Was reading around on here and couldn't find anything but here's my problem. I have an HP laptop and last couple days the when i turn it on the fan is making a loud noise. So i bought some of that can air stuff and blew out the fan and turned it back on and it was better for about 20 mins it has this switchable graphics thing and i have certain programs set to high well when i play these the fan comes on faster but the sound seems to go down. I've been worried about it overheating so i downloaded this core temp program and in the middle of a game says the temp of all 4 cores is about 90 degrees Celsius. Just wondering if that is to hot or not and the fan doesn't seem to blow as much out. Anyways any opinions would be nice or advice.
