help me lower AVC Sun flower fan speed

[r0l0e]

hi all,

although the AVC Sun Flower is a very nice and good looking product, the noise level is a bit irritating at over 5000rpm. is there a way to mod it like the volcano 7+?

Well...... you can just do a 7v mod on it---
Simply take the 3pin connector--- cut the red and the black flush to the connector----- (leave the sensor so it will tell speeds)- find an old female molex connector and wire the black to the red molex wire and wire the red wire from the fan to the yellow molex wire and Presto! It works and its 1/2 the noise!

You don't have to cut any wires. There is a little square of the contact pin exposed on the side of the connector, just push in with a small tip flathead screwdriver and pull the wire out.

The 7V mod does help reduce noise, Spyder is probably correct in stating that it would be about half as loud, but it also reduces the cooling level. It may be preferable to use a 10V fixed linear regulator, or to make some type of adjustable regulator(linear or switching). Rheostats work too, but they are of a mechanical nature which means they are more likely to fail and cause serious system damage.

best bet for fan controllers are Macromans PWM controllers at www.bit-tech.net

Bit harder to make than some but well worth the effort.

You'd think some company would have come up with an all in one PWM IC that just reads the analog output of the internal diod, then you just drop in a CPU, install the HSF, and set the maximum temperature in the BIOS. I guess you can't get everything you wish for . . .

the 7v mod is nice, but i'll like to have more controll on the speed when i'm doing some heavy rendering or gaming.

i was thinking somewhere along the lines of a fan bus. that's where the volcano 7+ is handy. at idle (26c) i use the lowest setting, but when i game, i switch it to medium speed.

thanks Holst, ,i'll try the fan controller. btw, there is a new Sun Flower with fan controllers. it's just too bad it wasn't available.

have your tried speedfan?
controll the speed of the CPU on the FLY (based on heat)
works great if it supports your chipset
