Two computer problems

[NLSoldier]

1. My laptop (Dell insirion 9100) has a really loud fan on it. I want to play poker on my computer in class, but the fan is loud enough that its a disturbance to the class. Is there any way to make it quieter, dlean it maybe? Or to disable it altogether (temporily).

2. I have 2 dell 2001fp monitors hooked up to this laptop, and it tends to lag a little bit when I have a lot of stuff runing, namely 8 tables of poker. Would more memory solve this problem?

Thanks in advance.
