FOP32-1. Should the fan blow or suck?

I saw over at overclockers.com that they put a 80mm fan on their fop32-1 so i did it and it works great. I have the fan sucking air off the heatsink now. Would it be better to have it blowing air on the heatsink instead.

anyone with one like that give me your thoughts


thanks
 
i tried the fan both ways on my FOP 32-1 and it made no difference whatsoever , but you may wanna try it for yourself and see as no 2 systems are alike.
 
that is why the FOP38 is so loud

because a mass of airflow blowing on the fins of heatsink

and the air is causing all the turbulences and noises

try to suck air out if there is no difference between suck or blow

i believe it will be a little less noise that just blowing onto the heatsink
 
Remember the HS that suck the air away use a cowl to direct the cool air to flow into the lower fins on the HS. Without that the cool air is going to find the path of least resistance and only cool the tips of the HS fins.....with a fan so powerfull that it is hinderd by just being on the HS that may be different.
 
It should blow. Sucking sucks! My Cel 450a locks up if it sucks. It works fine it it blows. Sucking never hits the entire heat sink. Seems to miss the middle where it is needed the most. However if it blows it is forced to cover the entire sink. Just my thoughts.

and the design of FOPs heatsink is not as goos as alphas

alpha can suck air from 4 sides of heatsink and FOPs have only 2 side that let air suck by the fan

that is why i prefer alpha over FOPs
 
one more thing is it depends on your airflow in your case

for my case, i have a case fan that can suck the warrm air out right after the air gone thru the heatsink fan

if i put it blowing onto the heatsink, the warm air will circulate inside my case and it will make the ambient temp rised and on the other hand, my cpu temp is also increasing
 
well i've turned the fan around to blow on the heatsink i think it made maybe a 1-2 degree differnce. Putting that 80mm fan has let me OC more than before though. I'm now at 1Ghz@1208 (11.5x105)
