best aftermarket cooling for 6600GT?

Couldn't find any topics on the NVSilencer 6 Rev 2 so I'm creating one.

I currently have an evga 6600gt in my rig (replaced the dead 6800 until I can afford to go PCI-e). The problem is it's overheating, reaching ~60C at idle and 90+C at load (running rthdribl). Also, when gaming, the computer randomly crashes out of game/reboots.

I'm basically wondering if anyone has experience with the NV Silencer6, and/or which you video gurus would recommend as a better/quieter cooler (anything has to be quieter than this puny hsf, it's driving me nuts). Thanks for your time, and any input is appreciated!
 
Zalman is much, much better. The whole issue of your GPU blowing warm air into your case rather than exhausting it is pretty ridiculous, iMHO and the reason most people buy the NV Silencer.

I used a VF700-CU w/AS5 on my PCIE 6600GT. Idle/load went from 42/73C stock cooling to 36/51C. Overclock went from 567/1120 to 586/1120. Well worth every penny.

basically NV Silencer=slightly lower case temp, Zalman=much lower core temp
 
Thanks for your input! I've been leaning towards the VF700, simply because of a lack of information on the NV6, but if anyone else has any opinions/experiences, kindly let me know! The only reason I hesitate at all is because of my great success using the NV5 on my 6800
 
i disagree with cobbler

i have both zalman and nv silencer installed for my sli 7800 gt

both perform similarly
 
I'm using a zalman myself, and there are a few reasons I chose it over the silencer:
1. It fits many different cards, including the newest ones form Ati and Nv.
2. It cools very well, better than the silencer from what I've heard - especially the all-copper version.
3. It has a smaller profile - it doesnt stick outside the edges of card like the silencer, so it takes up less space.
4. I have good case ventilation, so I'm not worried about venting the hot gpu air outside.

maybe these are very much YMMV then, I had much higher core temps with Silencer, interesting to see others see no difference in performance, thnx Charles

 
Yes, the VF700 fits on the 6600gt agp, because I just installed one. BUT you wont be able to get the ramsinks on the ram due to the design of the agp 6600gt. You CAN cut them down on the side to make them fit though (ask for a guide later).

Also, the silencers dont work with any 6600gt agp cards, so you're stuck with the vf700, which is probably better anyways.
 
Def the Zalman. As for what amenx said, all copper is NOT needed. The difference between an all copper and a copper/aluminum mix is MAYBE 1-2C on temps but it weighs twice as much.
 
I'm using the VF-700Cu with an XFX 6600GT AGP... because the stock HSF sucks a$$... even on stock settings it was at 68C idle (very lame). Now it's in the high 40s, and goes to the mid 50s under full load (BF2 for many hours). Can't say enough good stuff about the Zalman. Worth every penny. Just make sure it fits on your card, they have a guide on their website as to which mfg's cards it works on. The XFX is on the "maybe" list because it sticks up over the edge of the AGP card, but in my case it's OK - no clearance problems. I have an Antec SLK2650 or something like that (I forget the exact model # at the moment).
 
Thanks for all the replies! I'll be picking up the Zalman today or tomorrow, and give you an update on my new temps! (Rivatuner reports ~60C idle and 90+C at load! Also, as for JBT, you're right, I remember researching the difference in heat dissipation between the AlCu and all Cu HSF when I was looking for an upgrade for my CPU HSF, the difference is not much. I'll stick to the AlCu probably for this as well.
 
Just installed the vf700AlCu on my wife's eVGA 6600GT AGP - haven't run it through it's paces yet, but at stock timings it's at 41C idle vs. 65C idle with stock.

Didn't attach the ramsinks, didn't want to hunt for the power tools to grind them down. Won't be overclocking the memory anyway.

Hmmmm...what to do with the ramsinks...

I've been using the Arctic Cooling NV5 on my 6800GT and today I received the Zalman VF700-CU. I removed the AC silencer and installed the VF700 in its place today. My idle temp dropped 5 degrees with the Zalman and that is at the low fan speed setting. My PC is currently very quiet. The Zalman is much quieter than the Arctic Cooling Silencer.

One bone I have to pick with the Arctic Cooling NV5 is that after 6 months of usage the fan began to die. Half the time when I booted up my PC the fan would make a loud rumbling noise and it wouldn't go away until I tilted the computer slightly. This is unacceptable since the main reason I purchased it was to silence my computer. I don't know if the quality improved from the NV5 to the NV6 so YMMV.

The Zalman VF700 is the only VGA cooler I would recommend at this point.
 
Please note that the 6600GT stock heatsink can be very loose leading to high temps. While this article talks about over-volting the Gainward 6600GT, they also point out the problem with its stock heatsink. My XFX 6600GT had the same problem. Idle temps in the 60s; load in the 90s. I reseated my heatsink and it now idles in the 40s; load in the 60s. It cost me nothing but a little time.

Good point. I also got an improvement after taking off the stock heat-sink and reseating it when I got my card too. Its an unavoidable fact these are mass produced and a few will not be seated perfectly in the process.
