Thought those $15 phone cooling fans were a total gimmick

My phone kept overheating during long gaming sessions, so I grabbed one off Amazon as a joke. After using it for a month, I'm shocked it actually works. It clips onto the back and has a tiny fan that spins up. My phone's battery temp dropped from like 105 degrees to 85 during a 2-hour Genshin Impact run. The frame rate stopped dropping so much, which was the real win. I still think it looks kinda silly, but the performance boost is real. Anyone know a less bulky option that does the same thing?

You're right about the performance boost, but that temperature drop is the real story. Modern phones start to slow down their processors well before they hit 105 degrees for safety. Keeping it at 85 lets the chip run at its full speed for longer, which is why your frame rate improved. As for less bulky options, some newer phone cases have built-in cooling channels, but they're often more expensive than the clip-on fan.

Wait, 105 degrees?! That's the safety cutoff? My phone gets so hot sometimes I swear I could fry an egg on it, but I never knew the exact number. No wonder my games get all choppy in the summer, the thing is probably freaking out trying not to melt itself. They really build these things to cook themselves before they slow down.

Actually, 105 is Celsius, not Fahrenheit. Your phone would be toast at 105°F lol.
