With rsync you could add the option: --bwlimit=RATE limit socket I/O bandwidth and select a low enough bandwidth limit to keep the packets flowing at a low rate to remain cool enough for your liking. However, I'll echo what other have said about not worrying about these things. The OEMs must run some rudimentary tests to establish performance envelopes and keep everything tuned just so. Nevertheless, if you do not trust them to produce the best quality products, then we share something in common! LOL! In this case, you may want to open the PC case and use a desktop fan to keep the interior of the case even cooler than usual, during your copying process.
