I was wondering about my computers temperature becuase I read some other articles about for example the temp of my CPU and HD and I started to think and I came to a conclusion that I had never wondered about my computers temperature. So I decided to check it and there you go:
-My CPU was
HOT (55-60 C)!
-My HD were in 20-25 C (Okay I guess)
So I became to worry about my CPU (AMD Athlon XP 2000+) because too hot is bad for it right? So I did some things:
-I took all the dust out from the cases and inside my computer
-Some parts I needed to use humid paper so get it off
-And I put 3 ventilations (the ones that you normally use when its hot in the house, like in summer)And I let it stay like that for an 30 something
And I was wondering, is this bad? Am I doing wrong by doing this? Also my doubt was
Can I have the case of my computer opened with 1 ventilation machine beside it so that the temperature can decrease? I hope it doesnt make any problems to my computer and if so I am directly going to open the case and every time I use my computer im going to have the ventilation machine on

I dont want to spend any money in ventilation machines for the computer. Thats why I am asking this to check if it doesnt damamge or hurt the computer.
thanks for the attention
