nope, it's a type of Ball-bearing type exclusive to Enermax

oh.ball bearing.great then. I tot it was sleeve bearing

btw, may I ask? What kind of situation only need 2k rpm fan to blow?

lol 2K speed.... OC-ing with Liquid Nitrogen... other than that I don't think I'll have fans spinning at 2K RPM inside my chassis

u can get a 2k rpm fan when u wanted great airflow and dont mind the noise. and i guess u r thinking about CM Sickleflow right? they are actually really noisy and doesnt really push that much amount of advertised air

Yes, the Sickle flow X, 2k rpm .. loud fan, malam cannot sleep. So I took it off and replaced with Bitfenix Spectre

Anyone knows any seller selling 4-pin fan splitter ?

Only place I know of is in the forum GS, custom made Niclasteoh IINM I got one from the Thermaltake Archon SBEx2 accessories pack though

Anybody here uses a Fan controller? Currently looking at the NZXT Sentry Mix 2, but wondering if you guys are using anything else that's nice.

You did comparison for airflow between Sickleflo, Spectre & TB Silence?

How about this?



Sunbeam Rheosmart 6 Fan Controller



Available at PPC
Need to join bulk order with Lucassss @ Pristine.

Which 12cm cooling fan is best as intake fan and can blow to display card! Good airflow and silent! my pc casing intake fan very noisy! i can't sleep well at all!

Hahah. I was in all the bulks bro. PCC, Aquatuning and The newly closed frzencpu one.

But I held off the Fan Controller purchase cuz I wasn't sure. Will check our the Sunbeam. Thanks boss!

airflow = SickleflowX > TB Silence > Spectre

Silence go for Spectre.

the best intake fan would be the Silverstone Air penetrator series... but they will not be quiet from what I gathered from user reviews, what fan are you using now that's noisy?

dont know wat brand fan lah, it come with my casing long time ago... Noctua, Corsair, Cooler Master JetFlo fan ok or not? but i don't know which model is good airflow and silent...

If prefer silent fan maybe can try Noiseblocker or Scythe Gentle Typhoon

I can bet that Noctua, BitFenix, Bequiet, Artic and corsair makes good silent fans, should be okay with any of them

Tried NOiseBlocker, much louder than Noctua, not recommended. If you have fan controller, can use NoiseBlocker to lower rpm around 1000+/-. But the performance delivered in terms of airflow and static pressure is still lower than Noctua. Also to take into account, most fans out there takes more watt/power compared to Noctua (e.g. NF-A14 FLX uses 0.06amps at 12v = 0.72watt. Bitfenix takes almost triple of this, NoiseBlocker at full rpm is 4.5watt (similarly to a HDD power consumption.)

The only limitation I can see with Noctua is oil leakage, since they use oil to reduce friction between the fan blade pillar and the housing of the bearing, there is a risk of leaking oil. I had 1 NF-P14 in my Noctua NH-D14 leak oil, but the 12cm NF-P12 did not have this issue. I had Enermax fans which I used for like 4 years, and does not have this issue. If only Enermax had reduce their power usage similarly to Noctua, I would buy them instead since its much more friendly to clean with their patented pop-out fan blade.

Which model of NoiseBlocker fan you were testing?
I currently have 2 M12P multiframe running, you could say they are louder at full blast because the model im using are 2000RPM fans
As for leaking oil, my Noctua NF-F12 PWM also leaking oil after several months of usage.
Another downside of Noctua fan is, it require high startup voltage especially the 140mm 3 pins model, i had 2 of them, their fans wont even budge until i my CPU started to warm up

Hi Guys ,

Anyone have any idea to reduce the fan noise in the casing?

FYI, i have 5 casing fans (all from Cooler Master) and my Processor is still using stock cooling fan (AMD FX8350).

I have intention to upgrade to liquid cooling for processor but thing is i just bought the processor last year and scared that will void the warranty if change to aftermarket cpu fan.

Any recommendation on this, folks? Suggestions will be highly appreciated~! Thanks
