Coolermaster 90CFM 19dBA 2kRPM fans

[leathal]

I just got my 20 fans yesterday from Singapore, and plugged one to to try it out as many of you stated before that at 2k RPM there is not way the fan would be 19dBA, well your wrong.

I used my Panasonic RR-US430 pocket digital recorder to record the sound of the fan at close and 1/2 a foot a away after dampening the sound in my room as much as I could. My current machine is loud enough that it would probably add a couple of 2dBA to the overall sound I recorded. The problem now is getting the audio off the recorder as I lost the CD that goes with it and Panasonic doesn't make it available on their site!!! (SIGH)

So either I will get it next week and upload the wavs here or everyone will have to wait until I get my Blackberry Bold! :-)

Here are some pictures of one of the fans.

The next plan for me is to order a case from mountain mods, and RADs. I see from galery that everyone who has bought a UFO case of some sort has bought a black one, after having a few black cases in my PC career and seeing how they are attracted to scratches I am going with the white powder coated case.

Then have to experiment with my own custom flow system.

They look pretty, but will wait on further opinion/testing.

Sure, anything you say...

i had some 100+cfm coolermaster led fans rated at 16.5db (at silent mode)
i have to mention that at silent mode they were inaudible..
however at full speed i wasnt impressed at all..the pressure seems to be very low and its quite ineffective on a rad

Oh... and you got 100+ cfm from the fan and it produced only 16.5 dB at the same time, right ?

I don't know how the OP can be so naive

Quick.. let's throw out the San Ace fans !!! Those stink compared to these Coolermasters !!

[leathal]

well if those specs are true that would be the holy grail of fans..
maybe vapor knows something about these fans..

Again...

The number of blades and their design is the primary key to any fans performance, rotational speed obviously helps but isn't as important.

At the end of the day it comes down to what the application requirements are.

If you want to test the coolermaster fans I bought the only place you are going to find them is in New Zealand and in Singapore. Coolermaster doesn't make them in the USA and has no intention in doing so at they feel the US market application requirements are different.

Hehehehe... I *am* Singaporean and I have a steady supply of hardware coming from Singapore The next shipment within 2 weeks. But I have a faster way of finding out .. my brother is there and works right next to the SLS computer mall

So stop being a whimp and go get one and do some testing.

Have to done any write up's on these fans? Lets see it!

As i said it was rated at 16.5db at silent mode..obviously it doesnt produce 100+cfm at silent mode..at full speed mode it was rated at 100+cfm..

The main point i wanted to make in my previous post is that coolermaster fans are not suitable for rads

[IanY]

I will know in about 10 hours when my brother wakes up with a hang over from his Saturday partying.

Obviously.. sorry the sacarsm it wasn't aimed at you... it was at the OP.

My apologies.

[IanY]

Here... 31 pages of forum thread on a fan, just to conclude that its ratings are bogus and its radiator performance is weak.

This is an elementary review of the 70 cfm version

After replacing 1x case fan from the NZXT Alpha & the TT BigTyp VX cooler while the TT fan replaced the original exhaust fan of the NZXT chasis, I expect to bring the CPU temp down .
But I was disappointed.
On idling, it showed improvement of 2'C but onload it's few deg higher than previous setup.
Think tonight I'll have to swap the exhaust fan & the CPU fan, confirmed the TT one has a stronger airflow though it's rated 86cfm. Wonder how & base on what CM rate it as 90cfm?

[Eddie3dfx]

You have to understand why people are sceptical.
Tons of testing.studying has been done on fans and then all of a sudden coolermaster comes out with a fan that essentially defys everything that has been tested including I'm sure some scientific theories.
Damn, the people are coolermaster must be some sort of alien r&d team

[IanY]

Vapor must have reviewed over 100 fans by now, if not more. Anything resembling over 60+ cfm generates a good 33+ dB. The very best San Ace fan generates 105 cfm at 42 dB.

Now, how is 90 cfm at 19 dB remotely possible ?

[Tonucci]

19Db above ambient noise maybe ? I would believe an 19db delta lol No way in hell it double some of the best fans CFM while making less noise.

[Vapor]

leathal got hosed...he could have had 110CFM and 16dBA with Coolermaster's 2500RPM model

In all seriousness though: http://www.xtremesystems.org/forums/...6&postcount=27 (other posts in that thread are pertinent too...like where I quickly TEST the 2500RPM version of the fan just for him)

[Asgard_thor]

I was going to call BS..

my yates
# Air Flow: 88 CFM
# Fan Speed: 2200 RPM
# Noise Level: 40 dBA

[IanY]

19Db above ambient noise maybe ? I would believe an 19db delta lol No way in hell it double some of the best fans CFM while making less noise.

Room ambient in a graveyard is like... 25 dB.. 19 dB puts that into Sunon category !! That's assuming a dead quiet environment. LoL

Well for starters they Coolermaster USA doesn't carry anything on the global Coolermaster site so they are not available in North America unless people are importing them on their own... either way they are not distributed in mass quantity in NA, so not everyone has them or knows about them...

The sites you list are all on the other side of the world!!!

IanY's point was, if they are so great, why are there so many on the shelves where you can get them.

IanY's point was, if they are so great, why are there so many on the shelves where you can get them.

Well there is a couple of simple reason for that:

1. people come to sites like this one to see what other people are using so they go and buy the exact same thing without spending days or weeks looking through the internet trying to figure out what they should get on their own.

2. the fans are only available in Asia and parts of Australia (it seems), it took me about a week to figure out that Coolermaster NL was completely useless when it came to getting any information out of them as to were I could purchase the fans from. It it took more time to find a place in Asia that would ship the fans to Canada (were I am located). So do you think people abroad would go to the extent I have had to go to get 20 fans? Probably not!

3. WC'ers and AC'ers are too skeptical when it comes to technology to try out new things, all the posts I have seen on this site and the one IanY posted suggest people are more willing to say the possibility the fans are 19dBA is a load of crap instead of buying and testing a new $12/$14 piece of technology.

So you guys can believe what you want, but I have the fans (all 20) in hand and so far I can tell you the are super quiet but push a lot of air; since I don't have millions to spend on a dBA meter I can't really test it but they are certainly a lot quieter than the Coolermaster clear LED blue 120mm fans I have in my Thermaltake case right now.

You can argue to disagree or disgree to argue, idc!

Dude, you're absolutely unequivocally retarded if you think 90cfm or above can be generated with 19dba.

[WhiteFireDragon]

well if you have so many, send or sell one to vapor or martin so they can use the same testing methods to test it like all the other fans. then a true comparison can be made. this is the internet, so you can claim anything you want without proper testing methods, and no one will believe you

oh btw, i have some secrete fans named XXXX too that produce a tornado, at only 7dba

I don't need it...I have the 2500RPM version of the fan that's rated at 110CFM and 16dBA (well, this one has dual ball bearings rather than sleeve bearings at least). In fact...the review might be up tonight.

I did post a mini-preview of it in another thread.
