...I would use a can of compressed air to blow the dust out of all filters, fans, and heatsinks.
To answer your question, the fans that I would keep are:
- CPU fan
- Rear exhaust case fan
- Whatever fan, if any, is on the video card (extra PCI fan may not be necessary)
- Whatever fan, if any, is on the motherboard chipset(s)
I strongly would advise keeping a front intake case fan to blow over your 3 hard drives. If you only had one HD, you might be OK without the front intake fan.
I like big (120mm) fans wherever a fan is installed.
Round IDE cables may help, too.
Here is my config.
I just got a new ECS 915P-A version 1.2 and a celeron D 346 3.06 GHZ. And the rest is as follows.
1 DVD burner. Maybe a second CD drive soon.
1 IR shield going to motherboard IR port 5.25 device.
1 floppy drive.
Card reader and USB combo 5.25 device
3 SATA hard drives.
BFG 256mb PCI Express video card.
2 side fans. 1 front 1 back. 1 cpu fan.
1 northbridge fan. 1 double pci exhaust blower antec.
Maybe another video card in the AGP compadible slot.
USB 2.0 PCI card.
D-Link 520+ I think WIFI card.
Perhaps 430w antec true power supply with 20 to24 pin converter to match motherboard. But it works fine.
CPU according the bios runs at about 50c and case at 35 or 40 something. But I have so many wires in the PC. The thing is such a mess. I want to build a PC, just move to a new case. Or completely empty the current case.
What I'm wondering is if I remove everything except the CPU fan, PCI express Video card, 1 HD, and 1 DVD burner, will I go up from 50c much.
Because all the clutter is gone. So more air flow.
Or with just a CPU fan only and no ther case or pci fans I'm asking for truble.
