unknownuser200 Posted April 21, 2010 Posted April 21, 2010 http://www.tweaktown.com/reviews/3242/sapp...card/index.html Saw this out front thought id bring it here to discuss... i gotta question one thing on though... the noise level... im having a hard time trying to swallow them claiming the cooler is louder then the reference card... i really do... esp being the cooler was designed specifically for silence Share this post Link to post Share on other sites More sharing options...
hierovision Posted April 21, 2010 Posted April 21, 2010 It has 3 fans that exhaust into the case vs. 1 fan that exhausts out of the case for the reference cooler. I think the silver lining here is that it's still quieter than the 480 and 470 at load. 4GB on a video card... amazing. Share this post Link to post Share on other sites More sharing options...
unknownuser200 Posted April 21, 2010 Posted April 21, 2010 it was still deisgned with the attention of being extremely quiet... soo you got me why its so "loud" Share this post Link to post Share on other sites More sharing options...
Water_Hazard Posted April 21, 2010 Posted April 21, 2010 it was still deisgned with the attention of being extremely quiet... soo you got me why its so "loud" If they set the fan speed to the same speed for testing, or left it on auto, I'm sure that the 3 fans would be louder than 1. Plus they would be blowing air toward the mic rather than pulling air away. If you look at the temps though, the temps are a lot lower than the reference cooler. I'm sure you could cut the fan speed down twice as much as you could with the reference cooler, and still get close to the same temps, plus the card would probably be near dead silent.

unknownuser200 Posted April 21, 2010 Posted April 21, 2010 if you did your research instead of assuming youd know that there an impellar based design fan which have a wide blade spacing... run at a low rpm... and do not have a shourd for a reason.... to put it bluntly there ment to run quietly.. infact there suppose to be .5 sone which is 24.5 DBA ... compared to reference 44.5dba... quanity of fans has nothing to do with it...

ebarone Posted April 21, 2010 Posted April 21, 2010 You're saying that the new fans are supposed to only output 24.5 dba each, but you're wondering why three of them together in unison are louder than 44.5 dba? The test listed them at 64dba, or (very) roughly the sound output of one of the fans multiplied by the number of fans there is... so whats hard to believe about that?

ccokeman Posted April 22, 2010 Posted April 22, 2010 I have one in my hands and it really is not 64 dba loud. That loud sounds like a hair drier and that it does not do! If my case fans are louder than it then well ........... Share this post Link to post Share on other sites More sharing options...
The Smith Posted April 22, 2010 Posted April 22, 2010 Heck, that's louder than a Vantec Tornado. That's impossible. As Nate said, decibels do not add like this, except when you're talking about gain in a frequency filter. Share this post Link to post Share on other sites More sharing options...
Hedghawg71 Posted April 22, 2010 Posted April 22, 2010 Those look like the Artic Cooling HS for the 4870 X2's. The are heavy as hell and take up 3 spaces on the 4870 X2's. They're not loud at all though. I tried a set of those on my cards a while ago I picked up off of craigslist for like $60 NIB for both in Fort Worth. I went back to stock cooling not because they didn't work because they cooled well in my Antec 1200 but more on the reasons that they were stressing out my pci express slots and the cards because of the weight. I sure hope Sapphire puts 2 more ounces of copper on the pcb. Share this post Link to post Share on other sites More sharing options...
