Looking to replace 120mm Case Fan

[stilkun]

I am looking to replace my 2x 120mm molex case fan on cheap case as it is currently running on one fan because with two is noisy and cannot be controlled. I have found Artic F12 PWM case fans that fit my needs however I want to hear if there are any decent or good case fan better. The case fan are going to be intake and exhaust that are around £5 each, PWM and does not have LED lights.

While looking for various fan prices on Amazon, I spotted this accidentally priced for Fractual fan:

How are your temps atm and what speed are the fans running at?

I mention that because if they're molex you can set them at 7v by fiddling with and they will be nice and quiet! The PWM fans connected to motherboard headers can also be controlled. They're £3.60 here

Despite its good airflow results, the Arctic Cooling ARCTIC F12 PWM is not a very good fan because it produced a barely audible rustle. The impeller was throbbing slightly, too. This fan is subjectively comfortable at speeds up to 1050 RPM and quiet at speeds up to 830 RPM. That’s a mediocre performance compared to the other tested products.

you can buy inline fan speed controllers to have a bracket on the rear of your PC and a turnable speed controller.

OR

you can buy inline resistors that slow the fan for you

OR

you can buy a couple of top quality beauties from Noctua... which will come with the inline resistors as well to get the speed exactly right.. but be warned. they are lovely.. and expensive.

Ebay is a good bet for cheap case fans...

Idle temp around 36c and full load around 66c. Cannot tell what the RPM speed the exhaust fan are running at. I could fiddle with them but I dislike the front fan because it has bright blue LED lighting up the case. What sounds equals or reachs around 40db?

I did consider fan controller but I prefer to leave the system to decide rather than controlling it. Is there a difference between fan controllers vs motherboard or is it matter of preference on controlling their fans speed?

http://www.scan.co.uk/products/120mm...r-pins-1500rpm do believe there are FAN controllers that allow you to control the FANs the same/similar way as a MoBo (modern MoBo), aka until the temperature at a certain point reaches a certain temperature, the FANs are going at a pre-set speed (usually slower that they default speed).Once the temperature been reached, the FANs speed up (to they default speed aka full speed) until the temperature at a certain point goes below the certain temperature, at which the FANs slow down again.
I had once a controller panel which could do this.Had even TWO thermo meters as well (which you could stick externally anywhere whitin your PC for temperature check/controll).Back when Athlon 64 was good.
Still like todays MoBo FAN controll better.

Thanks. I will probably buy 2 of these. Are Akasa a good brand?

[Bonebreaker777]

I would say it is rather common in the market of IT accessories.
Various controllers, reductions, etc.
For example the above mentioned fans have rubber pins to eliminate vibrations and so on.
If your case can accomodate, you could look into http://www.scan.co.uk/products/140mm...l-ball-bearing as well.

If he's got two front fans then they are probably too close together to use a pair of the thermalright TY14x fans
The ARCTIC F12 PWM is a decent cheap 120mm pWM fan (please note you can also get the F12 in non-PWM so check before you buy)

Akasa is a decent "brand" the OEM of the original Apache fans was Scythe but I'm not sure about the newer ones or the viper fans
If the newer ones are of the same quality they are great fans, a bit loud at full speed but if you're running them under PWM and have it set up well then they will be very quiet (the two I have on my hyper212+ run at a near silent ~850rpm when idle)

The Bitfenix spectre pro PWM would be worth a look http://www.specialtech.co.uk/spshop/...pid-16499.html there is the cheaper non-pro version but the pro is only £2 more

My case with those FANs under regulation is quieter that a Zalman NC1000.I would say they are pretty good. The Akasa FANs are near silent round 900rpm as well. Below that I can only hear my XFX PSU (which I can't regulate sadly).
But about two FANs in the front too close, Pob255 is right, will be no space for TY14x-s.

My case only have 1 front but can optionally add 1 side and 2 top fan if required. Thank you all for the advice, I have not finally decided yet which one of three fans to buy but at least I know which decent ones to get
