Can an SSD Overheat?

Yes. While SSDs don’t have the moving parts that generate heat in traditional hard drives they can still get toasty under the right (or wrong) circumstances.

How SSDs Generate Heat

Controller and Chips: The brains of the SSD, the controller and the NAND flash memory chips are the main heat sources. During heavy data transfers they work hard and naturally generate heat.

Enclosure: Many SSDs sit in enclosures or tight spaces within laptops and computers. If airflow is not good enough that heat has nowhere to escape.

Form Factor: M.2 SSDs those slim little sticks that slot directly onto your motherboard are especially likely to overheat. That’s because they usually sit close to other hot components like the graphics card.

What Happens When an SSD Overheats

Throttling: Modern SSDs have built in protection in this scenario. When they get too hot they’ll start slowing down drastically to prevent damage. Transfers will crawl and your system can feel slow and unresponsive.

Data Corruption: In extreme cases excessive heat can lead to errors and data loss though this is less common with most modern SSDs.

Shortened Lifespan: Consistently running your SSD hot will degrade its components faster and shorten its overall lifespan.

Situations That Cause Overheating

Intense Workloads: Sustained, large file transfers, video editing or new high resolution games will make the SSDs run hotter for long periods.

Lack of Airflow: Cramped cases, blocked vents and laptops sitting on soft surfaces hindering ventilation create a hotbox for your SSD. Use a laptop cooling pad to help with this.

M.2 Placement: If your M.2 SSD is placed under a graphics card blasting hot air it’s going to be fairly affected by the overheating of your 20 pound Nvidia graphics card (joking).

Hardware/Firmware Issues: Rarely faulty drives or outdated firmware can cause an SSD to run hotter than expected.

What Can You Do?

Monitoring: Use software like CrystalDiskInfo or HWMonitor to keep an eye on your SSD’s temperature.

Airflow is King: Make sure your case or laptop has good airflow and clean out dust every other month.

M.2 Heatsinks: Many motherboards come with M.2 heatsinks or you can buy them separately to help dissipate heat.

Work in Bursts: If pushing your SSD hard, consider breaking up tasks so it has time to cool down.
