Subject: Swift SF16-51 fan not spinning — diagnostic guide

Hi MumboFuze,

If your brand-new Swift SF16-51’s fan isn’t spinning—even under load—here’s a step-by-step guide to help isolate the issue. This model was released in late 2024 and features Intel Core Ultra processors with Intel Arc graphics, so some quirks are firmware-related.

🧊 1. BIOS & Firmware Checks

BIOS version: Confirm you're running the latest BIOS from Acer’s support site:🔗 Acer Drivers and Manuals
Thermal profile: Check if Acer Care Center or Windows power settings are set to “Silent” or “Battery Saver.” These may delay fan activation until temps exceed 70°C.

🔍 2. Monitor Temps & Fan RPM

Use tools like:

HWMonitor
Open Hardware Monitor

If RPM stays at 0 even when CPU temps rise, it could indicate:

EC (Embedded Controller) glitch
Fan header issue
Firmware misbehavior

🔄 3. EC & Battery Reset

These resets often restore fan control:

EC Reset

Shut down the laptop.
Disconnect the charger.
Hold the power button for 30 seconds.
Reconnect and boot.

Battery Pinhole Reset

Power off the laptop.
Locate the battery reset pinhole (usually on the bottom panel).
Insert a paperclip and hold for 5–10 seconds.
Wait 1 minute, then reconnect power and boot.

🧪 4. Stress Test

Run a CPU stress test using Cinebench or Prime95. If the fan still doesn’t engage past 80°C, it’s likely a hardware or EC firmware fault.

If it’s a brand new Swift SF16-51 laptop DO NOT open or try to reset anything, as no amount of resetting and/or software giggling and reinstallation will fix this laptops, as its got an internal mainboard fault and for a new laptop this should not be happening.

The fans not spinning is due to a faulty EC chip which is a programmable chip like a bios chip and it needs replacing, which Acer will not do and they will replace your Swift SF16-51 mainboard. So send your laptop to Acer Tech Support in your country and get your be=rand new laptop fixed properly which is my suggestion to you. Good luck and hope this assist you further, as a customer with a new laptop should not have their laptops fans not working.

Swift SF16-51 internals and where the cpu/gpu fans are which either the whole thermal module and fans need replacing or the mainboard needs replacing as its EC chip is faulty.

I got it to work today, but I am not sure how. I restarted my laptop however and not it doesn't spin again. Should I still send it in or do you think it might be software issue?

Yes, I was going to tell you to do a Hard Rest, but that entails opening the back cover of your new SF16-51 laptop, which on a Swift laptop is tricky as you need a prying tool and you could scorch the back cover and that will void your warranty. Btw I know this as I own a Swift SFX14-51G that I've opened the back cover and added an SSD Gen 4 x4 drive, as its very tricky and you need proper prying tools and to be very careful.

Anyway, a hard reset entails taking the battery out and disconnecting the RTC/BIOS battery and then at this batteries mainboard plug, you need to short its + & - pins to reset CMOS and then leaving the laptop idle for 30-60 minutes so that the EC, BQ and bios chips reset, as afterwards the laptops fans should work perfectly, if not, then its either the fans that are fluty (which 2x fans can't go wrong at the same time) or its most likely the EC chip that is the brain and controls these fans spinning and needs changing and reprogramming.

I suggest that you send your Swift SF16-51 to Acer tech Support in your country and get them to fix these cooling fans issues. Good luck and hope all this has been some help to you.
