i have this laptop fan platform it also works the way that beds do not catch on fire(like i'd be using it on my queensize bed)
 
I have a neat little extra fan right underneath my GPU to keep it from catching on fire, but other than that, stock case fans.
 
Mineral Oil.

On topic:I have a gaming PC with a fan inside it, but my room ALWAYS has the fan ON (the fan on the attached to the ceiling) Whether it is on the fastest speed or second fastest, (my main two that I use) it's always on when I'm at home.

Not on Topic:But for laptops, (ESPECIALLY for GUYS) you shouldn't put your laptop laying on you lap (for to long for 5 mintues its okay. It over heats and burns you legs (and does other stuff but I forgot) and if you are a guy, and it's on your lap, near that area, it over heats in the leg, thigh area... That part has nothing to do with cooling laptops though.
 
H50 Liquid Cooling, large amounts of case fans in a push/pull setup. That and weekly cleanings, every Saturday.
 
Weekly cleaning? Damn. I don't even clean my ROOM weekly.

I built her myself so I like to take extra care of it. I use my air compressor and a trigger grip end to blow all the dust and dog fur out, so no 5$ compressed air cans for me. Once per month I also take it apart and clean all the extra hard to reach spots.

Just a reminder, compressors tend to have condensation in them. So careful.
