With rsync you could add the option: |
| 67 |
|
| 68 |
--bwlimit=RATE limit socket I/O bandwidth |
| 69 |
|
| 70 |
and select a low enough bandwidth limit to keep the packets flowing at a low |
| 71 |
rate to remain cool enough for your liking. |
| 72 |
|
| 73 |
However, I'll echo what other have said about not worrying about these things. |
| 74 |
The OEMs must run some rudimentary tests to establish performance envelopes |
| 75 |
and keep everything tuned just so. |
| 76 |
|
| 77 |
Nevertheless, if you do not trust them to produce the best quality products, |
| 78 |
then we share something in common! LOL! |
| 79 |
|
| 80 |
In this case, you may want to open the PC case and use a desktop fan to keep |
| 81 |
the interior of the case even cooler than usual, during your copying process. |
