PSU fan noise

post #1 of 17
Thread Starter 
So, I just installed a Rheosmart fan controller and got everything nice n' quiet... except for the psu fan. I have a CORSAIR Enthusiast Series TX750 V2 750W Bronze Cert. in my rig currently. I'm really not sure whether or not it was this loud before, as the rest of the fans in my case were running louder in general, but it's definitely noticeable now that I have silenced everything. (I can turn off all of my fans, other than the cpu, which idles in the 600s anyway, and have an almost inaudible drop in the noise level; it's all coming from the psu) While it isn't 'loud' per se, it kind of defeats half the purpose of getting s a fan controller in the first place. Is there any way I can remedy this?

It's not coil squeal? Just buy a new fan (140/135/120mm depending on whats currently in it) and pop that in. You could call up Corsair but it's probably not worth it.

honestly, nothing you can do except get another psu or....


you can replace the fan on the psu but that'll void your warranty.

Damned if I do, damned if I don't, it seems... It is definitely not 'coil squeak'; all it sounds like is a high volume of air being moved. Are there some PSUs that are known to be quieter/louder than others? What RPM do these things typically put out?

definitely

on the top of my mind, the x750 from seasonic would do your system justice but it really goes to how many watts do you want for how much. i can recommend a better psu once that is given.

btw the x750's fan doesn't spin until load kicks in o.O (so that's true silence right there) ~lol silence is something that is a necessity in my system so i feel for you.

replacing fan will most certainly void your warranty

is it loud idling or when you game or something

you 580 is pulling so many watts probably that you psu heats up and fan kicks in

I guess you could buy that monster psu that doesnt heat up when a 900 hz 580 is installed

The Yate Loon D14BH-12 in the unit is not configured to be that quiet at high loads.

Obviously different review sites do not measure noise the same way, but here are some figures for the TX750 V2:
http://www.technic3d.com/review/netz...-im-test/4.htm
http://www.kitguru.net/components/po...pply-review/4/
http://www.pc-max.de/artikel/netztei...-750-watt/8842

But I wouldn't think it would be that loud at idle, just under load.

As an idea of what is quiet at about 500W and below (what you're using) at around room temperatures, see here:
http://www.silentpcreview.com/article1203-page4.html

So certain 500W units even would be quieter than the TX750 V2 at the loads you're looking at. Probably.

I think I'm going to pull the psu out and have a look at it in operation. I'm pretty sure it was definitely less noisy at idle a few days ago. Idle noise is what I'm talking about.

I removed the PSU from my unit and checked it out, and it seems perfectly fine function wise, but the fan is just spinning quickly + turbulence = breaking the peace. I've found many threads like this so, I'm beginning to realize that there is nothing at all wrong with my psu, but that the model is not built to be quiet (despite their advertised "ultra-quiet" cooling). I'm about 30 days out from my Newegg refund policy, so I'm SOL at this point. I'd very much like to grab a silent psu (even 850w, as I've been considering an SLI set-up in the future), but I'd be saddled with a $120 brick.
