How much does CPU fan direction matter?

post #1 of 5
Thread Starter 
Hi,

Basically I couldn't fit the heat sink and CPU fan without attaching it the opposite way. The reason I couldn't attach it is because I would need to sacrifice two RAM slots, which I don't want to do.

Here's how I placed it (please excuse the poor quality photo):




How much of a temperature raise do you think I will receive for placing it like this? Could it cause any long-term damage?

thanks

P.S It's a Artic freezer cooler 7 rev 2

well it depents if you like your cpu well done or crispy.... you have the cpu fan struggling to get some air while the exaust fan takes it away. i say.... YEAH you will get hell like temps. Have the fan facing the gpu and the hot air coming out of the cooler will go staight to your upper exaust fan. O r better change cooler tongue.gif I had this exact cooler and its useless . smile.gif

EDIT:what cpu do you have and do you overclock it ??

What you have there is a cooling fustercluck. biggrin.gif
At the very least have your back vent as an intake.

We really need to know more about what you have to really be able to help.

Damage could only be caused by high temperatures with that setup, and it's your job to monitor them. The real problem is your cooler fan is not reversible for mounting.. If you could take it off and turn it around on the cooler, you would have a slightly under-effective single-pull setup. A single fan pushing towards the back is typically ideal because there is air being sucked out by the rear exhaust near the other side of the cooler.

It really comes down to whether you have a means for exhausting that warm air at the top-front of your case. A fan drawing air out somewhere there could help, but turning that rear exhaust fan around to intake is a must. Otherwise, you have two fans blowing at each other causing stagnant air over the VRMs. That's not good at all.

if that top fan is exhaust then do as doyll suggested and make your rear fan intake, that way you will feed the cpu cooler some outside cool air and the top will exhaust your hot air. but really you need a better cpu cooler.
