personally i use a vacuum cleaner in mine not a very strong one though.if you use one be sure the tip is plastic,and all will be well.also be sure not to be rough with anything with the tip.Ah, no, i wouldn't recommend it...
The problem is; I can't take a screenshot when it's lagging because i can't switch to that program then. All my controls are rendered useless during the lag.2 screenshots will help us pinpoint what is overheating and show how efficient the PSU is under stress.
