Hi all,
I have been thinking of getting a new 8800 card, as well as C2D 6320 or 6420, and i was also thinking of replacingmy current cooler with a CNPS9700, now, my question is, should i have it facing the exhaust fan on my pc to blow the air out, or should i have it facing upward to blow the air into my Power Supply Unit intake fan (i have a TT Toughpower 600w) so that the intake into the cooler goes over the NB heatsink, i am thinking of OCing and i have noticed that the NB gets fairly hot atm, i was just wondering will having the intake to the cpu cooler over it lower its temperature any? would this affect the temp of the PSU much? or would the northbridge be fine without directed airflow, i want to try to get my cpu to 2.8Ghz if i can,and as a sidenote, eventhough the northbridge can get fairly warm, leaning toward hot, i have also read in its specifications that it can run up to 105C

Any oppinions appreciated
Thanks,
TJ

BTW if this should be in a diffent section please move it

Hi jono

What i've done with my case is reverse the airflow completely.

I've got a 120mm fan on the front of the case where the hard drives are (default is pulling cold air in), and a 120mm fan on the back of the case, near where the CPU is (default blowing air out)

The reason i reversed this, is because the cold air rushes past the hard drives (warming the air up) and creating a higher ambient temperature inside the case...intern warming up the CPU and the video card.

Might be just enough temp change to help you out if you give it a shot

true, true, but i prefer to have the air going out the back coz there are the filters on the front and i figure i prefer slightly inccreased ambient to having to having the dust clog up my heatsinks. and to be honest, the ambient temperature isnt that high anyway, and the Power Supply Unit is always gonna blow air out, it is a good suggestion, but what would you try if reversing fans isnt an option, ohh and btw, NB temps i would estimate at about 50, maybe 60, even with cover off and almost room temps inside
Thanks for the idea though

EDIT: and even if i could keep the ambient lower, i would still get high-ish temps at the NB beacuse of low air flow in that area, thats why i was thinking of having a CNPS9700 getting its air from down there, to move it around a bit

hmmm....well 50 deg is extremely high for your NB (northbridge for those who aren't fimilar with the term )...you should keep it around 30deg...35deg with overclocking....

the higher temp specifications generally mean that it can hold that much temp without breaking the chip itself...keeping it stable..you want a good 30deg
I had to deal with that for a while, when i was testing how fast my cpu could go

Good point, well, anyhow, ivebeen looking into it, and i think i might get a smaller cooler like the cnps7700 which should provide quie a bit more airflow in that area, especially since the giant cooler wont be in the way of the exhaust, it seems to be running faster now as well, since i realised that i had the speed set lower on my Big Typhoon, also thinking of cheaper cpu, such as e4400 since i should be able to get it at higher speeds with less NB heat due to the lower FSB, and i can put the accumulated money into a better video card, i reckon with the difference in the cooler and cpu prices id save about $60-$70, and for a temperature that i can compare the NB to, its about as warm as a DVD after burning it full of data, so its not that hot anymore

EDIT: and the cpu cooler that is lower to the motherboard should blow more air towards the NB

EDIT(agin):I'm just gonna check prices when it gets closer to the time to buy, but i would still like an answer to my origional ?, would having the cnps9700 or cnps9500 drawing air from below help significantly with cooling the NB
