Does the GTX 512mb really dump heat INSIDE the case? WTF?

The Arctic Silencer barely exhausts any heat from the case, put your finger by the grille on the back and you have just the slightest breeze coming out, barely detectable

I disagree... I have two Silencers, and they pump out some heat. I'm not sure how much airflow you were expecting, but you can certainly feel the air getting pumped out. The difference in temperature on the exhausted air when idle and gaming is significant as well. These things reduced the temps considerably over the stock (copper) KO ACS3 cooler.

As far as [ H ] 's temps go... I don't hold too much stock in anyone measuring temps on a workbench. I don't run my rig on a workbench, but in a case, so I don't have the entire card surrounded by fresh air. I also have a Lian Li case that places the cards at the top (BTXish style), so the desire to have the air exhausted is compounded. It's a great case, but it was definitely designed with the CPU cooling as the primary objective.

I have to agree partially with Rollo... The design of the Silencer is fantastic, but the execution is not as great as it could be. I had to do a sort of "custom" install on mine to get them to work properly that included using the stock rear spreader for the RAM instead of the one that came with the Silencer. As far as the airflow goes... I've already addressed that, it's far from "meager". Construction/implementation issues aside, I'm a fan of the NV5 Silencer... Had one on my 6800GT and now on my two GTX'es, and I've been impressed both times.

True about the effectiveness of the NV5 Silencer over the stock 512MB GTX cooler, we won't know til someone tries... Tell you what, I have the Silencers, why doesn't someone send me a few 512MB GTX'es :)

Bottomline...Avoid a card like this with any presshot or P-D heater system...or extremely oc'd system on the edge thermally.....They have enough problem keeping them cool at stock....

Agreeing with most here. I've owned the NV Silencer and it barely exhausts any air out the back. Its almost unnoticable and temps never really got much better than the stock cooling. I wasn't impressed with the NV Silencer and will probably not buy one again.

Now I've heard that the Zalman is better than the NV Silencer and I may invest in one of those. As far the 512gtx, I wouldnt even mess with cooler, I doubt aftermarket coolers will do any better. Most people that are going to buy these cards will have good cases and case cooling anyway.

What are you guys smoking...? Pass that sh*t...

KO stock
idle:
GPU1 50C
GPu2 51C
load
GPU1 79C
GPU2 83C

NV5 Silencer
idle:
GPU1 45C
GPU2 43C
load
GPU1 69C
GPU2 64C <---- Almost 20C cooler than stock! This is from my own setup, no workbench here... You seriously going to try to tell me that these things aren't any good?

Edit: Just noticed that you have a 6800GT... The Silencers on my GTX'es are considerably louder than the one on my 6800GT was. I beleive that the fan spins faster on these cards, which would explain why I can feel the exhaust on my cards and others are saying the airflow is meager. I'm not sure if the fan speed is dynamically controlled by the cards or not...

All of this is really moot anyway... We'll have to wait until someone tests a stock 512MB GTX cooler against a Silencer. That being said, I'm not really very impressed with the stock cooler hitting 79C load on an open test bench... What is that going to translate to inside a case running a bunch of other gear... What about two in P4 SLI rig...?

thats it nitromullet, the new ones have a top speed of 2500rpm and the old ones 2000. i had the older version, rev 1, i think, and it barely exhausted anything. still did a very good job cooling my overvolted 6800gt (60-65c load temps if i remember correctly) and i was quite happy with it. my opinion of arctic cooling wasdiminished when my ati silencer 5 failed in 3 weeks of using it.

That's interesting... I didn't know they had changed the RPM's. It's good in a way for cooling, but my current "Silencers" certainly aren't silent. Actually, they are the loudest fans in my case. Not louder than the stock KO cooler, but louder then my Zalman CPU fan or any of my 120mm case fans.

It's not necessarily stupid, it just doesn't suit your OC'ing. NV is making sure their part is optimized, they're not trying to optimize your system. They can run the part cooler and quieter like this. They've left the burdon on the consumer to figure out how to accomdate their optimization into the rest of their system.


Well then I would say to Nvidia, my system goes into consideration when I decide whether or not to buy your product, and if you were lazy or whatever in your design of a cooler for a 700 dollar part, perhaps it isn't worth purchasing.

And to those who say the NVSilencer doesn't make much difference:

Before Nv Silencer:

55 idle, 80 load

After

38 idle, 58 load


And a much cooler case.

I too would like the hot air going out of my case. My overall case temp dropped 2c, by adding a NV Silencer. While its not much, every bit helps. My case dropped another few c by adding a Zalman 9500 over my Zalman 7700. Im sure Im more anal than most people about getting the hot air out of the case. Which is why Ive watercooled and phase-changed cool my last several PC's.

I dont see why the current Silenver rev.3 wouldnt fit. It has spots on the heatsinks for 512mb ram. They arent being used on my 256mb GTX, in the 512m they would. I imagine the Silencer would cool better than the stock config.

This post isnt about how cool the GPU is. Its about hot air being kept inside the case.

That's no good for dual slot... but is it true? They are also showing that the GTX gets a temp of 76 degrees load which is really high for dual slot... My regular GTX w/ NVsilencer gets only 56 at load or so

Thats beacuse their fan blows directly on the core instead of routing it like the Silencers and such. It does have a vent for it to leave it just doesn't do any super routing.

Actually, it doenst. The fan is directly over the GPU, by there is no air being blown directly over the GPU. Im not saying the cooler doesnt do a good job, just correcting you.
