I have a Nitro+ 8GB and well, can't hear it in my Fractal R5.
The only thing I don't like is its power consumption. I've seen it reach 200W max, when the GPU was at 76°. Heats the inside of the case, this card.
 
Same here. I had a Sapphire 7970Ghz Vapor-X before the 480 Nitro+. Comparing the two, the Nitro can't be heard, even at load. The CPU fans are louder, which is good for me, since they are actually quiet xD

Cheers! 😛
 
What will be temperature with default fan curve? Is it necessary to adjust fan curve?

Also I read on Sapphire page that Nitro uses high-polymer, aluminum capacitors (16,000 hours). That means that they will last 16 000 hours on their max temperature?
 


I haven't had the need to adjust the curves, since I can barely hear the card running. Now, I have the FPS'es capped at 120 since my monitor is 120Hz. So, for games that I play, where the RX480 can go beyond that number easily, it doesn't run at full load (I haven't seen it pegged at 100% like the 7970), so that might also be the reason why I haven't had the need.

To give you a proper answer, let me do a little bit of research tonight.

Cheers!
 


That would be great. If it is not too loud I will buy Nitro+.
 
Don't forget that all the differences in performance go out of the window as soon as you overclock them manually. If silence is important to you then I can't recommend MSI Twin Frozr enough. It's a bit pricey but for me it was worth it. I got the MSI 1060 and it is INAUDIBLE, even at load.
 
It hit 78c in furmark after about 20 minutes at 70% fan speed .
Ambient temps around 24c, 2 intakes ,1 exhaust

Acceptable I'd say at 100% stress test load.
No CPU usage at that so you can add 5c or so maybe under a gaming load & then knock it back off because it's unlikely the card will be running 100% load all the time.

If you're running a 60htz screen & use vsync at 60fps you're unlikely to push past 80% load & mid 60s temp wise IMO.

The nitro is not noisy IMO, yes you can hear air flowing but that's all.
I very very much doubt you'll hear it above case fans unless they're $30 noctua's.
 
Acceptable noise levels have always been very subjective. I've got 5 140mm case fans that all run at ~600 RPM. There isn't even a "swoosh" to hear. I had a Palit 1060 Dual before and it ran hot(80 C+) and was fairly noisy at 70-80% fan speed. With the MSI the temps top out at around 72C and the fans spin at 50% at max. Up till 60% you can't make out the fan noise in the ambient.

I doubt the Nitro is noisy, I doubt there are noisy 3rd party cards nowadays that aren't blower style. It's just a matter of "can you hear it?" and with the MSI the answer is "no".
 
Vibrations are the worst, I agree
I don't understand how you can hear anything anyway. My Define R5 is pretty soundproof, and the soft humming that I can hear doesn't bother me whatsoever, it even calms me in a way, I know my rig is alive 😀
 


Humming is not soundproof by my definition.
 
my dell power edge 2600 has the most beautiful fan harmonics. it is very pleasing, I never bothered figuring what the chord is but it is something nice. it has solid steel side panels that are at least 20 Gauge or thicker. so it is not loud, it just has the right harmonic to really travel.
 


All Dell and HP computers I've been around have been super quiet, On the contrary, if you build your own PC for cheap rather than buying a cheap Dell or HP, you usually end up with a really noisy system.
 


Ok, I ran furmark for like 10 minutes and this is what I noticed:

With the "auto" profile, the fans ramp up slowly and let the video card sit at 80°C with 50% fan speed; at that %, they are audible, but in-line with the rest of the fans in my PC (sitting at ground level, to my left in a closed case: Thermaltake S41). This case has a top-mounted fan that is not loud and helps a ton with ventilation, so that could also impact my numbers, but not by much. It took the card 2-3 minutes to reach 80°C at 100% load.

I then moved onto the Custom curve and tried different levels:
60% is noticeable and 100% is what you would expect as "loud fans". Not annoying high pitched, luckily. 70% is what I'd classify as "acceptable", but in Auto it never goes that high. That being said, with the fans at 70%, the card went down to ~75°C, so the noise trade-off wasn't worth it IMO.

I'll keep them in Auto for the time being, since Furmark is a worst worst case scenario, I'd say.

@yuka - your results match mine pretty much exactly.
Afterburner profiling is just habit to me now , I use the same saved custom profile on pretty much every system I use or build.
Don't like zero fan profiles on Nvidia cards at all , & personally 75c is the upper limit that I like to see.
 
the 3 His gpu's i have are actually pretty quite at 100% fans. noise was my #1 concern with my dad's pc when i built it and i can turn all 5 case fans, cpu fan and gpu (270x in this pac) all the way to 100% and the whole thing sounds like a gentle summer breeze. you can hear it but not anything "noisy" or annoying. just the low woosh of moving air.

so with normal fan curves, the pc is all but inaudible. it's so quiet spinning up a dvd in the disk drive is actually very annoying since it is such an abnormal sound for the pc to make. a spinning dvd will completely drown out all the fans at 100%!!

do some homework and chose fans wisely and quiet is very easy to come by. as much as i hate His as a company i am impressed with all the cards i got from them. quiet is an understatement for those cards.
 


I wonder what fans you used. I got phanteks's 140mm fans and they're one of the best when it comes down to air pressure/silence. They're still very noticeable at 100%(1200RPM). Inaudible at ~600 and a slight swoosh at ~800-900. I've got 5 as well.
 
I don't like fans. My next build is going to be fanless. Fanless PSU. Passively cooled GPU (GT 710 equivilent in the future). And it's going to be some really low-power, low-clocked CPU with the fan removed off the heat sink. That'll be a fun experiment.
 


There hasn't been a desktop CPU in many years that even the biggest passive cooler can dissipate heat well enough from. I tried it in my server (using a passive cooler) and it had 2 case fans blowing through. The CPU when run up anywhere near 100% would nearly overheat.

Some of those little mini PCs get away with it, but they also can't drive a GPU and the CPU is soldiered to the board.
 


Don't know what you're aiming at exactly, but if it's silence then DIY Perks on youtube had a very interesting project where he's built a PC that was overshadowed by his heartbeat, noise-wise.
 
built a pc for a friend who lived in a mobile home with those ac vents on the floor. deliberately built it so that it would sit on top of the vent and suck the ac into the case from the bottom. ran crazy cold in the summer. course in the winter it had to be moved off the vent since it now pumped out heat and not ac :)

was a fun experiment and proved to be a very cool pc with only the 2 intake fans pulling in and the psu as exhaust from the top.
 
AMD have pretty much lost me on this cycle. I bought the RX480 on launch day but cancelled the next day due to powergate. Then the 1060 came out but I waited for the custom 480s. I figured the 1060 would drive down the 480 price. But after all this waiting the 1060s are significantly cheaper in Holland, with 3GB cards starting at 215 euros and dropping, 30 euros less than the cheapest reference 480 4GB. I figure 3GB of RAM is enough for VR, so I'm going for the 1060.
