    Default Newb question about cpu fans

    Alright, I know this is a newby question, but when attaching the fan to the hsf, should airflow blow into the cpu or away from the cpu?

    Actually, it can go either if you want. Your going to get the best cooling performance by blowing it towards the cpu though.

    Actually this question is not as simple as most think.

    With most heatsinks you blow down towards the processor. If you're using a heatsink like an Alpha which uses a shroud, it might be better to suck away since air is forced in at the bottom of the heatsink.

    What are you using exactly?

    Thanks for your responses! I am using an AMD 64 3200+ with an XP-120 with a Sunon 120x38 mm fan.

    Oh in that case blow towards the heatsink!

    i'll be getting a coolermaster cm stacker for my 64 rig in october. it has a 120mm fan for intake at the front and another one at the back. think 2 Sunon's or Tornados is to much? i already have a tornado on my athlon setup for the cpu 80mm. i understand that the 120mm's are much quieter than the 80mm due to them not have to spin as fast to move more air. oh and the case also has an 80mm blowhole. a tornado for that also? or should i just go for water cooling?

    I'm going to be doing water cooling in the spring on mine...when I upgrade to 64...

    tornado's are quite costly...and it will be pretty high maintenance because of the amount of air it pushes...it will collect dust faster, thus inhibiting performance...so i wouldnt put tornados in it...

    If you're going to oc alot then get water cooling. If not, then go for the cm stacker with fans. (I love that case) If you find that it gets hot enough, you might consider a tornado on the top...

    Shiz (now Avid6eek) was complaining that having a watercooling setup really cramped his style because it was so difficult to upgrade (and we all know how that boy likes to swap out parts in his rig). The advantage of watercooling is definitely the quiet, but in terms of actual cooling, a good aircooling setup gives comparable cooling these days.
