120mm fan for radiator

post #1 of 14
Thread Starter 
Hey all,

I'm using a Corsair H60 (first gen) cooler for my CPU and want to replace the fan. The radiator is currently installed on the top of my Phantek Enthoo Pro pulling air into the radiator.

I will be getting a fan or fans from this link -
https://www.pccasegear.com/category/9_510/fans-accessories/fans-by-size-120mm

I am looking for something that is rated as 20-25 dBA and performs well for radiators. My stock fan is currently rated as 30 dBA and cannot be controlled with any software. mad.gif

So does anyone have any recommendations? tongue.gif

Cheers.

(Apologies if there's a thread regarding 120mm fans)

Wow!
Just wow. biggrin.gif
Not in an offensive way mate. Just that what you are asking for is quite possibly impossible. ciarlatano will be along in a few hours (when he gets up in America) to tell you all the problems with CLC radiators (very restrictive and low performance).

Fan's rated dBA doesn't mean much. It is (supposed to be) the noise level of fan in open airflow use. But we don't use fans this way so a fan rated 25dBA in open air with 0.0mm H2O is much louder when it is on a radiator creating a pressure differential is 1.5mmH2O .. and that is without even considering the noise added by airflow through the radiator.

Add that the airflow rating is also open air and the static pressure rating is pressure differential at point air stops flowing and hopefully you see how all these manufacturer's specifications tell us very little about how fan will perform in actual use.

Why can't the current fan be speed controlled?

Our own @geggeg Thermalbench has good fan testing. Testing is done on radiator.

Cyclops has a long running thread of fan testing

Martin's Liquid Lab has lots of good info, but no new fan tests in a couple of years. Not really a problem as many of the best fans were released years ago. Gentle Typhoon are definitely one of the very best.

Cheers for the info. Hopefully next time I don't ask anything silly again biggrin.gif

I bought this CPU Cooler second hand and it came with some random 3pin fan which is why I cannot control the fan with something like speedfan.

Anyway, I appreciate the links. Looks like something I need thumb.gif

Nothing silly about asking questions, especially when we learn from them. thumb.gif
They are only silly if person asking is not open minded in looking at the answers. wink.gif

I was on my first cuppa and it just seemed obvious you were trying very hard to accomplish something with very few 'tools' (knowledge) of how it all worked. The good thing is you want to learn and understand how it all works. thumb.gif

At a guess the 3 wires are power, ground and rpm. What colors are they and what does the plug look like?

I think they might be the official corsair fans. They are black and even the cable is black. - http://www.corsair.com/en-au/hydro-series-h60-cpu-cooler (might be that)

I can choose different levels in the BIOS and set them running at a certain level 24/7 but I can't seem to control it completely with speedfan using either a 4pin or 3pin fan connection on my motherboard.

Anyway, looking at the thread you linked I think I may try out the Noctua NF-P12 PWM in a pull configuration and see how that goes. Seems to be popular and I know for sure I should be able to control the fan speeds correctly.

If you have any control (like you say you have in bios) than the problem is probably not the fan, but the interface between speedfan and bios.

What motherboard do you have?

I replaced my H100i fans with some Noctua NF-F12 PWM fans and it helped allot with noise. I run them with the included fan resistor installed and they are way quieter than the stock Corsair fans while maintaining the same temps. LINK

I'm sure there's some decent alternatives, but these are the best I'v personally tried.

What else have you personally tried?
