Fanless Power Supply

[makaveli158]

I have a long term goal of transitioning to a near-silent build.

 

I'm envisioning 3 total system fans with low-noise adapters/low RPM settings; An AIO water CPU cooler with 2 fans on the rad, and likely a Fury X with 1 fan on the rad. Maybe 1 additional exhaust fan if temps are out of control (though I doubt it'll be needed.)

 

I currently have an XFX 650w PSU, which does a fantastic job, but it's just 1 more fan I want to get rid of. And I want a modular PSU.

 

As I understand it, I have two distinct options. I can get a pure fanless PSU, or I can get a PSU that turns the fans off at low loads so I'd want a PSU that is overkill (in wattage) for my system.

 

Does anyone have any personal experience or recommendations for fanless/fanless mode modular PSUs?

People will rip on me for having a 750 watt with a xeon and a 750ti. (or having a psu that costs as much as my gpu LOL) but the truth of the matter is I bought it this way, and well, I thought it was silly until I gamed.

 

 

...full load, my pc is dead silent. nothing. literally the only noise if from the hard drive.

I'd go for the overkill PSU with fanless mode. I bought an 850W PSU, fan has NEVER turned on. Now I just need to replace my case fans with something more quiet...!

Corsair HX series PSUs are good if you want something quiet. The fans don't turn on till they get to a certain load/temp.

Fanless PSUs usually require you to have some fans somewhere else to keep it cool in there. An overkill PSU so that the fan would never come on is probably a better option for most.

The pumps on those are SO FAR from being silent.

 

When trying to be quiet air cooling rains supreme, unless you have money to burn on a custom loop.

I have a Corsair H100i gtx and I've never even heard the pump, I wasn't quite convinced it was even running. Of course I'll re-evaluate that once I ultimately remove more fans from my case.

 

(I also think I want to swap the H100i for a H110, because 140mm fans should be even quieter.)

 

But I do think Linus in his silent build used a Dark Rock cpu cooler and didn't even use a fan or AIO..... I'm not going for total silence at least, just a nice soft hum under load.

When I had a laptop and low-end PC I never gave a damn about quietness, because my machines WERE quiet. Then I started overclocking, upgrading, adding fans, tried some coin mining, etc.....

 

Before I knew it I was rocking an open-mesh case (Thermaltake V3 black) with an overclocked CPU with 2 fans on the heatsink (Hyper 212 evo) running at high speeds under load, a front intake fan with no PWM fan control so it ran at max speeds (over 30db), an exhaust fan, my PSU fan, and a 290x with 3 cooling fans................ no headphones in the world or custom fan curves are going to suppress 8 fans going crazy under load.

 

 

 

Some Noctua NF-F12s, a sound dampening Be Quiet case, an H100i later my noise level is reigned back to tolerable levels - but I certainly have plans to take it further.

You clearly did not read my post. I bought the system that way, and I thought it was silly to have such a high wattage power supply until actually using it.

ROFL on the massive insult on a 130$ purchase I didn't even make shooting for silence, yet people who spend 600-800 on a nice watercooling set up trying to do the same thing. I also have a 80$ cpu cooler, and 40$ in fans.

Once again I bought this way and I'd personally wouldn't of done it this way until I tried it. I can leave my pc on 24/7 mining, rendering, running game servers, why? Produces near no heat. No noise.

Another added benefit, I got this pc 4 months ago, it has 2 exaust fans and that's it. So zero filtering, and negative pressure. Worse possible case for dust management. Well. Opened it up yesterday to not find a single spec of dust. Mint. It looks like the pc was just built. Why? The case fans are off 80% of the time, and when they do come on they only need their lowest possible speed.

Edit: why do people always assume people game on a tech fourm. I went from 2 7970s to a 750ti, and I'm a million times happier now. Why? I just tested a 7970. It makes more heat and noise at idle then my 750ti under load. And I hardly game, and when I do its indie games, so I honestly don't need more gpu power

Yeah, I'm sorry for assuming you game. 

As for you "buying the system that way" I don't think that puts you in a great position as I can only assume you bought it prebuilt, that's even worse. And "buying it that way" does not really explain why you would even look at a system that puts out so little power yet the PSU's wattage is almost triple of what it puts out. What you have there is a Maxwell GPU, some models which don't even need power pin connectors from the PSU as they get the power from the motherboard. I'm not sure what Intel Xeon you're using as you never mentioned but I am 100% sure it's not the 200W one, even if it was it wouldn't justify the PSU.

As for you I'm not sure a fanless PSU would solve anything as you said you have 8 freaking fans. If you really want one, literally get any brand fanless PSU, you can't go wrong.

As for ME, I have a 2000 RPM CPU heatsink fan and the two fans on the GPU and the PSU fan, I'm all for confort and preference but sacrificing your fucking helicopter for a tricycle is just really questionable. I'm sure that Kyuubixchidori's 7970 crossfire set-up couldn't output that much heat and noise, as they are 2 cards working on really weak, indie games, as he mentioned, so if they're on low load I don't see how they can output that much heat and noise.

You migth call me insane but:

- 2x GTX980 + i7 4790k, pulling ~450 to 500 watts

- PSU: Enermax Digifanless 550 watts, 605 watts for <60 seconds

I have absolutely no artificial airflow since the system is fully passive cooled. But the PSU stays cool (<70℃, even in thr hot summer).

Passive systems are possible, but you have to know what you do.
