Vantec Nexus...my experience

hey all. i just got my vantec nexus yesterday and i put it in this morning. when i ordered it from newegg.com, i had hoped to use it to control my 2 80mm 84cfm case fans that are LOUD. when i got it, i found out that it only uses the small three pin connectors. so...a modifying i went. the nexus says to put one connector going from the motherboard fan power header, to the back of the nexus; and then go from the nexus to the fan you want to power with a 3 pin connector wire. i didn't wanna power my two .75A fans with the mobo header, so i had to think of something. i cut the three pin connector off the end of the supplied wire, and then took a molex connector i removed from one of my fans (explained later), and put it on the end of the wire instead. then i plugged a male molex connector from the psu into that to power the fans. since my fans had 4 pin molex connectors already installed, and a three pin connector from each to monitor rpm with, i had to modify them to plug into the three pin connector of the nexus. so, what i did was i removed the three prong connector from the end of the wire that was supposed to plug into the fan. then i cut the molex connectors off the fans, and connected the reds to the red on the nexus wire, and the black to the blacks. for RPM monitoring on the nexus, i cut the three pin connector off one of the fans, and then attached that yellow wire to the yellow wire of the wire supplied with the nexus. the rpm wire for the other fan i left plugged into the mobo, so progs such as MBM would still be able to monitor it. all worked good so far. the one problem im having thought is that i can't get my fans to run as fast as they did without the nexus. they are 6000RPM fans., but at max, they only run at about 4700. it is sufficient cooling, but i would like to get their full functionality if i ever needed it. i put the cpu probe on the green/brown (i forgot the color) board of the cpu around the core. i think i may have been better off putting it on the heat sink bottom because the nexus reads temps about 8C lower than MBM reads. so, if anyone has feedback or any ways to help me get my fans back to full speed, please post!!

thanks

i just got mine yesterday from mpcparts.com and mine came with adapters... didn't you get any? i love mine... they spin the fans at max speed and also make it silent

When I ordered mine, it came with adaptors. I suggest calling the place you got it from and inquire about the adaptors.

Was it in the clam shell? Or was it just the controller?

is the nexus model with LCD supposed to have the adapters? because that's the one i have.

no, nexus multipanel has no adapters, it requires rpm monitoring to work not to mention that crazy beeping...

oh i thought you were talking about the vantec nexus nxp-201, not the multifunction panel...

yeah...i have the multifunction panel....anyone know why i can't get my full fan speed?

The multifunction panel only goes from 2500-4600 rpms. If you want full control of the fan, I suggest a rheobus or rheostat.

The Nexus works pretty well for the price, but I get an annoying beep once in a while.

Sorry, I was misinformed. I just looked at the booklet that came with the unit and it ranges from 5V-12V. My Smart Fan apparently just goes to 4650rpms@12V (rated 0.7a). Really have no idea why yours doesn't work at full speed.
