:Q,

mine never goes above 70C
 
alex007.... I would think... the non-gt has half the ram chips (4 vs 8), and a slower binned, and pipline locked gpu. I believe it's physically the same thing. Just a suggestion however, the 6800Vanilla doesn't run much faster (on average) than a 6600GT, but costs almost $100 more. Just something to consider. The following article really spells it out:

Follow-up... just got the 2nd NV5 on, and WHAT a difference. My VGA coolers were the loudest by far. Now, the loudest is the cpu fan and psu, and neither bother me that much, the db drop was so great. My only beef at this point is that the fan is thicker than 2 slots. It encroaches on the 3rd ajacent slot, and 2, the screws they give you that go on the lugs work out to be so long, they encroach on the slot behind the card too. If the card by the lugs has caps or sinks in just the wrong places, it won't fit. Likewise, putting another full-length card adjacent to the fan side will not fit, but shorter cards (such as lan, modem, many tuners, etc) would fit fine, because the bulk of the cooler remains a true 2-slot design.

So this, I guess, makes it a 2-4 slot cooler!

Thanks for the input all.

The canister filter on my 55 gallon fishtank is the noisest thing in my computer room. And yes I do have my computer and all hardware raised about 6 inches off the floor, "Just incase".

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.

Nope, the cooler on my Leadtek 6800NU is silent! It idles around 56C and load temps only hit 62C.

Not if you get in on the Microcenter deal. It should be about the same price (of course I had already paid almost full price for my Leadtek but I wanted a silent computer)...
 
I just got an nv5 silencer myself today for my evga 6800 gt but had a few problems. The good thing is the noise level is quite a bit less and the overall loudness of my computer is much more tolerable. One problem I ran into was finding the right tightness of the screws on the backplate to hold the cooling unit on the board. If I had the screws too tight, my gpu core temperatures would go way down to like 65 max under load but my memory would run hotter and when I used the "test changes" to overclock my card it wouldn't even pass the stock 1000 mhz. If I had the screws looser however my memory would be alright back at it's old overclock value of 1070 mhz but my core temp would get to about 72 max under load, which is still great as my old gpu core max was 81 under load. Overall it just took quite a bit of time messing around with it to find the right balance between cooling the memory and core. My old overclock was 405/1070 with my evga copper heatsink and stock fan, and with the new nv5 I'm at 415/1070. Not a huge increase but the noise reduction made it worth it imho. All of my temperature tests were done with rhtdribl running. Did anyone else have any weird experiences like this with the tightness of the screws?
 
This same type of cooling is standard on my HIS ATI x800XT and I'm amazed by it. Idle temps are around 35c with the system temp at 30c and the highest I've seen load temps while gaming is 58c. All games differ in temps, with counter strike condition zero load temp while playing is around 42c.

With my old nvidia leadtek 5950 ultra I saw temps as high as 98c, can't be good.

This cooling is the only way, apart from water.
 
I'm glad more people had good luck with them than I did. I got one of the first available NVS5s and it sucked. After taking the ram tampons off and applying a little AS5, my card idle temps dropped 5c with the stock cooler.

And Schadenfroh, I did it on 2 Ultras 😉 Don't fear the reaper 😛

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?

Hey alex007, *raises hand*, I just got done installing an NV5 Silencer on my BFG 6800OC. My NEW Load Temps are my OLD Idle temps. The temperature decrease was that much, and of course it's quiet. I love the Silencer.

Of course, as someone suggested, now I find my self wanting to silence everything! 🙂 After the NV5, then it was the Zalman 7700, and next up, probably, is the rear fan.

Hey bytor33, this is a surprise to me. I've got the previously mentioned BFG 6800 OC. I never tried overclocking my card before installing the NV5 Silencer, but I can't overclock AT ALL. I was able to unlock the card making it 16,1x6. But, when I try to bump the clock speed of either the memory or the processor by 1 mHz the card can't pass "Test Changes". I had read that this was just an 'unlucky card'. But, from what you are saying, I may not have installed the Silencer properly.

Are you serious that by loosening the screws I might be able to overclokc? Would you recommend I try loosening the screws?

Thanks in advance.

Yes, I would try loosening the screws. Since your temps are down your core is probably fine but your memory might not be making full contact with the heatsink if it's too tight. You might gain a few degrees on the core temp but your memory will make better contact and you should be able to overclock at least a little then.
 
jfgeiger: I have the A8N-SLI, which is fortunate to be separated by TWO PCIe x1 slots. The cooler on the primary card fills the slot ajacent, and encroaches on the 2nd. The Secondary card screw lugs also encroach into this 2nd free slot also. So it would take some miracle to find a card that would fit in the one free slot. On any other mobo that does NOT have two free slots between the PCIe x16 slots, I'd say no go. I basically am taking up 5 1/2 slots for my two cards right now.
 
Count me among the beleives now. After replacing my Antec True Power 380 with a Noisetaker and swapping in this Arctice cooler, the loudest thing in my computer is the Zalman 7000AlCu I have running at 1900rpms.

They dont make NV5's for Matrox Schadenfroh 😀:laugh:
 
just got the nv silencer 5 from microcenter. cost came out to 24 bucks because they have 20% all upgrades and accessories. this thing is working better than i could have imagined. my idle temps dropped from 56c to 41c and i can now overclock my 6800 from 350/775 to 400/800. barely audible. great deal!

With shipping, it comes up to about $30.00 for me!

Okay I don't know if my card turned bum after the initial first day honeymoon but it seems to emit a slight clicking sound. It's easily the loudest component in my comp without a doubt. I've done some research over at silentpcreview and apparently the ati 4's and nv 5's almost all have this issue. You guys that have barely audible cards right now...what do you consider quiet? I would just like a reference point to gauge whether their are fault ones out there or some people just tolerate noise a lot better than others.

If your GPU (and RAM) are cool, you can reduce the RPM slightly by inserting a small (10 Ohms) resistor in the electrical path of the fan. This will reduce the RPM (and noise) and increase heat as a result. As long as you make sure that the heat increase is safe, you should be OK. You can increase the resistance to further reduce RPM and noise. Don't overdo it!

It is going to be very difficult to compare noise ("reference point") unless you have both systems that you want to compare.

Someone tells you in a post that they have a quiet cooler. That means nothing! You don't know what else is in their case. You don't even know what else is in their house that is louder that what is in yours! You don't know how sensitive this person is to noise.

It is even worse than that. People have different sensitivity to different audio frequencies. Let's not get into that!
 
KevinH: If a fan makes a different noise than when it was first installed, REPLACE IT. AC has a 6-year warranty on the coolers. Take advantage of it. My experience is that when fans make funny noises, they are getting ready to die, be it in an hour or a year. Murphy dictates that you will not be around for this to happen, and all you'll know is that your pc is turned off or constantly restarting, or the card is dead! Don't risk it, RMA it.
 
Speedfan software should work with the 6800 series.

It effectively undervolts the fan by using pulse width modulation. The video card natively uses PWM anyway.

Has anyone tried hooking the fan lead up to a chassis fan header on the mobo to see if it eliminates the clicking, which I assume is caused by the PWM?
