Need a better cooling solution?

[cab00se]

I'll start with basic specs:

Lian-li PC6077B case (3 fans: front intake, top intake, rear exhaust, all 80mm)
ASUS A8N32-SLI Deluxe
3200+ Venice
2 GB's OCZ PC3200
eVGA 7800GT (the 516)
Soundblaster X-Fi

Nothing is overclocked at the moment, and everything is running on stock cooling. My problem is that I'm experiencing a lot of minor artifacting and texture flicker in games, and I'm assuming that it's a heat issue. I can stick another 80mm exaust fan into the rear of my case, but I doubt that's going to make a signifcant enough difference to alleviate this artifacting.

Can anyone make some other suggestions? I already plan on putting an XP-90 and a panaflo on the processor for overclocking purposes, but I don't know squat about after-market video card coolers. Also, does anyone know if the eVGA cards have an on-board temperature sensor like some of the newer ATI cards do? Getting an accurate temp reading would be invaluable.

It's honestly not all that noticable or distracting, but considering how much money I just spent on putting this rig together, I don't think it's unreasonable to expect a little better performance out of this card. Any advice is much apprecaited.

NV temp logger for temp readings. You should also be able to access temp readings through the driver options.

Your card has a temp sensor, and assuming the heatsink is making proper contact with the GPU, your load temperatures should not go above 75-80C, depending of course on ambient temp (I am assuing in the neighborhood of 25C room temp). Idle temps are less important, but should be below 50-55C with stock cooling.

In my experience with my 7800GT, artifacting really becomes noticeable when I try to push the OC too far; backing down a bit alleviates the problem. I have never seen artifacting that I could definitively link back to heat (up to 82C at full load at one point), which is not to say that such could not be the case.
