hey guys , i have some questions about pc cooling.(im noob )
my cpu's temperature is usualy about 50*c when doing nothing.When i open games or utorrent etc., it pops up to ~68-72*c and performance gets aftected drastically.

so, i think wether its because the cpu cooler isn't able to cool the cpu enough, or the ventilaton in the pc itself is bad.I opened the cover of my pc and the cpu temperature falls for about 2-3*c

im using this cooler ( Intel C25704-002 Heatsink Fan - Socket-775 for Pentium 4 / D LGA775 Cooler )

also i wana know if there is any use of this kind of fan ( Computer Fan, Case Fans, Computer Case Fan ) because my other pc hasn't got one ,yet the temperatures are normal.


by the way, i cant really understand this thing - i oppened dxdiag and it says that i have this cpu - Intel(R) Pentium(R) 4 CPU 3.00GHZ (2CPUs).does that mean, i have dual core processor? ( Im colmplete idiot, if it gets about computers xD)



sorry for my bag english
