Mmmmmmmm thing is - the fan is fitted the same way it was fitted when it was inside the PC so why would the power supply fan blow out and the CPU fan blow in? Odd and another reason why computers are not to be trusted!

Because case fans (and power supply fans as they're usually mounted in the top of the case) suck the heat out of an enclosure, while CPU fans move as much air as possible over as big a surface as possible (heat sink fins) to cool it down, and the latter works better when you're blowing.![]()

Sounds good to me - I know knack all about this level of stuff - I fix tanks for a living and shout at folk...............
all the cooling fans on my electric counter balances blow cold air on to the heat sinks not suck, as a blast can be directed and a sucking air can not![]()

This is one area that seems to cause confusion.
The fans in the case can suck air in from the bottom of the case, the CPU fan directs the cool air onto the heat sink to remove the heat which rises the case fans at the rear and the power supply fans blow the hot air out the back off the case.
My thermotake case had 7 fans plus the cpu fans and the power supply fans.
2 fans sucking air in the front over the hard drives.
2 fans sucking air in over the cpu's
2 fans one each per cpu blowing the air over the heat sink.
2 fans at the rear blowing heat out the back.
1 fan on the top to blow the heat out
1 fan on the video card and
3 fans on the power supply to help remove the heat and keep the power supply cool.
Confusion about blow or suck ....... where is this thread likely to be going now, I wonder?
