CPU HSF placement question

post #1 of 10
Thread Starter 
My zalman 9700...is the same vertical placement same as this:
http://www.overclock.net/gallery/sho...php/photo/3559
But the difference is that the Fan is facing the back of my case. (the one in the puc is facing the optical drive side.

So my question is that does it matter which side it is facing? which one is better?

It matters alot, basically when the fan is facing the optical drive side, it is blowing the hot air of the cpu on them. If it faces the way as the link shows, the air is sucked out straight away from the rear case fan.

Face your fan the same way as is in the picture..this way the hot air is being pushed out of the case and through the exhaust fan in the back of your case..if youve got one installed...you should noticed a difference in temps.

face it towards the optical like everyone says, that way it PULLS cool air into it and the rear case fan will PULL the "heated" air out.

see my cpu cooler pic, its the same principle:

Does this apply to coolers that are made like the Big Typhoon or Enzotech? There's another that looks like this... can't remember.

The fan is blowing toward the side of the case instead of the back.

I prefer coolers such as the zalmann, they direct heat straight out of the case, which leave the case temps low, hence keeps the ram/vga/northbridge cooler. If a fan blows to the side of the case then make sure that a good rear fan which pulls a good amount of air (CFM) is there, with a good intake fan infront too.

Hey, so this picture's zalman cooler is placed horizontally:


Think this is better than placing it vertically?

ALSO, one more question. When i first boot up my computer for the first time, my zalman 9700's fan was touching the CPU 8 pin cable so it wasnt spinning. I left it like that for about a day and saw it so i moved the cable out of the way, so the fan would work, think any harm was done to the cpu? I wasn't doing any temp monitoring. and CPU wasn't OC'ed either.. what do u think?

depends how hot the day was but my fan wouldnt spin with smart fan enabled and only idled at 37c and i was able to benchmark without it running but i have a 12cm fan on the side which blows onto it, your computer would have frozen if the was a problem.

it was spring time in Oregon, the weather was cool. i guess it was ok, e6600 at stock, i dont think the zalman 9700 without the fan running would cause anything, plus i wasn't doing anything. it was just idle overnight and i moved the cable. But i did install vista during that time..( first time boot )

how about the placement question?
