So my desktop died recently and i bought a laptop instead of building a new desktop as i may have to go abroad soon. Never used to monitor temperatures on desktop too much as it had alot of fans and a liquid cooled cpu. But gaming on this lap which has a 4th gen i7 hyperthreaded , 12gigs of ram and a gtx 870m im able to game fine. Like say in battlefield 3, i can easily do around 80 fps but in a few minutes gpu and cpu temp's both are above 80 degrees celsius. Just bothers me that the fans kicked in so much and temp's already at that point within minutes. Is this going to shorten the life span of my laptop. Should i tone down graphics settings to medium or high even thought im doing fine in the fps department?
