Ah kk.
I assumed every fan going at the same rpm (or having same cfm) has the same noise lvl.

RPM is Revolutions Per Minute. It's how fast the fan is spinning. CFM is Cubic Feet Per minute. It's how much air the fan can supposedly move, which depends on the number of fan blades and the design of those blades. At 1200 RPM, a 120mm fan should be nearly dead silent.

I find 1000rpm to be near silent. 1100rpm is as loud as I find comfortable..1200rom is not comfortable to me.

dBA sound level of a fan is takes in open use, not mounted in a case or on a cooler. In actual use the dBA (noise) goes up because of resistance to airflow and the added noise of airflow through whatever is creating the resistance (grill, filter, cooler).

Ok, well I'm just going by my fans. I don't hear anything other than a very quiet humming (I'm told that it's from the bearings). Even if I put my ear right up to them, all I hear is just a very gentle whisper of the fan blades. What fans do I have? The cheap stock ones that came with the Cooler Master CM 690. Well actually, I have some "neon LED" equivalents, but they are the same fans; same blade shape and design, same number of blades, same specs, etc. etc. etc. So, I dunno, maybe they are a lot nicer than I think. I mean damn.

at the moment, my corsair 200R stock fans are really loud. i can hear them when im standing 6 feet away.

according to HWmontior, they are only running at 1300 RPM (Idle)

ill come back to this thread after I install my 2 sp120l fans and test them out.

but going back to my post 2 posts up,
yeah, i thought that dBA goes up proportionally, meaning if 1 fan has a dBA for x at y RPM, then every fan will also have a dBA of x at y RPM.

didnt realize it differs biggrin.gif which is great news for me lol

Fans are just like anything: they're not all the same. There are lots of different fan designs out there.

Same volume of sound but the difference in sound can make a big difference in how we perceive it. . is it pleasant to the ears or is it irritating?

Since the 4th pin is what determines the controlling of RPM,
do you need 4 pin fans to use with a fan controller?
if u use a 3 pin fan with a fan controller, will the fan run at full power all the time?

You need 4-pin fans to use PWM control.
3-pin fans plugged into a 4-pin PWM controlled header will run full speed... BUT some motherboards have both voltage control and PWM control on CPU fan header... some automatically recognize if fan is PWM or voltage control... some must be set in Bios... some only supply PWM.

I know of only one PWM fan controller. Aqua Computer have the aquaero line but they are not cheap.

I'm not entirely sure on details - it's not an issue with any type of air cooling, or water - i think the first time you'd run into it was if you were hanging a water radiator out of a window with a significant temperature difference inside vs out

*This isn't possible without some kind of below-ambient cooling like a water chiller. What video's are you watching? tongue.gif

As for psu, you're fine.

@1.4v on cpu and 1.212v on gpu, your gaming consumption will fall right where you want it to on a 450w unit. A 760 is about half of a 780, remember.

Your temps are not too low, my idles have been below 20 at times. How low they go depend on the idle state you go to (c6/c7 is basically 0 power usage) as well as if you have integrated graphics enabled or disabled, what cooling you have mounted and how good the mount/contact is - that stuff tells you how much hotter than case temperature your idle will be. Lowering your case temperature by 10 degrees will cut 10 degrees off your idle, etc.

Your room temp in F (always use C, don't randomly jump between C and F..) is ~23c, so it's a quite normal idle temp. Your case temperature is likely a few C over room, even at idle. At load without perfect airflow, it's likely to climb a bit more.


As for overclocking, yes, you have to change voltage. It's not a good value proposition to pay extra for "k" CPU and z87 board (like $100 more than what you paid for your board, no? iirc like $30 after rebate) and to not buy a cooler, otherwise performance gain is just too small. Increasing voltages is an integral part of overclocking.

I'd suggest you read the haswell overclocking guide on OCN, made by darkwizzie. Average OC is ~4.5ghz @1.3vcore

I FOUND THE VIDEO FINALLY !! lol
http://www.youtube.com/watch?v=VuP6I0mOb1s

at about the 2:40 mark

can u explain what he meant? since he jsut straight out said "condensation occurs if your temp is lower than ambient temp"
