I was wonder if I should put two fans on the SI-97. One on top of the fins and one underneath the fins. Will it help lower temp?

thx

What do you want to do? Overclock a barton 200%?!?!? On the serious side, it could help a little (a very little bit). Though I don't understand why you would need such a setup. The SI-97 is very efficient and with one fan, should easily cool your processor. When two fans are that close together, the air turbulance would be excessively loud. Now that I think of it, perhaps a ducted push pull system might work, but I still don't think it will help that much.

Try and see what happens with one fan. If you're not satisfied you could try another fan. If i was you I wouldn't put it on the oposite side of the fins, instead I would put it perpendicular to the fan on top, this way it can cool the little base and heatpipes. But I doubt you'll need to do any of this I have yet to see my XP-M go over 35C with a 2000RPM fan on it (of course I do have pretty good airflow in the case itself)

Have you got high temp with SI-97 + one fan? If that's the case you may need to look at seating of SI-97 and/or may be case airflow.

I have SI-97 with a 92mm fan connected through fanmate at lowest setting, I don't even need to increase fan speed when gaming - and that's with only one 120 case fan. :D

Edit: Forgot to mention it's a Barton 2600+. VGA is Radeon 9550 with Tt Fanless Heatpipe VGA Cooler.

Why two fans - just add a 6000 rpm Delta :twisted:
Seriosly - 1 slow fan cools an XP 3200+ quite well so it would be unnecessary.

I just did the opposite: I removed my exhaust fan(12cm 1600rpm antec @ 5v) and ducted the nexus on my SI97 to that oppening, temperatures are the same, or just a bit higher. So, I would very much advise against putting 2 fans on one.
