A two fan system on GA-MA78GM-S2H?

Actually, this topic in a way repeats the parallel one about this wonderful MB. Anyways, I built my system as following:

- Gigabyte GA-MA78GM-S2H
- 4850e
- 512MB Sapphire Radeon HD3450
- Seasonic S12 380W
- Antec SLK3000B

I've managed to install a big Ninja without a fan onto the processor. I've tried to run the system with only one case fan - Scythe S-Flex 1200U. The report of SpeedPort seems to be alright:
HD0: 45 C
Temp2: 25 C
Temp3: 84 C
HD0: 39 C
Temp1: 36 C
Core: 3C

Fan2: 733RPM

I worry actually about the VGA-card, since it has only passive cooling.

My questions are:
how high can be the temperature of a VGA-card?
how can one measure it?
what the temperatures are reported by Speedport. I guess Temp2 is CPU and Temp3 is Nb?
can it be more effective here to use the case fan as for intake or exhaust?

is it ok to run it so or i missed something?

and a side question. it seems the psu makes a lot more noise than the case fan. what would you recommend as a replacement: Modu82+ 625W or something with less power like Corsair or Seasonic S12II.

Thank for your help!

HWMonitor forexample is able to show you the GPU temperature. My 256mb HD 3450 ran passively around 45-48 degree's C, which is not bad considering how small heatsink it has. That card can easily withstand 90's temperatures, like its bigger brothers 3800-series.

Temp 3 can be mosfets or it also can be the famous phantom sensor... Usually temp 1 is CPU and Temp 2 is northbridge...

hi, thanks for the hint.
yes i've checked with HWMonitor. VGA goes upto 60C, so I think it's ok.

should i use the case fan for intake or exhaust?
or maybe i will simply test it.

I think putting fan on exhausts does much more good in your set-up...
