Silencing Scythe Mugen 2
What is the fan that comes with it? Would a slip stream 1200 for example be a more quiet option for it?
It's a Slip Stream 1200RPM, though it's a PWM version.
From the stock fan testing in the SPCR review of the Mugen-2:

Overall the fan is excellent just like previous Slip Streams. As far as stock fans go, it is one of the best acoustically.

Yeah the Mugen 2's stock fan is actually pretty decent. Probably too loud for a lot of people on this site at 1200RPM, but if you use PWM and let your motherboard control the fan speed, it probably won't ever run that fast. If you have fan control off and are just letting it run at full speed 24/7, though, I could understand how the noise would be unacceptable.
I have two GT 1850 rpm @ 7v in pull/push and temps never raise 52ºC playing games with almost 33ºC inside my bedroom.Leopardi wrote:I turned on PWM from bios and now it's quiet. But in gaming it boosts back to the 1400RPM. Would a GT 1150rpm be sufficient while keeping the max volume acceptable?
I have a Phenom II 955 undervolted to 1.22 v and OC to 3.3 Ghz.

That's from Xbit Labs.

Do you have a Gigabyte motherboard? That's one thing I really don't like about mine, the PWM profile for the CPU fan is way too aggressive, it ramps up too much (usually to 100%) under load even though CPU temps aren't that high. They need to include an option in the BIOS to switch between "aggressive" and "quiet" profiles. Even my budget ASRock motherboard I owned before this Gigabyte had different profiles for the automatic fan speed control.Leopardi wrote:I turned on PWM from bios and now it's quiet.

Anyway, you could use software like Speedfan to control the fan speed and prevent it from ramping up to full. Or just replace the fan with something that tops out at 800-1000RPM or so, should stay pretty quiet.
@frostedflakes, no Asus Crosshair IV. Now that I checked better there's options and I can select the max speed for it manually as well so it stays at ~1000RPM at full load too.danimal wrote:mount a second fan on your mugen2, it'll help keep the temps down.
do not replace the factory fan, there is nothing better on the market, the rpm range is designed for match high-performance useage... if you put a weak fan on there, the cooler will run hotter.

It makes a high pitched noise and it annoys me so I think I have to change it now. A GT 1150 should perform similar to the slipstream 1200 right?danimal wrote:mount a second fan on your mugen2, it'll help keep the temps down.

it sounds like your fan is defective, or maybe it's mounted so that it's resting(and vibrating) on the ram chip? are you absolutely 100% positive that it's the cpu fan? stick your finger in the fan, and the noise stops? is it running under pwm control, or do you have it running full-speed all the time?
because as Tephras said earlier, there isn't much better for the high-impedance mugen2.

This is quite different from our experience. The fan of the Mugen 2 was described in our review at ~800rpm: "The fan sounds smooth as silk, with almost no bearing noise. At 9V the noise characteristics rival that of the Nexus fan." It measured just 12 dBA/1m. Even at ~1000rpm, it's very quiet, just 15 dBA/1m and almost entirely just turbulence (random) noise.Leopardi wrote:I tested it with fan controller and the high pitched whine gets much louder as I turn the fan higher and gets more silent as I turn it down.
Also the whine sounds clearly louder when I close the case?
I have pinpointed a new noise source down to my PSU which is Enermax Modu82+ 525W. A tinnitus like super high pitched whine... it also audibly rattles when it's on the 30-60 seconds after shut down. I'm going to have to buy a new one.
the scythe goes very silent at ~500rpm and it's the PSU whining over all components. But at already at ~800rpm it gives similar high pitched noise as if it was my former Tri-Cool running at medium, but just farther away. Not nearly as annoying as the PSU whine though.
