Fanless PSU

I was wondering are PSUs that are fanless still as efficient as PSUs with fans, do they get more hot and since I will be gaming but not heaving gaming would I still be fine with a fanless one. I play mostly simulators and will be playing on high settings.

If I were you I would never even think about that. it puts your whole PC (and yourself) at risk by exposing it to heat which might make it "blow up" and take other parts with it.

If it was a terrible PSU, sure. The Prime Fanless is overly expensive, but not a bad unit. There's a couple other units that aren't so bad, like the Digifanless.

I mean, that depends on the model in question. The Prime Fanless Titanium still reached 90%+ efficiency but it does run hotter because there is no direct airflow. It's overly expensive and not worth it, imo. You can get a few silent units like the Bitfenix Whisper M or Corsair RMx at less of a price and still achieve low noise.

a high quality unit would be fine. 

Many psu’s have zero rpm mode anyway and only spin up st a certain temp

This is the PSU I got

it says its fanless but it still has a fan, does it mean fanless that it doesn't spin under a certain load, also is this a good PSU I got

Yes the Fans stay off untill 15% load reached.

My PSU´s fan stay´s off untill 50% reached. So you do fine here.

The PSU itself looks fine, but 80+ Gold would be a better choice.

Too bad. 

 

Should have asked first.  There are much better options out there.

Yeah, it says semi-fanless, not fanless. Did you read it and think "hmm, I wonder what the semi part means... Probably nothing"?

This is a fanless power supply:

They can get pretty toasty, if you want a quiet power supply for your desktop get a semi-passive one with zero rpm mode. I have a RM550X and even at 200W the fan stays off so its basically always passive.

So Memory Express recommended a PSU that they had an over-abundance of because people that do their research first know better and never buy it.

 

So when Memory Express gets the good PSUs back in stock, are they going to let you return that one so you can get a good one instead?

 

And why are you buying PSUs from Memory Express when there are typically so many other options out there with much larger selection and inventory?
