Just installed an AC Silencer on my 6600GT

Installed the new NV6 Silencer Rev.2 from Artic Cooling on my fast but loud 6600GT. The removal of the old unit and install of new was a breeze (no pun intended). Cleaned off the old thermal paste and added the new included thermal paste and torqued down the two screws and its ready to roll.

New fan unit is LARGE and I had to move some cables to make it fit. It takeds up the space of one expansion slot so you will need the one just below the video card free. The fan itself is large and moves plenty of air quietly across the fins and out the back of the computer.

Here are some before and after:

________before________after

CPU----------38C-------------39C
CASE---------34C_-----------33C
VGA-----------46C-----------41C (IDLE)
----------------72C-----------52C (LOAD)
AMBIENT-----39C-------------40C

edit: just ran 3dmark05 to load the card, WOW what a difference. so the new cooler seems to help tremendously under constant load


Other variables of my system that may be differnet from your's:

I am running the card @500mhz w/ ram @ 1.0 ghz .
I have two 80mm in back but no front case fan.
2 SATA and 2 PATA drives
Chieftec case
 
Yeah, thats pretty good. I did the same thing (with the Silencer and all) with my 6800GT, and I am thoroughly impressed. Never did I expect a GPU cooler to do so much for me. Not only did my GPU temps drop, but so did my ambients and CPU temps. Not a bad cooler, if you ask me 😀 😀 .

What did you do about the memory?

I wondered the exact same thing. I noticed that my old fan used to exhaust (warm air)over the ram probably cooling it somewhat. The Silencer does not have any provisions for ram cooling however, I was able to touch the ram (at least the two that I could reach) and it was barely warm. so maybe the designers at Arctic decided that it was not necessary.


How much quieter is it? well, I tried to to meter the sound before and after but my RS sound level meter only goes down to 60 dB. From my ears, sound level difference was great! I used a flex tube to isolate the loudest component and determined that it was the vga cooler, now, using the same method, it sounds like my HDD and stock intel (prescott) cooler are the culprits. Suprisingly, the 80mm case fans were not the loudest. My Abit AG8 also has a tiny NB cooler that adds to my overall system noise.

A note to the noise issue, a recent article shows that a PC vender is using AC Silencers in their build to make their "quiet" PC.

As far as cooling effectiveness, AC web site shows them partnering with some name brand card maker such as HIS, Sapphire, and Galaxy to be oem provider on some of their cards.

ummmm not much of a decrease for the trouble.....

Did you notice the idle temp within 1C of ambient? doesn't get much better.
At load he went from 33C over ambient to 12C over ambient. Again a pretty nice drop, about 60% of what is physically possible

All this while lowering the noise output of the cooler, which it seems was the primary motivation for the OP.
 
How are your Case and CPU temps COLDER than your ambient temperature...? That doesnt seem correct. But good VGA temp drops. 😛

I think my ambient probe is on the vid card and maybe its near the ram or gpu or just in the part of the case that doesnt get cooled properly. I'm also "dragging" air across the HDD's. I'm reading my ambient and gpu core temp through Nvidia's driver set (coolbits of course).
