Does a hard drive "working hard", i.e. when defragmenting or otherwise continuously active, significantly affect a laptop's temperature?

overheating

Trying to diagnose and fix an overheating Acer 5735 laptop, running speedfan and doing general workload to try and cause the overheat conditions. I notice that windows xp is badly fragmented according to defraggler, at 58% fragmentation.

So I defrag whilst watching the speedfan window, which was at the start reporting high warning style symbols for all of the sensors.

After the defrag, I rebooted and ran a few programs, and even defraggler again and the sensors in speedfan all reported green i.e. not high.

Wondering if there is a correlation between windows fragmentation causing the hard drive to work harder and produce more heat inside the laptop?

dont want to just assume that the problems are resolved, so either speedfan is not accurate enough or fragmentation can lead to additional hard drive heat?

All comments or suggestions welcome.
