Would it be worth it to buy 2 duorbs for my 8800GTXs?

They're currently idleing at 78°C and reach 90°C when gaming... However I'm not having any issues with them.

I would just like to know if getting those would allow me to overclock them a little bit (enough to be worth the 80$ investment) since currently I'm getting yellow dots even at stock settings in AtiTool (never had any artifacts anywhere else though).

Do you think it's the temps that's preventing me to OC the cards? If not, I'm not investing in those duorbs.

If you use Rivatuner, you can just bump the fan speeds up. The fan on my 8800gts defaults to about 50% speed. I used Rivatuner to bump the fan speed up to 70% and that seems to have brought the temps down by a couple of degrees. Not a huge drop but a nice free way of getting a little improvement.

However, lots of people have aftermarket cooling on their 8800 cards around here - seems to really drop their temps a lot.

As e_dogg noted, first bump the fan speed up to what you're comfortable with. I'd say unless you want to get a decent overclock, you could keep the stock cooler.

... there's no point in raising the fan speed in RivaTuner, whenever the GPU's sligthly used it goes 100% at auto mode anyway.

As I stated, I'm getting yellow dots at STOCK clocks with the stock cooler. You probably didn't even read my post man. I bet your just trying to raise your post count or something.

Can anyone smart help me with this?

Those temps seem quite high for 100% fanspeed. Instead of buying aftermarket coolers which are damn expensive you could reseat both cards with as5. Ive heard horror stories about factory tim application

Sounds like a good idea!

So you know some (or have hear of) ppl who removed the heatsink, cleaned the white trash underneath it and applied Artic Silver instead and then actually observed a temp drop?

Maybe someone with more experience with your card will chime in, but ive seen lots of threads with people reapplying tim on the g80 cards and having significant temp drops. Sorry cant think of the numbers off the top of my head.

is the GTX fan config different from the GT, because my GT's fan never kick on past 50% even at hours of gaming

my colmplete system has AS5 on everything. on my cards it droped my idle temp to 45C from 49C and load was droped to 53C from 56C. same with my NB and SB they just cover the chips in that crap and its pointless. but leave the thermal pads on the memory chips

Reseating would be my first move as well. 90c under load @ 100% fan at stock is .... hot. One more thing tho, go with mx-2, and dont forget NOT TO remove the thermal pads on ram and mosfets. There are some nice guides around here, im sure you can find some if you look around.
