6950 TFIII or 6970 Lightning or AM cooling

post #1 of 13
Thread Starter 
So here is the scoop, I have a 6950 Reference card and I was really worried about the temps I was hitting with shader unlock 90C under load. After much research and some helpful info on OC.net just seams I have a "hot card" so OC sucks.

Overall i'm pretty happy with the 6950 but we could always use more power right?

Options:
I either buy an after-market cooler (AC Xtreme 3 w/V0001 kit) $80 approx
Replace with TFIII (sell existing card $200) $299-$200 = $99 approx
or Replace with Lightning (sell existing card $200) $390-$200 = $190 approx

Last option which i'm kind of leaning towards CF TFIII $598-$200 = $398 approx

Will the TFIII/Lightning Cooler be quite and cool as-well as after-market? I read mixed reviews

The TFIII's are pretty sick GPU's. I can tell you mine runs cool and quiet, when I want/need it to. If it gets hot you can turn the fans up and the dual fans take care of business. I run mine at 70% and it is somewhat loud but temps never go above 71C playing the witcher 2 in my hot room 80F. I would go with the TFIII for sure though.

Edit: TFIII at 70% is about as loud as my GTX 285 at 100%. So it is a pretty big difference.

As a 6950 TF III owner I highly recommend them. The cooler is really good, I run mine OC'd (See Sig for clocks) and it never breaks 55c.

I also use ATi tray tools to underclock its 2D mode to 400/600 @0.700v. Its running two 1080p screens with that and idles at 40-44c with a fan speed of 25% (1000rpm = Silent).

My rig is a difficult mix of media center and gaming rig, but the 6950 fits the bill on both.

+2 for TFIII

Do they have the dual bios switch of reference cards? or is the switch for fan profiles only?

Its a fan profile only switch...I have done a bit of messing with bios flashing. I tried just unlocking the shaders and it didn't change in gpu-z, but i've also been told it can change without showing in gpu-z, so i don't know. Because that didn't really work I didn't try a full 6970 bios flash. But to be honest the performance is so good I don't see the need anyway.

With my fan at 50% I can hear it but its not loud. My card isles at 40c and hits 74c playing Bad CO. I have a side fan blowing on the card and I added another fan by using zip ties in my drive bay. The lighting is huge and all air is blocked from rising so I need the extra fans to help move dead hot air. It's a great card and I'm happy with it.

People and there airflow, my cramped case still only has my tf3 load up to like 65*C and I haven't heard the thing except when I manually set the fan to 100%.
