Can anyone comment on the fan noise on a Sanyo PLV-70. The reveiws all say that it is whisper quiet and noise is not a problem. I can't claim this for my machine which is annoyingly distracting and subconciously tiring after an hour or two. Could it be that it is not switching down to the lowest speed after boot up. At switch-on it is more noisey for about 1-2 seconds, it then stays permanently at a second slightly quieter level. Is there a service menu value that has perhaps been set to a higher speed erroneously? Any help, or comments from other owners, would be much appreciated. Thanks.
