rpm on TT Smart Fan 2

01_VTEC SE · Jun 30, 2003

my Abit NF7-S reports that my rpm is only ~2300 on full and less than 1000 on low. I thought they were rated at 4800rpm??? Is something wrong with mine?

oh and it's not loud at all

What are the temps at?

BrianS · Jun 30, 2003

you must be using the temperature control instead of the manual switch. 4800rpm is DEFINITELY LOUD!!!! i have one, and this is one reason i went watercooling!

I don't think there's really anything wrong. My mobo does the sames thing basically with my case fan. I just think that some mobos have a problem with the tracking of RPM's mine shows between 2200 - 5500 up and down all the time. just a glitch.

that's what I thought too, but I tried both......

it's no where near the 60mm delta's (just for comparision)

I'll check the temps when I get home today

uhh...no

he'd be able to tell if it was running right, there is a huge difference in sound from 2200 to 5k

Have you taken it off a mobo header?

Kdog154 · Jun 30, 2003

Connect it directly to a PSU molex connector. My Tt SF II does the same thing when I use the 3 pin connector and connect it to the motherboard.

01_VTEC SE · Jun 30, 2003

I didn't even try the mobo header

I learned NOT to use it in my delta 60mm days

I'm stumped, unless this fan is defective

Is it still slow with the bue jumper in place?

what are you using to monitor the rpms?

the bios..... but the fan doesn't seem loud at all, maybe I'm deaf??

Robin Hood · Jun 30, 2003

The fan ships with a blue jumper in place which sets it to max rpm.

my fiancée has two of those loud bastages in her dually. thank god i found the adjustable pots, yeesh!

I have one of those...I'm thinking about switching back to the thermal prob sensor thingy magiga those SOB's are low....compared to the other fan I had..

as far as the jumpers there should be a 2 or 3 pin connection on the fan but I can't quite remember which it is (2 or 3) but thats where the blue jumper goes...full RPM.s you shall be amazed at the difference.

Remove both the manual and sensor controls. One of them (I think it was the sensor) was connected to two pins - jump those.

This should let you now if it is the fan or manual control at fault.

i tried that just now...... the rpms don't go above 2360
just as a reference, I can sleep on my desk with the case open (it's not loud at all)
