Yet another person amazed by the Arctic Cooling NV Silencer 5

NFS4

I slapped one on my PNY GeForce 6800 GT and the difference in noise levels is astronomical!!!!:Q:Q I now have a nearly silent PC. Those folks are gods! 😀
 
Is that a one-way street?
I mean you have to remove thermal tape from the RAM and the GPU and you cannot put it back, can you?
 
On my card, the upgrade is not one-way. Stock coolers for the 6800 (and the GT I believe) use this funky sort of teflon cloth or something, it's almost foamy looking. If you're careful in how you remove your stock HSF, it should go back on just fine later. I used swabs to remove any residue from the GPU and the RAM, and then coated them with the supplied heatsink paste. I also lapped my NV5 a little bit, its surface could stand to be polished at the factory. Idle temps have dropped 7-10C, load temps have dropped even further, so that my card hardly appears to even heat up even after heavy use.
 
Is that funky material attached to the heat sink as well as the GPU and RAM by some kind of adhesive?
 
I also have an NV Silencer 5. The stock tape stays on the stock heatsink. There was no tape on the GPU. I used a large blob of Ceramique on each ram chip, and a thin coating over the GPU.

I sheared off two of the stock cooler's mounting studs when I originally took the heatsinks off to replace the GPU TIM with Ceramique. What crap! Alls well that ends well, I suppose, as I'm also happy with the Silencer. I found idle temps to be only a few degrees cooler, but load temps have dropped 15-20C!
 
Trouble with silent computers is what seems quiet today.... a few days later your power supply or something seems totally noisy. Found out the hard way that it is an expensive taste. Enough of the negative, always glad to be updated on a nice silent solution. :beer:
 
not bad nfs4 if my new 6800 oc is too loud i might consider that if i decide to sign off my warranty...oh yea was teh installation hard? or painless?

Painless. The worse part was removing about 15 or so screws from the stock HSF.
 
Yeah these things are sweet. I love mine. With my PNY 6800 GT I had to buzz down a part of the voltage regulator heatsink to get it to be flat if I tightened it alot. weird....
 
Well, I couldn't stand it anymore. I loved my VGA Silencer v3, it made a huge difference for my ATI 9800 Pro. So, after seeing this thread I had to buy an ATI Silencer 4 for my X800 Pro. The cooler that came with my card is already very quiet (Gigabyte's cooler is better than the others), but it does a piss poor job of cooling the memory chips on the front of the card and does nothing to cool those on the back of card (duh). The ATI Silencer 4 cools them all.

Right now I can o/c my card to 500/500 but higher than that I get artifacts. I hope to get far more with the upgraded cooler.
 
Good to hear this. I just bought a pair of NV5's for my 68000 GT's in SLI. I have a pair of BFG6800GT OC's, and boy are they screamers. I figured I would end up replacing the cpu hsf first, but no way. Especially with these running under 25/ea. Literally, I can hear my computer running in the living room fom the bedroom. Insane. Stock GPU HSF's had to go. Ordered from sidewindercomputers.com. The temp drop is more than just a side benefit, as I'm putting this in a VERY compact case, a very custom antique Victrola record player. the whole thing is 14x14x7", and presents cooling challenges. The slot exhaust will make my life much easier.
 
Got the first NV5 on my primary SLI card last night. I figured it was the hottest one (by 15C), so I believed it would be the most dramatic difference. These coolers are SO much better than stock. My load temps ranged between 85c and 92c on stock clocks with the oem cooler. Now, they've dropped to between 76c and 83c. A very, very impressive 9c drop. I can't really measure the db drop, but I believe it is quieter. My logical brain from audio engineering tells me that it can be no more than a 3db drop due to the ajacent 6800 still on the stock cooler. I'll have a better impression tonight when I put the other cooler on the other card.

For anyone who is not so interested in loudness, but just wants to cool down the VERY hot 6800 cards, I did a test last week of just putting a 25cfm 80mm fan over the 1st 6800, at a right angle to the pcb. It was basically inducting fresh air into the stock air intake, as well as forcing the hot air away from the vicinity of the intake. Doing only that dropped my 85-92 to 80-85. Not as elegant or quiet as the NV5, nor does it evacuate the VERY hot air out of the case, but it's darn cheap for a 7c drop. Still, no regrets, as my pc will be more silent, and my very compact case will not have that heat recirculating.
 
ngray, the drop in noise is ridiculous, if you can hear the stock GPU coolers from the other room, the drop is insane, the NV5 is inaudible (literally)
 
I replaced my BBA X800 Pro HSF with a AC4. Load dropped from 72-74 to about 63-65, idle went from about 52 to about 44. The noise is non-existant now, before I had the stock fan spinning up as the temp went up and it got pretty noisy at full load. With the ram heatsinks I also bumped up the memory to 540Mhz.
 
Schadenfroh - I agree. But I'm not that bad with electronics, and I knew I could swap back pretty easily if there is a problem. In my opinion, running my card at 92c full load was a pretty big risk too.
 
Am I the only one happy with my stock cooler?? The Asus single slot cooler idles @2100-2200rpm (silent) 50ºC core 52ºC ram after 8 hours using it today. When 3d is started noise increases (3300rpm) but the sound is as high as the one from the PSU under full load so no complains here. Is ASUS cooler better or what?

EDIT: I hate noise, I changed my 9800pro cooler with a Giant III with a 120mm fan blowing there for silent running, but I just love how this ASUS cooler works.
 
No McArra, I am happy with my stock cooler also. That's why I'm selling my ATI Silencer 4. I only o/c my card mildly so I don't need the massive cooling provided by it. The stock Gigabyte cooler is bigger and quieter than the ATI standard model.
 
I wish the stock cooler worked for me, but it very much did not. The fans ran almost twice as loud as my PSU, and my load temp was 92c. Both totally unacceptable.
 
do you gusy think that cooler will fit my soon to be card.

the BFG 6800OC

in newegg, is says thats it only for the GT/Ultra or im I just misunderstanding?


has anyone installed this cooler on just a normal 6800?
