Not sure who told you this, but it is incorrect. 7200 RPM drives spin faster and usually have more components inside them than a 5400 RPM drive, both of which will cause more heat.

What generally determines heat within any device is either build quality or airflow (internal, ambient or both). Since HDDs have zero internal airflow, it all depends on ambient temperature and build quality.

Now, that said, there ARE 7200 RPM drives that run cooler than 5400 RPM drives. For example (just an example--not citing actual data here) Seagate may make a 7200 RPM drive that runs cooler than a Samsung 5400 RPM drive. But Samsung's 7200 RPM drive will be warmer than their own 5400 RPM drive 99.9% of the time. Also, Seagate's 5400 RPM drive will run cooler than their 7200 RPM drive 99.9% of the time.

But on average, we're talking maybe 7-10 degrees difference, and still well within the optimal operating temperature of the device. Nothing life-changing. The major heat offenders inside most devices are IC's/logic chips, and RAM.
