-II microSD slot. Cooling is dual 2nd Gen Arc Flow Fans (84 + 42 blades), a stainless-steel and copper vapor chamber with 55% more mainboard coverage than the last copper chamber, an enlarged rear intake, a dust filter above the fan housing, and a small display airflow channel. Official full-load fan noise is under 45 dB. The Intelligent Cooling brief is the geometry: components sit behind the screen, so a deployed kickstand leaves the intakes in free air — the opposite of a Zephyrus G14, which drinks from the bottom. GZ301 (Intel + RTX) uses the same tablet layout. Some GZ302 SKUs list USB4 XG Mobile GC34 support; that is a dock on a USB4 port, not a reason to treat the Z13 like a 16-inch bottom-intake laptop.
- The pad type: IETS’s GT600 brief is explicit — 14.1–19.3″ chassis, cooling holes in the bottom, exhaust at the side. IETS says skip it when the bottom has no vents. The Z13 fails both gates: 13.4 inches, holes on the back. llano splits the line on purpose: V12 / V13 start at 15.6″; V10 is the 13–17.3″ stand with a 4.72-inch fan to 3,500 RPM, seal foam, and extra inserts for 13–14-inch machines. IETS’s own travel answer is the GT202UB: 85 × 80 × 35 mm, 280 g, 2,600–5,000 RPM vacuum clip, three silicone shrouds, rated for side vents 85–110 mm long and 20–38 mm tall. KLIM’s Ultimate is an 11–17.3″ open mesh with one 200 mm fan at 750 RPM ± 10% and four tilt stops — a stand, not a pressure box.
- What this page will not do: Clone the G14 / G16 Top 3 (GT600 V2 / V1 / GT500). Quote manufacturer 38–44 °C marketing drops as Z13 lab results. Recommend a magnetic phone cooler or Flydigi-style Peltier on the vented back. Invent first-person stress tests. An external pad does not replace Armoury Crate power modes or the 200 W brick for sustained Turbo.
Best Cooling Pad for ASUS ROG Flow Z13: Detailed Reviews
llano V10 View on Amazon
| Type | Sealed-chamber turbo stand |
|---|---|
| Laptop size (llano) | 13–17.3″, extra foam for 13–14″ |
| Fan | 4.72-inch, up to 3,500 RPM |
| Seal | 360° foam + dust filter |
| Extras | Physical buttons, 3 stand heights, USB-A / USB-C hub on hub SKUs |
| Z13 placement | Vented back on the foam; kickstand folded |
Why it fits the Flow Z13. This is the 13-inch sealed stand. llano’s V12 starts at 15.6 inches and belongs on the G16 page. The V10 listing starts at 13 inches and includes extra foam so a 13–14-inch chassis can close the gasket. The Z13 is 300 mm wide and 13.4 inches on the diagonal; that foam is the part that matches the tablet. Intake is on the back, so the tablet sits like a picture frame: vents on the fan, screen facing the room, kickstand folded. A wall adapter keeps the 70 Wh pack out of the cooler’s budget. USB-A on the Z13 stays free for a mouse if the hub SKU is the one in the box. Mid speed is the all-day setting; 3,500 RPM is a Turbo-mode setting, not a library setting.
Skip this if the tablet stays in kickstand mode on a hotel desk and the bag cannot take a 1.65 kg stand — that is the GT202UB. Skip it if the goal is only to keep the rear vents off a blanket; the KLIM does that job for less. Also skip any listing that is a V12 sold as a V10; the size band on the box has to start at 13 inches.
- Only sealed turbo in the Top 3 that officially lists 13 inches
- Extra 13–14″ foam matches a 300 mm tablet
- Own brick, so the 70 Wh pack is not running the fan
- Desk hardware — too big for a backpack next to the 200 W adapter
- 3,500 RPM is loud; use mid speed unless the session is Turbo
IETS GT202UB View on Amazon
| Type | USB vacuum clip (exhaust out) |
|---|---|
| Size / weight (IETS) | 85 × 80 × 35 mm · 280 g |
| Fan | 2,600–5,000 RPM, 13 speeds, auto-temp |
| Fit | 3 silicone shrouds; IETS: 85–110 × 20–38 mm vents |
| Power | USB, side-vent requirement on the product brief |
| Z13 placement | Top exhaust edge — not on the rear intake |
Why it fits the Flow Z13. IETS designed this clip to pull hot air out of a side or rear exhaust, not to pressurize a bottom deck. The Z13 dumps heat at the top. If the top slot fits a shroud, the GT202UB is the travel cooler that does not fight ASUS’s kickstand story: leave the stand open, leave the rear intakes in free air, clip the vacuum on the exhaust. IETS’s own Q&A is that this fan pushes air out while a GT500/GT600 pushes air in — on a Z13 there is no honest “in” pad in a backpack, so the clip is the portable half. Auto mode reads exhaust temp; manual mode has 13 steps. Power comes from the USB-A port. That is a few watts from a 70 Wh pack, not a second 36 W brick.
Skip this if the top vent is shorter than about 85 mm or blocked by a case. Skip it if the clip would sit on the rear intake — that is the wrong hole. A long desk session on the 200 W brick still wants the V10. Do not stack this on a GT600 and call it a Z13 solution; that stack is a G14 idea.
- Fits in the same pouch as the USB-C 100 W brick
- Works with kickstand mode instead of replacing it
- IETS lists ASUS among compatible brands; shrouds are in the box
- Official brief is side vents — confirm the top slot covers a shroud
- USB draw from the tablet, not a wall adapter
KLIM Ultimate RGB View on Amazon
| Type | Open metal-mesh stand |
|---|---|
| Laptop size (KLIM) | 11–17.3″ (manual also lists 10–17″) |
| Fan | One 200 mm fan, 750 RPM ± 10% |
| Noise (KLIM) | Up to 26 dB |
| Deck | 42.5 × 31.5 × 4.3 cm · ~980 g · 4 inclinations |
| Z13 placement | Kickstand feet on the grid; rear vents in free air |
Why it fits the Flow Z13. The G14 page tells readers to skip this pad, and that is correct for a bottom-intake Zephyrus. On a Z13 the job is often the opposite: do not seal a panel that has no intake holes, and do not let a sofa or a blanket cover the back. KLIM’s 11–17.3″ grid is wide enough for a 300 mm tablet, the 200 mm fan is quiet at 750 RPM, and four tilt stops give the kickstand a hard shelf. The mesh does not pressurize the rear vents. It keeps them legal. USB power is 5 V / 1.3 A on the manual — plug that into a charger hub when possible, not into the only USB-A during a 70 Wh session.
Skip this if the tablet will sit with the kickstand folded and the back needs a gasket — that is the V10. Skip it if the only goal is extracting top-edge heat in a backpack; the GT202UB is smaller. Also skip it as a “15 °C gaming pad.” It is a stand that respects ASUS’s intake story.
- Size band includes 13-inch tablets
- Quiet 750 RPM fan; four tilt stops for the kickstand
- Does not pretend to seal a rear-intake chassis
- Open mesh will not force air into the Arc Flow Fans
- USB-powered; no hub on the official spec sheet
If You Need Something Else
These two are not cheaper versions of the Top 3. One is the G14 pad this page used to recommend by mistake. One is a magnetic tablet brick that covers the intakes ASUS just enlarged.
IETS GT600 V2 View on Amazon
| IETS size band | 14.1–19.3″ |
|---|---|
| IETS requirement | Ventilation holes in the bottom |
| Fan | 5.5-inch, up to 2,800 RPM / 71.9 mmH2O |
| Right page | Zephyrus G14 / G15 / G16 |
The previous Z13 draft led with this stand after a fake forty-hour test. IETS’s own compatibility list is the reason it is not Overall here: 14-inch minimum and bottom vents. A 13.4-inch tablet with a vented back does not become a G14 because the logo says ROG. If the same desk also holds a G16, buy the GT600 for that laptop and keep the V10 for the Z13. llano V12 is the same miss — official band starts at 15.6 inches.
Skip this if the only machine is a Flow Z13. The G14 cooling-pad page is the GT600 V2 / V1 / GT500 stack.
Flydigi B6X / phone Peltier coolers View on Amazon
| Type | Magnetic / clip semiconductor cooler |
|---|---|
| Designed for | Phones and thin tablets with a solid back |
| Z13 problem | Sits on the vented rear ASUS enlarged |
The old draft treated a magnetic tablet cooler as a clever Z13 accessory. A Peltier brick wants a flat glass back. The Flow Z13’s back is the intake. Covering it undoes the vertical-orientation advantage ASUS published. Leave these on a phone.
Skip this on every GZ301 and GZ302. The V10 or the GT202UB is the external air; the kickstand is the built-in air.
Frequently Asked Questions
Why did this page drop the IETS GT600?
IETS writes the GT600 for 14.1–19.3″ laptops with holes in the bottom. The Flow Z13 is a 13.4-inch tablet with holes in the back. The G14 / G15 / G16 page is where that stand belongs.
Where does the llano V10 foam meet the Z13?
On the vented back, with the kickstand folded, so the gasket rings the rear intake. The screen faces the room. Extra 13–14″ inserts are there so a 300 mm tablet can close the seal. Do not park a closed kickstand on the foam and hope air finds a path around the hinge.
Is the 2023–2024 GZ301 a different cooling problem?
Same tablet geometry: rear intake, top exhaust, kickstand. The 2025 GZ302 changed the SoC to Ryzen AI Max and restated the vapor chamber; it did not move the vents to the bottom. The V10 / GT202UB / KLIM split still applies. The old Core i9 + RTX story is a GZ301 SKU, not a reason to buy a 19-inch stand.
What about XG Mobile on a 2025 Z13?
ASUS lists some GZ302 units with USB4 support for XG Mobile GC34 — a dock on a USB4 port, not the old proprietary edge connector. Extra GPU heat lives in the dock. The tablet still needs a clear rear intake. Keep the kickstand open or put the back on the V10; do not cover the vents with a magnetic cooler because an eGPU is attached.
Will an external pad void the ASUS warranty?
An external stand or clip does not. It is not a repaste and it is not a vapor-chamber swap. If the tablet is still under warranty and running hot, this is the reversible first step. Sustained Turbo still wants the 200 W barrel brick; USB-C PD is the travel charger.
Can these pads sit on a lap?
The V10 is a weighted turbo stand with its own adapter — desk only. The KLIM is a 980 g tray; possible on a lap, but the Z13 kickstand already wants a hard surface. The GT202UB is the one that travels. A sofa that closes the rear intake is the failure mode ASUS designed the kickstand to avoid.
Final Verdict
For a ROG Flow Z13 on a desk, buy the llano V10 and seat the vented back on the 13-inch foam. Traveling with the kickstand open? That is the IETS GT202UB on the top exhaust. Need a cheap stand that does not seal the wrong panel? KLIM Ultimate. Leave the GT600 and the V12 on the Zephyrus page, and leave magnetic phone coolers on phones.
