Will this Lian-Li accessories help in drawing out excess hot air from those expansion card in my casing? I only got a graphics card there, so would like to know if it is worth it to burn the fan so it can directly draw out the hot air of the graphics card when the heat is removed by its own HSF?

The red circle is where the blower would be placed. VF900CU is installed.

It will help, but not much because ist a pretty puney fan. You are correct to assume that added case air flow will improve card cooling. That bottom corner of Lian-Li cases is a dead air spot.
Solution(s), in order of preference:
Add a fan (20cfm?) inside the case blowing air into the dead spot.
Add additional or higher cfm fans to your case.

Warm air rises so it's not a dead stop.

And the VF-900 cools everything on the card from the GPU, RAM, to VRMs so I don't think you going to see ant benefit at all.

reddevil0728,
I thought about getting this fan for my LL PC-7A case but wasn't impressed with it's specs.
BS-01(blower fan): 12 cm, 2 ball bearing, 1200 RPM, 13.64 CFM, 34.3 dB
The fan is mounted to the back of the case with 4 thumb screws and requires a grilled rear, as on the PC-7 Plus
Is your photo with the red circle of a Lian Li case? There's no grilled opening for the fan's exhaust.

Its a PC7+ FYI, just that I took the picture with the window Side panel on so you can see it.

Is the blower blowing air inwards or is it drawing air out?

Rising isn't the issue. Warm air is. Your VF-900 is possibly just recirculating warm air over the heatsinks. Adding another fan to blow the warm air away from it may improve video card temps.

And, with all the wind inside a case, warm air rising is a myth. It goes wherever the wind pushes it...the VF-900 may be just sucking it back in.

It's easy to test. Just remove a side panel and set up a house fan blowing into the case. If the temps drop significantly, you either have not enough air flowing through the case (all the case air is warm) or a dead spot around the video card (where it is just recirculating the warm air it produces).

The blower pushes air.

Um...

It's an exhaust fan, so it sucks air out of the case and pushes it out a rectangular grill in the back wall.

Personally, I think the brand name and part # says it all... 😀

Hence, it pushes air and not pulls it. I thought it made sense. I have one in my V1100B Plus.

I don't use mine; didn't really see any improvement with it. I have the v2000 and I got it with the blower and the cpu cooling duct, both a complete waste.

I modded a dell mid tower, and to cool the vid card/chipset I just dremeled a spot on the side panel for an 80mm fan. Worked like magic and my mobo/vid card temps dropped dramatically. Almost 10C (I can't remember exactly). I'm going to be enlarging the opening for a 120mm soon. I'll add pics if anyone is interested (it's not all that crazy of a mod 😛)

Yep, I did the same thing. I run my 80mm at 5 volts (Using the connector from the VF-700 that's on the video card) and it added almost no noise while helping cooling quite a bit.

Yeah, it's a pretty straight forward setup. "Hey, my vid card/mobo needs more air. I'll point a fan at it" 😛.

I run an antec 80 with the hi/med/low switch on it. I keep it on high. The extra noise doesn't really bother me too much. But, the 120 should move a touch more air and be a little quieter to boot.

All I need is another vid card and some mem and I'll actually be able to use that computer!

i have it installed and it makes a difference in my case by approx 2-3C when gaming. the amount that it helps depends on your case airflow..
