Low-Speed vs. Undervolting Fans

post #1 of 9
Thread Starter 
If there's another thread asking this question, just direct me to it. I couldn't find one with this specific question.

I'm considering fans for a case upgrade. I'm stuck between these two ideas.

1. Getting slow, quiet fans such as Nexus Basics.
Pros: Quiet, simple.
Cons: No option for greater cooling if needed.
2. Getting higher-speed fans with a nice sound character, such as S-Flexes, and undervolting them.
Pros: Extra cooling power when needed.
Cons: Requires fan controller, etc.
So, what fans undervolt well? They don't need to be silent, they just need to be quiet and not rattle or make annoying noises.

I'd make it as painless as possible and get the low speed fans. Yate Loon low speeds make good/inexpensive case fans. Spend the money on better fans if you're putting them on an air cooler or a radiator.

This actually makes a lot of sense. You can get a low speed and a high speed Yates for $12 from Petra Tech. You will spend about $15 or more to get a Gentle Typhoon, which is the fan that is most throttlable.

S-Flexes are very picky about controllers. Only the best $30 controller will handle them without causing them to make noise.

Most fans click when undervolted. The exceptions include the Gentle Typhoon, the RFX-120, and the Thermaltake A2018. These three work fine even with the cheapest of voltage controllers. In fact, the latter two come with their own controllers.

I don't use fan controllers. OTOH, I can afford a large collection of Gentle Typhoons, which are the best overall fans. The multiple Yate Loon suggestion is the best. They work great.

Look at item 1 in my sig to see fan comparisons.

Ok, so are all Gentle Typhoons good to undervolt? Or is it based on luck? If there's a chance I'll get bad ones, then I'd just get Nexuses or Yates.

I have sixteen GT's, 500 rpm, 800 rpm, 1150 rpm, 1450 rpm and 1850 rpm. I've yet to hear a single click from any of them.

i beleive frozencpu.com has the 1450 gt's in stock right now. these are very quiet and still move a good amount of air. when i bought my gt's i was torn between the decision of buying 4 ap-14s or 4 ap-15's. i ended up getting 4 ap-15's and 1 ap-14. if needed i can always use one of my noctua lna adapters on any of the ap-15's to bring the rpm down a bit.

but i think you will find that the ap-14's have the best air movement to noise ratio.
