Need help Deciding on 120mm Fans - Page 3

post #21 of 25
Well, you just said you picked up a fan controller.
Realize that you can turn down ANY fan you get to near silent.

So my suggestion is to get the highest CFM fans you can get, that still allow you to run them all off of the controller.
Sure these low power, and low noise fans are nice for average loads.
Once you get into heavy stress testing, or benchmarking you will want better heat dissipation.

so then what your saying is that i should not worry about how loud the fan is because i will be turning them down to near silent rpms.

but if i want better performance i can always turn it up.

Well then my next question is:

if im running a single i73960x CPU loop to a 360 rad, and running 5ghz.

How high would i have to turn up the fans on that rad in order to get lowest temperatures possible?

All the way up. biggrin.gif

Heat builds up the longer your system is under load.
You said your going to have five radiators, crap that is nuts.
Then you can imagine if you do not move a ton of air around that case. Heat will build up quick while under a constant full load.

I have never understood the need for silence when heavily overclocking, and your under full load.
Then asking your computer to perform at its best, this does not make any sense.

Its like buying a dragster, and expecting it to be quiet when you hit the strip.

Calculate the power draw of the fans you buy. Each channel on your fan controller will have a load max.
My Sunbeam FC has a max load of 30w per channel for example.

Then get the best CFM fans the controller can power safely.
Keeping in mind, the wider 38mm fans alot of times click when you turn down the speed too low.

If you're interested in quiet running then you have to watch out for the motor noise some fans make at low speeds which can be annoying. The Gentle Typhoon 1450s and 1850s don't have any motor noise at any speed. However the newer versions have a high pitched whine at full speed which was barely noticeable in the older versions, it doesn't bother some people but annoys me. If you're over radded for your heatload (as I am) then you can just leave the fans at the lowest speed they'll go as you'll still get great temps. I'm using Noiseblocker PL2s and the difference between CPU load temps at slow and full speed is about 2-3ºC. The PL2s are about as loud asthe GT1850s and deliver similar airflow to the GT1450s but the wind noise is smooth with none of the whine of the GTs.
