how many fans is enough?

hi before i start need to clear something up as i am a complete comp hardware newbie ... jus wanna make sure of something.. molex connectors are the 4 pin connectors from the psu right?

how many fans is recommended in a system with the following:
P4 northwood (fink its called) 2.8ghz (has heatsink etc)
GA 8I848P-G
2x 512mb ddr ram
1 bfg 7800gs oc agp
2x hdd
480w truepwoer 2.0 psu
i ahve a antec vcool under where the video card is 1 80mm fan where the hdd is. there is also a side fan connected to a panel and a 80mm fan ontop inside the case. is this enough ventalation for it or should i connect another set of duel 80mm fans under where the psu is?

and how many fans is safe connected to 1 molex connector?

    Yes the big 4-pin is Molex. 2 more 80's under the PSU would help, BUT

    may not be necessary. 2.8 Northwood doesn't create much heat. Monitor

    your case temps, and decide from there. You don't really want them to

    go much over 30C. If you can afford 2 more 80's, and don't mind

    installing them....go for it. Probably 2 "Quiet" fans will still help, without

    increasing the noise level too much. GL :)


    PS. You should be able to hook up alot more fans than you need to a

    Molex, so i wouldn't worry about it.


  2. Molex, right. As many fans as you like, they don't draw too much power.

    If you can fit 2 fans under the PSU then go for it, get them around the 30cfm air flow each.
  3. ok cool, so if i connected the 2x 80mm fans under the psu, the side and top panel fans, the fan where the hdd racks are (total of 5 fans) connected to the one molex connector is alright?

    another question, my computer case comes with a lcd screen that shows the hardware info. It can show the cpu fan's speed but i'm not sure how to plug it in. the fan that is connected to the mobo, do i remove that connector and plug it into the connector that is with the case? (sry if my description is confusing)

    Yes, the 5 fans total would be about the same as 1 cd drive at most.

    Any instructions come with it? Do you have a link or model name/number?
    Leave the fan connected to the mobo until you work it out.
  5. The case is a generic brand. it comes with the world worst instruction manual. it is very simplistic. the instruction manual shows a diagram of supposedly male cpu fan powerline then says " to connect cpu fan, length 850mm. 11p wiving" and thats about it.
  6. Leave the CPU fan connected to the mobo, you can check somethings with Everest home ed or Ultimate ed.

    Connect some other fans to the LCD fan controller.
