Well yesterday I had fun while hacking my new NEC 355A DVD-RW to a NEC 4551A DVD-RW enabling DVD-RAM support and LabelFlash support (similar to LightScribe for those who dont know, I never heard of LabelFlash until I got the sale on the NEC).

I woke up today with my techie blood still flowing strongly so I decided to start working on my case cooling a bit. I was curious to see if adding another exhaust fan by my gfx card to see if it might drop the temps a bit before I change the cooler to a Zalman VF700-Cu LED (arriving on monday ;) ).

I removed the pci slot covers from the empty slots and zip tied the fan (my stock 72mm fan from my X2 stock hsf) on the outside since it couldn't fit inside. Then I did some minor cable management and dusting (I took pics before I cleaned up lol, doh hate on the dust on meh sound card <_< )

Next time I open up my case for something I will slip the fan power cable below the sound card's pci slot to hide it. Replaced the side panel and booted up and went on irc for a bit then checked my gpu temps. However, there was no noticable difference between the temps before and temps after :(

So after a while I went planning my next few mods and thing using some pics (MS Paint ftw) then I went to check my temps again for idleness. I realised that all three of my exhaust fans (the main 120mm, the psu exhaust and the new 72mm) were all exhausting much cooler air than when it was just the 120mm and psu exhaust. Checked my temps again and noticed that my cpu doesnt cross 30C idle (from 33-35C before mod) and my chipset doesnt cross 45C (from 46-48C before mod). Which means my ram also runs cooler.

So my lil mod dropped my ambient case temp by 2-5C which is a big enough deal for me :D
I haven't really seen anyone do this mod before. Probably because most people use more of their pci slots than I do. But if you dont and you have a extra fan lying around. Feel free to try this out.

hey it's a little ghetto but if it lowers temps it's all good :D would look a bit nicer if you had one of those chrome/brushed aluminum fans back there though, maybe a custom grill for good measure ;)
 
Maybe I can do that when I have some extra $$ lol
Right now im saving to purchase two 120mm fans to finish this mod :D :

not bad. Although the big pic at the bottom showing your case on top of an old enclosure box and the MS Paint diagram almost belong in the ghetto mods thread.
 
I'd consider simply moving the lower rear vent fan to the lower 'blue' marked position - if you're happy with your operating temps.

Using only rear-vent fans tends to create negative case pressure, possibly stalling air-flow through your power supply.

More fans = more noise. Two should do!

Hope this helps!
