9800GX2 without cover?

post #1 of 6
Thread Starter 
I just got my 9800GX2 from Ebay and it will be going into my folding rig this weekend. (Assuming I can find a 2x6 pin to 1x8 pin power adapter ) I just took the cover off it because if I remember correctly, Knitelife says it keeps them cooler. Will they run no problem without the covers? I noticed there are some small metal pieces from the PCB that make a connection to the top and bottom when attached. Are these functional? I wonder if they are for heat transfer, and I worry that they are some sort of ground or something? Can I run without the covers with no problems?

I will also have a 120x38mm Scythe Ultra Kaze blowing full force at or away from the side of the GX2 in my Antec 300. Based on everyone's experience, should I have it blowing on or exhausting from the side of the video card? I will also have two Scythe Slipstream 110CFM fans blowing from the front of the case.

Plastics do little for actual thermal transfer where as metal might some, its only used as a duct to channel air.
As far as the extra fan, so long as yolu have a good exhaust of air, moving air at the CPU HS would be good.

they are in fact metal

temps do drop alot by removing it

the little things yor talkig about, do you mean the little push pads that push on the panel? they are just for extra ground, not required

I have seen many rigs that have GX2's without covers. They do it with w/c blocks too, its pretty much the same thing

I took mine off and it dropped temps about 5-7 degrees if I have air running over the PCB's. Thats the biggest thing. Make sure the air is flowing on BOTH PCB's and you will see a difference.
