電視盒子發熱，正常定唔正常？/ Is a Warm TV Box Normal?
先講結論：電視盒子運作時發熱係完全正常嘅。內部處理器同影像解碼晶片工作時必然產生熱量，尤其係播放 4K 或者長時間串流嘅時候。機身摸落溫暖，唔代表有問題。
First, the short answer: it is completely normal for a TV box to feel warm during use. The processor and video decoding chip generate heat by design, especially during 4K playback or long streaming sessions. A warm casing is not by itself a sign of a fault.
真正需要留意嘅係「過熱」——即係熱到出現以下情況：
What genuinely warrants attention is overheating, which shows up as:
- 播放途中畫面突然停頓、自動重啟 / Playback freezing or the device spontaneously rebooting
- 系統反應明顯變慢、遙控延遲 / Noticeably sluggish response and remote lag
- 機身燙手（唔止溫暖）/ The casing hot to the touch, not merely warm
- WiFi 連線變得唔穩定 / WiFi connection becoming unstable
常見過熱成因 / Common Causes of Overheating
1. 擺放位置唔通風 / Poor Ventilation
最常見嘅成因。好多用家將盒子塞入電視櫃嘅封閉隔層，或者疊喺其他電器（例如機頂盒、遊戲機、擴音機）上面。呢啲位置熱空氣散唔走，溫度會不斷累積。
By far the most common cause. Many users tuck the box inside a closed TV cabinet compartment, or stack it on top of other electronics such as a set-top box, games console or amplifier. Hot air cannot escape and temperature builds steadily.
2. 散熱孔被阻塞 / Blocked Vents
機身側面同底部嘅散熱孔積聚灰塵，或者被布、雜誌、擺設遮住，會直接影響散熱效率。
Dust accumulating in the side and base vents — or the vents being covered by cloth, magazines or ornaments — directly reduces cooling efficiency.
3. 環境溫度過高 / High Ambient Temperature
香港夏天室溫可以去到三十幾度，如果房間冇開冷氣又長時間播放，盒子本身嘅散熱空間就會被壓縮。
In a Hong Kong summer, room temperature can exceed 30°C. Streaming for hours in an unconditioned room leaves the device far less thermal headroom.
4. 長時間高負載運作 / Sustained Heavy Load
連續播放 4K 內容、長時間掛機、或者同時運行多個應用程式，都會令處理器持續高負載，發熱量自然增加。
Continuous 4K playback, leaving the device running for very long periods, or running many apps at once keeps the processor under sustained load and raises heat output.
六個實際可行嘅改善方法 / Six Practical Fixes
-
留出四周空間：盒子四邊同上方最少預留 5–10 厘米空隙，唔好貼牆或者塞入封閉櫃。
Leave clearance — at least 5–10cm around and above the device. Avoid pressing it against a wall or sealing it inside a cabinet. -
唔好疊放電器：唔好將盒子放喺其他發熱電器上面或者下面。
Don't stack electronics — keep the box off (and out from under) other heat-producing devices. -
定期清潔散熱孔：每幾個月用軟毛刷或者壓縮空氣清走灰塵。
Clean vents periodically with a soft brush or compressed air every few months. -
避免陽光直射：唔好將盒子擺喺窗邊被太陽曬到嘅位置。
Keep it out of direct sunlight. -
長時間使用後畀佢休息：連續使用好多個鐘之後，短暫關機十幾分鐘有助降溫。
After many hours of continuous use, powering off for 10–15 minutes helps it cool down. -
考慮加散熱底座：如果環境真係焗，可以用被動散熱墊或者小型 USB 風扇輔助。
Consider a cooling pad — a passive heat-dissipating stand or small USB fan can help in genuinely hot environments.
做齊都仲係過熱？/ Still Overheating After All That?
如果通風同清潔都做好，但盒子依然頻繁死機或者自動重啟，就可能唔止係散熱問題。建議先參考 問題排解頁面 排除軟件因素，如果問題持續，可以查閱 售後服務與保固 或者 聯絡我們。
If ventilation and cleaning are sorted but the box still freezes or reboots frequently, the cause may not be thermal at all. Start with our Troubleshooting page to rule out software factors; if it persists, see After-Sales Service & Warranty or contact us.
另外，如果你發現效能問題主要係播放卡頓而唔係死機，成因好可能係網絡而唔係溫度——可以睇埋 電視盒子播放卡頓？10 個常見解決方法。
Also, if what you're seeing is buffering rather than crashes, the cause is more likely your network than heat — see TV Box Buffering? 10 Common Fixes.
