I've got an XPS L502x, and I feel like the fan is running harder/longer than it should. At idle, temp is hovering around 55C with fan kicking up/down fairly often, doing basic web/email fan kicks in usually. And under load, I measured it sustaining 90C no problem. CPU is an i7-2670qm and has Intel 3000 and GT 525M. Debating if I should try some thermal compound on the cpu/gpu.. I've got no problem doing it skill-wise, but it's a big job, and even somewhat risky especially if it didn't help or made it worse in the end. I have used compressed air, some dust came out but didn't really change anything (i do that every year or so anyway) so it shouldn't be an airflow problem. I guess basic question is, 55C at idle "normal" or is that worth trying to improve. When it comes down to it, the annoyance is the fan speeding up when i'm going basic/simple tasks or even when it's sitting idle and that's what i'm looking to change.
