this generaly depends on the heatsink that you are using, some work better with suck, some with blow.Quote:

the best thing you can do is use goole and search about on the tech sites for your heatsink and see what the tests reveiled about the best way.
Or you could run some tests your self - use some sort of temp monitor (motherboard monitor is good) and try the fan both ways and see which is best
HTH
im using cpu cool at the moment. sensor 1 is showing 38 oC and Sensor 2 is wavering between 20 oC and 30 oC
ive just flipped the fan and havent seen a difference yet. <_<
does anybody know which sensor is which? if thers only 1 cpu temp why is ther 2 sensors showing different temps?
i also have two and one is for the motherboard and the other for cpu.
Yeah, sensor 1 will probably be the CPU and sensor 2 will be the northbridge of the motherboard chipset.
lamsy yoou know way too much dude lol :D
can you have a look at my new post i just made?
uh... generally, the fan should be blowing the air AWAY from the CPU. the heatsink is acting as a radiator for the CPU, so you want use the fan to move the hot air away from it.
the fact that your CPU temperature is staying pretty low, and the fan isn't making any difference blowing in either direction just seems to indicate that your heatsink is working very well.
Nope, cpu fans generally blow towards the cpu.Quote:

If your food is too hot, do you blow on it or suck the hot air away from around it ?
The case fan is for removing the hot air.
Yeah, the idea is that you blow more cool air onto the heatsink, so the heat can be transferred to the cool air and taken out of the case by the chassis fan.

that diagram doesn't deal with the CPU fan at all. it's showing how the case fans and PSU fan are meant to work together.Quote:

i may be wrong about the direction the CPU fan blows (i've never installed a fan separately, myself-- all the heatsinks i've bought have come with the fan already attached), but that diagram is only relevant to how the larger airflow scheme works. i've always thought that the reason heatsinks have those fins or indentations under the fan is to allow air to come in under the fan, absorb the heat, and be blown away from the CPU though.

hmmm.... :blink:
um guys......i only have 1 fan in my pc :unsure:
2 including the power pack fan.
i have taken the side off my box because if the record breaking heat wave we are having. im getting a new case , motherboard and cpu soon anyway so i will cool the bollocks off it when i build it :D
a fan mounted paralell to my video card in a psi slot, as many fans allowed mounted on the case front,back and side. the fastest quietest cpu fan possible and and maybe a HD fan too
for this demonstration i will need; a big power pack, and lots of artic silver. :lol: :D :lol:
BTW do Light Cathodes and other box modes generate heat?

It is easy to determine which way the fan blows as long as the blades are curved (I haven't seen any which aren't).
The airflow is always away from the scooped side.

I've never seen any cpu fans that blow away from the cpu, but I suppose it isn't impossible.
Oh, and the top left picture in Lamsey's examples would now be considered wrong (according to Amd and Intel) for an Atx case because the airflow often bypasses the cpu.
Yes... the intake on your PSU should preferably be on the bottom.Quote:
