My Playstation 2 slim which I had since 2005 has always had overheating problems and the fan is very noisy. Any suggestions?

Buy a ps2 cooler from a local electronics market

I use to have a slimline but now i have the big ps2 that i got last christmas. i would get the big one if i was you. the big one has a wifi ability and the slimline doesnt. the big ps2 is bigger soo it has more space inside so it doesnt overheat as fast. although the first big ps2 i had, the disk tray broke because i was not pressing the disktray button and was just pushing it in instead. this is my second big ps2. get the big ps2 its way better
