It depends on your BIOS version also. I had A02 installed and they were always on slow. I just installed A05 (easiest and fastest BIOS update ever!!!) and they are both OFF. I'm now using i9kfangui to manage them.
I switched from AO4 to AO5 and reverted back to AO4 because I didnt like the idle temps. Some users have reported higher battery life with A05 and I was wondering if this was due to the fans being off more or did Dell do some optimization? (Basically what is the point of changning to A05?, especially if you are going to tweak fan settings with 19kFanGui).
I changed to A05 because I still has A02 installed from when I got my 9300 in June. Also it does seem that even with using 19kFanGui I've gained just over 30 full minutes of battery time!!! I'm now getting 3 hours 48 minutes from a full charge on a 9-cell!
my Toshiba idles at 62C, and fans are both off, shoots up to 86C when playing songs with media play, it's been working fine for 2 and a half years. so don't worry too much about your idle temp, the chips are designed to handle that with ease
I agree with Zephyr here.. My laptop is on my lap 75% of the time and I know when gaming it can get so hot its warm on my legs and even cause me to sweat from the heat. ... And thats only at 42 or so while gaming. I cant imagine an idle temp of 62c ... and 86c!!!!! DAMN!!!
I'd highly suggest opening that up and applying AS5 to bring that temp down.
Huh??? We are talking about LAPtops here right?? Not meant to be used on laps? Have you ever walked through an airport, college or university? Laptops are portable and designed to rest on a persons lap. Yes the 9300 and XPS are a tad larger then most but they are still laptops.
