well, i just got my new aplha heatsink, (PAL 6035), with a delta 38cfm fan. i plugged it in and checked it out. cools alright, about the same as my orb (the design of my case works really well with an orb actually, because airflow goes across heatsink). anyway... i check out my RPM's and see something very interesting. 16,700! wow. thats hauling a**. that was also with case open, and a fan blowing on it... with case closed, and all my fans running, it only ("only") does 13,600 RPM. (but if i have my YS tech 112CFM going right above it, it gets back up in the 15's).
is this right? my RPM meter has always been fairly accurate. currently, it monitors 2 other fans, and they are right. my orb registered right also....
i have even swapped it to different plugs on mobo. am i just lucky to get a DAMN fast delta?
wow..even for that delta, that's about twice as fast as normal...
what're you using to test that?
I personally don't see how you could've gotten such a fast fan, or how you could stand being around such a fan...I think it's a bug in the reporting.....but I'm known to be wrong from time to time (heh)
The sound would be UNBEARABLE! Thats GOT to be an error. The fan would fly off of the berrings and like, stick itself through the side of your case! :)

well, the thing is..... i thought it was an error, but i think it MIGHT be real....
my 112cfm fan, the big'n is LOUD, about three times as loud as an orb. well, the delta is louder than that.... its louder than all others combined.
and, being the curious idiot i am, i took a piece of paper and tried to puck it through the fan, to see how many pieces it could get chopped into... and, well, it spins SO fast, i cant even get a TINY piece through the blades....

sure!
i cant right now becuase im in the middle of changing mobo's.
in about 2-3 days though ill post pics. my system is having issues and im upgrading to the Iwill KK266+ (oh yeah baby!).
i have no doubt the rpm's will be the same. i will post the screenies from mbm though gladly!
ill create a vacuum with 3 fans, the 60mm delta, an 80mm (60cfm), and my 120mm 112cfm :-) i can prolly get it up to 17,000 rpms if im lucky.
its nuts fast though. i immediately got a fan guard for it though. that could kill !

thats bs.. u got a setting wrong in mbm5.. im sorry.. i may be wrong.. but may delta goes 6900 with a fan blowing on it.. but i higher doubt urs would make 16000+, either ur giving it like 20volts and overloading it or something.. that story to me would be like me saying an aline took me to mars last nite and probed me..

yea, i have the basic 60mm one.. 6800rpm gives bout 43cfm.. so i still think he's crazy or the rpm readout is wrong..

im not crazy. its either my board is reporting it wrong, or it REALLY is going that fast.
like i said, getting new board thursday. ill post screenshots of that. going from asus a7v to iwill kk266+. two totally different (and well respected) boards. if both report same error, then i dunno...

heh, i didnt mean to be hard... im not all smart into computers but i know enough.. and i just hate when i come across ppl that think they know this, when i know there surly wrong. your not one of those ppl.. besides it was hot today and i wasnt thinking clearly.. sorry if i came off to rude.. bet on false rpm readout.. i cant even get mbm5 to work right on my mobo.. so that shows you im not a total geek, just a wannabe =)
good luck with the new mobo.. and if u get same readout.. contact me and you can prove me wrong.... (you know you want to)
Hey if all else fails you can use it for a salad shooter when you - it slices it dices it will shred small house hold animals!!!
Hey... if they made a fan that went above like 20,000 RPMs, could you still hear it? Other than what sounds like an air compressor on overload......
Hope if it IS running that fast, it was designed to, and isn't going to fly apart in 10 seconds.....

i cant wait to get my new mobo to test it.
i should be posting MAD stuff in here. gonna drive my tbird 800 to the limits. had it at 1GB steady, at 32C FULL LOAD. hehe. its gonna get fun.
ill take many screenshots, and a lot of pictures with my digital camera showing my case.
im using a MIDtower, (basically a sideways desktop....) becuase a tower is too big. yet i am using 2 cdroms, and 3 HD's, and 3 pci slots... so its not like i have this HUGE empty case. i just have a small little box with MAD airflow.
ill post video of the fan if anyone wants. (got hi-8mmXR video cam with capture abilities). you can hear just how annoyign it is.

i aint all that nloageably bout fans, but i believe the tach (rpm meater) is on the fan, not the mobo

very true... its a magnetic reader kinda thing... it measures the magnetic field fluctuations as the motor spins. however, the mobo could be reading this wrong.
There's got to be some sort of bug along the way. Since MBM get's it's readings from the system monitor IC on the motherboard, either MBM is set to recieve from the wrong kind of chip (it's an option, make sure you have the right one) or there's something wrong with the fan/monitor IC.
Check out what the fan reading in the BIOS is and report it to us if you would be so kind.
Thanks!
