Would a set up like this hurt cooling?

Right,

I have an SLK - 800 which was previously running on a sunon 45cfm fan. (80mm) now this guy hooked on a 92mm this way:

Do you think it would work better that way with my 92mm 56cfm sanyo denki fan, or worse?

Thanks,

Massa

put the 80 back on it, the 92mm wont help much more, may even hurt it if the motor housing in the middle is larger.

its more cfms but as u can see lots of the air being pushed down wont hit teh cpu cuz the fan over hangs the heatsink.

WTF LOL

Yeah don't ghetto-rig it, stick with the 45 CFM fan.

Even with "stock" PC's today cooling is becoming a problem because ppl never take the time to really understand air flow characteristics and basic reasoning. Just blowing air around in a case is not going to work much longer. I happen to be designing a new case at this time and have tempted to tackle this very problem. I have found a few basic things that work extremely well.
1. heat rises so place the exhaust fans as hi as possible (1 on each side in the rear)
2. Seal the rear of the cabinet as well as possible so air intake is in the front (low as possible.)
3. Make sure your intake cfm is at least as large as your exhaust.
4. Some of the intake should flow under the HD and CDROM thru vents.
5. Use plastic venturi shaped tubing directed to flow over the ddr and behind the mobo to that side fan.
6. Todays cpu fans are so disruptive to air flow that they should be compared to a model t ford but water cooling is just too cost prohibitive and disastrous
if something breaks.
7. I think vid card manufacturers are finally understanding air flow with theyre turbo type fans which can be easily exhausted with a bit of tubing.
8. dont forget the power supply fan when figuring cfm in and out.
9. Dont figure in the cpu fan or vid card fan into the cfm equation.

As I am still in the design stages I would love to see some input here. I also need input on aggravating things ppl can think of about theyre PC case.
