I have 2 x 120 mm Adda fans in my shiny new PC7.
Thing is, I'm finding them a bit noisy.
Are they just pushing a lot of air and therefore a fan controller will sort them out or are they noisy fans?

If a fan controller is the way, anyone recommend one that looks good in the case? I don't want to put something naff in, but I'm not sure about 22 quid on the Lian-li controller.

Cheers.
 
How do we know If they are pushing a lot of air, thats somit you have to check ;)
put you hand behind the fan.

A Fan controller will be able to reduce the volume of the fans whilst reducing the speed, and therefore airflow of them.

As for the Fancontroller, I have the Akasa fan controller with the led screen ,its nice and looks good.
But for it to fit it, well, that is more down to personal taste.
 
The TR3a does not allow you to turn down the fans, and if it does it must be very complicated :p

Only you can answer that, although the graphics card, northbridge and processor fans usually make much more noise than the case ones.

Try just unplugged the case fans and see how noisey it is then.
 
I know it's the case fans, as all my kit was in a different case only a week ago with one very quiet Akasa Amber fan.

As to how much air they are pushing - feels like a good amount, but its all relative aint it? What I want to know is - are they pushing like 70-75 CFM, in which case that's why they are loud and turning down to 40-50 will quiet them, or are they only pushing 40-50 and then I'd be better getting some quieter fans, eg Ambers?

The Lian-li site is very low on info.

It's not like listening to a jet taking off, just a bit too loud for eg web browsing.

cheers.
 
Fan specs are a waste of time, NONE of the manufacturers have anything like acurate specs.

Just 7v or 5v them and then check your temperatures, if they are ok then good, if not get some ambers in there and 7v them as ambers at 12v are terrible for noise too.

Also which case was the rig in before?
 
Er, all my stuff was in a particulalry vile beige thing from c. 2001!

Temps are 11C cooler for the CPU and over 15C cooler for the gfx, so I'm pretty happy with that difference at the mo!

I'll try 7 V modding them, see what the temps are like after. Once I find out how to...

cheers.
 
i got that case and like you aren't entirely happy with the noise.

long term i think fan controller might be the way to go.
short term, i'll probably try them 7Volt modded.

but i have tried just disconnecting them both.
obviously that fixed the noise problem, but system temp only went up a couple of degrees. cpu temp didn't seem to change at all (so maybe up by a degree but as the temp was fluctuating by a degree anyway, hard to be sure).

i was dual Prime95ing at the time, though was running my X2 3800 at stock.

maybe try disconnecting just one of them (front one), might improve the noise situation without adversely effecting temps.
 
The PC7 does not have completely cfm dependant airflow like all Lian Li cases of recent years, it is perfectly fine to run passive, but volt modding the fans is the way to go.

In my opinion if you are going for low noise, then you need to volt mod the fans, no matter what they are.
 
The temps are completely as before - so that's great.

The case has the black ones. I had to shop around to get the case with 120 mm fans. I asked Overclockers but they told me it was definitely as advertised (ie 80, 120 mm) - which is strange of them to say so if everyone is getting the new cases, as they lost a sale.
 
i only asked as i have the white fans in the pc7+ and am fidning them slightly loud ordered some ambers now so will see if its the fans or my hearing being over sensitive
